Adhesives in the chemical industry and the prospects for the development of profiles

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 polymers such as phenolic resin, urea-formaldehyde resin, unsaturated resin, epoxy resin, chlorine Butadiene rubber, and so the production and commercialization to promote 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) according to the 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) according to the method of application: Curing at room temperature are based, thermosetting-type hot-melt, 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 of 1) 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 of gas leakage when 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.
