Katundu wa recrystallized silicon carbide
Recrystallized silicon carbide (R-SiC) ndi chinthu chochita bwino kwambiri chokhala ndi kuuma kwachiwiri kwa diamondi, chomwe chimapangidwa pa kutentha kwambiri kuposa 2000 ℃. Imakhala ndi zinthu zambiri zabwino kwambiri za SiC, monga mphamvu ya kutentha kwambiri, kukana kwa dzimbiri, kukana kwa okosijeni kwabwino, kukana kwamphamvu kwamafuta ndi zina zotero.
● Makina abwino kwambiri. Recrystallized silicon carbide imakhala ndi mphamvu zambiri komanso kuuma kuposa mpweya wa kaboni, kukana kwakukulu, kumatha kusewera bwino m'malo otentha kwambiri, kumatha kusewera bwino pakanthawi kochepa. Kuonjezera apo, imakhalanso ndi kusinthasintha kwabwino ndipo sikuwonongeka mosavuta ndi kutambasula ndi kupindika, zomwe zimathandizira kwambiri ntchito yake.
● Kulephera kwa dzimbiri. Recrystallized pakachitsulo carbide ali mkulu dzimbiri kukana zosiyanasiyana TV, angalepheretse kukokoloka kwa zosiyanasiyana zowononga TV, akhoza kukhalabe mawotchi katundu wake kwa nthawi yaitali, ali adhesion amphamvu, kotero kuti ali ndi moyo wautali utumiki. Kuonjezera apo, ilinso ndi kukhazikika kwabwino kwa kutentha, imatha kusintha kusintha kwa kutentha, kusintha ntchito yake.
● Kuimba sikuchepa. Chifukwa njira ya sintering simachepa, palibe kupsinjika kotsalira komwe kungayambitse kusinthika kapena kusweka kwa chinthucho, ndipo magawo omwe ali ndi mawonekedwe ovuta komanso olondola kwambiri amatha kukonzekera.

VET Energy ndi omwe amapanga makonda opanga ma graphite ndi silicon carbide okhala ndi zokutira CVD, amatha kupereka magawo osiyanasiyana makonda a semiconductor ndi mafakitale a photovoltaic. Gulu lathu laukadaulo limachokera ku mabungwe apamwamba ofufuza zapakhomo, litha kukupatsirani mayankho aukadaulo.
Timapitirizabe kupanga njira zapamwamba zoperekera zipangizo zamakono, ndipo tapanga teknoloji yokhayo yovomerezeka, yomwe ingapangitse mgwirizano pakati pa zokutira ndi gawo lapansi kukhala lolimba komanso losavuta kusokoneza.
Takulandirani ndi manja awiri kuti mudzacheze fakitale yathu, tikambiranenso!
