METHOD AND APPARATUS FOR DETERMINED BREAKING OF GEL-POLYMERISATUMS

摘要

The assembly to reduce polymerized gels to particles has a static cutter (3) where the gels are forced through, as a grid of wires, rods, fibers, woven fabrics, matrices or profiles of metal, glass, carbon, ceramics, cellulose or boron. A dynamic cutter (4) chops the strands forced through the static grid, using one or more moving tensed wired or fabrics. The feed unit (2) has a press die (1) to force the plastics gels through the static grid continuously or intermittently. The chopped particles have the shape of a cube or a prism or a cylinder, with a height:diameter ratio of 1:1.
