How to clean rubber products?
Rubber products aging test belongs to the category of aging test, rubber aging refers to rubber and products in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors caused by the performance of the structure change, then the loss of use value phenomenon. They are crazing, sticking, hardening, softening, powdering, discoloration, mildew, etc..
Rubber products are made of rubber raw materials and made from mixing rubber and mixed rubber as raw materials. When the rubber is mixed, the formula is designed according to the characteristics of the required rubber products, and the hardness of the products is determined. The product is made and molded by rubber flat vulcanizing machine. Finally, the product is processed by flying edge, and the surface of the product is treated smoothly without burrs.
Rubber is elastic hot melt thermosetting body, plastic is hot cold setting. Rubber due to different types of sulfide species, its molding and curing temperature range is also a considerable gap, and even can be affected by climate change, indoor temperature and humidity affected. Therefore, the production conditions of rubber products need to be adjusted at any time. If not, the quality of the products may be different.
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.
