Abstract
Il procedimento determina l'impregnazione di manufatti (2) in materiale poroso e comprende:una fase in cui si disidrata il manufatto (2) con azoto ad alta temperatura ed a bassa pressione;una fase nella quale si realizza l'asporto dei gas presenti nei pori del manufatto (2);una fase nella quale si impregnano i pori del manufatto (2) con un impregnante apposito;una fase nella quale azoto a bassa temperatura e con una prefissata pressione fa da battente idraulico per i pori del manufatto (2) riempiti di impregnante;una fase in cui si realizza la polimerizzazione dell'impregnante tramite azoto ad elevata temperatura;una fase nella quale il manufatto (2) viene raffreddato tramite azoto a bassa temperatura.
