Abstract

In un procedimento noto per fabbricare tubi in plastica, in cui una resina liquida, un catalizzatore nonché sabbia e fibre di vetro vengono introdotte in un tamburo di centrifugazione e dove mediante indurimento del materiale plastico si forma il tubo, era finora usuale avviare o promuovere la fase di indurimento o solidificazione insufflando aria riscaldata nel tamburo di centrifugazione. Pertanto l'aria che esce dall'interno del tamburo contiene vapori di solvente, che inquinano l'ambiente. Il procedimento migliorato consiste quindi nel fatto che il calore necessario per iniziare la fase di solidificazione non più alimentato dall'interno mediante aria calda, bensì mediante acqua calda spruzzata esternamente sul tamburo di centrifugazione, acqua che viene inviata in un circuito dell'acqua calda ed in questo, dopo che ha avuto inizio l'indurimento esotermico, si riscalda di nuovo almeno alla temperatura originaria e in tal modo asporta calore di processo. Per raffreddare ulteriormente serve un circuito dell'acqua fredda, che si può inserire a piacere per bagnare il tamburo di centrifugazione.
