Silica khoom rau cov khoom siv rwb thaiv tsev
Silica yog cov khoom siv dav siv hauv kev tsim cov ntaub ntawv rwb thaiv tsev vim nws cov thermal rwb thaiv tsev zoo heev. Lub precipitated silica uas ua los ntawm cov txheej txheem sedimentation yog tshwj xeeb tshaj yog muaj txiaj ntsig rau nws lub peev xwm nqus roj thiab nws cov ntsiab lus dej siab.
Thaum siv los ua ib qho adsorbent, precipitated silica muaj cov roj nqus dej siab, uas ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv cov roj nchuav thiab lwm yam kev siv uas cov roj yuav tsum tau nqus thiab ntim. Tsis tas li ntawd, cov ntsiab lus dej siab ntawm cov silica precipitated ua rau nws ua haujlwm kom qhuav, muaj peev xwm tshem tawm cov dej noo los ntawm ntau yam ntaub ntawv thiab qhov chaw.
Cov txheej txheem sedimentation siv los tsim cov silica precipitated muaj kev sib ntxiv ntawm silica-nplua nuj tov rau cov kua qaub, uas ua rau cov silica hais los nag. Cov khoom uas tau tshwm sim yog cov hmoov dawb zoo uas yog cov ntshiab huv heev thiab tsis muaj cov impurities lossis cov kab mob sib kis. Lub precipitated silica ua los ntawm txoj kev no yog heev npaum, muab zoo heev thermal rwb thaiv tsev thiab nqus cov khoom.
Ntxiv nrog rau kev siv cov ntaub ntawv rwb thaiv tsev, precipitated silica yog siv dav hauv ntau daim ntawv thov, suav nrog tshuaj, tshuaj pleev ib ce, thiab khoom noj khoom haus. Nws versatility thiab kev ua tau zoo ua rau nws nrhiav tau cov khoom siv uas tau siv dav hauv ntau lub lag luam thoob ntiaj teb.
