How are rubber seals classified

Rubber seal strips can be classified according to several methods such as section shape, vulcanization method, use place and purpose, use material, etc. The following is the classification of vulcanization method, specifically as follows:

By vulcanization

1. Discontinuous vulcanization method (after cutting the extruded rubber strip according to a certain length, put it into the vulcanization tank for vulcanization, and put the extruded semi-finished rubber strip into the model for vulcanization);

2. Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, hot air continuous vulcanization method). A. Microwave continuous vulcanization composite seal strip: microwave vulcanization technology is A widely used production technology after the energy crisis in the 1970s. Microwave continuous vulcanization technology can not only produce metal core, solid core rubber and sponge rubber composite rubber strips, and in the energy saving, improve work efficiency and other aspects than other continuous vulcanization device. This technology is recognized by the world as a good process for the production of extruded products. The characteristic of microwave heating is that the heat is directly generated in the heated object, rather than from the external input as usual, which not only generates heat quickly, but also distributes evenly, which is conducive to improving the product quality and greatly reducing the heating time. B. Continuous salt-bath vulcanization seal strip: salt-bath vulcanization adopts the salt-bath system containing nitrite, which causes great pollution to the environment and has been gradually eliminated.

Vulcanization (Tmax: 450°C and Vmax: 60m/s) can also achieve the effect of flame pretreatment, and the safety is greatly improved.

Principle of rubber seal strip

It consists of two parts: sealing and installation. This kind of product mainly USES the flexibility of the lip, cavity, flange and other parts in the body structure and the contact pressure on the surface of the assembled coupling parts (glass, metal parts, etc.) to seal and decorate. Generally used in the range of -50 ~ 70℃.
