The effect of the sulfide process on the flattening of the insulated conductor

In the process of production of rubber insulated cable, the effect of the insulation wire core flattening is analyzed from the Angle of vulcanization process.

Vulcanization process quality directly decides the degree of cure of insulated wire core (degree of cross-linking), molecular chain of rubber under the effect of stress for a long time, the relative displacement of the molecular chain will happen to produce stress relaxation, stress after removal of rubber molecules deformation ability to reduce or even lost, produce permanent deformation. The high degree of crosslinking reduces the displacement and stress of the rubber molecules, and maintains high recovery ability and reduces permanent deformation.

With the increase of vulcanization time, the degree of vulcanization is deepened, the compression permanent deformation becomes smaller, the degree of vulcanization is sufficient, the compression of permanent deformation is minimal; This is because, with the deepening of the sulfide, the crosslinking is gaining in the ascendant, the rubber is hard, and the compression is small.

Steam curing insulation wire core, the precise control of rubber vulcanization time, make good vulcanization process, the insulated wire core is one of the important factors of roundness.
