Soft rubber joints and flexible rubber joints, rubber joints, soft rubber joints, rubber shock absorber, shock absorber and rubber expansion joint. Mainly the jgd and KXT several products by inside and outside layer of glue, ply and a steel wire ring composition tubular rubber parts, after high temperature, high pressure vulcanization molding again and metal flange or parallel joints loose combination sets and. This product uses the rubber of high elasticity, high gas, resistance, medium resistance, weather resistance and radiation resistance etc. advantages can reduce the vibration and noise, and the thermal expansion due to temperature change caused by the shrinkage compensation action. It is widely used in a variety of pipe system.
1, natural rubber (NR) with rubber hydrocarbon (polyisoprene), containing a small amount of protein, moisture, resin acid, sugar and inorganic salt. Elastic, high tensile strength, tear resistance and excellent electrical insulation, good wear resistance and drought tolerance, processing of good, easy adhesion is better than most other materials, synthetic rubber in terms of overall performance. The disadvantage is resistant to oxygen and ozone resistance, easy aging deterioration; oil resistance and solvent resistance is not good, the anti acid corrosion resistance and low heat resistance is not high. Temperature range: about ~+80 DEG C - 60. Production of tires, rubber shoes, rubber hose, rubber belt, wire and cable insulation and sheath as well as other common products. Especially suitable for manufacturing the torsional vibration eliminator, engine shock absorber, machine bearings, rubber metal suspension components, diaphragm, molded products.
2, styrene butadiene rubber (SBR) and styrene butadiene copolymer. Close to the performance of natural rubber, is currently the largest production general synthetic rubber, which is characterized by abrasion resistance, aging resistance and heat resistance than natural rubber, natural rubber texture is uniform. Disadvantages are: low elasticity, flex, tear resistant performance is poor; processing performance is poor, especially since viscosity is poor, raw rubber of low intensity. Temperature range: about 50 DEG ~+100 deg. Mainly used to replace natural rubber tire, rubber hose, rubber plate, making shoes and other general products.
3, chloroprene rubber (CR) by chloroprene do monomer emulsion polymerization of polymers. This rubber molecules containing chlorine atom, so compared with other general rubber: it has excellent anti oxygen, ozone resistance, non flammable, the fire can be self extinguishing, oil resistance, solvent, acid and alkali resistance and aging resistance, good air tightness and other advantages; better the physical and mechanical properties are superior to natural rubber, so it can be used as a general purpose rubber, can also be used as special rubber. The main drawback is the poor cold resistance, large proportion, relatively high cost, good electrical insulation, processing is easy to stick rolling, easy to scorch and easy sticking. In addition, rubber poor stability, not easy to save. Temperature range: about 45 DEG ~+100 deg. Mainly used for manufacturing requirements ozone resistance, aging resistance of cable sheath and various protective cover and a protective cover; oil resistance, resistance to chemical corrosion of the hose, adhesive tape and chemical lining; flame resistance of underground mining with rubber products, and a variety of molded products, seals, mat, adhesive and so on.
