Silica rau tshuaj tua kab thiab chiv
Khoom Taw Qhia:
Khoom npe: Silicon Dioxide
CAS. TSIS TAU.: 7631-86-9
Txoj kev nag lossis daus feem ntau yog siv los ua cov pa roj carbon dub, ib hom amorphous, hmoov zoo uas muaj ntau yam kev siv hauv cov khoom siv tshuaj lom neeg xws li tshuaj tua kab thiab cov chiv zoo. Cov pa roj carbon dub tuaj yeem siv los ua cov khoom thauj lossis diluent, thiab cov khoom sib cais kom muaj kev ncua, tshwj xeeb tshaj yog thaum siv hauv dej dispersible granules (WDG). Cov lus qhia siv tus nqi yog nyob ib ncig ntawm 10 feem pua, thiab nws tuaj yeem tswj tau lub sijhawm ntev vim nws qhov chaw siab heev uas muab cov adsorption muaj zog, zoo heev affinity, thiab tshuaj stability.
Lub peev xwm raug tshem tawm siab ntawm cov pa roj carbon dub kom ntseeg tau tias nws tseem raug tshem tawm hauv kev tsim, txawm tias nyob rau hauv cov huab cua nyuaj xws li los nag, ntxhua, thiab cua sov. Nws cov khoom zoo kawg nkaus ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv ua liaj ua teb uas yuav tsum tau muaj kev ruaj ntseg thiab kev ncua hauv kev tsim.
Dawb carbon dub kuj pab txhim kho kev ua tau zoo ntawm cov tshuaj tua kab thiab chiv los ntawm kev txhim kho lawv cov kev nkag mus, adhesion, thiab kev sib kis muaj peev xwm, uas tuaj yeem ua kom lawv cov txiaj ntsig zoo tshaj plaws hauv kev kho cov kab mob qoob loo, kab tsuag, thiab txhawb kev loj hlob. Tsis tas li ntawd, nws qhov nruab nrab pH, tsis tshua muaj abrasiveness, thiab kev nyab xeeb zoo profile ua rau nws xav tau rau kev ua liaj ua teb.
