In the adhesive industry profile

In addition to the adhesive technology is simple, fast, efficient and inexpensive, and other characteristics, but also a number of other bonding connections can not be connected to the structure or materials such as metals and the realization of the non-metallic bonding to overcome the cast iron, aluminum welding when the easy - Can not be cast iron and aluminum, steel welding. In some occasions, and can effectively substitute for welding, riveting, threaded connections and other mechanical connections. At present, the application of the adhesive has been infiltrated into all sectors of the national economy, industrial production has become an indispensable technology in the field of high technology in a wide range of applications, such as has been reported: foreign car production in China to use 5 10kg adhesive; Boeing aircraft to meet the bonding area of 2400m2; an aerospace plane needs 30,000 bond ceramic piece.

Classification of adhesives and technology glue

The beginning of this century, due to various types of synthetic resin and synthetic rubber successful development, in particular, a number of representative and phenol-formaldehyde polymer resin, urea-formaldehyde resin, unsaturated resin, epoxy resin, such as the chloroprene rubber production and commercialization, To a modern adhesive glue and the rapid development of technology. Since the 1980s, adhesive bonding and significant technological advances, new high-performance adhesive emerging, and because of the unique adhesive technology, with its extraordinary multi-function, multi-purpose can be achieved. As a result, has been more widely used. The classification of a lot of adhesive, is not unified, there are commonly used:

(1) by chemical composition: This is a more scientific classification, the adhesive will be divided into organic and inorganic adhesives adhesives. Organic adhesives are divided into natural and synthetic adhesives adhesives. There are synthetic resin-based adhesives, rubber-based compound and so on; natural adhesive animals, plants, minerals, natural rubber adhesive, and so on. Inorganic chemical component adhesive according to a phosphate, silicate, sulfate, borate and other.

(2) according to the form: can be divided into solid and liquid adhesive adhesive. A solution-based, emulsion, paste, film, tape, powder, rubber, Glue stick, and so on.

(3) by end-use categories: This structure can be divided into the adhesive, non-structural adhesives and specialty adhesives (such as high temperature, ultra-low temperature, electrical conductivity and thermal conductivity, permeability, sealing, glue in the water, etc.) three categories.

(4) by the application of methods: there is room temperature-curing, heat-solid, hot-melt type of pressure-sensitive type, such as wet-bonding agent. In order to meet the industrial and agricultural production and social life of bonding technology needs of the countries in the development of varieties of adhesives have a lot of effort, the rapid development of a number of fast-curing, one-component, high-strength, high temperature, solvent-free And low-viscosity, non-pollution, energy, multi-function features such as an adhesive. In the synthetic adhesives, the use of molecular design and development of high-performance adhesive; use of grafting copolymer, blending, interpenetrating polymer network (IPM) techniques to improve the performance of the adhesive. The adhesive mechanism of a new progress; sizing equipment and tools, there has been new development. If the adhesive with a combination of mechanical connections, such as glue and brush plating technology to form a new composite repair technology. Since the 1980s, China's adhesive glue and technological development soon, the number of species, increased production, quality has greatly improved, many of the adhesive quality and performance to the world even more than similar-the-art products. Heavenly Creations here in order to "super metal" Putty, for example, reflected from one aspect of our adhesives and adhesive technology. Heavenly Creations "super metal" Putty by polymers with metal powder, ceramic powder, fiber and curing agent composed of two component composite materials, also known as "polymer alloy." It has excellent mechanical properties, wear resistance, corrosion resistance, and its targets have been integrated with similar foreign products that match; there are varieties of general-purpose, wear-and-anti-friction, corrosion-resistant, fast-curing, wet Patch-face, high-strength, electrical conductivity-nine series of 26 Putty can adapt to different conditions and requirements of the bonding and repair.

Heavenly Creations "super metal" Putty application and effect

(1) in equipment maintenance of equipment parts took place when the application of wear and tear, rupture, corrosion, scratches, broken, as well as fuel tanks, water tanks, such as oil pipelines, leakage, leakage, the general bonding technology can be used to repair. TG103 such as Beijing Shougang steel Putty repair imported from Germany 1000t quick forging machine, with anti-friction TG301 Putty for the restoration of the Tianjin Bureau of the fairway imported from Japan dredger 215 hydraulic cylinders, TG801 with high-strength structural adhesive Gearbox bearing hole to repair tanks, TG406, TG416 Putty corrosion-resistant chemical equipment to repair the reactor, and so successful, the user was well received. In Wuhan City, we import from Germany's second-hand equipment 1800t hydraulic press of the core components: severe wear (unilateral wear an average 1.5 ~ 2mm) of the main plunger (diameter Φ879mm, long 3130mm), set lead (diameter Φ875mm, long 500mm ), Sets of pressure (diameter Φ876.5mm, long 210mm) for coating repair, restoration costs of new products is only 1 / 20 to 1 / 25, and the repair took only a few days time, in order to put into operation as soon as possible for a time. For oil, gas storage, chemical equipment plugging sealed; for aluminum, iron box, plastic, glass and steel parts of the rupture. The use of traditional welding, riveting, plating, thermal spraying methods, and so difficult to resolve, we Heavenly Creations "super metal" Putty repair are satisfied with the achieved results. Such as armored vehicles under the engine crankshaft box, aluminum alloy gearbox and crack pipes, tanks, pipes, radiators and so on to repair the leak; for the central television tower in the vicinity of the serious leakage of heating equipment for the factory-4GC Boiler pump on the perforated pipe leakage, TG518, TG528 rapid Putty stick plugging up all the success.

(2) to repair the defective parts and new parts to the new pre-coated cast iron protective coating, cast aluminum, bronze parts, often there will be casting defects, such as porosity, such as trachoma, so to reject rate of 10 to 30% or even up to 50 %. In order to revitalize the deficiencies of the parts are cast, can be used TG101, YG111 iron Putty, TG103 Putty on the steel cast iron, steel casting of large defects to carry out remedial work on the small pore, TG102 iron trachoma is available for Putty to fill; on Aluminum casting defects, general TG104 can be used to repair aluminum Putty; pieces of Copper, used copper TG105 Putty to repair. Many factories make up the application of this sticky repair technology, many casting waste back to life, good economic benefits. Also TG406, TG416 Putty corrosion-resistant parts of the hovercraft easy to pre-corrosion coating a layer of protective coating on the parts played a role in the protection, extended service life.

(3) in settlement of conventional machining difficult to achieve the requirements such as graphite stir in the milk pump magnetic ring, a high precision, by a number of N, S a cross-cutting steel into parts of the ring. As the magnet assemblies were not sufficient magnetic, it must be a magnet for every single magnetic charge, and the combination of magnetic charge should not be over after processing, or magnetic will be greatly reduced. The hardness of steel, processing difficulties, relying on the conventional machining can not be resolved, the use of mechanical processing and bonding technology, a very good solution to this problem and smooth out the process to meet the technical requirements of the magnetic ring stir.

(4) expand the scope of the repair adhesive used in conjunction with other techniques, learn from each other and be able to give full play to the more technical features, the expansion of the scope of repair. Such as: large-scale tank or cylinder piston on the depth of the strain can be used to fill the TG205 wear Putty, and then TG918 Putty conductive coating, the last of electricity in the brush Putty conductive metal layer on the brush. This is the coating technology and brush plating technology used to quickly fill the scratch, but also to show the true color of metal. Adhesive technology and mechanical reinforcement, spot welding reinforcement, glass fiber cloth, and other measures to strengthen the line that can be used with temperature and pressure with the seal plugging. Jiamusi, such as a combine of U.S. imports of aluminum alloy gearbox broke down inadvertently, we have reinforced with steel plates, with bond and repair, and achieved satisfactory results; Wuhan Iron and Steel Company rolling mill roll fracture, with adhesive, Mechanical reinforcement, the three spot with repair techniques, but also successful. The use of adhesive repair techniques, and in many large-scale equipment maintenance and repair of the defects of the new products have made a lot of successful experiences gained huge economic benefits, has been well received and users certainly. Beijing Fangshan, such as large-scale cement factory fan and crankshaft bearings with serious bite, removed the scene to repair bearings, in just one day, reducing downtime for the plant to restore the huge economic losses. Another example is the Beijing water supply bureau of the ozone generator plant Roots blower in the rotation, unilateral wear up to 1mm, seriously affect the air pressure used to repair wear TG205 direct coating curing machine, and then by mechanical processing, only cost a few hundred dollars , With 2 days to 3 on the all-spin to repair and achieved significant economic benefits. Heavenly Creations from the use of "super metal" Putty adhesive repair examples can be proved that the bonding technology in industrial equipment maintenance and repair of the defects of new products in applications such as time-saving, labor-saving, energy, materials, money-saving features such as With a very strong development potential in China's national economy is bound to the construction sector to play an increasing role.
