Inorganic silica gel yog cov khoom siv adsorption zoo heev, uas feem ntau yog npaj los ntawm kev ua haujlwm ntawm sodium silicate thiab sulfuric acid thiab ua raws li cov txheej txheem tom qab kho xws li kev laus thiab cov kua qaub foaming. Silica gel yog cov tshuaj amorphous, thiab nws cov tshuaj formula yog mSiO2. nH 2 o. Nws yog insoluble nyob rau hauv dej thiab tej kuab tshuaj, non-toxic, tasteless, tshuaj ruaj khov, thiab tsis hnov mob nrog tej yam tshuaj tshwj tsis yog muaj zog alkalis thiab hydrofluoric acid. Ntau hom silica gel tsim cov qauv microporous sib txawv vim lawv txoj kev tsim khoom sib txawv. Cov tshuaj lom neeg muaj pes tsawg leeg thiab cov qauv ntawm lub cev ntawm silica gel txiav txim siab tias nws muaj ntau yam ntxwv uas lwm yam khoom zoo sib xws yog qhov nyuaj los hloov: kev ua haujlwm siab adsorption, zoo thermal stability, ruaj khov khoom, siab mechanical zog, thiab lwm yam., siv hauv tsev ua desiccant, av noo Regulator, deodorant, thiab lwm yam; industrially siv los ua roj hydrocarbon decolorizer, catalyst cab kuj, siab viav vias adsorbent, thiab lwm yam .; Kev sib cais thiab purification tus neeg saib xyuas rau kev lag luam tshuaj zoo, npias stabilizer, xim thickener, tshuaj txhuam hniav txhuam tus neeg sawv cev, matting tus neeg saib xyuas, thiab lwm yam.
Raws li qhov loj ntawm nws qhov pore loj, silica gel tau muab faib ua: macroporous silica gel, coarse pore silica gel, hom B silica gel, thiab nplua pore silica gel. Vim qhov txawv ntawm qhov pore qauv, lawv cov khoom adsorption muaj lawv tus kheej yam ntxwv. Coarse-pored silica gel muaj peev xwm adsorption ntau dua thaum cov txheeb ze av noo siab, thaum nplua-pored silica gel muaj peev xwm adsorption ntau dua li coarse-pored silica gel thaum cov txheeb ze av qis. Hom B silica gel muaj qhov pore qauv ntawm ntxhib thiab nplua. Nyob nruab nrab ntawm lub pores, tus nqi ntawm adsorption kuj yog nruab nrab ntawm cov ntxhib thiab nplua pores.
Inorganic silica gel tuaj yeem muab faib ua npias silica gel, siab viav vias adsorption silica gel, kho mob silica gel, hloov xim silica gel, silica gel desiccant, silica gel qhib tus neeg sawv cev, thiab tshuaj txhuam hniav silica gel raws li nws siv.
