Boti Lopangidwanso ndi Silicon Carbide Wafer Ndi CVD Coating

Kufotokozera Kwachidule:

VET Energy Recrystallized Silicon Carbide Wafer Boat ndi chinthu chochita bwino kwambiri chomwe chimapangidwa kuti chizipereka magwiridwe antchito osasinthika komanso odalirika kwa nthawi yayitali. Ili ndi kukana kwabwino kwambiri kwa kutentha komanso kufananizidwa kwamafuta, kuyera kwakukulu, kukana kukokoloka, kupangitsa kuti ikhale yankho labwino kwambiri pakukonza mapulogalamu opaka utoto.

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.

Zabwino kwambiri

Mbiri ya VET Energy ndiwopanga weniweni wa makonda graphite ndi silicon carbide mankhwala ndi CVD zokutira,akhoza kuperekazosiyanasiyanamagawo makonda a semiconductor ndi photovoltaic makampani. OGulu laukadaulo la ur limachokera ku mabungwe apamwamba ofufuza zapakhomo, limatha kupereka mayankho aukadaulozanu.

Timapitiriza kupanga njira zapamwamba kuti tipereke zipangizo zamakono,ndiapanga ukadaulo wapatent, womwe ungapangitse kulumikizana pakati pa zokutira ndi gawo lapansi kukhala lolimba komanso kuti lisasokonezeke.
