Kuyini i-graphite crucible?
Isitsha sokubethela se-graphiteiyingxenye ebalulekile yezimboni, esetshenziswa kabanzi emikhakheni eyahlukene yezimboni, njenge-metallurgy, i-casting, imishini, i-chemistry, i-semiconductor, njll. Iyindlela yokudlulisa ukushisa efanele kanye ne-conductor, engakwazi ukuqhuba ukushisa nogesi ngempumelelo enkambisweni yokukhiqiza futhi ingamukela inani elikhulu lezingxenye. Ekukhiqizeni i-semiconductor, i-graphite crucible idlala indima ebalulekile futhi ingenye yemishini ebalulekile ekukhiqizeni i-semiconductor.
Yiziphi izinhlobo nezici zezingcezu ze-graphite?
Kunezinhlobo eziningi zezitsha ze-graphite, futhi kunezitsha ze-graphite ezifanelekela izikhathi ezahlukahlukene, njengezitsha ze-crucible eziyindilinga, izitsha ze-crucible eziyisikwele, izitsha ze-crucible ezihlanganisiwe, njll. Izitsha ze-graphite ezahlukene zinezici ezahlukene, kodwa zonke zinokudluliswa kokushisa okuhle kakhulu kanye nokuqhuba kukagesi, okungathuthukisa ngempumelelo ukusebenza kahle kwemishini.
Izitsha ze-graphite nazo zingahlukaniswa ngokuningiliziwe ngokwezindawo ezahlukene zokusetshenziswa:
1. Isitsha esivamile sokubumba: sifanelekela ukuncibilikisa, ukufudumeza nokugcina ukushisa kwezinsimbi ezijwayelekile kanye nama-alloy.
2. I-crucible yokushisa okuphezulu: ifanelekela ukuncibilikisa izinsimbi ezingaphikisi kanye nama-alloy emazingeni okushisa aphezulu, njenge-tungsten, i-molybdenum, i-tantalum, njll.
3. I-Synthesis crucible: esetshenziselwa ukuhlanganisa nokulungiselela izinto ezihlanzekile kakhulu, njengezinto ze-semiconductor, izinto ze-ceramic, njll.
4. I-vacuum crucible: ifanele ukufudumeza nokuncibilikisa endaweni ye-vacuum, esetshenziswa kakhulu ekulungiseleleni izinto ezikhethekile kanye nokuncibilikisa izinsimbi ezihlanzekile kakhulu.
Izinto zokukhiqiza ze-graphite crucible zinokumelana okuhle nokushisa okuphezulu kanye nokuqina kwamakhemikhali. Zingasetshenziswa ekushiseni okuphezulu ngaphandle kokuguquka noma ukulimala ngenxa yokushisa okuphezulu. Ngesikhathi esifanayo, i-graphite crucible nayo inokumelana okuhle kakhulu nokugqwala futhi ingamelana ngempumelelo nokuguguleka kwezinto ezahlukahlukene zamakhemikhali, ngaleyo ndlela iqinisekise ikhwalithi yokukhiqiza yamadivayisi e-semiconductor.
Yiziphi izinhlelo zokusebenza eziyinhloko ze-graphite crucibles ku-semiconductor?
Enqubweni yokukhiqiza ye-semiconductor,izitsha ze-graphitezisetshenziswa kakhulu ukuthwala nokuvikela izingxenye ze-semiconductor, futhi zingadlulisa ukushisa kanye nomsinga ngempumelelo. Ngesibambo kanye nama-bracket amathathu aqinile phansi kwe-graphite crucible, inani elikhulu lezingxenye ze-semiconductor lingafakwa ku-graphite crucible ukuze zixhumane kahle ne-graphite crucible, ngaleyo ndlela zidlulise ukushisa kanye nomsinga ngempumelelo.
Ngaphezu kwalokho, i-graphite crucible ingasetshenziswa futhi njengomqhubi ofanele wokushisa nogesi. Ngenxa yokuqhuba kwayo ukushisa okuphezulu kanye nokuqhuba kukagesi, i-graphite crucible ingaqhuba ukushisa kanye nomsinga kusuka ngaphandle kwemishini kuya ezingxenyeni ze-semiconductor ngaphakathi kwe-graphite crucible, ngaleyo ndlela ifudumale ngempumelelo izingxenye ze-semiconductor futhi ilawule umsinga.
Ngaphezu kwalokho, i-graphite crucible ingasebenza futhi njengomqhubi wokushisa nogesi ofanele, ongamukela inani elikhulu lezingxenye ze-semiconductor, okuvumela imishini ukuthi icubungule izingxenye eziningi ngesikhathi esisodwa, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokucubungula kwemishini.
Yiziphi izinhlelo zokusebenza ze-graphite crucible embonini?
Ukuqina kwezinga lokushisa eliphezulu kanye nokuqina kwamakhemikhali kwe-graphite crucible kuyenza ikwazi ukumelana nokuncibilika kwensimbi emazingeni okushisa aphezulu, okuqinisekisa ikhwalithi kanye nokuqina kwezinto ezincibilikisiwe. Ngakho-ke, ingasetshenziswa ukulungiselela nokuncibilikisa izinto zensimbi ezahlukahlukene, njengethusi, i-aluminium, i-zinc, njll. Ngaphezu kwalokho, i-graphite crucible ingasetshenziswa futhi ukulungiselela nokuncibilikisa izinto ze-alloy.
Ngaphezu kwalokho, izitsha ze-graphite nazo zinokumelana okuhle nokugqwala. I-Graphite inamandla okugqwala ezintweni eziningi zamakhemikhali futhi ingamelana nokuguguleka kwezinto ezigqwala njenge-asidi, ama-alkali, kanye nezinyibilikisi. Ngakho-ke, izitsha ze-graphite zivame ukusetshenziselwa ukugcina, ukuphatha, nokuhlaziya izinto ezigqwala. Isibonelo, embonini yamakhemikhali, izitsha ze-graphite zingasetshenziswa ekuqoqeni amasampula, ekuncibilikiseni izinto, kanye nokugcina ama-reagents ane-asidi. Ekuhlanganiseni kwezinto eziphilayo, izitsha ze-graphite zingasetshenziswa ekwelapheni izinyibilikisi zokusabela kanye nama-catalyst, kanye nenqubo yokwenza izinto eziphilayo zibe yikristale nokomisa.
Ukufingqa
Ngaphezu kokusetshenziswa kwayo ekukhiqizweni kwe-semiconductor, izitsha ze-graphite nazo zingadlala indima ebalulekile ekusetshenzisweni kwensimbi, ekubunjweni, emishinini, ekhemistri nakwezinye izinkambu. Isibonelo, embonini yensimbi, izitsha ze-graphite zingasetshenziswa ukuncibilikisa nokucwengisisa izinto zensimbi; embonini yokuthunga, izitsha ze-graphite zingasetshenziswa ukuncibilikisa izinto zensimbi nokwenza imikhiqizo ehlukahlukene yensimbi; embonini yamakhemikhali, izitsha ze-graphite zingasetshenziswa njengezinto zokusabela noma izitsha zokusabela kwamakhemikhali. Ngakho-ke, inani lezitsha ze-graphite alibonakali kuphela emasimini okusetshenziswa kwazo, kodwa futhi nasendimeni yalo ebalulekile ekukhiqizweni kwezimboni. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, amathuba okusetshenziswa kwezitsha ze-graphite azoba banzi.
