Sealing strip is a product that seals a thing so that it is not easy to open, and has the functions of shock absorption, waterproof, sound insulation, heat insulation, dustproof, and fixing. It can be classified according to several methods such as cross-sectional shape, vulcanization method, application location and purpose, and materials used. The following editor of Rubber sealing strip for bus profile introduces classification by vulcanization.
1. Discontinuous vulcanization method (after cutting the extruded rubber strip to a certain length, put it in a vulcanizing tank for vulcanization, and put the semi-finished product of the extruded rubber strip into the model to vulcanize);
2. Continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, hot air continuous vulcanization method, etc.). A. Microwave continuous vulcanization composite sealing strip: The use of microwave continuous vulcanization technology can not only produce composite strips made of metal core, solid core rubber and sponge rubber, but also compared to other continuous vulcanization devices in terms of energy saving and improving work efficiency. superior. The characteristic of microwave heating is that heat is directly generated in the object to be heated, instead of being input from the outside as usual. This not only generates heat quickly, but also distributes uniformly, which is beneficial to improve product quality and greatly shorten the heating time. B. Salt bath continuous vulcanization sealing strip: The salt bath vulcanization adopts a nitrite-containing salt bath system, which pollutes the environment and has been gradually eliminated.
