Xingtai oil seal is made to order Small make up to tell you The characteristics of rubber products
1. The rubber molding, after pressure pressing, the cohesion of both by elastomer, cannot be eliminated when molding from, often produce unstable contraction (rubber shrinkage rate, by analysing different difference), after a period of time required, to moderate stability.So when a rubber at the beginning of the design, formula or mould, all need to be careful calculation to cooperate, if not, the size is not stable, easy to produce products products quality is low.
2. Of hot-melt thermoset rubber elastomer, plastic belong to hot-melt cold setting.Rubber by sulfide species subject, different curing temperature range, its shape is also have quite a gap, even because of climate change, the indoor temperature and humidity.Rubber products production conditions, therefore, need do moderate adjustment at any time, if not, may produce products the quality difference.
3. Rubber products is conducted by rubber raw material mixer mixing is made after mixing rubber as raw materials, according to the characteristics of rubber products required in rubber mixing and formula design, and set the required product hardness.Product production molding by rubber vulcanizing press molding.After molding, products and flash processing, product surface treatment is smooth without burr.
4. Rubber aging tests belong to the category of aging test, aging refers to the rubber and rubber products in the processing, storage and use process, due to the combination of internal and external factors causing performance structure change, therefore its use value.Characterized by cracking, tacky, hardening, softening, pulverization, discoloration, mold, etc.
