橡胶生产工艺简介（Brief introduction of rubber production process）

橡胶生产工艺简介（Brief introduction of rubber production process） Rubber, production process, brief introduction, share 1 Summary The main raw material is rubber, rubber products with various agents, as well as the fiber and metal skeleton material, the basic production process of rubber products including plastication, mixing, calendering, extrusion, molding, curing 6 basic processes. The processing process of rubber is mainly to solve the process of plastic and elastic contradictions, through various means of processing, the elastic rubber has become the plastic rubber, adding various in the preparation of semi-finished products, and then through the vulcanization is has semi-finished plastic and rubber products into high elasticity and good mechanical performance the. 2 rubber processing technology 2.1 plastic process Rubber mastication is force, heat, oxygen or adding some chemical agents and other methods should be made by mechanical, rubber transition from elastic state for strengthening soft, easy processing of plastic process. Rubber mastication is designed to reduce its elasticity, increase the plasticity, and obtain adequate liquidity, mixing, extrusion, molding, sub diffraction, and glue manufacturing sponge, curing and other manufacturing process to meet the requirements of. Mastering proper plasticity of plastic is essential to the processing of rubber products and the quality of finished products. The plastic degree should be reduced as much as possible in order to meet the requirements of processing technology. With the appearance of constant viscosity rubber and low viscosity rubber, some rubber is no longer need to be refined and mixed directly. In the rubber industry, the most commonly used methods of refining are mechanical plasticization and chemical plasticization. The main equipments used in mechanical plastics are open rubber mixer, closed rubber mixer and screw extruder. Chemical plasticization is a method to increase the effect of plasticization by
