The rubber sheath is also called wire guard ring, wire guard and grommet. The English name is grommet. It is widely used in the field of wire harness protection for automobiles and various mechanical and electronic equipment. It is dust-proof and shock-absorbing, reduces the direct friction between the wire harness and the moving parts of the machine, and effectively extends its service life. Auto...
There are many kinds of rubber products, but the production process is basically the same. The basic technological process of rubber products with general solid rubber as raw material includes six basic processes: plasticizing, mixing, calendering, pressing, forming and vulcanizing. Of course, raw material preparation, finishing, inspection and packaging and other basic processes are also necessar...
The process of converting plastic rubber to elastic rubber is called vulcanization. It is to add a certain curing agent such as sulfur, curing accelerator and so on into the semi-finished products made of raw rubber. In the vulcanization tank in the specified temperature heating, heat preservation of the raw glue between the linear molecules linked to each other into a three-dimensional network st...
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...
The definition of rubber used in the world is quoted from the national standard definition of the United States as follows: Rubber is a material that can quickly and powerfully recover under large deformation and can be modified (vulcanized). The modified rubber is substantially insoluble in (but soluble in) boiling mixtures of benzene, methyl ethyl ketone, ethanol and toluene. The modified rubber...
