Dawb Silica Gel
Silica gel desiccant yog ib yam khoom siv adsorption uas muaj zog heev, feem ntau yog ua los ntawm kev sib xyaw sodium silicate nrog sulfuric acid, kev laus, kua qaub npuas thiab ntau yam txheej txheem tom qab kho. Silica gel yog ib yam khoom amorphous, thiab nws cov mis tshuaj yog mSiO2. nH2O. Nws tsis yaj hauv dej thiab lwm yam kuab tshuaj, tsis muaj tshuaj lom thiab tsis qab, nrog cov khoom siv tshuaj ruaj khov, thiab tsis sib xyaw nrog lwm yam khoom tsuas yog lub hauv paus muaj zog thiab hydrofluoric acid. Cov tshuaj lom neeg thiab cov qauv ntawm silica gel txiav txim siab tias nws muaj cov yam ntxwv uas ntau lwm yam khoom zoo sib xws nyuaj rau hloov. Silica gel desiccant muaj kev ua tau zoo adsorption, zoo thermal stability, ruaj khov tshuaj lom neeg, muaj zog kho tshuab siab, thiab lwm yam.
