Nws lub cev ua haujlwm feem ntau yog nyob ntawm qhov loj me, cleavage thiab hardness-txiav txim siab exfoliation muaj nuj nqi ntawm mica crystals, nrog rau cov xim pob tshab thiab elasticity ntawm mica. Kev lag luam mica feem ntau yog txheej txheej los yog phau ntawv zoo li cov muaju, nrog cov siv lead ua ntau qhov sib txawv ntawm ob peb millimeters mus rau kaum ntawm centimeters hauv tuab. Feem ntau, tsuas yog thaum muaj txiaj ntsig thaj chaw ntawmcov siv lead ua ntau dua los yog sib npaug rau 4cm2, nws muaj cov nqi siv ncaj qha.
Tau kawg, qhov loj dua qhov siv lead ua cheeb tsam, tus nqi siab dua. Lub splitting muaj nuj nqi ntawm mica nyob ntawm nws splitting thiab hardness. Cov qauv siv lead ua feem ntau ntawm mica ua rau nws muaj ntau yam hauv qab cleavage, uas tau dhau los ua ib qho tseem ceeb ntawm kev lag luam mica ua thiab exfoliation. Hauv txoj kev xav, muscovite thiab phlogopite tuaj yeem muab faib ua li 10, thiab phlogopite tuaj yeem muab faib ua li ntawm 5-10. Yog li ntawd, muscovite thiab phlogopite tuaj yeem tsim cov flakes tiaj tus ntawm txhua qhov tuab raws li kev tsim khoom lag luam kom ua tau raws li cov kev cai ntawm kev lag luam hluav taws xob thiab hluav taws xob.
Mica board muaj qhov zoo tshaj plaws kub rwb thaiv tsev ua haujlwm, siab kub kuj tuaj yeem ncav cuag 1000degree, ntawm cov ntaub ntawv kub rwb thaiv tsev, nws muaj cov nqi zoo heev. Nws muaj kev ua haujlwm zoo ntawm hluav taws xob rwb thaiv tsev, thiab kev tiv thaiv hluav taws xob tawg ntawm cov khoom siv dav dav yog siab li 20kV / mm. Nws kuj muaj lub zog flexural zoo heev thiab kev ua haujlwm muaj peev xwm. Cov khoom muaj siab flexural zog thiab zoo heev durability. Yuav ua tiav rau hauv ntau yam duab yam tsis muaj lamination. Kev tiv thaiv ib puag ncig zoo heev, cov khoom lag luam tsis muaj asbestos, thiab muaj pa taws tsawg dua thiab tsis hnov tsw thaum cua sov, txawm tias tsis muaj pa taws thiab tsis qab.
Thaum peb yuav, yuav kuaj li cas?
Tom qab kev yuav khoom, thov xyuas seb lub ntim sab nrauv puas zoo thiab puas yog cov khoom puas lawm?
Qhov thib ob, yog tias peb xa cov duab kos mus rau cov chaw tsim khoom, peb yuav tsum sib piv lawv raws li cov duab kos thiab xyuas seb lawv puas ua tau raws li cov qauv ntsuas.
