Vim nws cov qauv ruaj khov, muaj pes tsawg leeg, xim dawb thiab tsis muaj tshuaj lom, diatomite tau dhau los ua cov khoom siv tshiab thiab zoo heev filling siv dav hauv roj hmab, yas, xim, tshuaj ntxuav tes, tshuaj thiab lwm yam kev lag luam. Nws tuaj yeem txhim kho qhov ruaj khov, elasticity thiab dispersity ntawm cov khoom, txhawm rau txhim kho lub zog, hnav tsis kam thiab acid tsis kam ntawm cov khoom. Piv txwv li, hauv kev lag luam tshuaj, nws tuaj yeem siv ua "dimethoate" hmoov muab tub lim thiab vitamin B muab tub lim; Hauv kev lag luam ntawv, nws tuaj yeem kov yeej cov teeb meem resin, txhim kho kev sib luag thiab pom tom qab ntxiv rau hauv cov ntaub so ntswg. Hauv kev lag luam roj hmab, nws tuaj yeem ua rau khau dawb, cov log tsheb liab liab; Hauv kev lag luam yas, nws tuaj yeem siv los ua cov khoom siv los tsim cov kua qaub, cov roj ua haujlwm, kev laus ua haujlwm ntawm lub zog siab yas yeeb nkab thiab phaj, nws qhov kev ua tau zoo yog ntau dua li cov khoom siv PVC; Nyob rau hauv cov khoom siv detergent, nws yog siv los ua tus neeg sawv cev pabcuam es tsis txhob siv sodium tripolyphosphate, thiab cov khoom siv hluavtaws ua tau muaj cov yam ntxwv zoo ntawm cov npuas dej tsawg, kev ua haujlwm siab thiab tsis muaj kuab paug.
Ntuj diatomite tsis tsuas yog muaj qee yam tshuaj muaj pes tsawg leeg, tab sis kuj muaj cov qauv ntxeem tau zoo, xws li thaj chaw zoo, qhov ntim ntawm qhov pore thiab qhov pore loj faib, yog li nws dhau los ua cov cab kuj zoo heev ntawm vanadium catalyst rau tsim sulfuric acid. Cov neeg nqa khoom zoo diatomite tuaj yeem ua rau muaj kev ua haujlwm ntawm vanadium catalyst, txhim kho thermal stability, txhim kho lub zog thiab ua kom lub neej ntev. Diatomite kuj yog ib qho tseem ceeb ntawm cov cement sib xyaw. Cov hmoov diatomite yog ci ntawm 800 ~ 1000 ℃ thiab tov nrog Portland cement los ntawm 4: 1 los ntawm qhov hnyav los ua cov khoom sib xyaw ua kom sov. Cov hom tshwj xeeb ntawm cov cement ua los ntawm diatomite tuaj yeem siv tau raws li qhov hnyav tshwj xeeb cement hauv cov roj drilling, lossis hauv cov khoom tawg thiab ntxeem tau los tiv thaiv kev poob ntawm cov cement slurry thiab tiv thaiv cov cement slurry los ntawm hnyav dhau los thaiv cov roj tsawg thiab roj av.
