Hmoov talc yog ib yam khoom siv hauv kev lag luam. Nws yog ib hom magnesium silicate mineral talc group. Lub ntsiab tivthaiv yog aqueous magnesium silicate. Tom qab tsoo, nws raug kho nrog hydrochloric acid, ntxuav nrog dej thiab ziab.
Hmoov Talc muaj cov khoom zoo heev rau lub cev thiab tshuaj xws li lubricity, tiv taus hluav taws, tiv taus acid, rwb thaiv tsev, melting point siab, tshuaj lom neeg tsis ua haujlwm, npog zoo, mos, ci ntsa iab thiab nqus tau zoo.
Hmoov Talc feem ntau yog siv los ua cov khoom ntim rau cov yas thiab cov ntawv, cov roj hmab ntim thiab cov neeg sawv cev tiv thaiv kev nplaum ntawm cov khoom roj hmab, cov xim zoo, thiab lwm yam.

Talc muaj cov khoom zoo heev rau lub cev thiab tshuaj xws li lubricity, anti adhesion, flow aid, fire resistance, acid resilient, melting point siab, inactive chemical functions, well sheet strength, softness, ci ntsa iab, thiab adsorption zoo. Vim nws cov qauv siv lead ua ke, talc yooj yim faib ua nplai thiab lubricity tshwj xeeb. Yog tias Fe2O3 muaj ntau, nws yuav txo nws cov rwb thaiv tsev.
