PROCESS AND APPARATUS FOR DEFINED COMMINUTION OF PLYMER GELS

摘要

Apparatus for defined comminution of polymer gels, constructed of a) a static cutting element in the form of screen- shapedly disposed, optionally supported, pretensioned wires, rods, fibers, wovens, stencils or profiles, b) optionally a dynamic cutting element for shortening the gel strands or particles obtained by means of the static cutting unit, in the form of one or more optionally supported, guided and tensioned wires or wovens, and c) a feed unit to feed the polymer gel to the static cutting element in a clamped-in, shape-stable state the feeding being effected batchwise or continuously, and a process for defined comminution of polymer gels.
