Study on characteristics of gas-liquid mass transfer in vinylidene fluoride emulsion polymerization reactor
Zhu You-liang · Chemical engineer · 2005
The measurement method of K value indicating gas-liquid mass transfer effects was carried out.The effects of type, speed of agitator,liquid volume on the K value were investigated, and the optimum condition for vinylidene fluoride emulsion polymerization in the 5L reactor was carried out:liquid volume 3L, agitation speed 700 r·min~(-1) and combining agitator,and so the vinylidene fluoride emulsion polymerization speed 115g PVDF·(L·h)~(-1),latex content 20wt% and sharp particle diameter distribution were then obtained.
