Kuyambitsa ndi kugwiritsa ntchito mankhwala a black silicon carbide
Kabide wakuda wa silikoni(yofupikitsidwa ngati black silicon carbide) ndi chinthu chopangidwa chosakhala chachitsulo chopangidwa ndi mchenga wa quartz ndi petroleum coke ngati zinthu zazikulu zopangira ndipo chimasungunuka kutentha kwambiri mu uvuni wokana. Chimawoneka ngati chakuda kapena chakuda chakuda, cholimba kwambiri, kutentha kwabwino komanso kukhazikika kwa mankhwala. Ndi chinthu chabwino kwambiri chopangira mafakitale ndipo chimagwiritsidwa ntchito kwambiri mu zinthu zopangira zinthu zopopera, zinthu zotsutsa, zitsulo, zoumbaumba, zamagetsi ndi zina.
Ⅰ. Makhalidwe a ntchito ya black silicon carbide
Kuuma kwa Mohskabide wakuda wa silikoniIli ndi kutentha kokwana 9.2, yachiwiri pambuyo pa diamondi ndi cubic boron nitride, ndipo ili ndi mphamvu yolimba kwambiri yolimbana ndi kutopa komanso kukana kugwedezeka. Malo ake osungunuka ndi pafupifupi 2700°C, ndipo imatha kusunga kukhazikika kwa kapangidwe kake m'malo otentha kwambiri ndipo sikophweka kuwola kapena kusokoneza. Kuphatikiza apo, ili ndi kutentha kwabwino komanso kutentha kochepa, ndipo imawonetsabe kukhazikika kwa kutentha kwambiri pansi pa kutentha kwakukulu komanso kupsinjika kwakukulu.
Ponena za mphamvu zake zamagetsi, black silicon carbide ili ndi kukana dzimbiri kwa ma acid ndi alkali, ndipo ndi yoyenera kugwiritsidwa ntchito m'mafakitale m'malo ovuta. Mphamvu yake yoyendetsa bwino mpweya imapangitsanso kuti ikhale chinthu china chogwiritsira ntchito zipangizo zina zotenthetsera zamagetsi ndi minda ya semiconductor.
Ⅱ. Mafomu akuluakulu azinthu ndi kufotokozera
Kabide wakuda wa silikoni angapangidwe m'njira zosiyanasiyana malinga ndi kukula ndi ntchito zosiyanasiyana za tinthu:
Zipangizo zomangira: makhiristo akuluakulu akasungunuka, nthawi zambiri amagwiritsidwa ntchito pokonzanso kapena ngati zowonjezera zachitsulo;
Mchenga wopyapyala (mchenga wa F/mchenga wa P): umagwiritsidwa ntchito popanga mawilo opukusira, zopukusira mchenga, sandpaper, ndi zina zotero;
Ufa waung'ono (W, D): wogwiritsidwa ntchito popera, kupukuta, kupukuta ndi ceramic sintering, ndi zina zotero;
Ufa waung'ono wa nano-level: wogwiritsidwa ntchito popanga zinthu zamagetsi zapamwamba kwambiri, zinthu zophatikizana ndi kutentha, ndi zina zotero.
Kukula kwa tinthu tating'onoting'ono kumasiyana kuyambira F16 mpaka F1200, ndipo kukula kwa tinthu tating'onoting'ono ta ufa wochepa kumatha kufika pamlingo wa nanometer, womwe ungasinthidwe malinga ndi zofunikira zaukadaulo m'magawo osiyanasiyana ogwiritsira ntchito.
Ⅲ. Main ntchito m'madera akuda silikoni carbide
1. Zida zopukutira ndi zopukutira
Ma abrasives ndi malo achikhalidwe komanso ogwiritsidwa ntchito kwambiri a black silicon carbide. Pogwiritsa ntchito kuuma kwake kwakukulu komanso luso lake lodzinola lokha, black silicon carbide ingagwiritsidwe ntchito popanga zinthu zosiyanasiyana zokwawa, monga mawilo opukusira, ma disc odulira, sandpaper, mitu yopukusira, ma phala opukusira, ndi zina zotero, zomwe ndizoyenera kupukusira ndi kukonza zinthu monga chitsulo chosungunuka, chitsulo, zitsulo zopanda ferrous, ziwiya zadothi, magalasi, quartz, ndi simenti.
Ubwino wake ndi liwiro lopera mofulumira, si losavuta kutsekeka, komanso luso lokonza bwino. Limagwiritsidwa ntchito kwambiri pokonza zitsulo, kupanga makina, kukongoletsa nyumba ndi mafakitale ena.
2. Zipangizo zopopera mpweya
Chifukwa cha kukhazikika kwake kutentha kwambiri komanso kukana dzimbiri, black silicon carbide imagwiritsidwa ntchito kwambiri popanga zinthu zotentha kwambiri. Itha kupangidwa kukhala njerwa za silicon carbide, zipilala za ng'anjo, zophimbira, machubu oteteza thermocouple, zida za uvuni, ma nozzles, njerwa za tuyere, ndi zina zotero, ndipo imagwiritsidwa ntchito kwambiri m'mafakitale otentha kwambiri monga zitsulo, zitsulo zopanda ferrous, magetsi, magalasi, simenti, ndi zina zotero, kuti iwonjezere nthawi ya zida ndikuwonjezera chitetezo cha ntchito.
Kuphatikiza apo, zinthu za silicon carbide zimakhala ndi mphamvu zabwino zoteteza ku zinthu zowononga chilengedwe m'mlengalenga wotentha kwambiri ndipo ndizoyenera kugwiritsidwa ntchito m'zigawo zofunika kwambiri za zitofu zotentha, zitofu zophulika ndi zida zina.
3. Makampani opanga zitsulo
Mu njira zopangira zitsulo monga kupanga zitsulo ndi kuponyera, black silicon carbide ingagwiritsidwe ntchito ngati deoxidizer, chotenthetsera komanso chobwezeretsanso. Chifukwa cha kuchuluka kwa kaboni komanso kutulutsa kutentha mwachangu, imatha kusintha bwino ntchito yosungunula ndikukweza ubwino wa chitsulo chosungunuka. Nthawi yomweyo, imathanso kuchepetsa kuchuluka kwa zodetsa mu njira yosungunula ndikuchita gawo loyeretsa chitsulo chosungunuka.
Mafakitale ena achitsulo amawonjezeranso gawo lina la silicon carbide kuti asinthe kapangidwe kake pakusungunula chitsulo chopangidwa ndi chitsulo chopangidwa ndi ductile kuti asunge ndalama ndikuwonjezera magwiridwe antchito a castings.
4. Zida zadothi ndi zipangizo zamagetsi
Kabide wakuda wa silicon ndi chinthu chofunikira kwambiri pa zinthu zogwirira ntchito za ceramic. Ingagwiritsidwe ntchito pokonzekera zinthu zomangira, zinthu zomangira zosatha, zinthu zomangira zotenthetsera kutentha, ndi zina zotero, ndipo ili ndi mwayi waukulu m'magawo a zamagetsi, makampani opanga mankhwala, makina, ndi zina zotero. Ili ndi mphamvu yabwino kwambiri yotenthetsera kutentha, yokhala ndi mphamvu yotenthetsera kutentha ya 120 W/m·K, ndipo nthawi zambiri imagwiritsidwa ntchito pazinthu zotenthetsera kutentha, zinthu zolumikizira kutentha ndi zinthu zotenthetsera kutentha za LED.
Kuphatikiza apo, silicon carbide yalowa pang'onopang'ono m'munda wa ma semiconductor amphamvu ndipo yakhala chinthu chofunikira kwambiri pazida zotentha kwambiri komanso zamagetsi ambiri. Ngakhale kuti kuyera kwa silicon carbide yakuda kuli kotsika pang'ono kuposa kwa silicon carbide yobiriwira, imagwiritsidwanso ntchito pazinthu zina zamagetsi zamagetsi zapakati komanso zochepa.
5. Makampani opanga mphamvu zamagetsi ndi magetsi atsopano
Ufa wakuda wa silicon carbide umagwiritsidwa ntchito kwambiri podula ma wafer a silicon mumakampani opanga ma photovoltaic. Popeza ndi wokhwimitsa kwambiri pakudula waya wa diamondi, uli ndi ubwino wolimba kwambiri, wolimba.kudulamphamvu, kutayika kochepa, ndi malo odulira osalala, zomwe zimathandiza kukonza bwino kudula ndi kukolola kwa ma wafer a silicon ndikuchepetsa kutayika kwa ma wafer ndi ndalama zopangira.
Ndi chitukuko chopitilira cha mphamvu zatsopano ndi ukadaulo watsopano, silicon carbide ikupangidwanso m'magawo atsopano monga zowonjezera za lithiamu batire negative electrode ndi zonyamulira za ceramic membrane.
Ⅳ. Chidule ndi Kawonedwe
Carbide yakuda ya silicon imagwira ntchito yofunika kwambiri m'mafakitale ambiri chifukwa cha mphamvu zake zabwino kwambiri zamakanika, kutentha komanso mankhwala. Ndi kupita patsogolo kosalekeza kwa ukadaulo wopanga zinthu, kuwongolera kukula kwa tinthu tating'onoting'ono ta zinthu, kuyeretsa bwino komanso kukulitsa kosalekeza kwa minda yogwiritsira ntchito, carbide yakuda ya silicon ikupita patsogolo kuti igwire bwino ntchito komanso molondola.
M'tsogolomu, chifukwa cha kukwera mofulumira kwa mafakitale monga mphamvu zatsopano, ziwiya zamagetsi, zinthu zapamwambakupukusa ndi kupanga mwanzeru, black silicon carbide idzakhala ndi gawo lofunika kwambiri pakupanga zinthu zapamwamba kwambiri ndipo idzakhala gawo lofunika kwambiri la makina apamwamba aukadaulo.
