Hoobkas nqe matte hluavtaws micas hmoov ntuj mica flakes rau epoxy resin pem teb
Mica yog lub npe dav dav ntawm cov minerals mica. Nws yog aluminosilicate ntawm potassium, txhuas, magnesium, hlau, lithium thiab lwm yam hlau, tag nrho cov no yog layered thiab monoclinic. Lub siv lead ua yog pseudohexagonal lamellae lossis phaj zoo li, qee zaum columnar. Lub lamellar cleavage yog tiav heev, nrog iav ci thiab elastic daim ntawv. Lub refractive index ntawm mica nce nrog rau qhov nce ntawm cov hlau, los ntawm qis protrusion mus rau nruab nrab protrusion. Cov hom tsis muaj hlau yog tsis muaj xim hauv flake. Cov hlau ntau dua, qhov tsaus dua xim, thiab ntau dua polychromatic thiab absorptive.
Mica flake loj: 6-10mesh, 10-20mesh,
Hmoov mica: 200mesh, 325mesh, 600mesh, 800mesh, 1250mesh, 2000mesh, 3000mesh thiab 5000mesh.
Daim Ntawv Thov
Hauv kev lag luam, biotite feem ntau siv nws cov rwb thaiv tsev thiab cua sov tiv taus, nrog rau kev tiv thaiv acid, alkali tiv taus, compression tiv taus thiab tev tawv tiv taus, ua cov khoom siv rwb thaiv tsev ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob; qhov thib ob, nws yog siv los tsim cov qhov rai thiab cov khoom siv kho tshuab ntawm cov boilers thiab smelting furnaces. Mica chips thiab mica hmoov tuaj yeem ua tiav rau hauv mica ntawv, thiab tseem tuaj yeem hloov mica daim ntawv los tsim ntau yam khoom siv rwb thaiv tsev pheej yig thiab sib npaug tuab.
Muscovite yog siv dav tshaj plaws hauv kev lag luam, ua raws li phlogopite. Nws yog siv dav hauv kev lag luam khoom siv hauv tsev, kev lag luam tua hluav taws, tus neeg tua hluav taws, vuam pas nrig, yas, rwb thaiv tsev hluav taws xob, ua ntawv, ntawv asphalt, roj hmab, xim pearlescent thiab lwm yam kev lag luam tshuaj lom neeg.
Ultrafine mica hmoov yog siv los ua cov khoom siv rau yas, pleev xim, pleev xim, roj hmab thiab lwm yam, uas tuaj yeem txhim kho nws lub zog kho tshuab, txhim kho kev tawv, kev nplaum, tiv thaiv kev laus thiab kev tiv thaiv corrosion.
ntawm no yog ntau hom mica ntuj siv ua cov ntaub ntawv rwb thaiv tsev hluav taws xob
Muaj ob hom mica: muscovite thiab phlogopite. Dawb mica muaj lub teeb ci ntsa iab thiab feem ntau tsis muaj xim thiab pob tshab; Kub mica muaj lub teeb ci ntsa iab thiab semi-metallic, nrog rau cov feem ntau yog daj kub, xim av, ntsuab daj, thiab lwm yam, tab sis tsis pom tseeb. Dawb mica thiab phlogopite muaj cov khoom siv hluav taws xob thiab kho tshuab zoo, tiv taus cua sov zoo, ruaj khov tshuaj lom neeg, thiab tiv taus corona. Ob hom mica tuaj yeem tev tawm thiab ua tiav rau hauv cov ntawv mos thiab elastic nyias nrog tuab ntawm 0.01 txog 0.03 millimeters. Kev ua haujlwm hluav taws xob ntawm muscovite zoo dua li ntawm phlogopite, tab sis phlogopite mos thiab tiv taus cua sov zoo dua li muscovite.
