Classification of rubber seal Strip

Classification of rubber seal Strip
Rubber seal can be based on profile, curing methods, using methods such as location and purpose, material classification.
By vulcanization
(1) non-continuous curing method (extrusion tape by a length after cutting, put in autoclave, extrusion molding of rubber semi-finished products into the sulfide in the model);
(2) continuous curing method (microwave continuous curing method, salt baths for continuous vulcanization, hot-air continuous curing method and other methods). A. microwave continuous curing composite seal: microwave curing technology is applied after the energy crisis in the 1970 of the 20th century abroad and been widely promoted production technology. Adoption of technology of microwave continuous curing production consists of a metal core and solid core rubber and sponge materials composite rubber Strip, and, in terms of energy and improve efficiency, device is superior than the other continuous curing method. This technology has been recognized around the world for the production of extruded products the best method. Characteristics of microwave heating is the heat generated in the object to be heated, rather like a regular from external input, not only heating and distribution, improve product quality and greatly shorten the time taken to heat. B. continuous Vulcanized seal salt bath: salt bath containing sulfide nitrite salt bath systems, environmental pollution is large, has gradually been phased out.
Sulphide (Tmax:450 ° c, and Vmax:60m/s) can be achieved using the flame effect of pretreatment, while security is greatly improved.
Second, according to the rubber seal material
Automotive sealing rubber materials having dense rubber, hard rubber and sponge three. Hard rubber hardness up to Shaw of the A95. Sealing compound widely used anti-aging, low temperature resistance, moisture resistance, chemical resistance, especially ozone aging resistance of ethylene-propylene-diene rubber (EPDM). EPDM can be used with steel, steel wire braid, TPE, flannel, flocking, PU coating, silicone coating compound, car interior and the outside world and their own waterproof, dust, noise, heat, vibration, wear and decorative role. EPDM sealing strip can be stable under normal circumstances for more than 10 years. Can also choose has good ozone resistance and good aging resistance in Chloroprene rubber (CR). Taking into account the technological properties of commonly used compound, sometimes used with rubber, natural rubber (NR) and CR, and styrene-butadiene rubber (SBR) three kinds of rubber or polyethylene (PE), EPDM, NR-rubber and to improve ozone resistance.
-Used parts
Automotive sealing strip,
Doors and Windows sealed, ships seal, mechanical seal, three categories which mechanical seals include cabinets, such as seal, container seal.
