Teeb duab nrau
Qhov no hom graphite crucible yog tshwj xeeb uas siv rau txhuas txheej zaj duab xis ntau lawm hauv tshuab nqus tsev. Qhov ua tau zoo ntawm graphite crucible yuav zoo heev rau cov yeeb yaj kiab zoo thiab cov nqi tsim khoom. Lub tshuab nqus tsev evaporation aluminium txheej txheem txheej txheem yog nyob rau hauv txheej nqus ntawm lub tshuab nqus tsev rau txheej txhuas txheej mus rau cov zaj duab xis txheej ua ib txheej zaj duab xis. Xws li substrates li BOPET, BONY, BOPP, PE, PVC, ncaj qha kev hloov pauv hloov txheej txheem feem ntau thov. Lub tshuab nqus evaporation txhuas txheej txheem txheej txheem yuav tsum muaj qhov zoo siab graphite crucible, thiab peb muaj peev xwm ruaj khov thiab ua tau zoo.

Graphite muaj kev
Graphite xav tau muab faib ua suab-raws li graphite felt, polyacrylonitrile-based (PAN-based) graphite muaj kev xav, thiab viscose-based graphite muaj kev xav vim qhov sib txawv xaiv ntawm thawj felts. Lub hom phiaj tseem ceeb yog siv los ua kev tiv thaiv tshav kub thiab cov cua kub rwb thaiv tsev rau cov monocrystalline silicon smelting qhov cub. Hauv kev lag luam chemical, nws tuaj yeem raug siv los ua cov khoom siv lim rau cov tshuaj pleev xim rau cov tshuaj lom neeg lub cev.
Xav tias carbon muaj xws li graphite tom qab kho nyob rau qhov kub ntawm ntau tshaj 2000 ℃ hauv qab nqus lossis nqus cua. Cov pa roj carbon ntsiab lus yog siab dua qhov ntawm carbon carbon, ncav cuag ntau dua 99%. Qhov kawg ntawm 1960s, graphite xav tau twb muaj nyob hauv lub ntiaj teb. Graphite xav tau muab faib ua suab-raws, polyacrylonitrile-based graphite muaj kev xav thiab viscose-based graphite xav vim qhov xaiv sib txawv ntawm cov thawj xav.
