Anhui PVC pipe supplier, how accurate Anhui buy PVC drain, especially the nature of the flow fairly poor Anhui PVC drain, PVC melt temperature during processing is a very tightly closed variable process parameters, the process is very narrow range, if This parametric inappropriate material will cause the problem of decomposition. Until now the most common color of white PVC drain, the color is creamy white color and the average, in the outer wall are relatively Guangliu and feel somewhat tough as well, and compare times UPVC drainage white color is not white, is a little hair yellow, and hard, and some uneven color, some outer Guangliu particular, while the inner wall does not seem delicate, sometimes acupuncture or perforations; Anhui PVC drain toughness is crucial indicators. Great toughness pipe, when we will be sawn into strips, trying to break 180, if a discount on the break, explaining understand poor toughness, brittleness; if hard to pull down, explaining understand toughness, and the more time off the ability to pull down demand strenuous pipe, better strength, toughness ordinary bad. Especially the high molecular weight PVC material more difficult to process, because the general use are small molecular weight PVC material.
