Froth process and system for continuous manufacture of polyurethane foam slab-stocks. |
摘要 |
<p>A process and a system for the continuous manufacture of polymeric foams. Reactive chemical components and additives comprising a low boiling blowing agent are mixed under pressure in a mixer (11); the mixture is then frothed before chemical reaction takes place by feeding the mixture through a pressure equalizing and frothing device (13) comprising an elongated pressure-drop zone (17) opening into a frothing cavity (19) having an output aperture (20) to discharge the froth onto a moving substrate (2). <IMAGE></p> |
