Yuav ua li cas lees txais lub rooj tsavxwm mica tom qab nws tuaj txog
Mica board yog cov khoom siv zoo li lub phaj siab, uas tseem tuaj yeem tswj hwm nws qhov kev ua tau zoo nyob rau hauv qhov kub thiab txias. Nws lub cev ua haujlwm feem ntau yog nyob ntawm qhov loj ntawm mica crystals, kev ua haujlwm tev tau txiav txim siab los ntawm kev sib cais thiab tawv, thiab xim pob tshab thiab elasticity ntawm mica. Muaj mica feem ntau yog nyob rau hauv daim ntawv ntawm cov txheej los yog phau ntawv zoo li cov muaju, thiab cov tuab ntawm cov siv lead ua loj li ntawm ob peb millimeters mus rau kaum ntawm centimeters. Feem ntau, tsuas yog thaj chaw muaj txiaj ntsig ntawm cov siv lead ua yog ntau dua lossis sib npaug ntawm 4cm2, nws muaj cov nqi siv ncaj qha.
Tau kawg, qhov loj dua qhov siv lead ua cheeb tsam, tus nqi siab dua. Kev ua haujlwm ntawm mica yog nyob ntawm qhov sib cais thiab hardness ntawm mica. Cov qauv siv lead ua ntau ntawm mica muab nws cov txheej txheem hauv qab cleavage, uas tau dhau los ua ib qho tseem ceeb ntawm kev lag luam mica ua thiab tev. Hauv txoj kev xav, muscovite thiab phlogopite tuaj yeem muab faib ua li 10, thiab phlogopite tuaj yeem muab faib ua 5-10. Yog li ntawd, muscovite thiab phlogopite tuaj yeem muab faib ua cov flakes tiaj tus ntawm txhua qhov tuab raws li kev tsim khoom lag luam kom tau raws li cov kev xav tau ntawm kev lag luam hluav taws xob thiab hluav taws xob rau mica.
mica board muaj qhov zoo tshaj plaws kub ua haujlwm rwb thaiv tsev kev ua tau zoo, siab kub tsis kam mus txog 1000 ℃, nyob rau hauv cov ntaub ntawv kub rwb thaiv tsev, muaj tus nqi zoo. Nrog cov khoom siv hluav taws xob zoo heev, qhov ntsuas hluav taws xob tawg ntawm cov khoom zoo tib yam yog siab li 20KV / mm. Nws kuj muaj zoo heev bending zog thiab kev ua tau zoo. Cov khoom muaj siab dabtsi yog khoov lub zog thiab zoo toughness. Nws tuaj yeem ua tiav hauv ntau yam duab yam tsis muaj delamination. Kev ua tau zoo ib puag ncig, cov khoom tsis muaj asbestos, muaj cov pa luam yeeb tsawg dua thiab tsw thaum rhuab, txawm tias tsis muaj pa taws thiab tsis qab.
Tsis tas li ntawd, seb lub rooj tsav xwm mica peb yuav tau muab daim ntawv teev npe zoo li cas, thiab seb nws puas ua tau raws li cov khoom lag luam uas kuv xav tau, los ntawm kev sib txuas lus nrog cov chaw tsim khoom, pab thiab txhim kho cov khoom tom qab muag thiab kev daws teeb meem hauv kev siv.
