Seal can be classified according to several methods section shape, curing method, use of the site and its intended use materials. By vulcanization Category: (1) non-continuous vulcanization (extruded strip by cutting a certain length, into the autoclave curing, the extrusion molding strips into semi-finished model vulcanization); (2) continuous vulcanization (microwave continuous vulcanization, bath continuous vulcanization, hot air continuous vulcanization method, etc. Several methods). A. microwave continuous vulcanization composite seal: microwave curing technology is the application and production technology is widely spread abroad after the 1970s energy crisis. Microwave continuous vulcanization technology can not only produce a metal core, solid rubber and sponge rubber core composite tape a variety of materials, and, in energy conservation, improve work efficiency and other aspects of continuous vulcanization method is superior than the other devices. This technology is recognized worldwide as the best process for the production of extruded products. Microwave heating is characterized by heat generated within the object being heated directly, rather than routine as input from the outside, so the heat is not only fast, but also distribution, will help improve product quality and shorter heating time used. B. salt bath continuous vulcanization Seal: use containing nitrite curing salt bath salt bath system, larger environmental pollution, has gradually be eliminated. C. hot air vulcanization Seal: hot air vulcanization has now developed into a strong wind sulfide, which uses high-temperature, high-speed hot air vulcanization (Tmax: 450 ° C and Vmax: 60m / s) can also be reached flame pretreatment effect sealing strip quotes, and security is greatly improved. Ethylene propylene diene monomer (EPDM) seals microwave curing process forming a smooth surface appearance, has good flexibility and resistance to compression, resistance to weather aging, ozone resistance, resistance to chemical effects and wide temperature range (-40+ 160), excellent performance, car door window has been widely used in other manufacturing industries. Different shapes, different materials, or cold, heat, foam, solid body, as well as products with specific performance requirements, and can meet the design requirements of use. Features: EPDM as raw material, the surface smooth and detailed, good elasticity seal, good foam evenly, waterproof performance of first-class, anti-ozone seal manufacturers, anti-aging, solvent resistance are good. EPDM / rubber / foam series: 1, polyethylene foam rubber expansion joint plate openings (. Caulk board caulking plate) (a) Features ▲ light weight seal species, large retractable strength, non-absorbent (instead of the traditional three oil four felt, bituminous cedar wood plates and other materials). Product environmental protection, simple construction, seepage, leakage, good sealing effect. ▲ corrosion resistance, aging resistance, high temperature + 80 ℃ ~ -45 ℃ not flowing, no distortion, no embrittlement, long service life. ▲ independent opening bubble structure, a special type of joint appearance of the honeycomb plate holes evenly distributed, do not fight hair to the cement / adhesive sealant closely integrated, adapt to the natural expansion and contraction change, enhance joint sealing expansion of the sealing effect. (Ii) application of the product can be widely used in machinery, doors, windows, walls, rivers, dams, ports, docks, underground Chung-dong, water power, airports, bridges and other concrete sealing joint projects. (C) the construction of the product according to the situation using a variety of methods can use the product to use.
