Mu ntchito yaikulu yopanga mafakitale, mapaipi ali ngati "mitsempha yamagazi" yomwe imathandizira kugwira ntchito. Sikuti amangofunika kupirira kutentha kwambiri ndi dzimbiri, komanso kuthana ndi kuwonongeka komwe kumachitika chifukwa cha kuwonongeka kwa zinthu. Kupatuka pang'ono kungakhudze momwe ntchito ikuyendera komanso kungayambitse zoopsa zachitetezo. M'zaka zaposachedwapa, mtundu watsopano wa chitoliro chotchedwapayipi ya silicon carbidePang'onopang'ono yakhala yotchuka, ndipo chifukwa cha ubwino wake wapadera wogwirira ntchito, yakhala yankho lofunika kwambiri pazochitika zambiri zamafakitale. Lero, m'mawu osavuta, ndikuuzeni za "nyumba yolimba mtima" iyi m'mafakitale.
Silicon carbide - chinthu chosakhala chachitsulo chosapangidwa ndi zinthu zachilengedwe chomwe chili ndi kuuma kwachiwiri pambuyo pa diamondi, chapangidwa ndikuwotchedwa kudzera munjira zapadera kuti chikhale payipi yamafakitale yokhala ndi maubwino ambiri. Poyerekeza ndi mapaipi athu achitsulo wamba ndi mapaipi wamba apulasitiki, luso lake "loletsa kupanga" ndilapamwamba kwambiri.
Choyamba, imakhala ndi kukana dzimbiri kwambiri. Pakupanga mafakitale, n'kosapeweka kukhudzana ndi zinthu zowononga monga ma asidi amphamvu, ma alkali amphamvu, ndi njira zamchere. Mapaipi wamba posachedwa adzabowoka ndi dzimbiri, zomwe sizimangofunika kusinthidwa pafupipafupi komanso zingayambitse kutayikira kwa zinthu. Kapangidwe ka mankhwala a silicon carbide ndi kokhazikika kwambiri. Kupatula zinthu zingapo zapadera, imatha kukana dzimbiri la ma acid ambiri ndi ma alkali. Zili ngati kuyika "zoteteza dzimbiri" papaipi, zomwe zimakhala zokhazikika ngati Mount Tai mu mankhwala, ma electroplating ndi zina zowononga kwambiri.
Kachiwiri, ili ndi kukana kutentha kwambiri. Kukana moto kwa mapaipi a silicon carbide kumaposa kwambiri kwa zipangizo wamba, ndipo amathabe kugwira ntchito bwino kutentha kwambiri, ndi kukana kutentha kwa nthawi yayitali mpaka madigiri 1350, zomwe zimagwirizana bwino ndi mikhalidwe yambiri yogwirira ntchito kutentha kwambiri.
Kuphatikiza apo, kukana kutopa sikungafanane ndi kwina kulikonse. Ponyamula zinthu zokhala ndi tinthu tolimba monga mchenga ndi miyala, matope, ndi zina zotero, khoma lamkati la payipi lidzapitirira kusokonekera ndi kusokonekera, ndipo mapaipi achikhalidwe amawonongeka mosavuta, owonda komanso owonongeka. Kuuma kwa mapaipi a silicon carbide ndi kwakukulu kwambiri, ndipo "savulazidwa" ngakhale zinthu zitawonongeka kwa nthawi yayitali. Nthawi yawo yogwirira ntchito imakulitsidwa kwambiri poyerekeza ndi mapaipi wamba achitsulo, zomwe zingachepetse kwambiri mavuto ndi ndalama zomwe zimachitika chifukwa chosintha mapaipi pafupipafupi.
Kuphatikiza apo, mapaipi a silicon carbide ali ndi ubwino wobisika: makoma osalala amkati. Izi zikutanthauza kuti zinthuzo zimakhala ndi mphamvu zochepa panthawi yoyendera, zomwe zingachepetse kugwiritsa ntchito mphamvu, komanso sizimakula kwambiri, zomwe zimachepetsa zovuta zosamalira ndi kuyeretsa. Ngakhale kuti mtengo wake woyamba wogula ndi wokwera pang'ono kuposa wa mapaipi wamba, ubwino wake wogwiritsa ntchito bwino ndalama ndi wowonekera kwambiri chifukwa cha ndalama zosamalira, ndalama zosinthira, komanso kusunga mphamvu zomwe zimagwiritsidwa ntchito kwa nthawi yayitali.
Masiku ano, chifukwa cha kusintha kwa kupanga mafakitale kukhala kobiriwira komanso kogwira ntchito bwino, zofunikira pa zipangizo zamapaipi zikuchulukirachulukira. Mapaipi a silicon carbide amachita gawo lofunikira m'magawo osiyanasiyana monga uinjiniya wa mankhwala, mphamvu zatsopano, zitsulo, ndi kuteteza chilengedwe, chifukwa cha "machenjera awo atatu olimba" olimbana ndi dzimbiri, kukana kutentha kwambiri, komanso kukana kuvala, kukhala "ngwazi yosaoneka" polimbikitsa chitukuko chapamwamba cha mafakitale. Ndikukhulupirira kuti mtsogolomu, chitoliro champhamvuchi chidzalowa m'malo osiyanasiyana ndikugwiritsa ntchito zabwino zake zaukadaulo kuteteza kupanga mafakitale.
