TH35096EX - Process for the preparation of new highly solid anhydrous polymer compositions - Google Patents

Abstract

Revealed the use of falling film evaporation. And concentrate equipment Such as separation by centrifuge To dehydrate and concentrate polymer emulsions or chaste pensions. Water-in-oil In the right way is To do dehydration to Water-in-oil polymer composition contains approximately 25% of the countable polymers. In the falling film evaporator To the evaporator concentration of approximately 5.0% of the water, the concentrate is then directed into a separation device such as a splitter in the filter to separate the oil to produce a polymer-containing composition. And emulsifying elements Servant In - the oil contained approximately 60% by weight, the solid polymer. May choose to continue raffinate from This centrifuge in the second separation device. To separate poly More solid mor Which may bring this oily raffinate Reusable Which should make the polymer composition concentrated This is stable with a steric stabilizer. To produce produce The liquid can flow freely.
