izakhi ze-molybdenum heater Umumo ongu-U Intambo yokushisisa yomumo
Izakhi zokushisa ze-molybdenum ezimise okwe-W zenzelwe ukuhlinzeka indawo enkulu yokushisa, zizenze zifanelekele izinhlelo zokusebenza ezidinga ukushisa okufanayo kwezindawo ezinkulu. Zivame ukusetshenziswa ezithandweni zezimboni, izinqubo zokushisa ukushisa kanye nokukhiqizwa kwe-semiconductor.
Izakhi zokushisa ze-molybdenum ezimise okwe-U, ngakolunye uhlangothi, zilungele izinhlelo zokusebenza ezidinga ukushisa okugxilile endaweni ethile. Zivame ukusetshenziswa ezinhlelweni ezifana neziko le-vacuum, izinqubo ze-sintering kanye nokusabela kwamakhemikhali okushisa okuphezulu.
Kokubili izakhi zokushisa ze-molybdenum ezimise okwe-W futhi ezimise okwe-U zingenziwa kusetshenziswa i-molybdenum heat wire, eyaziwa ngokumelana nokushisa okuphezulu nokuqina. Intambo yokushisisa ingahlanganiswa futhi ilolongelwe ekucushweni okufunayo ukuze kwakhiwe izinto zokushisisa ezisebenza kahle nezithembekile zezinhlelo zokusebenza ezihlukene zezimboni nezesayensi.

Izimo zokusetshenziswa kwentambo yokushisisa ye-molybdenum ikakhulukazi ihlanganisa indawo esetshenziswayo, usayizi nokuklama komumo, ukukhethwa kokumelana nokumelana, nendlela yokufaka.
Indawo okusetshenziswa kuyo: Intambo yokushisisa ye-molybdenum ivamise ukusetshenziswa endaweni evalekile noma endaweni evikelwe igesi engasebenzi, njengasezisetshenziswa ezisezingeni eliphezulu lokushisa njengeziko le-vacuum. Ukukhethwa kwale ndawo kusiza ukugcina ukuzinza kwentambo yokushisa ye-molybdenum nokwandisa impilo yayo yesevisi.
Usayizi nokuma komklamo: Usayizi nokuma komugqa wokushisisa we-molybdenum udinga ukunqunywa ngokuya ngosayizi nesakhiwo sangaphakathi sesithando somlilo ukuze kuqinisekiswe ukuthi singashisisa ngokulinganayo izinto ezingaphakathi kwesithando somlilo. Ngesikhathi esifanayo, ukuma komugqa wokushisa we-molybdenum nakho kudinga ukucabangela ukubekwa kwezinto kanye nendlela yokushisa ukushisa ukuze kuthuthukiswe ukusebenza kahle kokushisa.
Ukukhethwa kokumelana nokumelana: Ukumelana nomugqa wokushisisa we-molybdenum kuzothinta umphumela wawo wokushisa nokusetshenziswa kwamandla. Ngokuvamile, i-resistivity ephansi, umphumela wokushisa ungcono, kodwa ukusetshenziswa kwamandla kuzokwanda ngokufanele. Ngakho-ke, enkambweni yokuklama, kuyadingeka ukukhetha ukuphikiswa okufanele ngokusekelwe ezidingweni zangempela.
Indlela yokufaka: Umugqa wokushisisa we-molybdenum kufanele umiswe kubakaki ngaphakathi kwesithando somlilo futhi ugcinwe ebangeni elithile ukuze kukhishwe ukushisa. Ngesikhathi esifanayo, ukunakwa kufanele kukhokhwe ekuvimbeleni ukuthintana okuqondile phakathi komugqa wokushisa we-molybdenum kanye nodonga lwesithando somlilo ukuze kugwenywe izifunda ezimfushane noma ukushisa ngokweqile.
Lezi zimo zokusetshenziswa ziqinisekisa ukusebenza nokuphepha kwezintambo zokushisa ze-molybdenum ezindaweni ezithile, kuyilapho zinikeza iziqinisekiso zokusetshenziswa kwazo ezindaweni ezishisa kakhulu.
Isikhathi esisithathayo ukuze isithando somlilo se-molybdenum sishise sibe ngu-1500 degrees Celsius singahluka kuye ngokuthi isithando somlilo esithile, amandla aso kanye nezinga lokushisa lokuqala lesithando somlilo. Kodwa-ke, ngokuvamile kulinganiselwa ukuthi isithando somlilo esinezinga lokushisa eliphezulu esingafinyelela ku-1500 degrees Celsius singase sithathe cishe imizuzu engama-30 kuya kwengama-60 ukufudumala ukusuka ekamelweni kuya ezingeni lokushisa elidingekayo.
Kuhle ukuqaphela ukuthi izikhathi zokushisisa zingathintwa izinto ezifana nosayizi wesithando somlilo kanye nokufakwa kwensimbi, okokufaka kwamandla, kanye nesici esithile sokushisisa esisetshenzisiwe. Ngaphezu kwalokho, izinga lokushisa lokuqala lesithando somlilo kanye nezimo ezizungezile zemvelo ezungezile nazo zithinta isikhathi sokushisa.
Ukuze uthole izikhathi zokushisa ezinembile, kunconywa ukuthi ubhekisele ekucacisweni komkhiqizi kanye nemihlahlandlela yesithando somlilo se-molybdenum esisetshenziswayo.
Igesi engcono kakhulu yeziko le-molybdenum wire ngokuvamile i-hydrogen ehlanzekile kakhulu. Ngenxa yokuthi i-hydrogen ayisebenzi futhi iyehlisa, ivamise ukusetshenziswa ezithandweni ezinokushisa okuphezulu kwe-molybdenum nezinye izinsimbi eziphikisayo. Uma isetshenziswa njengesimo somlilo, i-hydrogen isiza ekuvimbeni i-oxidation kanye nokungcoliswa kocingo lwe-molybdenum emazingeni okushisa aphezulu.
Ukusetshenziswa kwe-hydrogen ehlanzekile kakhulu kusiza ekudaleni umoya ohlanzekile nolawulwayo ngaphakathi kwesithando somlilo, okubalulekile ekuvimbeleni ama-oxide ukuthi akheke ocingweni lwe-molybdenum ngesikhathi sokushisa. Lokhu kubaluleke kakhulu ngoba i-molybdenum isheshe ikhiphe oksijini emazingeni okushisa aphezulu, futhi ukuba khona komoyampilo noma amanye amagesi asebenzayo kunganciphisa ukusebenza kwayo.
Kubalulekile ukuqinisekisa ukuthi i-hydrogen esetshenzisiwe ihlanzekile kakhulu ukuze kuncishiswe ingozi yokungcola nokugcina izakhiwo ezidingekayo zocingo lwe-molybdenum. Ukwengeza, isithando somlilo kufanele sakhelwe ukuphatha ngokuphepha nokulawula ukugeleza kwe-hydrogen ukuze kuqinisekiswe ukusebenza okuphephile. Uma usebenzisa i-hydrogen nanoma iyiphi enye igesi esithandweni se-molybdenum, hlala ulandela imihlahlandlela yomkhiqizi nezincomo zokuphepha.
