Abstract
Un procedimento e una apparecchiatura per la produzione in continuo di schiume poliuretaniche in blocchi. I componenti chimici reattivi ed additivi, compreso un agente basso-bollente, sono miscelati sotto pressione dopo avere pre-miscelato l'agente di espansione in modo continuo durante la fase di dosaggio volumetrico di uno dei componenti; la miscela viene fatta pre-espandere prima che avvenga la reazione chimica alimentandola attraverso un dispositivo di equalizzazione della pressione e di pre-espansione comprendente una zona di caduta della pressione che si apre in una cavità di pre-espansione avente un'apertura di uscita della miscela di aria maggiore di quella della zona di caduta della pressione.
