Description
Technical field
The present invention relates to a kind of CABLE MATERIALS, more particularly to a kind of manufacture method of polyvinyl chloride cable material.
Background technology
Polrvinyl chloride (pvc) is a kind of polymeric material (or resin), and it is the monomer chloroethene by molecular formula for ch2=chcl
Alkene (vcm) multiple stacking forms.In addition to chloride, pvc and polyethylene have identical structure, and chlorine accounts for simple polymerisation tree in pvc
The 57% of fat, 3 5% chlorine are derived from the electrolysis of chloral potassium.Pure pvc is granular material, and mechanical hardness is high, extraordinary weather protection
Change, the anti-chemical physical performance of waterproof and be electrically insulating material, but pvc is relatively unstable to light and heat, heating and ultraviolet light
Result in chlorine to lose in the hydrogen chloride (hcl), this can by plus stabilizer avoid, stabilizer generally by slaine such as lead,
Barium, calcium, cadmium or organo-tin compound composition.Pvc has good physics, chemistry, the performance such as electrically, twentieth century three or four because of it
The ten's abroad began to the insulant using soft pvc as electric wire, and the development and application of China's PVC cable material start from last century
The fifties.The popularization of the raising with pvc resin, plasticizer and commercial auxiliaries production capacity and new varieties and application and development,
