Explanation of basic processes of rubber processing

Rubber products - rubber processing method:

The basic process includes basic processes such as molding, mixing, calendering or extrusion, molding and vulcanization. Each process has different requirements for products, and is supported by several auxiliary operations. In order to be able to add various required admixtures to rubber, raw rubber needs to be plasticized first to improve its plasticity; Then, carbon black and various rubber additives are mixed with rubber evenly to form rubber through mixing; The rubber is extruded into a blank with a certain shape; And then it is combined with the textile material (or metal material) that has been calendered and glued to form a semi-finished product; Finally, the semi-finished products with plasticity are made into high elastic final products after vulcanization.

Rubber is a highly elastic polymer. The molecular chain of rubber can be crosslinked. When the crosslinked rubber is deformed by external force, it has the ability to recover quickly, and has good physical and mechanical properties and chemical stability. Rubber is the basic raw material of the rubber industry, which is widely used to manufacture tires, rubber pipes, tapes, cables and other rubber products.
