Changshu da plastic products factory introduction of UPVC drainage pipe smoothly three kinds of common problems

UPVC drainage pipe plastic pipe industry in our country is too big to total yields around 50%, is the most widely used, application early, most familiar plastic tubing.
We found in the test, however, there are many of UPVC drainage pipe.
This is because the PVC resin in terms of performance is poorer, plus the processing scope is narrow, UPVC drainage pipe forming conditions and extremely GouKe, so for UPVC drainage pipe production enterprises, to find the best additives (
Such as stabilizing agent, modification agent, lubricant, filler, etc. )
, the optimal formulation and the reasonable technology is the premise to guarantee the quality of plastic tubing.
Changshu da plastic products factory introduction of UPVC drainage pipe smoothly below three kinds of common problems.
1, poor impact resistance. According to GB/T5836. 1 - — For several years, the 92 standard testing drop weight impact test, found that a passing rate is only less than 50%, UPVC drainage pipe products and even impact is all broken 10 times.
2, poor tensile strength and toughness. Good UPVC drainage pipe its tensile strength curve should have obvious yield, elongation, and poor plastic tubing is often characterized by brittle, low elongation and easy to break.
3, softening temperature is low, easy to deformation when it is heated. Performance on the test performance, vicat softening temperature is low ( Less than 79) , some manufacturers to increase the softening temperature of the plastic pipe material, simply increase the amount of filler in plastic pipe material ingredient, do indeed can improve the plastic pipe material softening temperature, but it is a plastic pipe other properties, especially the impact resistance, tensile strength and toughness is greatly reduced, thus to improve the softening temperature, and not the other performance, reduce or rarely should choose additives in plastic pipe material, ratio of raw materials, production process, fluctuate and production machinery, can not be lightly change formula.
