Abstract
Inventia se refera la un procedeu de obtinere a silicogelurilor cu mare activitate care porneste de la amestecarea unor solutii de silicat de sodiu si acid acetic, avînd posibilitate de a dirija fabricatia pentru a obtine caracteristicile diferite de adsorbtie-adsorbtie, necesare sortimetului destinat numeroaselor întrebuintari ale acestui produs. Prin modul de alegere a concentratiilor solutiilor de silicat de sodiu si acid acetic si a proportiilor de amestecare întrebuintînd silicat de sodiu cu raportul molar SIO2/Na2O: 2,9...3,4 si densitatea 0,95....1,25 la 20 degree C si acid acetic diluat, avînd densitatea1,005...1,050 la 20 degree C se lucreaza astfel încat pH-ul final sa varieze între 4,0 si 5,8 capacitatea de adsorbtie a vaporilor de benzen, raportata pricentual la cantitatea de silicagel fiind de 10...80%. Introducînd, în tehnologia de preparare o etapa de agitare enrgica, fie în timpul precipitarii, fie înaintea spalarii hidrogenului, se obtine o pulbere de SiO2 cu înalt grad de dispersie. avînd distributia granulometrica 5 nium...250 niu si greutatea specifica 40...400 g/dm3
