How to identify the tire rubber is raw or cooked
Rubber is a kind of polymer material with high elasticity, is the parent material manufacturing of rubber products, generally refers to the rubber unvulcanized. A nearly neutral liquid produced by a rubber tree and added with 0.05%~0.1% ammonia water to make latex (for a short period of time). Most of the latex need processed dry glue, all kinds of natural rubber is often said.
All use glue tire manufacturing, rubber is the parent material of rubber products, rarely used directly.
Rubber molding, after pressing, the elastic body is within the cohesion can not be eliminated, the molding die, often have a very unstable contraction (rubber shrinkage due to rubber vary), required after a period of time, and can be stable. Therefore, when a rubber product design at the beginning, regardless of formula or mold, it is necessary to carefully calculate the coordination, if not, it is easy to produce product size instability, resulting in lower quality products.
