Quality and energy-saving technology for producing high-grade PVC by calcium carbide method
Through the research on the PVC polymerization process by calcium carbide method and the heat balance of the entire plant,it is pointed out that according to the quality characteristics of the monomer of the calcium carbide process,problems such as a large number of impurities,apparent density,particle size distribution,large fluctuations in viscosity number,accompanied by high steam consumption,volatile mat-ter being prone to disqualification,excessive sieve residue,and energy loss due to device diversification are prone to occur in the production of large-scale polymerization kettles.Through in-depth research,reason-able solutions are given.
