( Industry news] Must solve the quality problem of the common cable material chenyl P wire and cable industry is heavy industry light '' material industry, the cost of materials of the product cost % ~ %. Therefore, choose performance - Price reasonable materials, ensure the quality of the materials into the factory, is to reduce the product cost, one of the important ways to enhance the competitiveness of enterprises. Material quality problems as follows, : material supplier, please cooperate with improvement. Copper rod: made of recycled miscellaneous copper, surface oxidation discoloration, tension is not enough, not roundness, etc. 。 PVC plastic: impurities, thermal weightlessness is unqualified, extrusion layer porosity, plasticizing hard, color is not straight, etc. 。 Described. properties of insulation material: resistance to scorch time is short, easy to early crosslinking, etc. 。 Silane crosslinking material: bad extrusion temperature control, poor thermal stretching, rough surface, etc. 。 Copper strip thickness unevenness, oxidation, discoloration, not enough tension, falbala, softening and partial hard, short head, in bad place, film, or zinc layer falls off, etc. 。 Wire diameter is larger, insufficient shedding, galvanized zinc layer, short head, tension is not enough, and so on. 。 PP filled rope: poor material, diameter of uneven, in bad place a knot in one's, etc. 。 PE filling: hard, easy to break, radian is wrong, and so on. 。 Non-woven fabric: the thickness of the actual goods when wrong version, not enough tension, the width of the uneven and so on. 。 PVC tape: partial thick, not enough tension, short head, uneven thickness, etc. 。 Fire-resistant mica tape: layering, not enough tension, sticky, reel wrinkling, etc. 。 Non-alkali rock cotton rope: the thickness is uneven, not enough tension, joint, easy to fall more powder, etc. 。 Glass ribbon: thick, reel off raw silk from cocoons, density is small, mixed organic fiber, easy tear etc. 。 Halogen-free flame retardant glue coating with: easy to break, with plate wrinkling, reel off raw silk from cocoons, flame retardancy, smoke, etc. 。 Heat shrinkable cap seal: size is not allowed, poor memory, long firing shrinkage, strength etc. Some materials manufacturers one-sided pursuit of cost reduction, or blindly cater to the user demand requirements, churning out, cut corners, the material quality not use requirement, for wire and cable manufacturers caused direct economic losses, so return often happen, evasive, refused to pay, make both unhappy. The right attitude should be, the supply and demand both sides talks things over consistent, discuss both ways to reduce the cost of materials and shall not affect the product quality, mutual benefit, common development
