Problems solved by technology

[0012] At present, domestic manufacturers of chlorinated polyethylene all use a single set of equipment for the production of acid phase suspension method and water phase suspension method. The acid phase suspension method can recycle hydrochloric acid. low, it can only be treated as wastewater, and the price of hydrochloric acid will fluctuate with market conditions. When the market is in a downturn, the recovery and utilization of hydrochloric acid by the acid phase suspension method cannot produce sufficient economic value; when the price of hydrochloric acid is high , the aqueous phase suspension method directly treats dilute acid as wastewater, which is also a waste of resources
