Mica yog lub npe dav dav ntawm cov khoom siv roj silicate, nrog cov yam ntxwv ntawm rwb thaiv tsev, pob tshab, tiv tshav kub, tiv taus corrosion, yooj yim sib cais thiab tawm thiab tag nrho ntawm elasticity. Nws yog dav siv hauv tshuaj pleev ib ce, plastics, roj hmab, tshuaj pleev ib ce, tiv thaiv xeb, ua kom zoo nkauj, vuam, nrum, cov ntaub ntawv tsev thiab lwm cov teb, ua si lub luag haujlwm tseem ceeb hauv kev lag luam thiab kev tiv thaiv kev tsim kho.
I. Kev tshawb nrhiav thiab kev tsim khoom ntawm cov mica hluavtaws
Raws li "mica hluavtaws", thaum xyoo 1887, cov kws tshawb fawb Lavxias siv tshuaj fluoride los tso ua thawj daim fluoropoly mica los ntawm yaj; Los ntawm 1897, Tebchaws Russia tau kawm txog kev tsim cov kev ua haujlwm mineralizer hauv xyoo 1919, Lub Tebchaws Yelemees Siemens - Halske lub tuam txhab tau txais thawj daim ntawv patent. ntawm hluavtaws mica; Tebchaws Asmeskas tau nyob hauv txhua qhov kev tshawb fawb txog hluavtaws mica tom qab kev ua tsov rog zaum ob. Vim tias qhov ntsuas kub tsis kam, nws yog cov khoom siv tseem ceeb ntawm kev tiv thaiv thiab thev naus laus zis, Tebchaws Asmeskas txuas ntxiv mus tshawb fawb hauv daim teb no.
Nyob rau theem pib pg Tuam Tshoj, lub ntuj mica tuaj yeem txaus siab rau kev lag luam hauv teb chaws thiab kev txhim kho. Txawm li cas los xij, nrog txoj kev loj hlob sai ntawm lub zog, kev lag luam huab cua, ntuj mica tsis tuaj yeem ua raws li qhov yuav tsum tau ua. Qee cov koom haum Suav tau pib kawm mica hluavtaws.
Tshawb fawb kev tshawb fawb ua ke nrog tsev kawm ntawv, tsoomfwv thiab cov lag luam ua cov kev tshawb fawb thiab kev tsim cov hluavtaws mica nkag mus rau lub sijhawm paub tab txog tam sim no.
II. Qhov zoo ntawm hluavtaws mica piv nrog ntuj mica
(1) Lub hauv paus ruaj khov zoo vim yog siv tib lub mis thiab sib npaug ntawm cov khoom siv raw
(2) High purity & rwb thaiv tsev; tsis muaj qhov hluav taws xob twg
(3) Tsawg hlau tsis tshua muaj zog, ua tau raws li European thiab United lub xeev tus qauv.
(4) Cov lus ua tau zoo thiab whiteness (> 92), cov khoom siv ntawm cov nyiaj hlaws xim.
(5) Cov khoom siv ntawm pearly thiab crystal pigment
III. Kev Siv Tau Zoo ntawm cov khoom cua mica
Hauv kev lag luam mica, nws yog qhov tsim nyog los siv tag nrho ntawm mica seem ntawm ib daim ntawv loj mica Ntawm no yog kev siv cov hluavtaws mica raws li hauv qab no:
(1) hluavtaws mica hmoov
Nta: Zoo zawv zawg, muaj zog tiv thaiv thiab adhesion.
Daim ntawv thov: txheej, ceramic, anti-xeb thiab tshuaj lom neeg kev lag luam.
Huajing hluavtaws mica yus tus kheej ua tiav kev tsim kho, ua kom pom meej thiab lub ntsej muag loj, uas yog cov khoom zoo tshaj plaws ntawm cov hlaws xim.
(2) Khoom cua mica ceramics
Synthetic mica ceramics yog ib hom kev sib xyaw, uas muaj qhov zoo ntawm mica, ceramics thiab plastics. Nws muaj qhov ntev ruaj khov, zoo rwb thaiv tsev, thiab kub ua hauj.
(3) Cov khoom lag luam
Nws yog hom tshiab ntawm cov khoom siv tiv thaiv inorganic nrog qhov kub tsis kam, thiab tiv thaiv corrosion.
Qhov kom zoo dua: siab rwb thaiv tsev, tshuab muaj zog, tiv taus hluav taws xob, tiv thaiv oxidation thiab lwm yam.
(4) Khoom cua mica hluav taws xob cua sov phaj
Qhov no yog cov khoom siv tshiab ua haujlwm, uas yog tsim los ntawm txheej txheej txheej ntawm cov khoom siv semiconductor ntawm cov kab hluavtaws mica. Raws li cov khoom siv rau cov khoom vaj khoom tsev, nws tsis haus luam yeeb thiab tsis qab thaum muaj qhov kub thiab txias, yog li nws tau siv dav thiab tsim kho sai tam sim no.
(5) Khoom cua mica hlaws xim
Txij li mica hluavtaws yog cov khoom siv dag, cov khoom siv raw khoom tuaj yeem tswj tau qhov zoo. Yog li ntawd, cov hlau hnyav thiab lwm yam cuam tshuam tuaj yeem tiv thaiv tau los ntawm qhov pib .Qhov hluavtaws mica muaj lub siab huv, dawb, luster, kev nyab xeeb, tsis muaj tshuaj lom, tiv thaiv ib puag ncig, thiab kub tiv taus .Nws yog dav siv hauv txheej, yas, tawv, tshuaj pleev ib ce, textile, ceramic, lub tsev thiab kho kom zoo nkauj kev lag luam.Thaum qhov kev txhim kho ntawm cov khoom siv hluavtaws mica, nws muaj txiaj ntsig zoo hauv lub neej txhua hnub, kev lag luam cuam tshuam yuav txhawb nqa sai.
