Vulcanized elastic rubber is called vulcanized rubber, also known as soft rubber, commonly known as "rubber". Vulcanization is one of the most important technological processes for rubber processing. All kinds of rubber products must be vulcanized to obtain the ideal performance. Unvulcanized rubber in use is not of use value. But insufficient sulfur or curing time is not enough to make...
With the increase of room temperature vulcanization materials and the appearance of high temperature vulcanization, the vulcanization temperature tends to two extremes. From the improvement of curing efficiency, it should be considered that the higher the curing temperature, the better. But in fact we can not infinitely increase the curing temperature. Rubber is a high polymer, high temperature wi...
Silicone rubber polymer molecule is composed of Si-O bond into a chain structure, its main composition is high molar mass linear polysiloxane. Because of the Si-O-Si bond is the basic type, what the silicon atom connects is methyl. There is very small amount of unsaturated side chain groups and small molecular inter-atomic forces, and molecular spiraling structure with methyl arranged outwards can...
No matter what rubber products, they have to go through the two processes of mixing and vulcanization. For many rubber products, such as rubber hose, rubber tape, tires, etc., it is necessary to go through the two processes of calendering and pressing. For the raw glue with high Mooney viscosity, plastication is needed. Therefore, the most basic and important processing process in rubber pro...
The rubber industry has more than 100 years of development history in the world, rubber has been widely used in transportation, construction, electronics, aerospace, petroleum chemical industry, agriculture, machinery, military, water conservancy industry and information industry, people's life and other aspects. It is of great importance to develop the rubber industry. The biggest use of rubber i...
Rubber compound is a process of combining raw rubber and compounding agent according to the performance requirements of products,considering factors such as processing technology performance and cost.The general compound system includes raw glue, curing system, reinforcing system, protection system, plasticizing system, etc.. Sometimes it also includes some other special systems such as flame reta...
