Abstract

Il gas vettore fornito dal circuito primario (10) della pistola di proiezione (1) comprende tra 1 e 10% d'ossigeno, il resto essendo costituito da azoto, ed è fornito da un'unità di separazione dell'aria (13) ad assorbimento o permeazione. Applicazione in particolare alla formazione di depositi anticorrosione a base di zinco.
