1. Chingwe cha Mica chopangidwa ndi mineral chotetezedwa ndi mkuwa
Chingwe choteteza mchere cha Mica tepi chokhala ndi chivundikiro cha mkuwa chopangidwa ndi kondakitala wamkuwa, choteteza tepi ya mica ndi chosakaniza chopangidwa ndi chivundikiro cha mkuwa, chokhala ndi magwiridwe antchito abwino a moto, kutalika kopitilira, mphamvu yochulukirapo, kugwiritsa ntchito bwino ndalama ndi zina zotero.
Njira yopangira chingwe cha mica mineral insulation cha corrugated copper sheathed cable imayamba ndi kulowetsedwa kosalekeza kwa waya wamkuwa kapena ndodo yamkuwa, zingwe zingapo za waya wamkuwa zimapindika, ndipo kondakitala imakulungidwa ndi kutentha kwambiri.tepi ya mica yopangidwa(tepi ya mica yokhala ndi calcium ingagwiritsidwe ntchito popanga zinthu zopanda halogen, utsi wochepa komanso poizoni wochepa), gawo loteteza kutentha limadzazidwa ndi ulusi wagalasi wopanda alkali, ndipo chingwecho chimakulungidwa ndi tepi ya mica yopangidwa yolimbana ndi kutentha kwambiri kuti ipange gawo loteteza. Chigoba cha mkuwa chimakulungidwa mu chitoliro cha mkuwa pambuyo poti tepi yamkuwa yakulungidwa ndi longitude, kenako chimapangidwa ndi corrugated yozungulira mosalekeza. Zofunikira zenizeni za chigoba chachitsulo sizingawonekere, ndipo chigoba cha polyolefin (chopanda utsi wochepa) chikhoza kuwonjezeredwa kunja.
Poyerekeza ndi zingwe zotetezedwa ndi magnesium oxide mineral, zinthu za mica mineral insulated corrugated copper sheathed cable products, kuwonjezera pa ntchito ya moto yomwe ili pafupi, zimatha kukhala ndi kutalika kwakukulu kosalekeza, mkati mwa 95 mm² zitha kupangidwanso kukhala zingwe zamagulu ambiri, kuti zithetse zofooka za zolumikizira zazikulu za chingwe. Komabe, weld ya corrugated copper payipi ndi yosavuta kusweka, extrusion deformation ndi single mica insulation, yomwe yakhalanso vuto lobadwa nalo, ndipo kufunika kwa njira yoyikirako kukadali kwakukulu kwambiri.
Malo owongolera a chingwe cha mica chomwe chimatetezedwa ndi mchere chomwe chimakutidwa ndi mkuwa ndi kusankha kwa zinthu zotentha kwambiri za mica lamba komanso njira yowotcherera ndi kuzunguliza chingwe cha mkuwa. Kusankha kwa zinthu zotentha kwambiri za mica kumakhudza mwachindunji magwiridwe antchito a chinthucho osapsa ndi moto. Tepi yochuluka kwambiri ya mica ingayambitse kutaya zinthuzo, ndipo zochepa sizingakwaniritse magwiridwe antchito osapsa ndi moto. Ngati kuwotcherera kwa jekete la mkuwa sikolimba, weld ya payipi ya mkuwa yolumikizidwa ndi mkuwa ndi yosavuta kusweka, nthawi yomweyo, kuya kwa kuzunguliza ndikofunikanso pakulamulira njira, kusiyana kwa kuya kwa kuzunguliza ndi kutsika kwa jekete la mkuwa kudzatsogolera ku kusiyana kwa malo enieni a jekete la mkuwa, motero kukhudza kukana kwa jekete la mkuwa.
2. Chingwe choteteza cha silicone cha ceramic rabara (mineral) chotetezedwa ndi refractory
Rabala ya silikoni ya CeramicChingwe choteteza moto chomwe chimatetezedwa ndi mchere ndi mtundu watsopano wa chingwe choteteza moto, chomwe chimateteza komanso chimateteza mpweya pogwiritsa ntchito zinthu zopangidwa ndi rabara ya silicone, ndipo chimakhala chofewa ngati rabara wamba wa silicone pansi pa kutentha kwabwinobwino, ndipo chimapanga chipolopolo cholimba cha ceramic pansi pa kutentha kwa 500 ℃ ndi kupitirira apo. Nthawi yomweyo, magwiridwe antchito a chotetezera moto amasungidwa, ndipo chingwecho chimatha kugwira ntchito bwino kwa nthawi inayake pakagwa moto, kuti chithandize kupulumutsa anthu ndikuchepetsa kuwonongeka ndi kutayika kwa katundu momwe zingathere.
Chingwe choteteza ku kuzizira cha silicone cha Ceramic silicone chokhala ndi chotetezera ku kuzizira (ceramic silicone raber composite material) chomwe chimagwiritsidwa ntchito ngati pakati pa chingwe, pakati pa pakati pa chingwecho pali chotetezera kuzizira kwambiri, monga ceramic silicone raber composite material, ndi chotetezera china, chomwe chimawoneka ngati chingwe chakunja kwa chivundikirocho. Mtundu uwu wa chinthu umadziwika ndi chotetezera ku kuzizira chomwe chimapangidwa ndi ceramic refractory silicone raber, ndipo chipolopolo cholimba chomwe chimapangidwa pambuyo pa ablation chikadali ndi chotetezera magetsi, chomwe chingateteze mizere yotumizira ndi kugawa ku kuwonongeka kwa moto, kuti zitsimikizire kuyenda bwino kwa mphamvu ndi kulumikizana, ndikupambana nthawi yopulumutsa yopulumutsa ndi kupulumutsa antchito pakagwa moto. Zinthu zoteteza ku moto za Ceramic zimaphatikizapo ceramic retardant fire silicone raber, ceramic fire composite tepi ndi ceramic fire retardant filling lamba.
Rabala ya ceramic silicone pa kutentha kwa chipinda siili ndi poizoni, yokoma, yofewa bwino komanso yotanuka, pa kutentha kwakukulu kuposa 500 ° C, zigawo zake zachilengedwe m'kanthawi kochepa kwambiri zimakhala chinthu cholimba chofanana ndi ceramic, kupanga chotchinga chabwino choteteza kutenthetsa, ndipo nthawi yoyaka ikakula, kutentha kukakwera, kuuma kwake kumakhala koonekeratu. Rabala ya ceramic silicone ilinso ndi zinthu zabwino zoyambira ndipo imatha kuchitika m'mizere yopangira vulcanization yokhazikika. Mpata ndi kutenthetsa kwa chingwe ndi rabala ya ceramic silicone, yomwe imatseka mpweya, ndipo chigoba cholumikizirana chimagwiritsidwa ntchito kupanga chigoba chosinthika cha chubu cha serpentine, chomwe chimatha kupirira kupsinjika kwa radial ndikuteteza chingwe ku kuwonongeka kwa makina akunja.
Mfundo zazikulu zoyendetsera ntchito yopanga chingwe cha silicone cha ceramic rabara chomwe chimatetezedwa ndi mchere makamaka zimakhala mu njira yolumikizira zida za vulcanization ndi interlocking ya rabara ya silicone ya ceramic.
Rabala ya ceramic silicone ili muzinthu zazikulu za rabala ya silicone yotentha kwambiri (HTV), kutanthauza kuti, rabala ya methyl vinyl silicone 110-2 yowonjezeredwa monga white carbon black, mafuta a silicone, ufa wa porcelain ndi zina zowonjezera pambuyo posakaniza kenako nkuwonjezeredwa ku makina awiri a vulcanization 24, osapangidwa kuti akhale olimba, osapangika bwino, amafunika kutentha kwa extruder kuti asunge kutentha kochepa, kutentha kwake kukakwera kuposa kumeneku, padzakhala chodabwitsa cha guluu wokhwima, zomwe zimapangitsa kuti chimbudzi chichotsedwe ndikuwonongeka kwa chotenthetsera. Kuphatikiza apo, chifukwa cha kulimba kochepa kwa rabala ya ceramic silicone, sichinganyamulidwe ndi screw kupita ku guluu, zomwe zimapangitsa kuti guluu lilowe m'malo mwake, zomwe zingayambitsenso chodabwitsa cha degumming. Pofuna kupewa mavuto omwe ali pamwambapa, momwe mungakonzere zida zoyenera za extruder, momwe mungasungire kutentha kochepa kwa extruder, komanso momwe mungapangire zinthu za rabala mu screw popanda mipata zakhala chinsinsi chotsimikizira mtundu wa chotenthetsera.
Zida zolumikizirana zimapangidwa ndi chubu chozungulira chokhala ndi zingwe zopingasa. Chifukwa chake, popanga, momwe mungakonzere mitundu yosiyanasiyana ya nkhungu zoyenera malinga ndi zofunikira zosiyanasiyana, m'lifupi ndi makulidwe a mzere womwe umagwiritsidwa ntchito polumikizira zida zolumikizirana ndiye chinsinsi chobweretsa mavuto a ndondomekoyi monga kusowa kwa chomangira cholimba.
