M'malo ovuta kwambiri m'mafakitale, kukhazikika ndi chitetezo cha zingwe ndizofunikira kwambiri.
Zingwe zophimbidwa ndi tepi ya Mica — zomwe zimadziwika kuti zingwe za mica — zimagwiritsa ntchito tepi ya mica ngati chinthu choteteza moto, zomwe zimapangitsa kuti ikhale yolimba kwambiri komanso yoteteza magetsi. Izi zimapangitsa kuti ikhale njira yodalirika yotumizira magetsi pa kutentha kwambiri.
1. Ubwino Wofunika
(1) Kuteteza bwino komanso kukana moto
Zingwe za Mica zimagwiritsa ntchito tepi ya mica yoyera kwambiri ngati gawo lalikulu lotetezera kutentha.
Tepi ya mica yopangidwaSizimayaka ndipo zimasunga mphamvu yoteteza kutentha kwa mphindi zoposa 90 pa moto pakati pa 750°C ndi 1000°C, zomwe zimakwaniritsa miyezo ya GB/T 19666 Class A/B yolimbana ndi moto.
Kapangidwe kake ka silicate kapadera kamatseka bwino ma arc amagetsi ndi njira zopangira carbonization, zomwe zimapangitsa kuti ntchito ikhale yokhazikika panthawi yamoto kapena kutentha kwambiri.
(2) Kukana Kwambiri Kutentha Kwambiri
Ndi malo osungunuka mpaka 1375°C, tepi yopangidwa ndi mica imatha kugwira ntchito mosalekeza pa 600°C–1000°C.
Izi zimapangitsa kuti zingwe za mica zikhale zoyenera malo ovuta monga zitsulo, zoumba, kupanga magalasi, ndi kupanga magetsi, zomwe zimathandiza kuti kutentha kusungunuke kapena kuwonongeka.
(3) Mphamvu ndi Chitetezo Chowonjezereka cha Makina
Pambuyo pokulunga tepi ya mica, chingwecho nthawi zambiri chimalimbikitsidwa ndi kuluka kwa fiberglass kapena ulusi wagalasi wopanda alkali, zomwe zimapangitsa kuti chikhale cholimba kwambiri, chikhale cholimba, komanso chosavuta kusinthasintha - choyenera kugwiritsidwa ntchito pazinthu zosiyanasiyana zoyika.
2. Zofunika Kuganizira Posankha
(1) Mphamvu ya Makina pa Kutentha Kwambiri
Mica imakhala yolimba ikatentha kwambiri kwa nthawi yayitali, zomwe zingachepetse kupindika kapena mphamvu yokoka.
Pa zingwe zomwe zimagwiritsidwa ntchito m'malo ogwedezeka kapena osunthika, nyumba zolimba zimalimbikitsidwa.
(2) Malire a Voltage Class
Kuteteza tepi ya mica yokhala ndi gawo limodzi nthawi zambiri kumakhala koyenera pa ma voltages ochepera 600V.
Pakugwiritsa ntchito mphamvu yoposa 1kV, kapangidwe ka multilayer kapena composite insulation kamafunika kuti zitsimikizire kuti zikugwira ntchito bwino.
(3) Mtengo Wokwera Wopangira Zinthu
Chifukwa cha kuyera kwambiri kwa mica yopangidwa kapena fluorophlogopite komanso kulondola komwe kumafunika pakukulunga ndi kupukuta, zingwe za mica ndizokwera mtengo kuposa zingwe za silicone kapena PTFE — koma zimapereka chitetezo chosayerekezeka komanso chodalirika.
3. Kapangidwe ndi Zosankha za Zinthu
(1) Mtundu wa Kondakitala
Mkuwa Wopanda Chitsulo - wotsika mtengo, koma umakhala wovuta kuumitsa pamwamba pa 500°C.
Mkuwa Wokutidwa ndi Nickel – kukana dzimbiri komanso kulimba kwabwino.
Nikeli Yoyera - njira yabwino kwambiri yogwiritsira ntchito kutentha kwambiri (800°C+).
(2) Kapangidwe ka Tepi ya Mica
Tepi ya Mica Yophimbidwa - yodziwika bwino komanso yotsika mtengo; magwiridwe antchito amadalira mtundu wa tepi ya mica.
Tape ya Mica Yopangidwa ndi Sintered - yolumikizidwa bwino pambuyo pa kutentha kwambiri, imapereka chitetezo cholimba komanso kukana chinyezi bwino.
(3) Magiredi a Kutentha
Mtundu Wokhazikika (350°C–500°C) - nthawi zambiri umakhala wa phlogopite kapena mica yopangidwa ndi fiberglass.
Mtundu Wotentha Kwambiri (600°C–1000°C) - umagwiritsa ntchito mica yopangidwa bwino kwambiri komanso njira yopangira sintering kuti utetezedwe bwino.
(4) Miyezo Yopangira
China: GB/T 19666-2019 — Zingwe zoteteza moto komanso zosagwira moto.
Padziko Lonse: UL 5108, UL 5360 — yofotokoza ubwino wa tepi ya mica ndi kulondola kwa kukulunga.
4. Minda Yogwiritsira Ntchito
Makina Othandizira Kuzimitsa Moto: Kuzimitsa Moto, kuunikira mwadzidzidzi, kupulumutsa anthu, ndi njira zotetezera moyo.
Madera a Mafakitale Otentha Kwambiri: Mafakitale achitsulo, zitofu, malo opangira magetsi, ndi mawaya a zida zopangira.
Magalimoto Atsopano Ogwiritsa Ntchito Mphamvu: Mabatire, ma drive a mota, ndi makina owongolera kutentha.
Ndege ndi Chitetezo: Zipinda za injini ndi makina owongolera omwe amafunikira magwiridwe antchito opepuka komanso odalirika.
5. Chidule
Tepi ya Mica ndiye chinthu chofunikira kwambiri chomwe chimapangitsa kuti zingwe za mica zigwire bwino ntchito.
Kusankha mtundu woyenera wa mica, njira yokulunga, ndi zinthu zoyendetsera chingwe kumatsimikizira kuti chingwecho chikukwaniritsa zofunikira zamagetsi, kutentha, ndi makina zomwe zimagwiritsidwa ntchito.
Monga katswiri wopereka zinthu za chingwe,DZIKO LIMODZIimapereka matepi apamwamba kwambiri a mica komanso chithandizo chathunthu chaukadaulo pa njira zosiyanasiyana zotenthetsera komanso zosagwira moto.
