Production process and raw material of rubber?
The basic process of rubber products:1, plasticization2, mixing3, calendering4. Press out5, forming6, vulcanization
Raw material: rubber, rubber with various agents, as well as the fiber and metal skeleton materials.
Process selection: the tensile strength is the limit ability to characterize products can resist tensile failure. The main factors affecting the tensile strength of rubber are: the main valence bond, intermolecular force and polymer chain flexibility of macromolecular chains. The relationship between tensile strength and rubber structure: a large force between molecules, such as polar and rigid groups; the molecular weight increases, increasing the fan Edward force, the chain segment is not easy to slip, the equivalent of molecules formed between physical crosslinking points with the molecular weight increased, the tensile strength increased to a certain extent reached equilibrium; microstructure the molecular structure, such as the effect of cis - and trans structure; crystallization and orientation
Raw materials: all kinds of rubber, rubber compounding agent, as well as the fiber and metal skeleton materials.
