Mica tepi, yomwe imadziwikanso kuti refractory mica tepi, imapangidwa ndi makina a mica tepi ndipo ndi chinthu chotchinga chotchinga. Malinga ndi kugwiritsidwa ntchito, itha kugawidwa mu mica tepi ya ma motors ndi mica tepi ya zingwe. Malinga ndi kapangidwe kake, imatha kugawidwa mumitundu iwiri ya mica, imodzi-mbali imodzi ya mica, yachitatu-mu-imodzi, yapawiri filimu mica tepi, imodzi-filimu tepi, etc. Malinga ndi gulu mica, akhoza agawidwe mu tepi ya mica, phlogopite mica tepi, muscovite mica tepi.
Mawu Oyamba Mwachidule
Kutentha kwabwinobwino: tepi ya mica yopangidwa ndi yabwino kwambiri, tepi ya mica ya muscovite ndi yachiwiri, tepi ya phlogopite mica ndi yotsika.
Kutentha kotentha kwambiri: tepi ya mica yopangira ndiye yabwino kwambiri, tepi ya phlogopite mica ndi yachiwiri, tepi ya muscovite mica ndiyotsika.
Kutentha kosasunthika kwambiri: tepi ya mica yopangidwa popanda madzi akristalo, malo osungunuka 1375 ℃, malire akulu achitetezo, magwiridwe antchito apamwamba kwambiri. Phlogopite mica tepi imatulutsa madzi akristalo pamwamba pa 800 ℃, kukana kutentha kwakukulu ndi kwachiwiri. Muscovite mica tepi imatulutsa madzi akristalo pa 600 ℃, omwe ali ndi kukana kutentha kwambiri. Kuchita kwake kumabweranso chifukwa cha kuchuluka kwa makina a tepi ya mica.
Chingwe chosagwira moto
Mica tepi ya zingwe zachitetezo zosagwira moto ndi chida champhamvu kwambiri choteteza mica chokhala ndi kutentha kwambiri komanso kukana kuyaka. Mica tepi imakhala yosinthika bwino m'mikhalidwe yabwinobwino ndipo ndiyoyenera kusanjikiza kwambiri zosagwira moto pazingwe zosiyanasiyana zosagwira moto. Palibe volatilization ya utsi wovulaza ukakhala pamoto wotseguka, kotero mankhwalawa pazingwe sizothandiza komanso otetezeka.
Synthesis Mica Tape
Synthetic mica ndi mica yokumba yokhala ndi kukula kwakukulu ndi mawonekedwe a kristalo athunthu opangidwa pansi pazovuta zanthawi zonse posintha magulu a hydroxyl ndi ayoni a fluoride. Tepi yopangidwa ndi mica imapangidwa ndi pepala la mica monga chinthu chachikulu, ndiyeno nsalu ya galasi imayikidwa kumbali imodzi kapena mbali zonse ndi zomatira ndipo imapangidwa ndi makina a tepi ya mica. Nsalu yagalasi yomwe imayikidwa kumbali imodzi ya pepala la mica imatchedwa "tepi ya mbali imodzi", ndipo yomwe imayikidwa kumbali zonse ziwiri imatchedwa "tepi yamitundu iwiri". Kenako amaumitsa mu uvuni, kukulunga, ndikudula matepi amitundu yosiyanasiyana.
The synthetic mica tepi
Synthetic mica tepi ili ndi mawonekedwe a kukula kwakung'ono, mphamvu ya dielectric yayikulu, resistivity yayikulu, ndi yunifolomu ya dielectric yosasinthasintha ya tepi yachilengedwe ya mica. Chikhalidwe chake chachikulu ndi kukana kutentha kwambiri, komwe kumatha kufika pamlingo wa A-level kukana moto (950 一1000 ℃).
Kutentha kwa kutentha kwa tepi yopangira mica ndi yoposa 1000 ℃, makulidwe osiyanasiyana ndi 0.08 ~ 0.15mm, ndipo m'lifupi mwake ndi 920mm.
A.Three-in-one synthetic mica tepi: Amapangidwa ndi nsalu ya fiberglass ndi filimu ya poliyesitala kumbali zonse ziwiri, ndi mapepala a mica opangidwa pakati. Ndi tepi yotchinga, yomwe imagwiritsa ntchito utomoni wa amine borane-epoxy monga zomatira, polumikiza, kuphika, ndi kudula kuti apange.
B.Double-sided synthetic mica tepi: Kutenga mapepala a mica opangidwa ngati maziko, pogwiritsa ntchito nsalu za fiberglass monga zowonjezera mbali ziwiri, ndikugwirizanitsa ndi zomatira za silicone. Ndizinthu zabwino kwambiri zopangira waya ndi chingwe chosagwira moto. Ili ndi mphamvu yabwino kwambiri yolimbana ndi moto ndipo imayamikiridwa pazinthu zazikulu.
C.Single-sided synthetic mica tepi: Kutenga mapepala a mica opangidwa ngati maziko ndi nsalu za fiberglass monga zowonjezera mbali imodzi. Ndizinthu zabwino kwambiri zopangira mawaya ndi zingwe zosagwira moto. Ili ndi kukana bwino kwa moto ndipo imalimbikitsidwa pama projekiti akuluakulu.
Phlogopite Mica Tape
Tepi ya phlogopite mica ili ndi kukana kwamoto wabwino, kukana kwa asidi ndi alkali, anti-corona, anti-radiation properties, ndipo imakhala ndi kusinthasintha kwabwino komanso mphamvu zamakokedwe, zoyenera kuthamangitsidwa kothamanga kwambiri. Kuyesa kukana moto kumawonetsa kuti waya ndi chingwe chokulungidwa ndi tepi ya phlogopite mica imatha kutsimikizira kuti palibe kuwonongeka kwa 90min pansi pa kutentha kwa 840 ℃ ndi voteji 1000V.
Phlogopite fiberglass refractory tepi imagwiritsidwa ntchito kwambiri m'nyumba zazitali, njanji zapansi panthaka, malo opangira magetsi akuluakulu, komanso mabizinesi ofunikira a mafakitale ndi migodi komwe chitetezo chamoto ndi kupulumutsa moyo zimagwirizana, monga mizere yamagetsi ndi mizere yowongolera malo owopsa monga zida zozimitsa moto ndi magetsi owongolera mwadzidzidzi. Chifukwa cha mtengo wake wotsika, ndizomwe zimakondedwa pazingwe zosagwira moto.
A. Double-mbali mbali phlogopite mica tepi: Kutenga phlogopite mica pepala ngati maziko ndi fiberglass nsalu monga mbali ziwiri zolimbitsa zinthu, izo makamaka ntchito ngati zosagwira moto wosanjikiza wosanjikiza pakati waya pachimake ndi khungu lakunja la moto- chingwe chosagwira. Ili ndi mphamvu yabwino yolimbana ndi moto ndipo imalimbikitsidwa pama projekiti ambiri.
B. Single-sided phlogopite mica tepi: Kutenga pepala la phlogopite mica ngati maziko ndi nsalu za fiberglass monga zowonjezera mbali imodzi, zimagwiritsidwa ntchito makamaka ngati zosanjikiza zoteteza moto pazingwe zosagwira moto. Ili ndi mphamvu yabwino yolimbana ndi moto ndipo imalimbikitsidwa pama projekiti ambiri.
C.Three-in-one phlogopite mica tepi: Kutenga pepala la phlogopite mica monga maziko, nsalu ya fiberglass ndi filimu yopanda mpweya monga zowonjezera zowonjezera mbali imodzi, zomwe zimagwiritsidwa ntchito makamaka pazingwe zosagwira moto monga zosanjikiza zosagwira moto. Ili ndi mphamvu yabwino yolimbana ndi moto ndipo imalimbikitsidwa pama projekiti ambiri.
D.Double-film phlogopite mica tepi: Kutenga pepala la phlogopite mica ngati zinthu zoyambira ndi filimu yapulasitiki ngati zida zolimbikitsira mbali ziwiri, zimagwiritsidwa ntchito kwambiri pakumanga magetsi. Popanda kukana moto, zingwe zosagwira moto ndizoletsedwa.
E.Single-filimu phlogopite mica tepi: Kutenga phlogopite mica pepala monga zinthu m'munsi ndi pulasitiki filimu monga mbali imodzi kulimbikitsa chuma, izo makamaka ntchito kwa wosanjikiza magetsi kutchinjiriza. Popanda kukana moto, zingwe zosagwira moto ndizoletsedwa.
