Characteristics Of Rubber Products
1. When the rubber product is molded, the cohesive force of the elastic body can not be eliminated after a large pressure is pressed. When the molding is released from the mold, it often leads to extremely unstable shrinkage (rubber shrinkage rate, due to different types of rubber and different ) It must be after a period of time before it can stabilize. Therefore, when a rubber product is designed, regardless of the formula or the mold, it is necessary to carefully calculate and match. If not, the product size is likely to be unstable and the product quality will be degraded.
2. Rubber is a hot-melt thermosetting elastomer, plastic is a hot-melt cold solid. Due to the different types of rubber in the main body of sulfides, the temperature range of the molding and curing of rubber is quite different. It can even be affected by climate change and indoor temperature and humidity. Therefore, the production conditions of rubber products must be properly adjusted at any time. If not, product quality differences may occur.
3. The rubber product is a rubber compound made from a rubber raw material after being mixed with rubber and used as a raw material. The rubber compound is designed according to the characteristics of the desired rubber product and the required product hardness is set. The product production molding is molded by a rubber plate vulcanizer. After the product is molded, it is processed with flash and the surface of the product is smooth and free of burrs.
4. Aging test of rubber products belongs to the category of aging test. Rubber aging refers to the phenomena that the rubber and its products lose their use value due to the change of performance structure due to the combined action of internal and external factors during processing, storage and use. It is cracked, sticky, hardened, softened, powdered, discolored, moldy, etc.
