Iimeko zokusetyenziswa kocingo lokufudumeza i-molybdenum ikakhulu ziquka indawo yokusetyenziswa, ubungakanani kunye noyilo lokumila, ukhetho lokumelana, kunye nendlela yokufakela.
Indawo esetyenziswayo: Ucingo lokufudumeza iMolybdenum ludla ngokusetyenziswa kwindawo ekhuselekileyo okanye kwindawo ekhuselekileyo yegesi engasebenziyo, njengakwizixhobo zobushushu obuphezulu njengeziko lokufunxa. Ukukhethwa kwesi singqongileyo kunceda ukugcina ukuzinza kwe-molybdenum yokufudumala ucingo kunye nokwandisa ubomi bayo benkonzo.
Ubungakanani kunye noyilo lwemilo: Ubungakanani kunye nokuma komgca wokufudumeza we-molybdenum kufuneka kumiselwe ngokobukhulu kunye nesakhiwo sangaphakathi sesithando somlilo ukuze kuqinisekiswe ukuba sinokutshisa ngokufanayo izinto ezingaphakathi kwesithando somlilo. Ngexesha elifanayo, ukumila komgca wokufudumala kwe-molybdenum kufuneka kuqwalaselwe ukubekwa kwezinto kunye nendlela yokushisa ukushisa ukuphucula ukusebenza kakuhle kokufudumeza.
Ukukhethwa kwe-resistantivity: Ukuxhathisa kwe-molybdenum strip yokufudumala kuya kuchaphazela umphumo wayo wokufudumeza kunye nokusetyenziswa kwamandla. Ngokuqhelekileyo, i-resistivity ephantsi, ingcono isiphumo sokufudumeza, kodwa ukusetyenziswa kwamandla kuya kwanda ngokufanelekileyo. Ngoko ke, kwinkqubo yokuyila, kuyimfuneko ukukhetha ukuxhathisa okufanelekileyo ngokusekelwe kwiimfuno zangempela.
Indlela yokufakela: Umtya wokufudumeza we-molybdenum kufuneka ulungiswe kwi-bracket ngaphakathi kwesithando somlilo kwaye ugcinwe kumgama othile wokutshatyalaliswa kobushushu. Ngelo xesha, ingqalelo kufuneka ihlawulwe ekuthinteleni ukudibanisa ngokuthe ngqo phakathi komtya wokufudumeza we-molybdenum kunye nodonga lwesithando somlilo ukuphepha iisekethe ezimfutshane okanye ukufudumala.
Ezi meko zokusetyenziswa ziqinisekisa ukusebenza kunye nokukhuseleka kweengcingo zokufudumala ze-molybdenum kwiindawo ezithile, ngelixa zibonelela ngeziqinisekiso zesicelo sabo kwiindawo eziphezulu zokushisa.
Ixesha elithathayo ukuba i-molybdenum wire furnace ifudumale ukuya kwi-1500 degrees Celsius inokwahluka ngokuxhomekeke kwisithando somlilo esithile, amandla ayo kunye nobushushu bokuqala beziko. Nangona kunjalo, kuqikelelwa ngokubanzi ukuba iziko lobushushu obuphezulu elikwaziyo ukufikelela kwi-1500 degrees Celsius lingathatha malunga nemizuzu engama-30 ukuya kuma-60 ukufudumala ukusuka kubushushu begumbi ukuya kubushushu obufunekayo bokusebenza.
Kuyafaneleka ukuba uqaphele ukuba amaxesha okufudumeza anokuchatshazelwa zizinto ezifana nobukhulu besithando somlilo kunye nokugquma, igalelo lamandla, kunye nesixhobo sokufudumeza esisetyenzisiweyo. Ukongezelela, ukushisa kokuqala kwesithando somlilo kunye neemeko ezizungezile zendawo engqongileyo nazo zichaphazela ixesha lokufudumala.
Ukuze ufumane amaxesha okufudumala achanekileyo, kuyacetyiswa ukuba ubhekisele kwiinkcukacha zomenzi kunye nezikhokelo ze-furnace ye-molybdenum esetyenziswayo.
Eyona gesi ilungileyo kwiziko locingo lwemolybdenum idla ngokuba yi-hydrogen ecocekileyo. Ngenxa yokuba i-hydrogen ayisebenzi kwaye iyancipha, isoloko isetyenziswa kwiziko lobushushu obuphezulu kwi-molybdenum kunye nezinye iintsimbi ezichasayo. Xa isetyenziswa njengeatmosfera yesithando somlilo, ihydrogen inceda ekuthinteleni i-oxidation kunye nokungcoliseka kocingo lwemolybdenum kumaqondo obushushu aphezulu.
Ukusetyenziswa kwe-hydrogen ephezulu ecocekileyo kunceda ukudala umoya ococekileyo kunye nokulawulwa ngaphakathi kwesithando somlilo, okubaluleke kakhulu ukukhusela i-oxides ekubunjweni kwi-wire molybdenum ngexesha lokufudumala. Oku kubaluleke ngakumbi kuba i-molybdenum ikhawuleza i-oxidize kumaqondo okushisa aphezulu, kwaye ubukho be-oksijini okanye ezinye iigesi ezisebenzayo zinganciphisa ukusebenza kwayo.
Kubalulekile ukuqinisekisa ukuba i-hydrogen esetyenzisiweyo icocekile kakhulu ukunciphisa umngcipheko wokungcola kunye nokugcina iimpawu ezifunekayo zocingo lwe-molybdenum. Ukongeza, isithando somlilo kufuneka siyilwe ukuphatha ngokukhuselekileyo nokulawula ukuhamba kwe-hydrogen ukuqinisekisa ukusebenza ngokukhuselekileyo. Xa usebenzisa i-hydrogen okanye nayiphi na enye igesi kwisithando somlilo se-molybdenum, soloko ulandela izikhokelo zomenzi kunye neengcebiso zokhuseleko.
