Izinyathelo zokuphepha zokusebenza kwe cleaner emkhathini somlilo

I-vacuum atmosphere furnace iwuhlobo lwesithando somlilo esingacocwa futhi sidlule emkhathini. Inezinhlobo eziningi ezahlukene zezithando ezifana nohlobo lwebhokisi, isithando somlilo seshubhu, nesithando somlilo esiphakamisayo. Nakuba kunezinhlobo eziningi, izinyathelo zokuqapha ngesikhathi sokusebenza azimbi. Ngezansi Ake sithole:

1. Iziqhumiso ze-vacuum umoya wokushisa ophezulu azikwazi ukulayishwa ngokweqile. Izinga lokushisa eliphakeme lokusebenza lisho izinga lokushisa elivumelekile le-elementi endaweni engenalutho, hhayi izinga lokushisa lempahla yokushisisa noma izinga lokushisa elizungeze into yokushisisa. Kumele kuqashelwe ukuthi izinga lokushisa le-vacuum heat element ngokwayo liyi-100 ° C ngaphezu kwezinga lokushisa lendawo ezungezile noma izinga lokushisa elishisayo.

2. Lapho ukala ukufana kwezinga lokushisa kwesithando somlilo se-vacuum, naka indlela yokumisa yokuxhumana kokulinganisa izinga lokushisa kanye nebanga elisuka endaweni yokushisa. Sebenzisa amabhulashi, imishanelo noma umoya ocindezelwe, izicoci ze-vacuum, njll. ukuhlanza isithando somlilo esithandweni somoya kaningi (okungenani nsuku zonke noma ngaphambi kweshifu ngalinye) ukuze uvimbele ukungcola okufana nesikali se-oxide esithandweni ekuweleni ezintweni ezishisayo, isikhashana- ukujikeleza, ngisho nokushisa izinti zokushisisa ze-molybdenum . Ipuleti elingaphansi, induku yokushisisa i-molybdenum, ungqimba lokufakwa kwesithando somlilo nezinye izakhi zensimbi ezikwazi ukumelana nokushisa kufanele zihlanzwe njalo lapho zisetshenziswa. Ukushaya kunqatshelwe ngokuphelele, futhi isikali sabo se-oxide singasuswa ngokucophelela.

3. Ngemuva kokuthi isithando somlilo sishise, isistimu ye-vacuum ayikwazi ukubhujiswa ngokuzumayo, ingasaphathwa eyokuvula umnyango wesithando somlilo. Qaphela ukuthi inkinobho ye-vacuum gauge kufanele ivalwe ngaphambi kokugcwalisa umkhathi ukuze kuvinjwe igeji ye-vacuum ekugugeni. Uma izinga lokushisa lingaphezu kuka-400 ℃, akufanele lipholiswe ngokushesha. Gwema ukusabela phakathi kwezinto zokushisisa nemikhiqizo, ikakhulukazi uma ithusi, i-aluminium, i-zinc, ithini, umthofu, njll. ihlangana nezinto zokushisisa i-vacuum, kungaba impushana, uketshezi oluncibilikisiwe noma umusi, njll., ukuvimbela ukuguguleka nokwakheka “imigodi” ebusweni besici sokushisa kagesi. , I-cross-section iba yincane, futhi iyasha ngemva kokushisa ngokweqile. Lapho izingxenye zokudlulisela zitholakala zibambekile, zingalungile emkhawulweni, nokwehluleka kokulawula, kufanele ziqedwe ngokushesha, futhi ungaphoqi ukusebenza ukuze ugweme ukulimala ezingxenyeni.

4. Izingxenye zensimbi ezikwazi ukumelana nokushisa njengepuleti elingaphansi lesithando somlilo se-vacuum, izinduku zokufudumeza i-molybdenum, ungqimba lokufakwa kwesithando somlilo, njll. kufanele zihlanzwe njalo lapho zisetshenziswa. Ukungqongqoza akuvunyelwe ngokuqinile, futhi isikali se-oxide singasuswa ngokucophelela. Uma isikali se-iron oxide nokunye ukungcola kungasuswa ngesikhathi, indawo encibilikisiwe izovutha ngongqimba lwe-insulation, okubangela ukuba ucingo lwe-molybdenum luncibilike.

5. Ngemva kokuba isithando somlilo sishise, uhlelo lwe-vacuum alukwazi ukubhujiswa ngokuzumayo, ingasaphathwa eyokuvula umnyango wesithando somlilo. Qaphela ukuthi inkinobho ye-vacuum gauge kufanele ivalwe ngaphambi kokugcwalisa umkhathi ukuze kuvinjwe igeji ye-vacuum ekugugeni. Uma izinga lokushisa lingaphezu kuka-400 ℃, akufanele lipholiswe ngokushesha. Ngesici sokushisa kwe-vacuum, kulula ukubangela i-oxidation lapho izinga lokushisa liphezulu, i-vacuum degree ayilungile, futhi izinguquko ezibandayo nokushisa zinkulu. Esithandweni sokushisisa i-molybdenum, ngesikhathi sokusetshenziswa nokugcinwa okuvamile, kufanele sipholiswe sibe ngaphansi kuka-200°C ngaphambi kokuba i-nitrogen evikelayo imiswe. Umnyango wesithando somlilo ungavulwa kuphela ngaphansi kuka-80°C.

6. Uhlelo lokupholisa luyingxenye ebalulekile yesithando somlilo se-vacuum. Umjikelezo wamanzi okupholisa kufanele ugcinwe ungavinjelwe, ngaphandle kwalokho izinga lokushisa lamanzi lizokhuphuka futhi libangele umshini ukuyeka. Lena inkinga evame ukunganakwa lapho isithando somlilo esisebenza emkhathini sisebenza. Kungase kubangele umonakalo omkhulu esithandweni somlilo se-vacuum esiphezulu lapho kungagadiwe. Inhloso yokwelapha amanzi okupholisa ngosizo lokubola kwezinto eziphilayo kanye nezindlela zamakhemikhali ukugcina amaminerali emisiwe futhi kuncishiswe ukunqwabelana kwenhlabathi epayipini lenjoloba, ishubhu lenyoka kanye nebhantshi lamanzi, ukuze amanzi ahambe kahle. Lokhu ngokuvamile kwenziwa umshini ozenzakalelayo, ongaqapha ukuhamba kwamanzi, ugcwalise ngokuzenzakalelayo ama-agent amakhemikhali, ukhiphe umzila wamanzi, futhi wengeze amanzi ahlanzekile.
