Sodium metasilicate yog ib lub ntsev ntawm silicic acid, thiab nws cov molecular mis yuav tsum muab sau raws li Na2SiO3 · nH2O. Sodium metasilicate yog ib tug tsis tshua muaj molecular siv lead ua npaj los ntawm lub cua sov cov tshuaj tiv thaiv ntawm ib tug ntau npuas los luj nrog caustic dej qab zib
Txhais: Sodium metasilicate pentahydrate
CAS no: 6834-92-0
Molecular mis: Na2SiO3 .5H2O
Molecular yuag: M = 122,066
Tsos: dawb siv lead ua hmoov
Sodium metasilicate pentahydrate yog xav alkaline, muaj muaj zog muaj peev xwm tu, buffering thiab softening, counteracting acidic kis, emulsifying roj thiab roj, deflocculating rau inorganic. Nws yuav hloov tau STPP yuav tsum tau siv rau qhov siv thiab ua zoo detergents thiab xeb remover rau hlau, txo tej kev ua qias tuaj, tiv thaiv xeb rau hlau (zinc, txhuas, thiab lwm yam). Yog li ntawd, sodium metasilicate pentahydrate yog dav siv rau qhov siv thiab ua ib tug ntau yam ntawm detergents, siv raws li xeb remover rau hlau, sib tsoo pab rau ceramics, deinking neeg sawv cev rau daim ntawv, dyeing thiab printing koom haum pab kev tshem tawm cov roj nyob rau hauv textile kev lag luam, thiab kuj siv tau raws li lub raw khoom rau flameproofing neeg sawv cev, yas txij nkawm tus neeg saib xyuas, dej tuav tus neeg saib xyuas, thiab lwm yam Siv nyob rau hauv dej kom txhob muaj kab mob, sodium metasilicate pentahydrate yog tau integrate ntau hydrones rau ua kom zoo dua dej haum nyhuv
