Reasons for a sharp increase in pressure during the PVC polymerization process without an increase in temperature: ( ) A. Excessive amount of water added B. Impure discharge from the pump C. Too high a filling factor D. Uneven dispersion of the mixture. Answer: A, B, C
A. Excessive water injection volume B. Impure discharge from the pump C. Too high a filling factor
Reasons for a sharp increase in pressure without an increase in temperature during the VC polymerization process: (A) A, excessive amount of water being injected; B, impurities in the product discharged by the pump; C, too high a packing factor; D, uneven dispersion of the system
Reasons for the sharp increase in pressure while the temperature does not rise during the PVC polymerization process: (ABC)
Choose c; the filling factor is too large. We call it Manfu here.
A, B, C. Excessive water injection, impure discharge from the pump, too high filler coefficient
