Kabide ya silicon yopangidwa ndi reaction-sintered: njira yotchuka yopangira zinthu zotentha kwambiri

Pakugwiritsa ntchito kutentha kwambiri, kusankha zipangizo ndikofunikira kwambiri. Pakati pawo, zinthu za silicon carbide zomwe zimapangidwa ndi reaction-sintered zakhala chisankho chodziwika bwino chifukwa cha magwiridwe ake abwino kwambiri. Silicon carbide yomwe imagwiritsidwa ntchito ndi reaction-sintered ndi zinthu zopangidwa ndi ceramic zomwe zimapangidwa ndi reaction sintering ya carbon ndi silicon powder pa kutentha kwambiri.

Choyamba, silicon carbide yokhala ndi reaction-sintered ili ndi kukhazikika kwabwino kwambiri pa kutentha kwambiri. Imatha kusunga mphamvu zake zamakanika komanso kukhazikika kwa mankhwala pa kutentha kwambiri mpaka madigiri 2,000 Celsius. Izi zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pa kutentha kwambiri, monga m'mafakitale oyenga mafuta, zitsulo ndi ceramic.

Kachiwiri, silicon carbide yopangidwa ndi reaction-sintered imakhala ndi kukana kwabwino kwambiri kwa kuvala. Zipangizozi zimakhala ndi kukana kwabwino kwambiri kwa kuvala ndipo zimatha kukhalabe zokhazikika kwa nthawi yayitali m'malo ovuta komanso owonongeka. Chifukwa chake, imagwiritsidwa ntchito kwambiri m'minda yopera, kudula ndi zida zokwapula.

Kuphatikiza apo, silicon carbide yopangidwa ndi reaction-sintered ilinso ndi mphamvu yabwino kwambiri yoyendetsera kutentha komanso kusakhala ndi mphamvu kwa mankhwala. Imatha kutentha mwachangu ndipo imateteza dzimbiri m'malo owononga monga asidi ndi alkali. Izi zimapangitsa kuti igwiritsidwe ntchito kwambiri mumakampani opanga mankhwala ndi kasamalidwe ka kutentha.

Tiyenera kudziwa kuti njira yokonzekera reaction-sintered silicon carbide ndi yovuta kwambiri, imafuna kutentha kwambiri komanso zinthu zapadera zomwe zimachitika. Komabe, chifukwa cha kupita patsogolo kwa ukadaulo, njira yopangira zinthu yakhala ikukonzedwa pang'onopang'ono, zomwe zapangitsa kuti mtengo wa zinthuzo uchepe pang'onopang'ono, komanso kulimbikitsa kugwiritsidwa ntchito kwake m'magawo osiyanasiyana.

Mwachidule, monga chinthu chotentha kwambiri, silicon carbide yopangidwa ndi reaction-sintered ndi chisankho chabwino kwambiri pakugwiritsa ntchito kutentha kwambiri chifukwa cha kukhazikika kwake bwino pa kutentha kwambiri, kukana kuwonongeka, kutentha kwa mpweya komanso kusakhala ndi mphamvu kwa mankhwala. Pamene ukadaulo ukupitilira kukula, titha kuyembekezera kuti silicon carbide yopangidwa ndi reaction-sintered igwiritsidwe ntchito m'magawo ambiri ndikuwongolera magwiridwe antchito.
