Grafayithi ngokuyinyibilikisa
Olu hlobo grafayithi ngokuyinyibilikisa isetyenziselwa ngokukodwa imveliso aluminiyam camera umboniso phantsi imeko ezincamathelayo. Umgangatho we-graphite crucible uya kuchaphazela kakhulu umgangatho wefilimu kunye neendleko zokuvelisa. Umshini umphunga wealuminium yokwaleka yinkqubo ephantsi kwento yokuthambisa ukuze uthambe ialuminium kwimigca yefilimu yokwenza ifilimu edibeneyo. Ezifana nemicu esezantsi njenge-BOPET, BONY, BOPP, PE, PVC, inkqubo yokuhambisa umphunga ngqo ihlala isetyenziswa. Inkqubo yokuhambisa umphunga wealuminiyam ifuna umgangatho ophezulu wegraphite, kwaye siyakwazi ukuzinza kunye nomgangatho wokuhambisa.

Grafayithi waziva
I-graphite yaziva yahlulwe yarite-based graphite felt, polyacrylonitrile-based (PAN-based) graphite felt, and viscose-based graphite felt because of a different selection of original felts. Eyona njongo iphambili kufuneka isetyenziswe njengolondolozo lobushushu kunye nezinto zokubambisa ubushushu kwi-monocrystalline silicon smelting furnace. Kwimizi-mveliso yamachiza, inokusetyenziswa njengesixhobo sokucoca ulwelo lwe-reagents zamachiza ezonakalisayo.
Ikharbon yaziva igrafayithi yaziva emva kokuphathwa kubushushu obuphezulu obungaphezulu kwama-2000 ℃ phantsi komshini okanye emoyeni. Umxholo wekhabhoni uphezulu kunowecarbon aziva, ufikelela ngaphezulu kwama-99%. Ekupheleni kweminyaka yama-1960, i-graphite yaziva sele isele ikhona kwihlabathi. I-graphite yaziva yahlulwe yaya kususelwa kwi-pitch-based, i-polyacrylonitrile-based grafite yaziva kwaye i-viscose-based grafite yaziva ngenxa yokhetho olwahlukileyo lweemvakalelo zokuqala.
