VORRICHTUNGEN UND VERFAHREN ZUR VORBEREITUNG VON POLYMERVERKAPSELTEN GLASFASERTEILCHEN, SOWIE ERZEUGNISSE |
摘要 |
A process and apparatus for making densified glass fiber pellets substantially encapsulated in a polymeric shell from chopped segments of multi-filament glass strand is described. The densified pellets may be advantageously produced by hydrating chopped glass strands and then pelletizing them by tumbling in a rotary drum, densifying the resulting pellets by tumbling in a rotating zig-zag or undulating tube, drying the pellets and encapsulating them in a polymeric composition. The resulting pellets exhibit enhanced degradation resistance during bulk storage and handling. |
