The issue of PVC slag
Thread Content
Hello, experts. The PVC polymerization process at my site is stable, but the residue content is too high. Why is that? ? ? ?
I don’t understand what you mean Is it dross or impurities?
It seems to mean that the polymerization is fine, but the product contains a lot of impurities? Impurities have little correlation with polymerization!
Is the black-yellow dot indicator high? Polymerization is fine; then we need to check whether impurities have been introduced during the drying and packaging stages
Is it the number of impurity particles? If the polymerization is stable but the number of impurity particles is high, then the stripping and drying systems used in the polymerization process should be checked.
