Diatomite yog ib hom pob zeb siliceous. Diatomite muaj cov amorphous SiO2 thiab muaj me ntsis Fe2O3, CaO, MgO, Al2O3 thiab cov organic impurities. Qhov zoo ntawm kev siv diatomite: 1: pH nruab nrab, tsis muaj tshuaj lom, kev ua haujlwm zoo ntawm kev ncua, kev ua haujlwm adsorption muaj zog, qhov hnyav me me, 2: diatomite yuav tsum siv ua cov khoom ntxiv rau hauv cement, 3: kev nthuav dav zoo heev, lub zog cuam tshuam siab, lub zog tensile, lub zog tsim kua muag, lub teeb thiab mos sab hauv sib tsoo, lub zog compressive zoo, thiab lwm yam. Qhov zoo ntawm kev siv diatomite: pH nruab nrab, tsis muaj tshuaj lom, qhov zoo 120 txog 1200 mesh, Nws yog lub teeb thiab mos, thiab yog cov khoom zoo hauv cov xim. Kev lag luam pub: cov khoom ntxiv rau npua, qaib, os, geese, ntses, noog, cov khoom hauv dej thiab lwm yam pub. Daim ntawv thov ntawm diatomite muaj 5 qhov zoo: kev tiv thaiv hnub ci muaj zog, mos thiab lub teeb, thiab cov khoom zoo uas tuaj yeem tshem tawm cov pa phem ntawm cov tawv nqaij ntawm cov khoom ua npuas ncauj: lub peev xwm lub teeb, PH tus nqi nruab nrab, tsis muaj tshuaj lom, mos thiab du hmoov, kev ua tau zoo lub zog, kev tiv thaiv hnub thiab kev tiv taus kub siab. Diatomite yog siv rau hauv kev txheej, pleev xim, kev kho dej phwj thiab lwm yam lag luam. Cov khoom ntxiv txheej diatomite muaj cov yam ntxwv ntawm porosity loj, nqus tau zoo, tshuaj ruaj khov, hnav tsis kam, tiv taus kub, thiab lwm yam, uas tuaj yeem muab kev ua tau zoo ntawm qhov chaw, sib xws, tuab thiab txhim kho kev nplaum rau txheej. Vim nws qhov loj pore ntim, nws tuaj yeem luv lub sijhawm ziab ntawm zaj duab xis txheej. Nws kuj tseem tuaj yeem txo qhov ntau ntawm cov resin thiab txo tus nqi. Cov khoom no suav hais tias yog ib hom hmoov pleev xim zoo nrog kev ua tau zoo tus nqi. Nws tau siv dav hauv cov dej-raws li diatom av ua cov khoom xaiv los ntawm ntau lub tuam txhab pleev xim loj hauv ntiaj teb.
