POST-PROCESSING OF POLYMERIC GRANULES

摘要

FIELD: chemistry. ^ SUBSTANCE: method involves the supply of a stream of water with poly-olefin granules in a column, cooling the poly-olefin granules in the process of their flow up the column counter-flow downward flowing cooling water with the speed of between 0.5 to 4 cm/sec and collecting cooled granules from the upper part of the column. The cooling water has a density higher than the density of the specified poly-olefin; in this case the speed of the cooling water is kept constant. Collecting of the granules is carried out after they have been in the column from 2 to 20 minutes. ^ EFFECT: effective and homogenous cooling of a large amount of polymeric granules, noticeably reduces the tendency of granules to agglomeration. ^ 21 cl, 1 dwg, 3 ex
