Hmoov Mica yog ib hom hmoov av uas muaj ntau yam ua ke, feem ntau yog ua los ntawm cov pob zeb txhuas silicate uas muaj cov yam ntxwv xws li kev rwb thaiv hluav taws xob, kev tiv taus cua sov, thiab kev ruaj khov ntawm tshuaj lom neeg. Lub ntsiab lus tseem ceeb ntawm hmoov mica yog potassium txhuas silicate nrog cov qauv crystalline flaky tshwj xeeb, thaum tseem muaj cov khoom tsis huv me me xws li hlau, magnesium, thiab sodium. Cov yam ntxwv tshwj xeeb ntawm lub cev thiab tshuaj lom neeg ntawm hmoov Mica ua rau nws yog ib yam khoom tseem ceeb hauv ntau yam lag luam thoob ntiaj teb, nrog rau kev siv hluav taws xob, kev pleev xim, kev pleev kom zoo nkauj, thiab kev tsim khoom siab heev.

1. Kev Tsim Hmoov Mica: Ib qho txuj ci tseem ceeb ntawm geological uas tau tsim los ntawm lub ntiaj teb lub plhaub thiab lub sijhawm

Cov khoom tseem ceeb ntawm cov hmoov mica ntuj yog cov zaub mov mica uas tsim tob hauv lub ntiaj teb lub plhaub. Thaum lub sijhawm ua haujlwm geological, cov magma nplua nuj txhuas thiab cov kua dej hydrothermal sib cuam tshuam hauv qab qhov kub thiab txias siab. Tau ntau lab xyoo, cov ntsiab lus no crystallize rau hauv mica cov qauv phyllosilicate sib txawv, tsim cov hauv paus zoo meej uas tso cai rau kev faib ua cov ntawv nyias, pob tshab. Synthetic mica yog tsim los ntawm kev tswj hwm qhov kub siab fusion ntawm quartz xuab zeb, txhuas oxide, thiab lwm yam khoom siv raw, tsim cov siv lead ua nrog kev huv thiab kev ua tau zoo dua. Thaum lub sijhawm ua tiav, mica yog zom rau hauv ntau qhov loj me me - los ntawm cov flakes loj (6-10 mesh) mus rau ultrafine hmoov (1250 mesh) - yog li tso lub hauv paus rau mica hmoov ntau yam kev siv.

Niaj hnub nim no, cov hmoov mica zoo tshaj plaws tau tsim tawm thoob ntiaj teb. Cov chaw tsim cov mica ntuj tseem ceeb suav nrog Is Nrias teb, Tuam Tshoj, Lavxias, thiab Tebchaws Meskas. Hauv Suav teb, cov chaw ua khoom tshwj xeeb hauv cov khoom siv mica qhuav, av ntub, thiab cov khoom siv mica tsim. Cov khoom no sib txawv hauv cov txheej txheem ua khoom thiab qib zoo (faib ua mica qhuav, av ntub mica, sericite mica, mica tsim, pearlescent mica, mica kub, thiab mica dub), tab sis lawv txhua tus khaws cov yam ntxwv tseem ceeb ntawm hmoov mica - kev rwb thaiv hluav taws xob zoo heev, kev ruaj khov thermal, thiab cov khoom me me platy uas tau los ntawm cov qauv siv lead ua ke tshwj xeeb.
