Ntau qib kev lag luam talcum hmoov cov khoom xyaw rau kev siv ceramic

Xwm:Dawb mus rau dawb hmoov.Cov khoom tseem ceeb ntawm talc yog hydrous magnesium silicate, cov tshuaj molecule yog Mg3 [S14 010] (OH)2, thiab cov qauv yog txheej txheej silicate mineral.Mgnesium (Mg) yuav tsum yog 17.0% mus rau 19.5%.Tus txheeb ze ntom ntom 2.75.Mos thiab creamy kev ntxhib los mos.Lub superfine talc tswj cov txheej txheem txheej txheem ntawm ntuj talc, thiab tib lub sijhawm, cov dispersibility thiab whiteness yog pom tseeb txhim kho, thiab lub zog yog zoo dua.Talc muaj ntau yam ntxwv xws li tshuaj stability, siab melting point, loj tshwj xeeb tshav kub, tsis tshua muaj thermal conductivity, hluav taws xob conductivity, tsawg shrinkage tus nqi, muaj zog roj nqus peev xwm, acid thiab alkali tsis kam, thiab lwm yam.

Txoj kev tsim khoom

Cov talc ore raug xa mus rau ib lub rauj zeb rau ntxhib crushing, thiab cov khoom pulverized xa mus rau lub tshuab ntsug ntsug kom qhuav los ntawm lub thoob of elevator thiab vibrating feeder.Tom qab ziab, cov khoom yog pulverized los ntawm ib tug rauj zeb.Cov khoom nruab nrab crushed nkag mus rau hauv pulverizer los ntawm cov khoom noj hopper rau pulverization, thiab cov khoom pulverized yog thauj mus rau lub dav hlau pulverizer rau ultra-fine pulverization kom tau ib yam khoom nrog ib tug fineness ntawm 500-5000 mesh.

Cov yam ntxwv

Cov khoom no yog ib qho dawb los yog tawm-dawb, uas tsis yog-gritty hmoov zoo nrog ib tug nplua zoo.Cov khoom no yog insoluble hauv dej, dilute hydrochloric acid los yog 8.5% sodium hydroxide tov.

Siv

Nws yog siv los ua cov khoom ntim rau cov yas, txhim kho kev ua haujlwm, thiab txhim kho cov khoom siv dag zog, ua kom sov thiab tensile lub zog ntawm cov khoom.Thaum siv rau hauv cov yeeb yaj kiab yas, nws tuaj yeem ua rau kom xa cov yeeb yaj kiab yas mus rau lub teeb tawg.Ntxiv talcum hmoov rau cov xim thiab coatings tuaj yeem txhim kho dispersion, fluidity thiab gloss.Alkali corrosion kev ua tau zoo, thiab dej tsis kam, muaj kuab paug ua haujlwm, muaj zog tiv thaiv kev laus, hnav tsis kam, chav ua haujlwm thiab tshuaj lom neeg ruaj khov, thiab muaj cov nplaim hluav taws muaj zog, ntxiv rau hloov qee cov titanium dioxide.Talc kuj tseem siv tau los ua textile muab tub lim thiab ntxuav hniav dawb;ib tug nqa thiab additive rau tshuaj thiab zaub mov.
