Compared with the other rubber vulcanization technology such as microwave vulcanization, the salt bath vulcanization is characteristic prominently, because it has excellent treatment quality, very high vulcanization speed and wide applicability (enabling to vulcanize color rubber), and furthermore:

Since vulcanization salt bath has excellent heat transfer performance, the whole section of rubber seal strip can be vulcanized completely and evenly;

In vulcanization, the rubber sealing strip dipped in high-density salt bath bears even pressure and undergoes a greatly small vulcanization deformation;

Salt bath restricts the formation of low vulcanization areas on the rubber surface, so the rubber treated by salt bath vulcanization has good mechanical property;

The surface of the rubber by salt bath vulcanization is of few micropores and smooth;

No influence from vulcanization is applied to the reinforcing material (if any) in rubber sealing strips.

The section of rubber sealing strip can be simpler and thinner;

At the same vulcanization speed, the device of salt bath vulcanization system is shorter.

As a new technique developed rapidly, rubber microwave vulcanization production line is advantaged in high efficiency, low occupation, clean products, etc., suitable for various products with complicated dimensions and sections, available for the sealing strips of the doors and windows of automobiles, containers and buildings, air conditioning rubbers, etc.
