Ingxenye Yokuqala: Umsebenzi Wezingxenye Zevacuum
Ngokomlando, ukuzalwa kwemishini ye-MBE kudlule inqubo ende.Ukuhwamuka kokuqala kwe-photochemical nezindlela zokuncibilika zingalandelelwa emuva kuma-1950s, kodwa lezi zindlela zinemikhawulo eminingi.Kamuva, i-epitaxy ye-molecular beam yaba khona futhi ngokushesha yaba indlela esetshenziswa kakhulu, futhi yanikeza namathuba amasha okuthuthukiswa nokwenza izingxenye ze-vacuum cavity.
Igumbi le-vacuum emishinini ye-MBE liyingxenye ebalulekile enganikeza indawo ephelele yokungena ukuze kuqinisekiswe ikhwalithi nokuzinza kokukhula kwezinto ezibonakalayo.Lawa makamelo e-vacuum adinga umoya ophezulu, ukubekezelela ukucindezela okuhle nokuzinza kokushisa, futhi akhiqizwa kusetshenziswa izinto ezikhethekile namasu.
Enye ingxenye ebalulekile i-vacuum valve, esebenza njengesivalo futhi ilawula ukucindezela kwe-vacuum emishinini ye-MBE.Ukuze kuqinisekiswe ukunemba okuphezulu nokuthembeka kwemishini, ama-vacuum valves kudingeka abe nokunemba okuhle kakhulu kokuvalwa nokushintsha, futhi enziwe kusetshenziswa izinto ezisezingeni eliphezulu kanye namasu okukhiqiza athuthukile.
Ingxenye Yesibili: Inqubo Yokukhiqiza Yezingxenye Zevacuum
Ukukhiqiza izingxenye zegumbi le-vacuum kudinga inqubo yokukhiqiza esezingeni eliphezulu.Izidingo zokukhetha impahla efanele, ubuchwepheshe bokucubungula, ukunemba kwe-dimensional kanye nokuqedwa kwendawo ziphezulu kakhulu.Ngesikhathi esifanayo, imishini ethuthukisiwe nobuchwepheshe kuyadingeka ukuze kuqinisekiswe ikhwalithi nokuzinza kokukhiqiza.Isibonelo, ukukhethwa kwezinto ezidingekayo kudinga ukucabangela izici ezihlukahlukene ezifana nezinga lokushisa eliphezulu, izinga lokushisa eliphansi kanye nokugqwala kwamakhemikhali, futhi ubuchwepheshe bokucubungula budinga ukuqinisekisa ukunemba kobukhulu kanye nokuqedwa kwendawo, okudinga imishini ethuthukisiwe nobuchwepheshe ukuze kuzuzwe.Ngesikhathi esifanayo, kunobunye ubuchwepheshe bokucubungula obunembayo obuphakeme, obufana nokucubungula i-laser, ukucutshungulwa kwe-electrochemical, njll., kanye nesayensi yezinto ezithuthukisiwe nobuchwepheshe, njengokufakwa komhwamuko wamakhemikhali, ukufakwa komhwamuko obonakalayo, njll.
Ngokuthuthuka okuqhubekayo kobuchwepheshe be-MBE, isidingo sezingxenye zegumbi le-vacuum siyanda.Akukhona nje kuphela ukuthi bangakwazi ukudlala indima ebalulekile ekukhuleni kwezinto ze-semiconductor, kodwa futhi zingasetshenziswa kwezinye izinhlelo zokusebenza, njengokwenziwa kwezingxenye eziphezulu ze-optical, izinto ze-semiconductor, njll. Emkhakheni we-biomedicine, ubuchwepheshe bokukhula kwezinto ezibonakalayo. ingasetshenziswa ukwenza izicubu zokwenziwa, ukulungisa ukukhubazeka kwezicubu, njll., futhi inamathemba okusebenza abanzi.
Ngaphezu kokuhlukahluka kwezinkambu zokufaka isicelo, izinzuzo zobuchwepheshe bokukhula kwempahla zihlanganisa inqubo elula yokulungiselela, ukulawulwa okuqinile, izindleko eziphansi, isivinini sokulungiselela okusheshayo nokunye.Lezi zinzuzo zenza ubuchwepheshe bokukhula kwezinto buye bukhathazeke futhi busetshenziswe kabanzi.
Ingxenye Yesithathu: Inselele yobuchwepheshe bokukhula kwezinto ezibonakalayo
Kodwa-ke, ubuchwepheshe bokukhula kwezinto ezibonakalayo buphinde bubhekane nezinselelo ezithile ohlelweni lokufaka isicelo.Okokuqala, inqubo yokukhula yezinto ngokuvamile ithintwa izici eziningi, njengezinga lokushisa, ingcindezi, umkhathi, ukugxiliswa kwe-reactant, njll. Izinguquko kulezi zici zizoba nomthelela obalulekile kukhwalithi yokukhula kwezinto, ngakho ukulawula okunembile kuyadingeka. .Okwesibili, izinkinga ezinjengokukhula okungalingani kanye nokukhubazeka kwekristalu kungenzeka ngesikhathi senqubo yokukhula kwezinto.Lezi zinkinga zidinga ukukhonjwa futhi zixazululwe ngesikhathi ngesikhathi sokukhula, ngaphandle kwalokho zizoba nomthelela omubi ekusebenzeni kwempahla.
Ngaphezu kokuhlukahluka kwezinkambu zokufaka isicelo, izinzuzo zobuchwepheshe bokukhula kwempahla zihlanganisa inqubo elula yokulungiselela, ukulawulwa okuqinile, izindleko eziphansi, isivinini sokulungiselela okusheshayo nokunye.Lezi zinzuzo zenza ubuchwepheshe bokukhula kwezinto buye bukhathazeke futhi busetshenziswe kabanzi.
Amakhono Womshini Wezingxenye Zevacuum ye-GPM:
I-GPM inolwazi oluningi ku-CNC machining yezingxenye ze-vacuum.Sisebenze namakhasimende ezimbonini eziningi, okuhlanganisa i-semiconductor, imishini yezokwelapha, njll., futhi sizibophezele ekunikezeni amakhasimende ngekhwalithi ephezulu, izinsizakalo zemishini ezinembile.Samukela uhlelo oluqinile lokuphatha ikhwalithi ukuze siqinisekise ukuthi ingxenye ngayinye ihlangabezana nokulindelwe ngamakhasimende kanye namazinga.
