Imikhiqizo ye-graphite yokuhwamuka kwe-aluminium

Umsizi we-graphite
Lolu hlobo lwe-graphite crucible lusetshenziselwa ngokukhethekile ukukhiqizwa kwefilimu e-aluminium ngaphansi kwesimo se-vacuum. Ikhwalithi ye-graphite crucible izothinta kakhulu ikhwalithi yefilimu nezindleko zokukhiqiza. Umshini wokuhwamuka kwe-aluminium wokumisa inqubo ngaphansi kwesimo se-vacuum sokufaka i-aluminium kuma-substrates efilimu ukwakha ifilimu elihlanganisiwe. Njengama-substrates njenge-BOPET, i-BONY, i-BOPP, i-PE, i-PVC, inqubo eqondile yokuhambisa ukuhwamuka ivame ukusetshenziswa. Inqubo yokugcwala kwe-aluminium yokuhwamuka idinga izinga eliphezulu le-graphite crucible, futhi siyakwazi ukuhambisa okuzinzile nekhwalithi.

Graphite wezwa
I-graphite izwakala ihlukaniswe nge-pitch-based graphite wezwa, i-polyacrylonitrile-based (PAN-based) graphite yezwa, kanye ne-viscose-based graphite yezwa ngenxa yokukhetha okwehlukile kwama-original felts. Inhloso enkulu ukuthi isetshenziswe njengokulondolozwa kokushisa nezinto zokwakha ukushisa kwamakhemikhali e-monocrystalline silicon smelting. Embonini yamakhemikhali, ingasetshenziswa njengezinto zokuhlunga zama-reagents amakhemikhali abola kakhulu.
I-Carbon izwa ukuthi i-graphite izwakale ngemuva kokuphathwa ezingeni lokushisa eliphakeme elingaphezu kuka-2000 ℃ ngaphansi komshini noma emoyeni. Okuqukethwe kwekhabhoni kuphakeme kunalokho okuzwayo kwekhabhoni, kufinyelela ngaphezu kuka-99%. Ekupheleni kweminyaka yama-1960, i-graphite yazizwa isivele itholakala emhlabeni. I-graphite izwakala ihlukaniswe nge-pitch-based, i-polyacrylonitrile-based graphite yezwa futhi i-viscose-based graphite yezwa ngenxa yokukhethwa okuhlukile kwemizwa yokuqala.
