Kuyambitsa mankhwala ndi kugwiritsa ntchito Black silicon carbide
Black silicon carbide(yofupikitsidwa ngati black silicon carbide) ndi chinthu chopanga chosapanga chitsulo chopangidwa ndi mchenga wa quartz ndi petroleum coke monga zida zazikulu zopangira ndipo amasungunuka kutentha kwambiri mung'anjo yolimbana ndi moto. Ili ndi mawonekedwe akuda-imvi kapena mdima wakuda, kuuma kwambiri, kutentha kwabwino komanso kukhazikika kwamankhwala. Ndi zida zabwino kwambiri zamafakitale ndipo zimagwiritsidwa ntchito kwambiri popangira ma abrasives, zida zotsutsa, zitsulo, zoumba, zamagetsi ndi zina.
Ⅰ. Zochita za Black silicon carbide
Kuuma kwa Mohs kwawakuda silicon carbidendi wokwera kwambiri mpaka 9.2, wachiwiri pambuyo pa diamondi ndi kiyubiki boron nitride, ndipo ali ndi kukana kwamphamvu kwambiri komanso kukana mphamvu. Malo ake osungunuka ndi pafupifupi 2700 ° C, ndipo amatha kukhala okhazikika m'malo otentha kwambiri ndipo sizovuta kuwola kapena kupunduka. Kuphatikiza apo, imakhala ndi ma conductivity abwino amafuta komanso kutsika kocheperako kowonjezera kwamafuta, ndipo ikuwonetsabe kukhazikika kwamphamvu kwamatenthedwe kutentha kwambiri komanso kupanikizika kwambiri.
Pankhani yamankhwala, silicon carbide yakuda imakhala ndi kukana kwa dzimbiri kwa ma acid ndi alkalis, ndipo ndiyoyenera kugwiritsidwa ntchito m'mafakitale m'malo ovuta. Kuwongolera kwake kumapangitsanso kukhala chinthu china chazinthu zina zotenthetsera magetsi ndi minda ya semiconductor.
Ⅱ. Main mankhwala mafomu ndi specifications
Black silicon carbide ikhoza kupangidwa m'njira zosiyanasiyana malinga ndi kukula kwake ndi ntchito:
Zida zotchinga: makhiristo akulu akasungunuka, omwe amagwiritsidwa ntchito nthawi zambiri kukonzanso kapena ngati zowonjezera zitsulo;
Mchenga wa granular (mchenga wa F / P): amagwiritsidwa ntchito popanga mawilo opera, ma abrasives opangira mchenga, sandpaper, etc.;
Micro ufa (W, D mndandanda): ntchito kopitilira muyeso akupera, kupukuta, ceramic sintering, etc.;
Nano-level yaying'ono ufa: yogwiritsidwa ntchito pazida zapamwamba zamagetsi zamagetsi, zida zopangira matenthedwe, etc.
The tinthu kukula ranges F16 kuti F1200, ndi tinthu kukula kwa ufa yaying'ono akhoza kufika nanometer mlingo, amene akhoza makonda malinga ndi luso amafuna minda zosiyanasiyana ntchito.
Ⅲ. Malo ogwiritsira ntchito kwambiri a black silicon carbide
1. Abrasives ndi zida zopera
Ma Abrasives ndi malo omwe amagwiritsidwa ntchito kwambiri komanso omwe amagwiritsidwa ntchito kwambiri ndi silicon carbide yakuda. Pogwiritsa ntchito kuuma kwake kwakukulu komanso kudzipangira okha, silicon carbide yakuda ingagwiritsidwe ntchito popanga zinthu zosiyanasiyana zowononga, monga mawilo opera, ma disks odula, sandpaper, mitu yopera, phala lopera, ndi zina zotero, zomwe zili zoyenera pogaya ndi kukonza zinthu monga chitsulo, zitsulo, zitsulo zopanda chitsulo, zoumba, galasi, zitsulo zopangidwa ndi simenti.
ubwino wake ndi kudya akupera liwiro, osati zosavuta kutseka, ndi mkulu processing dzuwa. Amagwiritsidwa ntchito kwambiri pokonza zitsulo, kupanga makina, kukongoletsa nyumba ndi mafakitale ena.
2. Refractory zipangizo
Chifukwa cha kukhazikika kwake kwa kutentha komanso kukana kwa dzimbiri, silicon carbide yakuda imagwiritsidwa ntchito kwambiri popanga zida zowotcha kwambiri. Ikhoza kupangidwa kukhala njerwa za silicon carbide, ng'anjo ya ng'anjo, crucibles, machubu otetezera thermocouple, zida zamoto, nozzles, njerwa za tuyere, ndi zina zotero, ndipo zimagwiritsidwa ntchito kwambiri m'mafakitale omwe amatentha kwambiri monga zitsulo, zitsulo zopanda chitsulo, magetsi, galasi, simenti, ndi zina zotero, kuti apititse patsogolo moyo wa zida zachitetezo.
Kuphatikiza apo, zida za silicon carbide zili ndi zinthu zabwino za antioxidant m'malo otentha kwambiri oxidizing atmospheres ndipo ndizoyenera kugwiritsidwa ntchito m'magawo ofunikira a ng'anjo zotentha zotentha, ng'anjo zophulika ndi zida zina.
3. Makampani opanga zitsulo
Muzitsulo zazitsulo monga kupanga zitsulo ndi kuponyera, silicon carbide yakuda ingagwiritsidwe ntchito ngati deoxidizer, wothandizila kutentha ndi recarburizer. Chifukwa chokhala ndi mpweya wambiri komanso kutentha kwachangu, imatha kupititsa patsogolo bwino kusungunula ndikuwongolera chitsulo chosungunuka. Panthawi imodzimodziyo, imathanso kuchepetsa zonyansa muzitsulo zosungunula ndikuthandizira kuyeretsa zitsulo zosungunuka.
Mphero zina zazitsulo zimawonjezeranso gawo lina la silicon carbide kuti asinthe momwe amasungunula chitsulo chosungunuka ndi chitsulo cha ductile kuti apulumutse ndalama ndikuwongolera magwiridwe antchito.
4. Ceramics ndi zipangizo zamagetsi
Black silicon carbide ndiyofunikanso zopangira zopangira zoumba. Ikhoza kugwiritsidwa ntchito pokonzekera zoumba, zoumba zosagwira ntchito, zowonongeka zowonongeka, ndi zina zotero, ndipo zimakhala ndi ziyembekezo zazikulu pazochitika zamagetsi, mafakitale a mankhwala, makina, ndi zina zotero. Ili ndi makonzedwe abwino kwambiri a matenthedwe, okhala ndi matenthedwe a ku 120 W / m · K, ndipo amagwiritsidwa ntchito nthawi zambiri mu zipangizo zopangira matenthedwe, mawonekedwe a kutentha kwa LED ndi kutentha kwa disrsipa.
Kuphatikiza apo, silicon carbide yalowa pang'onopang'ono m'munda wamagetsi opangira magetsi ndikukhala zinthu zofunika kwambiri pazida zotentha kwambiri komanso zamphamvu kwambiri. Ngakhale kuyera kwa silicon carbide yakuda ndi yotsika pang'ono kuposa ya green silicon carbide, imagwiritsidwanso ntchito pazinthu zina zamagetsi zapakatikati komanso zotsika.
5. Mafakitale a Photovoltaic ndi mphamvu zatsopano
Black silicon carbide ufa amagwiritsidwa ntchito kwambiri podula zowotcha za silicon mumakampani a photovoltaic. Monga abrasive mu njira yodula waya ya diamondi, ili ndi ubwino wa kuuma kwakukulu, kolimbakudulamphamvu, kutayika pang'ono, komanso kudula kosalala, komwe kumathandizira kukonza magwiridwe antchito ndi zokolola za zowotcha za silicon ndikuchepetsa kutayika kwa mkate ndi mtengo wopanga.
Ndi kukula kosalekeza kwa mphamvu zatsopano ndi matekinoloje atsopano azinthu, silicon carbide ikupangidwiranso magawo omwe akubwera monga lithiamu batire negative electrode additives ndi ceramic membrane zonyamulira.
Ⅳ. Chidule ndi Outlook
Black silicon carbide imagwira ntchito yosasinthika m'mafakitale ambiri ndi makina ake abwino kwambiri, matenthedwe ndi mankhwala. Ndi kupita patsogolo kosalekeza kwa ukadaulo wopanga, kuwongolera kukula kwa tinthu, kuyenga koyera komanso kukulitsa minda yogwiritsira ntchito, silicon carbide yakuda ikukula kwambiri komanso yolondola kwambiri.
M'tsogolomu, ndikukwera mofulumira kwa mafakitale monga mphamvu zatsopano, zoumba zamagetsi, zapamwambakugaya komanso kupanga mwanzeru, silicon carbide yakuda idzagwira ntchito yofunika kwambiri pakupanga zinthu zapamwamba kwambiri ndikukhala gawo lalikulu laukadaulo wapamwamba kwambiri.
