Has Good Abrasion Resistance, High Elasticity, Breaking Strength
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. The output of synthetic rubber has greatly exceeded that of natural rubber, of which the largest output is styrene-butadiene rubber.
1. During the molding of rubber products, after the large pressure is pressed, the cohesive force of the elastomer cannot be eliminated. When the mold is released from the mold, it often produces extremely unstable shrinkage (the shrinkage rate of rubber varies with different rubber types) , It will take some time to be gentle and stable. Therefore, at the beginning of the design of a rubber product, regardless of the formula or mold, it is necessary to calculate the coordination carefully. If not, the size of the product is likely to be unstable and the quality of the product will be lowered.
2. Rubber is a hot-melt and thermosetting elastomer, and plastic is a hot-melt and cold-set. Due to the different types of sulfur compounds, the temperature range of molding and curing of rubber is also quite different. It can even be affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products need to be appropriately adjusted at any time. If not, there may be differences in product quality.
3. Rubber products are made from rubber raw materials, which are made by mixing mixers with rubber mixers as raw materials. During rubber mixing, formulas are designed according to the characteristics of the required rubber products, and the required product hardness is determined. The product is molded by a rubber flat vulcanizing machine. After the product is formed, the flashing treatment is finally performed to smooth the product surface without burrs.
4. Rubber product aging test belongs to the category of aging test. Rubber aging refers to the phenomenon that during the processing, storage and use of rubber and products, the performance structure changes due to the combined effects of internal and external factors, and the use value is lost. It appears as cracking, stickiness, hardening, softening, chalking, discoloration, mildew, etc.
