Ntim Khoom thiab Khaws Cia
Silicon dioxide raug ntim rau hauv cov thawv kaw kom ntseeg tau tias nws tseem qhuav thiab tsis muaj kuab paug thaum lub sijhawm thauj mus los thiab khaws cia. Nws yuav tsum khaws cia rau hauv qhov chaw txias, qhuav, thiab muaj cua nkag zoo, deb ntawm cov tshuaj corrosive muaj zog xws li acids thiab alkalis. Thaum lub sijhawm khaws cia, yuav tsum tau them sai sai rau kev tiv thaiv dej noo thiab kev zam kom tsis txhob kub dhau kom ntseeg tau tias cov khoom ruaj khov thiab muaj kev nyab xeeb.
