Diatomite yog pob zeb sedimentary siliceous biogenic, feem ntau yog tsim los ntawm cov seem ntawm diatoms thaum ub. Nws cov tshuaj lom neeg muaj pes tsawg leeg yog SiO2, muaj me ntsis Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5 thiab cov organic matter. Cov khoom siv hauv diatomite feem ntau yog opal thiab nws cov ntau yam, ua raws li cov av nplaum minerals-hydromica, kaolinite thiab cov mineral debris. Cov mineral debris muaj xws li Shi Ying, feldspar, biotite thiab organic matter. Cov organic matter muaj ntau ntawm cov kab me me mus rau ntau dua 30%. Diatomite yog dawb, greyish dawb, grey thiab lub teeb greyish xim av, thiab muaj cov khoom zoo, xoob, lub teeb, porous, absorbent thiab permeable.
Cov khoom siv ntxiv rau diatomite txheej, nrog cov porosity loj, kev nqus tau zoo, kev ruaj khov tshuaj lom neeg, kev tiv thaiv kev sib txhuam, cua sov
kev ua haujlwm tsis kam thiab lwm yam ntxwv, tuaj yeem muab cov khoom zoo heev ntawm cov txheej txheem, kev sib raug zoo, thickening thiab adhesion. Vim nws qhov loj ntawm qhov pore, nws tuaj yeem ua rau lub sijhawm qhuav luv dua. Kuj tseem tuaj yeem txo cov resin ntau, txo cov nqi.

Daim ntawv thov tseem ceeb
Nws ib txwm siv rau hauv cov xim latex, xim phab ntsa sab hauv thiab sab nraud, xim alkyd resin, xim polyester thiab lwm yam txheej txheem,
tshwj xeeb tshaj yog nyob rau hauv kev tsim cov txheej txheem architectural.
Thaum siv cov xim pleev xim thiab pleev xim, qhov ci ntsa iab ntawm cov zaj duab xis txheej tuaj yeem tswj tau sib npaug, qhov kev tiv thaiv kev sib txhuam thiab kev khawb ntawm cov zaj duab xis txheej tuaj yeem nce ntxiv, cov dej noo thiab deodorization tuaj yeem tshem tawm, huab cua tuaj yeem ntxuav tau, thiab cov yam ntxwv ntawm kev rwb thaiv suab, dej tsis nkag, rwb thaiv cua sov thiab permeability zoo tau ua tiav.

Diatom av nkos feem ntau yog tsim los ntawm cov khoom siv inorganic ntuj ntshiab, yog cov khoom siv tiv thaiv ib puag ncig ntsuab, nws tus kheej tsis muaj kuab paug, tsis muaj ntxhiab tsw. Dialgae av nkos muaj kev tiv thaiv ib puag ncig ntuj, kev siv tshuab tes, kev tswj av noo, huab cua
kev ntxuav, kev tiv thaiv hluav taws, kev nqus suab thiab txo suab nrov, kev txuag cua sov thiab kev rwb thaiv tsev, kev tiv thaiv qhov muag, phab ntsa
kev ntxuav tus kheej, lub neej ntev thiab lwm yam ntxwv thiab kev ua haujlwm, yog xim latex thiab ntawv phab ntsa thiab lwm yam khoom dai kom zoo nkauj ib txwm muaj
cov ntaub ntawv tsis tuaj yeem sib piv.
Cov khoom siv ntxiv rau diatomite muaj cov yam ntxwv ntawm cov porosity loj, kev nqus tau zoo, cov khoom siv tshuaj ruaj khov, kev hnav tsis kam thiab kev tiv taus kub.
