Njira yopangira mafakitale ya silicon carbide yopangidwa ndi reaction-sintered ndikutulutsa mchenga wa quartz wapamwamba kwambiri ndi calcined petroleum coke mu uvuni wotenthetsera wamagetsi. Mabuloko a silicon carbide oyeretsedwa amapangidwa kukhala zinthu zokhala ndi magawidwe osiyanasiyana a tinthu powaphwanya, kutsuka ndi asidi wamphamvu ndi alkali, zida zolekanitsa maginito komanso kuyeretsa kapena kulekanitsa madzi.
Silicon carbide ili ndi mitundu iwiri yodziwika bwino ya silicon carbide yakuda ndi silicon carbide yobiriwira, zonse zomwe ndi za α-SiC. ① Silicon carbide yakuda ili ndi pafupifupi 95% SiC, ndipo kulimba kwake kuli kokwera kuposa silicon carbide yobiriwira, yomwe yambiri imagwiritsidwa ntchito popanga ndi kukonza zinthu zopangira zomwe zili ndi mphamvu zochepa zomangika, monga galasi lopaka, porcelain, miyala, refractory, chitsulo cha nkhumba ndi zitsulo zamtengo wapatali. ② Silicon carbide yobiriwira ili ndi SiC pafupifupi 97% kuposa pamenepo, kudzinola yokha ndikwabwino, yambiri imagwiritsidwa ntchito popanga ndi kukonza zida za carbide, chitsulo cha titanium ndi magalasi owonera, ndipo imagwiritsidwanso ntchito pokongoletsa silinda ndi kupukuta zida zachitsulo zothamanga kwambiri. Kuphatikiza apo, pali ma cubic metres a silicon carbide, omwe ndi kristalo wobiriwira wopepuka wopangidwa ndi njira yatsopano, ndipo amagwiritsidwa ntchito kupanga nkhungu yoyenera kunyamula zinthu zapamwamba, zomwe zingapangitse kuti pamwamba pa Ra32 ~ 0.16μm pakhale kukonzedwa mpaka Ra0.04 ~ 0.02μm.
Kugwiritsa ntchito kwakukulu kwa silicon carbide yotsutsana ndi reaction sintering
(1) Monga chinthu chosawonongeka, chingagwiritsidwe ntchito ngati nkhungu, monga gudumu la mchenga, miyala yozungulira, gudumu lopera, matailosi amchenga, ndi zina zotero.
(2) Monga chochotsera poizoni ndi zinthu zosagwira dzimbiri m'makampani opanga zitsulo. Silicon carbide imaphatikizapo ntchito zinayi zazikulu, zomwe ndi: zoumba zogwira ntchito, zinthu zopepuka kwambiri, zinthu zosatha ntchito komanso zopangira zosungunulira. Pa siteji iyi, silicon carbide roughage ikhoza kuperekedwa m'njira zambiri, zomwe sizinthu zamakono kwambiri, ndipo kugwiritsa ntchito ufa wa nano-silicon carbide wokhala ndi zinthu zambiri zasayansi ndi ukadaulo sikungatheke kubweretsa zotsatirapo zake pakapita nthawi.
(3) galasi limodzi loyera kwambiri, loyenera kupanga zipangizo za semiconductor, komanso kupanga ulusi wa mankhwala a silicon carbide.
Kukula kwa ntchito: Kwa ma cell a photovoltaic a mamita 3-12, ma cell a photovoltaic, potassium arsenide, quartz resonators ndi zina zodulira mzere. Makampani opanga ma solar photovoltaic, makampani opanga ma semiconductor, piezoelectric crystal industry chain engineering project raw material processing.
Zifukwa za kapangidwe ka silicon carbide yogwira ntchito
Muyezo wokwera kwambiri komanso kutentha kwambiri womwe umapangidwa mkati mwa dziko lapansi umapopedwa kuchokera pansi ndi lava. Monga Thailand, Australia, Shandong ku China, United States ndi mayiko ena. Jade yachitsulo imapangidwa ndi kusintha kwa kukhudza. Monga Myanmar, Kashmir, Anhui ku China ndi madera ena. Ma rubi padziko lonse lapansi makamaka amachokera ku malo oyika. Ndi kudzera mumitundu yosiyanasiyana ya emeralds yoyambirira yachilengedwe, miyala yamtengo wapatali yabuluu ndi kukokoloka kwa nthaka, kuphatikiza kwa zinthu zomwe zimasungunuka silicon carbide ndi miyala yachilengedwe ya silicon, carbon, slag yamatabwa, mchere wamakampani monga zopangira zopangidwa, mu ng'anjo yotenthetsera yamagetsi, kutentha komwe kumawonetsedwa. Kuwonjezera kwa slag yamatabwa ndikupanga chidutswa chaching'ono cha zinthu zosakanikirana pa kutentha kwakukulu kuti apange kapangidwe ka ma porous, komwe kumathandiza kuwonetsa thupi lalikulu la nthunzi ndi kusakhazikika komwe kungachotsedwe, kupewa ngozi zophulika, chifukwa cha kupanga tani imodzi ya silicon carbide, kumatha kupanga pafupifupi 1.4t ya carbon monoxide (CO2). Udindo wa mchere wamakampani (NaCl) ndi wothandiza kuchotsa aluminium oxide, mankhwala ndi zotsalira zina muzinthuzo.
