method and device for getting rid of treibmittelgasen from kunsstoffschäumen

摘要

Blowing agent gases are expelled from plastic foams by first of all coarsely precomminuting plastic foam to the extent necessary within a closed plant and subsequently transferring it into a compacting plant, in which the foam is worked and pressed with the aid of a reciprocating ram, so that it emerges as a gas-free compact. Blowing gas released during the process sequence is removed by suction and recovered in the liquid state.
