Introduction of rubber products

　　1. When rubber products are formed, they are pressed by large pressure, because the cohesion of the elastomer can not be eliminated, and often produce extremely unstable shrinkage (the shrinkage rate of rubber is different due to different types of rubber), which must be gentle and stable after a period of time. Therefore, at the beginning of the design of a rubber product, regardless of the formula or mold, it is necessary to carefully calculate and cooperate, if not, it is easy to produce product size instability, resulting in low product quality.

　　2. Rubber is a hot-soluble thermosetting elastomer, and plastics are hot-soluble cold solid. Due to the different types of sulfide, the temperature range of rubber molding and curing is also quite different, and it can even be affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be adjusted moderately at any time, if not, it may produce differences in product quality.

　　3. Rubber products are made of rubber raw materials after mixing the rubber mixer as raw materials, in the rubber mixing according to the characteristics of the required rubber products and design the formula, and set the required product hardness. The product is molded by rubber plate vulcanizing machine. After forming the product, the final flash treatment is carried out to smooth the surface treatment of the product without burrs.

　　(4) Rubber products aging test belongs to the category of aging test, rubber aging refers to the rubber and products in the process of processing, storage and use, due to the comprehensive effect of internal and external factors caused by the change of performance structure, and then the loss of use value. It is cracked, sticky, hardened, softened, powdered, discolored, mildew and so on.
