Abstract
POSTUPAK ZA DOBIJANJE NATRIJUM SILIKATA, amorfni natrijum silikat sa 0,3 do 6 mas. % vode i molskim odnosom izmedju SiO2 i Na2O (1,9 do 2,8) : 1 se dobija iz rastopa stakla sa najmanje 20% mas. čvrstih materija, što se rastopina stakla i natrijumhidroksida sa molskim odnosom SiO2 : NaO (2,0 do 2,8) : 1 tretira na temperaturi od 180В°C-240В°C i pritisku od 10-30 v. Tu rastopinu izložimo u zoni sušenja sa vazduhom na temperaturi 200-300В°C 10-20s, zatim na temperaturi 90-130В°C pri čemu nastaje praškasti amorfni natrijumsilikat sa sadržajem vode (dodate pri žarenju na 700В°C) 15 do 23 mas.% i nasipnom masom od 300 g/l. Praškasti natrijev silikat se dalje tretira u koso postavljenoj aparaturi za pomeranje čvrstih materija tj. u rotacionoj cevnoj peći kroz koju prolaze dimni gasovi na temperaturi u 250-500 В°C u vremenu od 1. 60 min. Temperatura spoljneg zida rotacione peći je oko 60В°C. Dobijeni amorfni natrijum silikat se drobi pomoću mehaničke drobilice na zrna od 0,1-12 mm.
