Technical Field

The utility model relates to an inner tube of a tyre vulcanizes technical field, in particular to inner tube of a tyre vulcanizes interior pressure sealing washer fort that admits air.

Background

Vulcanization is a process in which rubber macromolecules react with a cross-linking agent, namely sulfur, under heating, and the rubber macromolecules are cross-linked into a three-dimensional network structure. The vulcanized rubber is called vulcanized rubber. Vulcanization is the last step in rubber processing, and a shaped rubber product with practical value can be obtained. The density of sulfur crosslinks in the network of rubber determines the degree of vulcanization of the rubber. The latter is judged in the process practice as a change in the macroscopic physical-mechanical properties of the rubber compound or in the rubber viscosity. The rubber has plasticity before vulcanization treatment, and after vulcanization treatment, the rubber has elasticity due to the formation of a net structure, so that the rubber becomes a production and living material with important value, and the traditional inner tube vulcanization is easy to cause steam outflow and steam leakage phenomenon in an inner pressure gun platform, so that steam energy waste is caused.
