Diatomaceous av hmoov zaub mov qib, uas tuaj yeem siv raulim av diatomaceous, roj zaub mov qib thiab lwm yam.
| Lub ntiaj teb diatomaceous yog tsim los ntawm amorphous SiO2, thiab muaj me ntsis Fe2O3, CaO, MgO, Al2O3 thiab cov organic impurities. Lub ntiaj teb diatomaceous feem ntau yog daj daj lossis grey daj, mos, porous thiab lub teeb. Nws feem ntau siv hauv kev lag luam ua cov ntaub ntawv rwb thaiv tsev, cov ntaub ntawv lim dej, cov khoom sau, cov ntaub ntawv abrasive, cov ntaub ntawv iav dej, cov tshuaj decolorizers, cov khoom siv lim dej diatomite, thiab cov neeg nqa khoom catalyst. Tos. Lub ntsiab lus tseem ceeb ntawm lub ntiaj teb diatomaceous ntuj yog SiO2, cov zoo yog dawb, thiab cov ntsiab lus ntawm SiO2 feem ntau tshaj 70%. Monomer diatoms tsis muaj xim thiab pob tshab. Xim ntawm lub ntiaj teb diatomaceous nyob ntawm cov av nplaum minerals thiab cov organic matter. Cov khoom xyaw ntawm lub ntiaj teb diatomaceous los ntawm ntau qhov chaw minerals yog txawv. Cov khoom siv ntxiv xim diatomite muaj cov yam ntxwv ntawm porosity loj, nqus tau zoo, ruaj khov tshuaj lom neeg, hnav tsis kam, tiv taus kub, thiab lwm yam, uas tuaj yeem muab cov txheej nrog cov khoom zoo heev ntawm qhov chaw, sib xws, tuab thiab txhim kho kev nplaum. Vim nws qhov loj ntawm qhov hws, nws tuaj yeem ua rau lub sijhawm qhuav ntawm cov zaj duab xis txheej luv dua. Nws kuj tseem tuaj yeem txo cov resin thiab txo cov nqi. Cov khoom no suav hais tias yog cov khoom siv hmoov matting zoo nrog kev ua tau zoo ntawm tus nqi. Nws tau raug xaiv los ntawm ntau lub tuam txhab tsim khoom loj hauv ntiaj teb thiab siv dav hauv cov av diatom uas yog dej.
