Isici sokushisa sikagesi esingu-2000 degree sikagesi: isici sokushisa se-graphite
Isici sokushisa sikagesi esingu-2000 degree sikagesi: isici sokushisa se-graphite
Isici sokushisa sika-2000 degree sikagesi sebhokisi somlilo ngokuvamile senziwe nge-graphite, molybdenum noma i-MoSi2. Izakhi ze-graphite zivame ukusetshenziswa njengezinto zokufudumeza ezifuleni ze-vacuum ezinezinga lokushisa eliphezulu, ezidlala indima ebalulekile ekudumeni nasekusetshenzisweni kweziko lokushisa eliphezulu lokumelana ne-vacuum kanye neziko lokushisa eliphezulu elivikelayo. Isici sokushisisa segraphite singashisisa kangakanani? Isici sokushisa se-graphite sisetshenziswa ku-vacuum ekushiseni okungama-2200℃, futhi singafinyelela ku-3000℃ emkhathini owehlisayo noma endaweni engasebenzi.
Isici sokushisa se-graphite: Isici sokushisa se-graphite siyinto yokushisisa ene-graphite impahla njengomzimba wokushisisa. I-graphite inezici zokumelana nezinga lokushisa eliphezulu, ukunwebeka okuphansi kokushisa, nokumelana nokushaqeka okuqinile kokushisa. Amandla ayo okusebenza akhula ngokukhuphuka kwezinga lokushisa elichotshozwayo libe ngaphansi kuka-2500°C. Cishe i-1700°C ihamba phambili, idlula wonke ama-oxide nezinsimbi. I-graphite inephuzu eliphezulu lokuncibilika kanye nomfutho we-vapor ophansi. Umkhathi wesithando se-vacuum uqukethe ukugcwala okuphansi kwekhabhoni, okuzosabela nomoya-mpilo nomhwamuko wamanzi kugesi esele ukuze kukhiqizwe umphumela wokuhlanza, okwenza lula kakhulu uhlelo lwe-vacuum nokunciphisa izindleko. Enqubweni yokukhiqiza yesithando somlilo, isici sokushisa esivame ukusetshenziselwa ukwelashwa kokushisa i-graphite, okuhlanganisa ukusekelwa kwayo kweziko, isikrini sokugcina ukushisa, ipuleti lokuxhuma, i-nati yokuxhuma, ipayipi yokukhipha umoya nokunye.
Ngokuthuthukiswa kwezinga lemishini yokwelapha ukushisa nokujula kwezidingo zenqubo, izidingo zokushisa zezithando ze-vacuum nazo ziya ngokuya zikhuphuka. Izinto zokushisisa zendabuko ezifana nezinti ze-silicon carbide nezinduku ze-silicon molybdenum azisakwazi ukuhlangabezana nezimfuneko zokushisa okuphezulu, futhi izinti ze-graphite sezivele njengoba izikhathi zidinga .
