METHOD AND APPARATUS FOR PREPARING OF HIGH MACROMOLECULE LATEX RESIN POWDER

摘要

The present invention relates to a method for producing a polymer latex resin powder, in particular a large amount of the rubber increases tack spray drying the polymer latex is a polymer latex resin powder according to the method for recovering a powder. ; If the rubber content is high polymer latex is recovered by spray drying the powder deposit is generated in a large amount, and K King, there is a problem that characteristic is deteriorated. The invention In order to solve this problem, in the spray drying process of the polymer latex resin powder was conveyed a portion of the waste gas was used in the air film forming apparatus. The spray-drying method may minimize the formation of deposits without increased energy cost of using the air film forming apparatus, increasing the coating efficiency of the additive to reduce the loss of the additives improve the stability in the post-processing step, such as dust collectors also release of the additive burden on the air pollution can also be reduced by. ; In addition, a spray drying method is proposed in the present invention is excellent in caking characteristics and flowability is excellent in the polymer latex resin powder relative to the polymer powder prepared by the conventional spray drying methods at the same additive input is a technique that can be produced.
