Chiyambi chachidule chokhudza mica yachilengedwe
Natural mica ndi mawu ambiri a mchere wa banja mica, ndipo silicate ndi dongosolo layered wa potaziyamu, aluminium, magnesium, chitsulo, lithiamu ndi zitsulo zina, kuphatikizapo biotite, phlogopite, muscovite, lepidolite, sericite, mica wobiriwira, ndi iron lithiamu Mica ndi zina zotero. Si dzina la mtundu wina wa thanthwe, koma dzina lambiri la mchere wa gulu la mica. Ndi silicate yokhala ndi potassium, aluminium, magnesium, iron, lithiamu ndi zitsulo zina. Ma minerals osiyanasiyana ali ndi zinthu zosiyanasiyana komanso njira zawo zopangira. Palinso kusiyana pang’ono, kotero pali kusiyana kwa maonekedwe, maonekedwe, ndi zamkati.
Mica ndi mchere wopanda zitsulo, womwe uli ndi zinthu zosiyanasiyana, makamaka kuphatikizapo SiO 2, zomwe zili pafupi ndi 49%, ndipo zomwe zili mu Al 2 O 3 ndi pafupifupi 30%. Ali ndi elasticity yabwino komanso kulimba. Insulation, kukana kutentha kwambiri, kukana kwa asidi ndi alkali, kukana kwa dzimbiri, kumamatira mwamphamvu ndi zina, ndizowonjezera zabwino kwambiri. Amagwiritsidwa ntchito kwambiri pazida zamagetsi, ndodo zowotcherera, mphira, mapulasitiki, kupanga mapepala, utoto, zokutira, inki, zoumba, zodzoladzola, zomangira zatsopano ndi mafakitale ena okhala ndi ntchito zosiyanasiyana. Ndi chitukuko chosalekeza cha sayansi ndi luso lamakono, anthu atsegula malo atsopano ogwiritsira ntchito.
Makhalidwe ake ndi kapangidwe kake kake: Makristalo a Muscovite ndi ma mbale ndi mizati ya hexagonal, malo olumikizana ndi athyathyathya, ndipo zophatikizika ndi ma flakes kapena mamba, motero amatchedwa mica yogawanika. Mica yachilengedwe ndi yoyera, yowonekera komanso yowoneka bwino, ndipo imakhala ndi mawonekedwe oyera komanso opanda mawanga. Mica ili ndi ubwino wotsutsa kutentha kwapamwamba (mpaka 1200 ℃ kapena kupitirira), resistivity yapamwamba (nthawi 1000 yapamwamba), kukana kwa asidi ndi alkali, kuwonekera, kupatukana ndi kusungunuka. Ndi pepala lopangidwa ndi mica insulating la spacecraft. Zida zofunika kwambiri monga ma sheet opangira ma mica insulating owunikira ma satelayiti ndi ma sheet opangidwa ndi mica polarized a radar phase shifters alinso ndi chiyembekezo chogwiritsa ntchito bwino pazachipatala ndi zaumoyo.
Monga wamba wosanjikiza kapangidwe aluminosilicate zachilengedwe mchere, mica ali wapadera kufala kuwala ndi ultraviolet kutchinga katundu, ndipo ali ndi ubwino wa kutchinjiriza mkulu magetsi, asidi ndi alkali kukana, ndi kutentha bata. Ndi chipangizo chamagetsi chosinthika komanso chowonekera m’tsogolomu. Zinthu zabwino m’minda monga. Komabe, zokolola zochepa ndi mtengo wapamwamba wa mica zachilengedwe zimachepetsa kwambiri kugwiritsa ntchito kwake.
