Thread Content
If solid alkali is used to dry the monomer, its purpose is ( ) A. To remove moisture from VC B. To remove acidic substances C. To remove iron ions D. To remove hydrochloric acid
Its main function is A: to reduce the water content in the monomer, thereby indirectly decreasing the formation of iron ions
Zeolites specifically designed for PVC stabilizers can replace lead-based stabilizers in PVC products
It mainly removes water; it also eliminates acidic substances. With less acidity, there is naturally less iron ions as well. Hydrochloric acid and similar substances are definitely neutralized, and a slightly alkaline pH is excellent :)
