Rubber before vulcanization, there is no cross-linked between molecules, so the lack of good physical and mechanical properties, practical value is not significant. When rubber is added to the vulcanizer, it can be treated by heat treatment or other means to produce cross-linked between rubber molecules, forming a three-dimensional mesh structure, so that its performance is greatly improved, especially the fixed extension stress, elasticity, hardness, tensile strength of rubber and a series of physical and mechanical properties will be greatly improved. The rubber macromolecule reacts with the crosslinking agent sulfur under heating, and the crosslinking becomes the process of the stereoscopic mesh structure. After vulcanization of rubber called vulcanized adhesive.
Vulcanization is the last process in rubber processing, can be trained with practical value of rubber product
