Ukuveliswa kwezinto ezintsha zenzululwazi nobuchwepheshe luncedo olukhulu ekuphuculeni imveliso. I-vacuum sintering furnace ngumzekelo omhle. Isetyenziswa ngokubanzi kwimveliso yamashishini yanamhlanje. Ukusetyenziswa kwe-vacuum sintering furnace iphucule kakhulu iipropathi zoomatshini kunye neekhemikhali zezixhobo, kodwa ezi zinto zilandelayo kusafuneka ziqwalaselwe ngexesha lokusetyenziswa:
1. Ukucoca: Ngaphambi kokusebenzisa i-vacuum sintering furnace, kuyimfuneko ukucoca umzimba wesithando somlilo kunye negumbi lesithando somlilo ukuqinisekisa umgangatho wesampulu ye-sintered kunye nefuthe le-sintering. Ngexesha elifanayo, kuyimfuneko ukucoca rhoqo kunye nokugcina umzimba wesithando somlilo kunye nesithando somlilo ukuze ugweme ukungcoliswa kweesampuli.
2. Ukulawulwa kwenkqubo yokufudumala: Ukunyuka kwangaphakathi kweqondo lokushisa kwi-vacuum sintering furnace kufuneka kulawulwe ngokufudumeza. Ngethuba lokusebenza, ukushisa okushushu kunye nexesha kufuneka kulawulwe ngokungqongqo, ngokukodwa izinga lokushisa ngexesha lenkqubo ye-sintering akufanele likhawuleze, ngaphandle koko kunokubangela ukuqhekeka okanye umonakalo ngaphakathi kwesampuli.
3. Ukukhethwa kwegesi yokulondoloza: Ukukhethwa kwegesi yokulondoloza kuchaphazela ngokuthe ngqo umgangatho kunye nokuzinza kweesampuli ze-sintered. Ngethuba lenkqubo yesicelo, kuyimfuneko ukukhetha igesi efanelekileyo yokukhusela ukuphucula ubuninzi kunye namandla esampuli, ukugcina ukuzinza kwesampuli kunye nokukhusela i-oxidation.
4. Ukulawulwa kwendalo ye-Sintering: Kwi-vacuum sintering furnace, iiparamitha zokusingqongileyo ezifana neqondo lokushisa kunye noxinzelelo kufuneka zilawulwe ngokungqongqo ukuze kuqinisekiswe ukuba isampuli inokugcina imeko ezinzileyo ngexesha lenkqubo ye-sintering. Kwangaxeshanye, iqondo levacuum kwindawo ye-sintering nayo ifuna ukulawulwa ukunqanda i-oxides okanye ezinye izinto ezingcolisa umphezulu wesampulu.
5. Ukukhethwa kwesikhongozeli sokusebenza: Ngexesha lenkqubo ye-sintering, kuyimfuneko ukukhetha isitya esisebenzayo esifanelekileyo ukuhlangabezana neemfuno zesampulu ye-sintering. Ubungakanani besikhongozeli kufuneka buthathele ingqalelo ubungakanani kunye nobungakanani besampulu, kwaye izinto zesikhongozeli kufuneka zimelane nobushushu obuphezulu kunye nokubola ukuze kuqinisekiswe ukuba umgangatho wesampulu awuchaphazeleki ngexesha lokusebenza.
Kusenjalo isivakalisi esifanayo, ukusebenza kwesithando se-vacuum sintering kufuna ukuthotyelwa okungqongqo kunye neenkqubo zokusebenza kunye nokuqwalaselwa kokhuseleko, kunye nokukhethwa okufanelekileyo kweeparamitha ezifana nokusingqongileyo kunye negesi yokulondoloza ukuqinisekisa ukuba umphumo we-sintering kunye nomgangatho wesampuli.
