Abstract

Un procedimento ed un sistema per la produzione in continuo di schiume polimeriche. I componenti chimici reattivi ed additivi comprendenti un agente di espansione basso bollente, sono miscelati sotto pressione; la miscela viene quindi fatta pre-espandere prima che avvenga la reazione chimica, alimentando la miscela attraverso un dispositivo di pre-espansione e di equalizzazione della pressione comprendente una zona di caduta della pressione che si apre in una cavità di pre-espansione provvista di una apertura di uscita avente un'area di sezione trasversale maggiore di quella della zona di caduta della pressione.
