Abstract

Inventia consta în producerea unor materiale refractare termoizolatoare permeabile la gaze si fluide la temperaturi cuprinse între -250 si 1000gradeC. Produsul este rezistent la actiunea acizilor, bazelor, zgurilor topite, sticlelor topite, metalelor topite, a produselor petroliere, precum si a gazelor în intervalul de temperaturi mentionat. Se procedeaza prin îmbinarea unui burete cu structura controlata de pori cu obarbotina de materiale refractare asociate corespunzator dupa care se procedeaza la eliminarea excesului refractar, la uscarea produsului si la calcinarea sa. Eventual, pentru filtrarea materialelor topite se procedeaza la o impregnare suplimntara.
