the purpose and the performance of Natural rubber
Health and natural rubber glue temperature glass of -72 ℃, plastic flow temperature 130 ℃, the beginning of decomposition temperature 200 ℃, intense decomposition temperature 270 ℃. When natural rubber vulcanization, the increase in Tg, it will not happen again flow.
Natural rubber flexibility
Rubber and its cross-linking density is not too high vulcanizate flexibility is high. For example, 0-100 ℃, flexibility in the back between 50-85 ℃, the modulus of elasticity of steel is only 1 / 3000, the elongation up to 1000 percent, stretching to 350%, after the permanent back Deformation of only 15% of natural rubber flexibility relatively high, second only to the common rubber in butadiene rubber.
The strength of natural rubber
In the elastic material, natural rubber, raw rubber, rubber, rubber vulcanization of higher intensity. Vulcanization of rubber is not known as the tensile strength of Green's strength, natural rubber Green strength of up to 1.4 ~ 2.5Mpa, the appropriate strength for the green rubber molding process is necessary. Natural rubber has a higher tear strength, up to 98kN / m, its wear resistance is also good. Natural rubber high mechanical strength because it is self-reinforcing rubber, when the time will stretch along the chain molecules form a crystal orientation of the direction of stress.
The electrical properties of natural rubber
Natural rubber non-polar material is a good insulating material. When natural rubber vulcanization, as a result of the introduction of polar factors, such as sulfur, to promote, etc., so that the insulation performance.
Natural rubber-resistant properties of media
Natural rubber is a non-polar substances, which dissolve in non-polar and non-polar solvent oil. Cyclohexane intolerance natural rubber, gasoline, benzene, and other media, not vulcanized rubber in the above-mentioned medium dissolved, the vulcanized rubber is swelling. Natural rubber is not soluble in the polar acetone, ethanol, not soluble in water, 10% hydrofluoric acid-resistant, 20% of hydrochloric acid, sulfuric acid 30%, 50% sodium hydroxide and so on.
The main use of natural rubber
Natural rubber for its highly flexible and sound insulation, plastic, impermeable trap, tensile and wear characteristics, widely used in industry, agriculture, defense, communications, transportation, machine building, medicine and public health in the field And daily life, and so on, such as transportation, with the tire; industry with the transport belt, belt, a variety of ring; of medical gloves, vascular lose; used in the daily life of the rubber shoes, raincoats, are Nuanshui Dai The main raw materials for rubber manufacturers, defense of the use of aircraft, artillery, tanks, even the most advanced technology in the field of rockets, satellites, spacecraft, space shuttles have to be a lot of rubber parts

Shallow talk the path of the fluorine Huo rubber resistant to cold
The fluorine Huo rubber is 1 kind from the Huo oxygen key formation lord chain, but Zha chain top imply Gao Ju4 Wu4 of three fluorine alkyl, it of come together a method method with two A Ji Huo rubber likeness, use the wreath form Huo oxygen alkane to open wreath to come together what legal system build.The heat-proof of the fluorine Huo rubber and bear the drugs not equal to other fluorine rubber, but because of it lord the chain imply Huo oxygen key, but side Ji top imply a fluorine atom again, it and have both of advantage, as a result can in-60 ℃ -200 ℃ very the breadth of the temperature district usage, and bear fuel oil function excellent, dissolve bulge to the methyl alcohol small, but weakness is physics machine function ratio other fluorine rubber bad.
Say on the Zong and lead key into the Si-O key, double in the cent the lord the chain or at member side chain top lead into the ether key, can exaltation big member of meek, thus at improvement the fluorine rubber resistant to cold of in the meantime reserve fluorine rubber original of characteristic, but because of price expensive, biggest restriction it application and expansion.Therefore at the time of carrying on changing sex making new fluorine rubber to the member chain, rightness original of the price be lower of a series the fluorine rubber carry on resistant to cold of improvement is also have much of necessity.
The rubber counteract
Counteract fluorine rubber with some in general use rubber, special kind rubber, can improvement fluorine rubber flexibility low, resistant to cold bad, the price expensive etc. weakness, acquire function excellent but the cost lower material.Because of the characteristics of the fluorine rubber oneself structure, make total vulcanization system choice more difficulty, and counteract future reunion part lower possess singly of fluorine rubber characteristic, therefore, domestic outside counteract aspect of research open an exhibition not extensive, among them can exaltation fluorine rubber of counteract of resistant to cold system main have the following a few kind.
The fluorine rubber/fluorine ether rubber counteract
Is improvement fluorine rubber of low temperature function, abroad already in 20 centuries the beginning of 70's synthesize a fluorine ether rubber, its low temperature function compare the fluorine rubber have obvious improvement, such as the Viton GLT fluorine ether the Tg of the rubber compare the fluorine rubber F246 lower about 14 ℃ , but its price be higher.Aviation material institute for research in Peking counteract a technique to counteract a little amount fluorine ether rubber to develop a fluorine rubber FX-13 through a rubber, improvement the resistant to cold of the fluorine rubber, its brittleness temperature can reach-45 ℃ , and other physics the machine function be good.Pass to counteract fluorine ether rubber not only availably improvement the resistant to cold of the fluorine rubber, and its price also ratio fluorine ether the rubber consumedly lower.
The fluorine rubber/B C rubber counteract
2 dollars B C rubber and 3 dollars B C rubber all ability and fluorine rubber carry on counteracting to change sex, the research be more is used for four change of C fluorine rubber sex.Compared with four C fluorine rubbers, B C rubber also has very the chemistry stability of Gao, heat-proof, bear to wait, bear water, bear steam and bear many good characteristic of chemicals' etc., but it of the typical model characteristics is to bear a pole to lie quality function better, and low temperature function superior.The fluorine of four the equal to ethylene member of the C fluorine rubber replace thing and C Xi of total gather a thing, so both are constitute structure of likeness, for both of counteract and providing compatibility foundation.According to the data introduction, counteract four C fluorine rubber and 2 dollars or 3 dollars B C rubber, can the resistant to cold of the exaltation four C fluorine rubber and flexibility, improvement process craft function and lower the cost of material.But because of two of pole differ very big, reasonable solve total mix a thing of total vulcanization is to counteract a successful key.
Fluorine rubber/agreeable the type difference E rubber counteract
Will agreeable type 1, 4-gather difference E the fluorine rubber of two Xi and dissimilarity structures counteract and can used for production rubber to seal completely a piece.In this kind counteract the gum, along with fluorine rubber and difference E rubber counteract ratio of variety, counteract the gum can performance dissimilarity of function.When fluorine rubber the content be low at 50, difference E rubber is continuous mutually counteract gum to have good resistant to cold, but it bear oil more bad, should the weakness can pass an adoption accommodation of vulcanization method(such as dynamic state vulcanization method) take into improvement.Adoption dynamic state vulcanization method, reasonable control counteract gum of bear oil, resistant to cold.
The fluorine rubber/Huo rubber counteract
Huo rubber is member lord chain with-Si-O-key is lord, but the side Ji is for a type of line form polymer of organic Ji regiment(main is A Ji), is 1 kind and have no machine and organic property of the high mark bullet body.Because of the special of its member structure, compared with the other rubber, the Huo rubber have excellent heat-proof, flexibility, resistant to cold, goodly take off a mold, electricity, well ventilated and transmit heat sex, watertightness and good temperature stability.Counteract Huo rubber and fluorine rubber, can acquire and two counteract of characteristic gum, obvious improvement the fluorine rubber resistant to cold and flexibility bad of weakness, such as Japan synthesize a rubber company development of the JSR-JENIXF series fluorine rubber/Huo rubber counteract gum to have good heat-proof, resistant to cold, bear oil and bear water and bear fume, and the price be opposite and lower.
Add the increase of accommodation Su
Increasing a Su is , in the resistant to cold rubber that product a formula design in addition to livinging gum, rightness resistant to cold sex influence biggest of match.Research enunciation, join to increase a Su ability exaltation rubber member chain of gentle, thus improvement vulcanization gum of resistant to cold.General join freezing point to lowerly increase a Su, can lower vulcanization gum of the glass turn temperature;Whereas, if increase the freezing point temperature of Su higher, the glass that then can make vulcanization gluey turn a temperature exaltation.From the exaltation vulcanization the gum resistant to cold of the angle set out and increase a Su of choice, have to be full estimate to increase a Su to turn temperature to the glass of influence.
Increase type and dosage of Su, from the species of rubber and product of resistant to cold sex index sign decision of.Join in the resistant to cold the worse pole the rubber appropriate of increase a Su, pass the pole Ji regiment and the interaction of the pole Ji regiment within chain of the pole rubber member of increase the Su, lowered the pole rubber member the function dint of, make member chain the segment be easy to sport, can acquire better low temperature function thus.But say for the fluorine rubber, because of its member structure height stability, adoption general of increase a Su to have no effect it, besides carry on under 200-250 ℃ two vulcanization of increase a Su in the process will vaporize, so can application in the fluorine rubber of increase a Su category extremely limited:A kind of is the usage low and opposite member quality of contain fluorine alkene total gather a thing, that is fluorine wax, Be the increase of fluorine rubber Su.Such as in the difference E rubber and fluorine rubber counteract the system, if join in advance making of the low mark son increase Su Φ NA(from difference E rubber and fluorine rubber the mechanics decline solution to make in specially the structure of the reactor), obvious then exaltation counteract gum of resistant to cold.Another is the adoption contain the fluorine sour ester and turn such as the fluorine F two sour ester Be the increase of fluorine rubber Su.Should kind increase a Su in order to having in the member structure fluorine, have with fluorine rubber better of close with sex, so can improvement match of dispersion and the gum anticipate of process function, but it of the biggest advantage be under the premise that to vulcanization gum of physics machine function have no obvious influence, can obvious improvement fluorine rubber of resistant to cold, make fluorine rubber product can at-50 ℃ temperature bottom usage.
The vulcanization chosen to use accommodation system
Fluorine rubber the vulcanization system for use currently substantially can is divided into 3 types:An, Fen with organic lead oxide.According to data report way, for three love the F246 series fluorine that enrich company's production rubber, be adoption one vulcanized agent Be vulcanization system, regardless choose to use An, Fen or lead oxide vulcanized agent, to the low temperature function of the fluorine rubber influence all isn't very obvious, difference also not big.For the fluorine rubber species and dissimilarity of dissimilarity of vulcanization system match, and adoption dissimilarity of vulcanization the method influence the fluorine rubber resistant to cold to still treat in further research.
Choose to use fill of accommodation
Generally speaking, join to fill can't obvious change rubber of the glass turn change temperature, fill to influence the rubber resistant to cold and be decided by to fill and the rubber structure become in interaction.Activity Tan black grain of the son and rubber member would formation dissimilarity of physics adsorb key and firm chemistry to adsorb key, meeting in the Tan black grain sub- surface formation living gum of adsorb a layer(interface layer), should function and glass Tai of the interface layer living gum of function very close, restriction member chain of sport, make to be adsorb to living gum of the glass turn temperature ascension, bar chain segment Gou type of change, therefore can't hope to join to fill to improvement fluorine rubber of resistant to cold.

What is a fluorine, Huo rubber
Synthesize rubber general can is divided into in general use synthesize rubber and special kind to synthesize 2 types: rubber.In general use synthesize rubber function similar to crude rubber, used for a manufacturing general of rubber product, the special kind synthesize rubber to have to bear heat and bear low temperature, acid-proof alkali etc. advantage and used for special environment more and high technology realm, like aviation, aerospace, military...etc., but the of Jiao Jiao in which be fluorine rubber and Huo rubber.Their development application of beginning all is is soldier work kit, empress because the function be excellent but expansion go to public realm, and quick thorough arrive each section of national economy and people produce life of each link, make production line and the person's living environment get biggest improvement, present vast of development foreground.
A, the fluorine rubber fluorine rubber be a special kind to synthesize flexibility body, it lord the carbon atom on chain or side chain top connect to have the electricity the negative very strong fluorine atom, because of C-F key ability big(485 KJ/mol), and the fluorine atom covalence radius is 0.64 A, equal to C-C key long of half, so fluorine atom can C-C lord the chain nicely shield, assurance the stability of C-C chain, make it have other the rubber can't compare to of excellent function, such as bear oil, bear oil and bear chemicals function, good of physics machine function with bear to wait sex, electricity insulate sex and anti- radiation etc., in the havings synthesize the rubber it comprehensive the function be the best and be so called "rubber king".Main used for creation to bear heat, bear oil and bear rubber of lie the quality product, such as various seal completely a piece, diaphragm, gum tube, plastic cloth etc., can also used to electric wire cortex, antisepsis lining etc..Got in the realms, such as aviation, car, petroleum and chemical engineering...etc. extensive of application.On the military industry, fluorine rubber main used for piece, pipeline and electricity circuit of the seal completely of aerospace, aviation and carrier rocket, satellite, fighter jet, new tank to protect a set of etc., is a national defense point industry in can't act for of key material.
1.The main function of fluorine rubber and application from the lord chain structure top see, the fluorine rubber can is divided into three kinds of basic type:Namely the fluorine carbon rubber, fluorine Huo rubber, fluorine turn the rubber of Lin Mao.Among them regard fluorine carbon rubber as principle, but among them again with be partial to fluorine ethylene with three fluorine chlorine ethylene total gather(1# gum), be partial to fluorine ethylene to gather(2# gum), be partial to fluorine ethylene and six fluorine C Xis with six fluorine C Xis and four fluorine ethylene 3 dollars total gather(3# gum) is lord.
(1)1# fluorine rubber have good of physics machine function and chemistry stability, ability under 200 ℃ long-term usage, 250 ℃ under short date usage;Frailty point is-20 ℃ ~-40 ℃ ;Goodly bear to lie quality function, good to the stability of the organic melting agent, inorganic acid, oxidizing agent function, particularly the acid-proof be excellent;Have best of bear weather and bear ozone function, after the atmosphere win expose for few year, physics machine function variety very tiny, to microorganism of function as well more stability.1# fluorine rubber currently domestic only dawn hospital produce.Main used for a making heat-proof, bear oil, acid-proof rubber product.Such as seal completely a piece, gum tube, gum mat, plastic cloth, tape, book film, fuel tank with immerse Zi ware etc. can also used to lead line of outside protect set and equipments antisepsis lining etc., extensive application at the aviation industry, petroleum industry, car industry, chemistry industry etc. realm.
(2)2# fluorine rubber with 2# fluorine rubber is the rubber species of the biggest fluorine of dosage.Have to goodly store to save a stability, electricity to insulate sex and anti- radiation;Goodly bear oil and bear to lie quality;The vacuum function that is best, can satisfy special situation of demand;Heat-proof good, usually can under 250 ℃ long-term usage, 300 ℃ descend short date usage.
26 fluorine rubber is main to used for heat-proof, bear oil, acid-proof rubber to product making.Such as seal completely a piece, gum a tube, gum mat etc..Product can under 250 ℃ long-term usage, 300 ℃ descend short date usage, it bear oil better than other species fluorine rubber, can used for need to bear oil of situation of parts.Be give examples as follows:Used to a "○ " form turn, the V type seal completely a turn and the oil seal skin bowl, valve door which take metals framework seal completely mat etc..These seal completely material can 250 ℃ temperature descend a long-term work in 200 ~s and 300 ℃ short date work.
In the petroleum industry:The F26 gum seal completely a piece to be use to take off sulphur to equip in the oil refining equipments, natural gas of the artesian well machine up, can in the meantime bear heat, high pressure, oil with strong decay lie quality etc. the Ke engrave in the condition usage.
In the chemistry industry:The F26 seal completely a piece to be use to equalize by sealing completely inorganic acid, organic matter to learn material in the pump, the tube deal with contact, the equipments container.
At building material manufacturing aspect:The F26 can make the cement list camalig pump to seal completely a gum turn and do than the crude rubber of seal completely a turn of service life extension 1000% or so.
(3)3# fluorine rubber has to outstandingly bear heat function, bear oil, especially bear a pair of ester oil, bear chemicals and good physics machine function, satisfaction of lie the electricity function, incombustibility, bear to wait sex and excellent vacuum function and bear radiation;Usually can under 275 ℃ long-term usage, under 320 ℃ short date usage;Bear 1# better than gum of oil, acid-proof;Bear weather, bear ozone and bear radiation, well ventilated and electricity function and bear Ran function and 2# gum close by.Broadly the application is at the realms, such as astronautics, car, machine and petroleum chemical engineering...etc..For example used to the action that the liquid of airplane press system and lubricate system to seal completely material;Used to the material, the oil pipeline way of the electric cable used in oil-field and artesian well equipments of the seal completely of oil-field up;The chemical engineering profession used to the lining of the gentle conjunction, pump...etc. of the equipments, piping or make to bear decay of seal completely material, make into piping, in order to transport or organic melting agent or other have causticity of lie a quality etc..
Two, Huo rubber the organic Huo material is main from the Huo oil, Huo rubber, Huo resin and the Huo alkane accidentally allied four major type constitute, Huo rubber(brief name Huo rubber)'s being a yield be the biggest in the organic Huo product, application most extensive of one big product.It is main to constitute is that the line type of Gao Mo2 Er3's quality gather Huo oxygen alkane.Because the Si-O-Si key be it constitute of basic key type, Huo atom main conjunction A Ji, lead on the side chain go into very few quantity of not saturation Ji regiment, member the function dint be small, the member present spiral form structure, A Ji dynasty outside arrange combine can freedom revolve, so Huo rubber vulcanization empress have to excellently bear Gao, low temperature, bear to wait, Zeng water, electricity insulate characteristicses, such as sex and physiology sloth...etc., in the national defense soldier work, medical treatment hygiene, work agriculture the produce and people of the daily life acquire extensive application.
1.The main function of Huo rubber and application the Huo rubber press it vulcanization temperature, can is divided into heat(heat) vulcanization type and with indoor temperature vulcanization the type be two major types, heat gum main used for manufacturing various Huo rubber product, but indoor temperature gum main is conduct and actions glue to connect and infuse material or molding tool usage.
(1)Hot vulcanization the Huo rubber(HTV) be hot vulcanization the Huo rubber(HTV) be most in the organic Huo product importance of 1 type, the A Ji vinyl Huo rubber(VMQ) be the species of most in the HTV and be so called heat gum.
The A Ji vinyl Huo rubber(living gum) is have no color, have no smelly, not poisonous, have no the machine miscellaneous quality of gum form thing, living gum to press demand to join appropriate of compensation, structure control the , vulcanized agent...etc. help to mix Lian together, then heat a mold to press to model or extrude model, again through two vulcanization make into various product.It product to have good of the electricity insulate sex, anti- electricity Hu, electricity dizzy, electricity the spark ability be strong, watertightness, defend tide, anti- impact dint, anti-vibration good, have physiology sloth, well ventilated sex etc. function.
Main used for sections, such as aviation, appearance, electronics electric appliances, voyage, metallurgy, machine, car and medical treatment hygiene...etc., can do the turn, mat slice of seal completely of various shape, tube, electric cable, can also do human body organ, blood vessel, well ventilated film and rubber molding tool, nicety cast of take off a mold etc..
(2)The indoor temperature vulcanization of the indoor temperature vulcanization Huo rubber(RTV) Huo rubber general include Suo to match a type and add to model two major types.
Add to model indoor temperature gum with have vinyl of the line gather Huo oxygen alkane for foundation gum, take containing the hydrogen Huo oxygen alkane as to hand over allied, go to at the indoor temperature under the catalyst existence medium Wen Xia4 occurrence hand over allied reaction but become flexibility body.It has good heat-proof, Zeng water, electricity to insulate sex, in the meantime because of activity carry lead of Ji go into, make it have excellent of physics machine function, particularly is at anti- piece strength, opposite elongation with tore to pieces strength top to have obvious of exaltation.It is applicable to a variety vulcanization method, such as radiation vulcanization, lead oxide vulcanization and add to model vulcanization, extensive used for heat-proof, defend tide, electricity insulate, Gao strength Huo rubber product etc..

How maintain tire better?
The car run on the road, the tire is an unique contact the part of the ground.Imaginable, this rubber skin be how an importance.The agency friend"big skin bear" ask in the mutual aid commune:"Summer is quick come, four wheel of air pressure should be how much?How see barometer and tire appearance?"
Although is a primer class problem, however enthusiasm answer of the agency friend be not a few."Xiaohao 1999" answer:"The words of small car are 2.5 kilograms, summer had better be a Chong nitrogen spirit, it be a kind of sloth air, under the heat can't inflation."Experience of"light rain 68" is:"Car type different air pressure not kind, the side of the car door contain hint.""Happiness itinerary" also come to recruit:" Buy one piece word manifestation of the foetus press to account very importance and measure a foetus to press at any time."
In fact concerning the tire, your demand attention of the place return not only these.
The foetus press a too good enough to bility would flat tire the foetus press shortage the oil consume a meeting ascension.
You must record:
The foetus press a too good enough to bility would flat tire the foetus press shortage the oil consume a meeting ascension.
The tire air pressure is a car of an importance index sign, regardless higher still low, all would influence tire of service life, even cause traffic accident.
If the foetus ran over foot, the nail, glass...etc. of road noodles sharp thing easy firm go into foetus inside, result in flat tire.Foetus' pressing foot will also make tire and ground contact the area diminish, grasp land productivity to descend, thus influence the car lift soon with brake.Moreover, the air pressure lead the tire of foot would influence avoid earthquake, result in line car to jolt, sit of course not comfortable.
If the foetus press shortage, tire's wear away will become big, the service life shorten, the coefficient of friction of tire and road noodles also immediately enlarge, the oil consume therefore ascension.Experiment manifestation, tire air pressure if low in standard air pressure value 30%, the oil consume will ascension 10%.
The tire is an expendable goods and even open little, would also the nature be aging, so regardless how quality is and the tire be to have certain life span first.Usually tire's using time limit is 2 years or opens 30,000-50,000 kilometers.But also want to see an usage circumstance, if usually open in the neat road noodles, the tire use a little longer.If total at sandy soil road etc. road noodles the north bound drive and use the fee be some.General say come, if when the veins depth of the tire be less than 1.6 millimeters and whet about, need to be changed.Because the tire grasp land productivity to die down at this time, very the influence lift soon with brake.
In actually drive, usually is front empress the foetus ratio the foetus wear away severity.When experienced driver was general to drive 8000-10000 kilometers, meeting in front and back the tire replace once, extension service life.If run into a certain tire to wear away more severe, even appear "drum pack", need to be replaced individual, in order to prevent appear to run to be partial to.
The experienced driver all know that every year cold hot alternation of seasonal changes, should adjust tire air pressure.Because hot bulge cold Suo, the air pressure of tire would variety.Majority the tire of the car standard air pressure BE:The round is a 2.5 kg front the winter, empress round is 2.7 kg;Arrive summer want to adjust for:Front round 2.3 kg, empress round 2.5 kg.However, tire air pressure of concrete standard had better take a look car fanlight hint.
According to elucidation in the book of request finish adjust a tire air pressure, must remember to do a matter:Parking see a tire to have a few wood grain to press on the ground, this be the tire standard air pressure under the appearance of appearance.
Usually open for 12 months, the spirit of tire would be a little bit little and the demand repair spirit at this time.The person sit on the car many or carry amount of thing heavy, will also appear an above circumstance.This demand usually adjust air pressure, the many people is all self-provided the car carry Chong spirit pump etc. tool, oneself can inflate.
Now also have nitrogen to the tire Chong spirit of, because nitrogen spirit not easy hot the bulge cold Suo, suffer indignities variety influence small, summer can decrease flat tire of several rate.However, the Chong nitrogen's spirit's demand spend money, general is 20 dollars Qian2 Yi Ge4's tire.
You must do:
Remember standard air pressure hour the tire has a few wood grain ground.
Tire veins depth less than 1.6 millimeters have to change.
Although is a primer class problem, however enthusiasm answer of the agency friend be not a few."Xiaohao 1999" answer:"The words of small car are 2.5 kilograms, summer had better be a Chong nitrogen spirit, it be a kind of sloth air, under the heat can't inflation."Experience of"light rain 68" is:"Car type different air pressure not kind, the side of the car door contain hint.""Happiness itinerary" also come to recruit:" Buy one piece word manifestation of the foetus press to account very importance and measure a foetus to press at any time."
In fact concerning the tire, your demand attention of the place return not only these.
The foetus press a too good enough to bility would flat tire the foetus press shortage the oil consume a meeting ascension.
You must record:
The foetus press a too good enough to bility would flat tire the foetus press shortage the oil consume a meeting ascension.
The tire air pressure is a car of an importance index sign, regardless higher still low, all would influence tire of service life, even cause traffic accident.
If the foetus ran over foot, the nail, glass...etc. of road noodles sharp thing easy firm go into foetus inside, result in flat tire.Foetus' pressing foot will also make tire and ground contact the area diminish, grasp land productivity to descend, thus influence the car lift soon with brake.Moreover, the air pressure lead the tire of foot would influence avoid earthquake, result in line car to jolt, sit of course not comfortable.
If the foetus press shortage, tire's wear away will become big, the service life shorten, the coefficient of friction of tire and road noodles also immediately enlarge, the oil consume therefore ascension.Experiment manifestation, tire air pressure if low in standard air pressure value 30%, the oil consume will ascension 10%.
The tire is an expendable goods and even open little, would also the nature be aging, so regardless how quality is and the tire be to have certain life span first.Usually tire's using time limit is 2 years or opens 30,000-50,000 kilometers.But also want to see an usage circumstance, if usually open in the neat road noodles, the tire use a little longer.If total at sandy soil road etc. road noodles the north bound drive and use the fee be some.General say come, if when the veins depth of the tire be less than 1.6 millimeters and whet about, need to be changed.Because the tire grasp land productivity to die down at this time, very the influence lift soon with brake.
In actually drive, usually is front empress the foetus ratio the foetus wear away severity.When experienced driver was general to drive 8000-10000 kilometers, meeting in front and back the tire replace once, extension service life.If run into a certain tire to wear away more severe, even appear "drum pack", need to be replaced individual, in order to prevent appear to run to be partial to.
The experienced driver all know that every year cold hot alternation of seasonal changes, should adjust tire air pressure.Because hot bulge cold Suo, the air pressure of tire would variety.Majority the tire of the car standard air pressure BE:The round is a 2.5 kg front the winter, empress round is 2.7 kg;Arrive summer want to adjust for:Front round 2.3 kg, empress round 2.5 kg.However, tire air pressure of concrete standard had better take a look car fanlight hint.
According to elucidation in the book of request finish adjust a tire air pressure, must remember to do a matter:Parking see a tire to have a few wood grain to press on the ground, this be the tire standard air pressure under the appearance of appearance.
Usually open for 12 months, the spirit of tire would be a little bit little and the demand repair spirit at this time.The person sit on the car many or carry amount of thing heavy, will also appear an above circumstance.This demand usually adjust air pressure, the many people is all self-provided the car carry Chong spirit pump etc. tool, oneself can inflate.
Now also have nitrogen to the tire Chong spirit of, because nitrogen spirit not easy hot the bulge cold Suo, suffer indignities variety influence small, summer can decrease flat tire of several rate.However, the Chong nitrogen's spirit's demand spend money, general is 20 dollars Qian2 Yi Ge4's tire.

Why does the wood grain that is on the tire have no standard pattern?
Why do car and motorcycle tire produce a company to continuously release the tire wood grain of various each kind pattern?My observation arrive a tire of design seem to be all different.Why have no a standard pattern?
The car tire wood grain only have two kinds of physics request:One is have to provide acceleration and brake need of lead dint, two is to have to can open the water Nian of road noodles, in order to prevent tire at contact wet slippery road noodles dozen slippery, result in the vehicle lose control.
The simple piece form wood grain is advantageous to the start of vehicle very much, but piece the forepart of the form wood grain and empress the department wear away more quick.
Circumference raised carving plus the dentation cave slot, can under the circumstance that not increment whole wear away provide additional of lead dint, but regularity partition of ten word form foetus noodles would creation very big of noise, therefore design general adoption anomaly of wood grain.
At medium under rain environment, car with 100,000 meter each of when the speed drive, tire each have to expel 5 premium on currencies, in order to assurance and road noodles of contact.Ten word forms in the tire slice water the row open from the road surface, and pass the cave slot in the on the side raised carving to spray water toward one side.
As for motorcycle tire, top of oval ten words piece the noodles can naturally cut open surface, therefore few emergence dozen slippery phenomenon.And say for the pilot, because of other design noise very big, but this kind of design noise isn't a problem.So, the design be only to need consideration to lead dint.

The differentiation of TPU and PU
The TPU(the hot Su gather ammonia ester flexibility body) is a newly arisen plastics species, because of the TPU have to goodly process sex and bear to wait sex, environmental protection, drive extensive application at the shoe material, tube material, thin film, roll the related profession of the round, electric cable electric wire...etc..Gather ammonia ester hot Su flexibility body again call hot the Su gather ammonia ester rubber, brief name TPU, is a kind(AB) of Qian segment line polymer, AN is Gao the polyester of the molecular weight(1000-6000) or gather ether, B for contain 2-12 keep chain carbon atom of two Chun, the chemistry structure of the AB chain segment is to use two difference the cyanic acid ester be usually a MDI conjunction.General structure type for see diagram.The hot Su gather ammonia ester rubber to depend a member hydrogen key to hand over allied or big member chain light the degree hand over allied, along with go up of temperature or lower, this 2 kinds hand over allied the structure have can negative.Die down the meltdown appearance or the aqua appearance member dint, but cool off or after melting agent vaporize again have a strong member dint conjunction together, instauration original solid of function.
Gather ammonia ester hot Su flexibility the body have a polyester type and gather ether type 2 types, white have no rule globosity or pillar form grain, opposite density 1.10-1.25, gather an ether type opposite density smaller than polyester type.Gather an ether type glass to turn temperature to 100.6-106.1 ℃ , the polyester type glass turn temperature 108.9-122.8 ℃ .Gather the brittleness temperature of ether type and polyester type low in-62 ℃ , the hard ether type bear low temperature sorrow at the polyester type.
Gather ammonia ester hot Su flexibility the body outstanding characteristics is to bear to whet sex excellent, bear ozone best, degree of hardness big, strength Gao, flexibility good, bear low temperature, goodly bore oil and bore chemicals and bore environment function, gather an ether type ester water solution stability far above the polyester type in the damp environment.
Gather ammonia ester a hot Su flexibility body not poisonous, tasteless, can be dissolve in A B to go together with, wreath F Tong, four hydrogen Mao Nans, two oxygens six wreath, two A Ji A Mao An etc. melting agent, also ability dissolve at the methyl benzene, acetic acid B ester, D Tong, acetone with appropriate the comparison constitute of mixture melting agent in, present have no the color transparent appearance, more and so store to save a stability.
The PU gather ammonia ester, from two difference cyanic acid ester or many difference cyanic acid ester with take to have 2 above the compound of the Qian Ji reaction born high mark son the generic name of the compound, it lord chain top imply many regiment of NHCOO Ji for repeat.In common use of two difference cyanic acid the ester have methyl benzene two difference cyanic acid ester(TDI), two benzene methanes two difference cyanic acid ester(MDI), F two difference cyanic acid ester(HDI), difference Fo Er Tong two difference cyanic acid ester(IPDI), two wreath F Ji methane two difference cyanic acid ester(HMDI), many second A Ji many benzene Ji many difference cyanic acid ester(PAPI), benzene two second A Ji two difference cyanic acid ester(XDI) etc..According to the dissimilarity which use Qian Ji a set cent, can is divided into a polyester type with gather an ether type 2 types.Can used for manufacturing plastics to product, bear to whet to synthesize rubber product, synthetic fiber, hard quality and soft foam plastics product, glue and coating etc..
TPU and PU is essentially the same kind of material constitute of.But while doing this two kinds of gum to anticipate.They the formula for use isn't similar.This two kinds of gum anticipate and is divided into a lot of function.
The characteristic that the gum that the different formula does out anticipate isn't similar either.These characteristic is machine characteristic and physics characteristic but say.
