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..

The Suo match an indoor temperature vulcanization Huo rubber with Huo Qian Ji with other activity the Suo of of the material match reaction for characteristic, at the indoor temperature bottom can immediately hand over allied become flexibility the Huo rubber of the body, the product is divided into list set packing and double set packing two kinds of form.List set cent the indoor temperature vulcanization Huo rubber(brief name gum RTV-1) be a Suo to match a liquid Huo one of the main products in the rubber.Usually from foundation polymer, hand over allied, catalyst, filler and additive etc. to prepare but become.Product packing in seal completely softly the tube, usage hour extrude, contact air empress ability by oneself vulcanization become flexibility body, usage extremely convenience.Vulcanization gum can at(the – be 60 ～s+200 ℃ ) temperature scope long-term usage, have good electricity to insulate function and chemistry stability, ability water, bear ozone, bear weather aging, to variety metals and nonmetal material goodly glued to connect sex.Main used to Tu2 Fu4 of various electronics dollar spare part and electricity equipments, envelopment material insulate, defend tide, quakeproof function;Be the surface protection of the semi-conductor spare part material;Can also conduct and actions seal completely to fill Xi to anticipate and the flexibility glue to connect an etc..

Double set cent indoor temperature vulcanization the Huo rubber(brief name gum RTV-2) there is no gum RTV-1 on usage convenience, but it set cent comparison rich in variety, a species can get variety the vulcanization of the specification function product, and return ability depth vulcanization, as a result drive extensive used for an electronics electric appliances, car, machine, building, spinning, chemical engineering, light work, printing etc. the profession make to insulate, pack, the Qian sew, seal completely, defend tide, anti- earthquake and creation Gun tube of material.In addition have to excellently take off a mold because of the RTV-2, as a result conduct and actions soft mold material a great deal of used for cultural object, handicraft product, toy, electronics electric appliances, machine spare parts...etc. of replication and manufacturing.Organic Huo's sealing completely the typical model of gum application one of the situations is a glass act wall.Gluing glass and aluminum metal alloy frame to connect with the organic Huo structure gum Be outside wall material, flexible sew to then bear to wait gum to do watertightness to seal completely with the organic Huo.Other aspect of application still include to used for the aluminum metal alloy doors and windows and plastic-steel hasp periphery to seal completely, the glass install and move the put together of slot sew, seal completely of rivet and setting bolt:The watertightness of the of the health Jie and pedestal noodles, wall body, furniture of kitchen, bathroom, bathroom seal completely;Aquarium, day Peng, metals crest cover, showroom, counter, protect seal completely of wall plank, colourful steel plate;Used for watertightness between the Gao grade highway tectonic plates Qian to sew to seal completely etc..

The building use to seal completely gum, besides which, ， the RTV also include to used for an aviation aerospace, pit electricity station, electronics, machine, car etc. seal completely of profession material, the organic Huo which used for an electronics dollar a spare part to infuse infuse material and used to soft mold material of organic Huo molding tool gum etc..The demand opposite less of these specieses, whole but at a lot of situation can't be little.
