Rubber machine|Basic characteristics of rubber products
Rubber products refer to the activities of producing various rubber products using natural and synthetic rubber as raw materials, and also include rubber products reproduced from waste rubber.

Basic characteristics of rubber products
⒈When the rubber product is molded, after high pressure suppression, the cohesive force of the elastic body cannot be eliminated, and it often produces extremely unstable shrinkage when it is molded out of the mold (the shrinkage rate of rubber varies depending on the type of rubber) , After a period of time, it can be slow and stable. Therefore, at the beginning of the design of a rubber product, regardless of the formula or mold, it is necessary to carefully calculate the fit. If not, the product size is likely to be unstable and the product quality is low.
⒉Rubber is a hot-melt thermosetting elastomer, while plastic is hot-melt and cold-solid. Due to the different types of sulfide, the temperature range of the molding and curing of rubber is also quite different, and it may even be affected by climate changes and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be adjusted appropriately at any time. If not, the quality of the products may vary.
3. Rubber products are the mixed rubber made from rubber raw materials after internal mixer mixing as raw materials. The formula is designed according to the characteristics of the required rubber products during rubber mixing, and the required product hardness is determined. The product is made and molded by a rubber plate vulcanizing machine. After the product is formed, the flashing treatment is carried out to make the surface of the product smooth and free of burrs.
4. Rubber product aging test belongs to the category of microspectral analysis aging test. Rubber aging refers to the phenomenon that the performance structure of rubber and products changes due to the combined effects of internal and external factors during processing, storage and use, and thus loses use value. It shows cracking, stickiness, hardening, softening, chalking, discoloration, mildew, etc.
