Reaction-sintered silicon carbide: kusankha kotchuka kwa zida zotentha kwambiri

Pazogwiritsa ntchito kutentha kwakukulu, kusankha kwazinthu ndikofunikira. Pakati pawo, zinthu zochitira-sintered silicon carbide zakhala chisankho chodziwika bwino chifukwa chakuchita bwino. Reaction-sintered silicon carbide ndi chinthu cha ceramic chomwe chimapangidwa ndi momwe sintering ya kaboni ndi silicon ufa pa kutentha kwambiri.

Choyamba, reaction-sintered silicon carbide imakhala ndi kutentha kwapamwamba kwambiri. Imatha kukhalabe ndi mphamvu zamakina komanso kukhazikika kwamankhwala pakutentha kwambiri mpaka madigiri 2,000 Celsius. Izi zimapangitsa kukhala koyenera kwa ntchito zotentha kwambiri, monga zoyenga mafuta, zitsulo ndi mafakitale a ceramic.

Kachiwiri, reaction-sintered silicon carbide imakhala ndi kukana kwabwino kwambiri. Zinthuzi zimakhala ndi kukana kwabwino kwambiri ndipo zimatha kukhala zokhazikika kwa nthawi yayitali pamakangano owopsa komanso mavalidwe. Choncho, amagwiritsidwa ntchito kwambiri m'madera akupera, kudula ndi zida zowononga.

Kuphatikiza apo, reaction-sintered silicon carbide imakhalanso ndi matenthedwe abwino kwambiri komanso inertia yamankhwala. Imatha kutentha mwachangu ndikuwonetsa kukana kwa dzimbiri m'malo owononga monga asidi ndi alkali. Izi zimapangitsa kuti zigwiritsidwe ntchito kwambiri mumakampani opanga mankhwala komanso kasamalidwe kamafuta.

Kuyenera kudziŵika kuti kukonzekera ndondomeko anachita-sintered pakachitsulo carbide ndi zovuta, amafuna kutentha ndi zinthu zapadera anachita. Komabe, ndi kupita patsogolo kosalekeza kwaukadaulo, njira yopangira idasinthidwa pang'onopang'ono, ndikupangitsa mtengo wazinthuzo kuchepetsedwa pang'onopang'ono, ndikulimbikitsa kugwiritsa ntchito kwake m'magawo osiyanasiyana.

Mwachidule, monga zinthu zotentha kwambiri, reaction-sintered silicon carbide ndi njira yabwino kwambiri yopangira kutentha kwakukulu chifukwa cha kukhazikika kwake kwa kutentha kwambiri, kukana kuvala, matenthedwe amafuta ndi inertia yamankhwala. Pomwe ukadaulo ukupitilira kukula, titha kuyembekezera kuti sintered silicon carbide igwiritsidwe ntchito m'magawo ambiri komanso kupititsa patsogolo magwiridwe antchito.
