Kufufuza za mkati mwa silicon carbide ceramics zomwe sizingawonongeke: chishango cholimba cha zida zamafakitale

Mu mafakitale amakono, zida nthawi zambiri zimakhala ndi malo ovuta ogwirira ntchito, ndipo kuwonongeka kwakhala chinthu chofunikira kwambiri chomwe chimakhudza magwiridwe antchito komanso ndalama zomwe zimagwiritsidwa ntchito.Chipinda cholimba cha silicon carbide ceramic chosagwira ntchito, monga chinthu chogwira ntchito bwino kwambiri, pang'onopang'ono ikubwera ndipo ikupereka njira zabwino kwambiri zosatha ntchito m'mafakitale ambiri. Lero, tiyeni tifufuze za kapangidwe ka silicon carbide ceramics komwe sikatha ntchito.

1, 'Mphamvu yoposa zonse' ya zoumbaumba za silicon carbide
Zida za silicon carbide (SiC) ndi zinthu zopangidwa ndi zinthu ziwiri, silicon ndi carbon. Ngakhale kuti zimapangidwa mosavuta, zimagwira ntchito bwino kwambiri.
1. Kuphulika kwa kuuma: Kuuma kwa silicon carbide ceramics ndi kochepa pang'ono poyerekeza ndi diamondi yolimba kwambiri. Izi zikutanthauza kuti imatha kukana kukanda ndi kudula tinthu tating'onoting'ono tolimba, komanso kukhalabe olimba m'malo ovuta kwambiri, monga kuyika zida zolimba pazida.
2. Kukana kuvala ndi kukana kupanga: Chifukwa cha kuuma kwake kwakukulu komanso kapangidwe kake kapadera ka kristalo, ziwiya za silicon carbide zimakhala ndi kukana kuvala bwino kwambiri. Pansi pa mikhalidwe yomweyi, kuchuluka kwake kovalidwa kumakhala kotsika kwambiri kuposa kwa zipangizo zachitsulo zachikhalidwe, zomwe zimakulitsa kwambiri moyo wa zidazo ndikuchepetsa nthawi ndi kutayika kwa ndalama komwe kumachitika chifukwa chosintha zigawo pafupipafupi.
3. Kukana kutentha kwambiri: Zida za silicon carbide nazonso zimakhala ndi kukana kutentha kwambiri ndipo zimatha kugwira ntchito mokhazikika kwa nthawi yayitali kutentha kwa 1400 ℃ kapena kupitirira apo. Izi zimapangitsa kuti ikhale ndi gawo lofunika kwambiri m'mafakitale otentha kwambiri monga kusungunula zitsulo, kupanga magetsi otentha, ndi zina zotero. Sizidzasintha, kufewetsa kapena kutaya magwiridwe ake oyambirira chifukwa cha kutentha kwambiri.
4. Kukhazikika kwa mankhwala: Kupatula zinthu zingapo monga hydrofluoric acid ndi concentrated phosphoric acid, silicon carbide ceramics zimakhala ndi kukana kwakukulu kwa ma acid ambiri amphamvu, maziko olimba, ndi zitsulo zosiyanasiyana zosungunuka, ndipo mphamvu zawo zamankhwala zimakhala zokhazikika kwambiri. M'mafakitale monga mankhwala ndi mafuta, omwe akukumana ndi zinthu zosiyanasiyana zowononga, amatha kuteteza zida ku dzimbiri ndikuwonetsetsa kuti zipangidwa bwino.

2, Zochitika Zogwiritsira Ntchito Zamkati Zosagwira Ntchito za Silikoni Carbide Ceramic
Kutengera ndi magwiridwe antchito abwino kwambiri omwe atchulidwa pamwambapa, silicon carbide ceramic lining yosatha kugwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.
1. Kukumba: Pakunyamula miyala, zinthu monga mapaipi opindika ndi ma chute zimakhala zosavuta kukhudzidwa ndi kuthamanga kwambiri komanso kukangana kuchokera ku tinthu ta miyala, zomwe zimapangitsa kuti iwonongeke kwambiri. Pambuyo poyika silicon carbide ceramic lining yosatha, kukana kwa zinthuzi kumawonjezeka kwambiri, ndipo nthawi yogwira ntchito imatha kuwonjezeredwa kuyambira miyezi ingapo mpaka zaka zingapo, zomwe zimathandiza kuchepetsa nthawi yokonza zida ndikuwonjezera magwiridwe antchito.
2. Makampani opanga magetsi: Kaya ndi chosungiramo ufa ndi njira yochotsera phulusa la mpweya m'malo opangira magetsi otentha, kapena makina osankha ufa ndi zotchingira mpweya za malo opangira simenti, zonsezi zimakumana ndi kuwonongeka kwakukulu kwa fumbi ndi kuwonongeka. Chipinda cholimba cha silicon carbide ceramic, chomwe chimakhala ndi kukana bwino kuvulala, chimachepetsa kuchuluka kwa kuwonongeka kwa zida, chimawonjezera nthawi yogwirira ntchito ya zida, komanso chimachepetsa nthawi yogwira ntchito chifukwa cha kulephera kwa zida, kuonetsetsa kuti magetsi ndi simenti zikugwira ntchito bwino.
3. Makampani Opanga Mankhwala: Kupanga mankhwala nthawi zambiri kumakhala ndi zinthu zosiyanasiyana zowononga monga ma asidi amphamvu ndi ma alkali, ndipo zida zimathanso kuwonongeka mosiyanasiyana panthawi yogwira ntchito. Chipinda cholimba cha silicon carbide ceramic sichimawonongeka ndi dzimbiri komanso sichimawonongeka, ndipo chimatha kusintha bwino malo ovuta ogwirira ntchito, kuonetsetsa kuti zida zamagetsi zikugwira ntchito bwino komanso moyenera. Muzochitika monga kupanga batri ya lithiamu yomwe imafunikira kuyera kwambiri kwa zinthu, imathanso kupewa kuipitsidwa kwa zitsulo ndikuwonetsetsa kuti zinthu zili bwino.
Chipinda cholimba cha silicon carbide ceramic chimapereka chitetezo chodalirika cholimba cha zida zamafakitale chifukwa cha magwiridwe ake abwino kwambiri, kukhala chothandiza champhamvu m'mafakitale ambiri kuti chiwongolere bwino ntchito yopanga ndikuchepetsa ndalama. Ngati kampani yanu ikukumananso ndi kuwonongeka kwa zida, mungaganizire kusankha chipinda chathu cholimba cha silicon carbide ceramic kuti muyambe gawo latsopano pakupanga bwino!
