Cov khoom xyaw hmoov talcum sib txawv rau kev siv hauv cov khoom siv ceramic

Xwm:Hmoov dawb mus rau dawb tawm. Lub ntsiab tivthaiv ntawm talc yog hydrous magnesium silicate, cov tshuaj molecule yog Mg3 [S14 010] (OH)2, thiab cov qauv yog cov pob zeb silicate txheej. Magnesium (Mg) yuav tsum yog 17.0% txog 19.5%. Qhov ceev sib piv 2.75. Cov qauv mos thiab creamy. Cov talc superfine tswj cov qauv txheej ntawm cov talc ntuj, thiab tib lub sijhawm, qhov kev sib kis thiab kev dawb tau pom tseeb zoo dua, thiab kev txhawb nqa zoo dua. Talc muaj ntau yam ntxwv xws li kev ruaj khov tshuaj lom neeg, qhov chaw yaj siab, qhov kub tshwj xeeb loj, kev ua haujlwm thermal qis, kev ua haujlwm hluav taws xob qis, qhov nrawm qis, muaj peev xwm nqus roj tau zoo, tiv taus kua qaub thiab alkali, thiab lwm yam.

Cov Lus Qhia Txog Khoom

Cov Cim Npe Khoom

Txoj Kev Tsim Khoom

Cov talc ore raug xa mus rau lub tshuab zeb rauj kom zom cov khoom loj, thiab cov khoom uas raug zom lawm raug xa mus rau lub tshuab ziab ntsug kom ziab los ntawm lub thoob nqa thiab lub tshuab pub mov vibrating. Tom qab ziab lawm, cov khoom raug zom los ntawm lub tshuab zeb rauj. Cov khoom uas raug zom nruab nrab nkag mus rau hauv lub tshuab pulverizer los ntawm lub hopper pub rau kev zom, thiab cov khoom uas raug zom lawm raug thauj mus rau lub tshuab jet pulverizer rau kev zom zoo heev kom tau cov khoom uas muaj qhov loj ntawm 500-5000 mesh.

Cov cwj pwm

Cov khoom no yog ib hom hmoov dawb los yog dawb tawm, tsis yog hmoov av me me uas muaj qhov zoo li nplua. Cov khoom no tsis yaj hauv dej, dilute hydrochloric acid los yog 8.5% sodium hydroxide kua.

Siv

Nws yog siv los ua cov khoom sau rau cov yas, txhim kho kev ua haujlwm ntawm cov khoom, thiab txhim kho lub zog kho tshuab, tiv taus cua sov thiab lub zog tensile ntawm cov khoom. Thaum siv rau hauv cov yeeb yaj kiab yas, nws tuaj yeem ua rau cov yeeb yaj kiab yas kis tau rau lub teeb tawg. Ntxiv hmoov talcum rau cov xim thiab cov txheej txheem tuaj yeem txhim kho kev sib kis, kev ntws thiab kev ci ntsa iab. Kev ua haujlwm ntawm alkali corrosion, thiab tiv taus dej zoo, tiv taus kev ua qias tuaj, tiv taus kev laus, tiv taus kev hnav, tiv taus pa thiab kev ruaj khov tshuaj lom neeg, thiab muaj cov khoom tiv taus hluav taws kub, ntxiv rau hloov qee cov titanium dioxide. Talc kuj tseem siv los ua cov khoom sau ntaub thiab cov neeg sawv cev dawb; tus nqa khoom thiab cov khoom ntxiv rau tshuaj thiab khoom noj.
