Seal can be classified according to several methods section shape, curing method, use of the site and its intended use materials. Press sectional shape classification: solid core products can be divided into (round, square, flat-shaped cross-sectional shape), hollow rubber products and metal products, and other complex types. Wherein the seal manufacturers, metal rubber composite seal accounted for more than 60%. For rubber seal section design is crucial. The first is the seal lip shape, size design, lip seals on both sides should be the same size appropriate force from both sides of the window glass of the contact glass. Lip length, thickness should be properly sealed where to sell, too thick, too long to make the glass lift resistance is too large, too thin, too short will cause the glass to get a good guide and sealing, vibration, noise, leaking phenomenon; followed by cross-sectional shape of the bottom, size of the design, the window on a raised section of the steel tank, its role is to assemble the guide groove, so that the bottom of the guide groove section should design the corresponding structures, both easy to mount seal how, also taking advantage of its own elastic sealing strip is attached to the steel guide slot, prevent prolapse; and finally take the side of the outer shape and size, in order to improve the appearance, guides, finishes should fit closely with the body. Ethylene propylene diene monomer (EPDM) seals microwave curing process of forming a seal, 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, good foam evenly, waterproof performance of first-class, anti-ozone, 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, high strength stretching, does not absorb water (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.
