Chipinda chopopera cha silicon carbide slurry: chisankho chabwino kwambiri choyendera mafakitale

Mu mafakitale ambiri opanga zinthu, nthawi zambiri pamafunika kunyamula zakumwa zokhala ndi tinthu tolimba, zomwe timazitcha kuti slurry. Kufunika kumeneku kumachitika kwambiri m'mafakitale monga migodi, zitsulo, mphamvu, ndi uinjiniya wa mankhwala. Ndipompope wothira madziNdi chipangizo chofunikira kwambiri chomwe chimayang'anira ntchito zonyamula. Pakati pa zinthu zambiri zomwe zili mu pampu ya slurry, mkati mwake mumakhala ndi gawo lofunika kwambiri chifukwa chimakhudza mwachindunji slurry. Sikuti chimangolimbana ndi kuwonongeka ndi kuwonongeka kwa tinthu tolimba mu slurry, komanso chimapirira dzimbiri la mankhwala osiyanasiyana. Malo ogwirira ntchito ndi ovuta kwambiri.
Zipangizo zachikhalidwe zogwirira ntchito za mapampu otayira madzi, monga chitsulo ndi rabala, nthawi zambiri zimakhala ndi zofooka zina zikakumana ndi zovuta zogwirira ntchito. Ngakhale kuti chitsulocho chili ndi mphamvu zambiri, kukana kwake kutopa ndi kukana dzimbiri n'kochepa. Kugwiritsa ntchito kwa nthawi yayitali kungayambitse kuwonongeka ndi dzimbiri mosavuta, zomwe zimapangitsa kuti zida zisamaliridwe nthawi zambiri komanso kufupikitsidwa kwa nthawi yogwira ntchito. Kukana kuwonongeka ndi kukana dzimbiri kwa raba ndikwabwino, koma magwiridwe antchito awo adzachepa kwambiri kutentha kwambiri, kuthamanga kwambiri, kapena malo amphamvu okhala ndi asidi, omwe sangakwaniritse kufunikira kwakukulu kwa mafakitale.
Kutuluka kwa zinthu za silicon carbide kwabweretsa yankho labwino kwambiri pa vuto la mapampu a slurry. Silicon carbide ndi mtundu watsopano wa zinthu za ceramic zomwe zili ndi zinthu zambiri zabwino, monga kuuma kwake kwakukulu, kwachiwiri pambuyo pa diamondi. Izi zimathandiza kuti silicon carbide lining ipewe kuwonongeka kwa tinthu tolimba mu slurry, zomwe zimapangitsa kuti pampu ya slurry isawonongeke; Ilinso ndi kukana dzimbiri bwino ndipo imatha kupirira mitundu yonse ya ma inorganic acid, organic acid, ndi alkalis. Ili ndi mitundu yosiyanasiyana ya ma inorganic acids omwe amafunikira kukana dzimbiri kwambiri; Silicon carbide ili ndi kukhazikika kwabwino kwa mankhwala ndipo imatha kusunga magwiridwe antchito okhazikika pansi pa mikhalidwe yovuta kwambiri monga kutentha kwambiri ndi kuthamanga kwambiri. Simakumana ndi zovuta za mankhwala mosavuta, zomwe zimapangitsa kuti izigwira ntchito bwino m'malo osiyanasiyana amafakitale.

Poganizira za zotsatira zogwiritsidwa ntchito, ubwino wa mapampu a silicon carbide slurry ndi woonekeratu. Choyamba, nthawi yake yogwirira ntchito imawonjezeka kwambiri. Poyerekeza ndi zipangizo zachikhalidwe, kukana kwa silicon carbide lining kumatha kufika kangapo kuposa ma alloys ambiri osavala chromium, zomwe zingachepetse kwambiri nthawi yokonza ndi kusintha zida, ndikuchepetsa ndalama zogwirira ntchito zamabizinesi. Kachiwiri, chifukwa cha pamwamba pake posalala pa silicon carbide lining, imatha kuchepetsa bwino kukana kwa slurry panthawi yoyendera, kukonza magwiridwe antchito a pampu, ndikusunga mphamvu. Kuphatikiza apo, kukhazikika kwa silicon carbide lining ndi kwakukulu, komwe kumatha kusintha malo osiyanasiyana ogwirira ntchito ovuta ndikupereka chitsimikizo champhamvu cha kupitiliza ndi kukhazikika kwa kupanga mafakitale.
Chopopera cha silicon carbide slurry, monga chinthu chogwira ntchito bwino kwambiri, chawonetsa ubwino ndi kuthekera kwakukulu m'munda wa mayendedwe a mafakitale. Chifukwa cha kupita patsogolo kwa ukadaulo komanso kuchepa pang'onopang'ono kwa ndalama, akukhulupirira kuti chidzagwiritsidwa ntchito kwambiri m'mafakitale ambiri, kupereka chithandizo champhamvu pakukula kwa kupanga mafakitale.
