Yambitsani mitundu iwiri yodziwika ya machubu a mica

Mica chubu imagwiritsidwa ntchito kwambiri pakutchinjiriza kwamagalimoto ndi kutenthetsa kutentha, ndipo ndiyoyenera kutsekereza ndodo za ma elekitirodi kapena ma bushings otulutsira pamagetsi osiyanasiyana, ma mota, ng’anjo zamagetsi ndi zida zina. Chitoliro cha mica chubu ndi chinthu cholimba cha tubular insulating chopangidwa ndi mica kapena pepala la mica yokhala ndi zomatira zoyenera ndikumangirira kuzinthu zolimbitsa mbali imodzi. Iwo adagulung’undisa ndi kukonzedwa mu okhwima tubular insulating zakuthupi ndi mkulu mawotchi mphamvu.

Mica chubu yabwino imakhala ndi gloss yowala pamwamba, ndipo imatha kutulutsa mawu osasunthika kwambiri ikaponyedwa pansi. Zili ndi kutentha kwakukulu komanso mphamvu zamagetsi. Ndi zotetezeka kuyesa! Zofotokozera: Kutalika kwa chubu la mica ndi 300 ~ 500mm, ndipo m’mimba mwake ndi Φ6～ Φ300 mm.

Maonekedwe: Pamwamba ndi yosalala, popanda delamination, thovu ndi makwinya, pali zizindikiro za processing ndi yokonza koma si upambana chilolezo cha khoma makulidwe kulolerana, mkati khoma ali ndi makwinya pang’ono ndi zolakwika, ndipo malekezero awiri adulidwa bwino.

Njira yopangira mica chubu ndiyopadera kwambiri, makamaka yogawidwa m’mitundu iwiri: chubu cha muscovite ndi chubu cha phlogopite.

Muscovite chubu akhoza mosalekeza kuyesedwa pa kutentha pafupifupi 600-800 ℃, ndi phlogopite chubu akhoza mosalekeza kuyesedwa pa kutentha za 800-1000 ℃.

Phlogopite chubu ndi mtundu wa mchere wa mica, womwe ndi aluminosilicate wokhala ndi chitsulo, magnesium ndi potaziyamu. Ngati chitsulo mu phlogopite zikuchokera si kwambiri, angagwiritsidwe ntchito ngati magetsi insulating zakuthupi, choncho ali ndi udindo wofunika.

Phubu la phlogopite lili ndi phlogopite yakuda (mithunzi yosiyanasiyana ya bulauni kapena yobiriwira, ndi zina zotero) ndi phlogopite yowala (mitundu yosiyanasiyana yachikasu). Phlogopite yowala ndi yowonekera komanso yagalasi; phlogopite wamtundu wakuda ndi wowoneka bwino. Galasi wonyezimira ku semi-metal luster, ndipo cleavage pamwamba amawonetsa ngale.

Tsamba la chubu la phlogopite ndi losinthika komanso losayendetsa. Kuwala kopanda mtundu kapena kofiirira-wachikasu pansi pa maikulosikopu. Phlogopite yoyera ndi chinthu chabwino kwambiri chotetezera magetsi, ndipo imagwiritsidwanso ntchito kwambiri mu utoto weniweni wa miyala.

Makhalidwe onse ndi ofanana ndi chubu la muscovite, ndipo amasiyanitsidwa kwambiri ndi mica ina kutengera mtundu wake wa bulauni. Njira yopangira biotite, yomwe imakhala yofanana ndi mtundu, ndikung’amba ziwirizo kukhala zipsera zopyapyala ndikuziyika papepala loyera kuti zifananize. The phlogopite chubu ndi wotumbululuka chikasu bulauni, pamene biotite ndi imvi wobiriwira kapena utsi. Kuzindikiritsa zenizeni za phlogopite yopanda mtundu kapena mitundu ina kumafuna thandizo la maikulosikopu.

Ngati mukufuna kudziwa zambiri za mica chubu, chonde tifunseni kapena pitani kukampani.
