Okokuqala, ngemva kokunciphisa umthamo kawoyela esithandweni sokucima uwoyela we-vacuum uye ethangini likawoyela elisebhasikidini elijwayelekile, ibanga phakathi kobuso bukawoyela kanye nobuso bawo obuqondile kufanele okungenani libe yi-100 mm,
Uma ibanga lingaphansi kuka-100 mm, izinga lokushisa lobuso bamafutha lizoba phezulu kakhulu, okungaholela ekuqhumeni kwesithando somoya.
Okwesibili, i-nitrogen kumele ifakwe ngaphambi kokuba uwoyela ukhishwe esithandweni sokucima uwoyela we-vacuum, kodwa umoya awukwazi ukufakwa. Ukuze kongiwe izindleko, abakhiqizi abaningi abasebenzisi i-nitrogen.
Ngaphezu kwalokho, kungcono ukufaka i-nitrogen ngaphambi kokuba umsebenzi ukhishwe, ngaphandle kwalokho kulula ukubangela ukuqhuma kwemishini yesithando somoya.
Okwesithathu, izinga lokushisa lomsebenzi lidlula umkhawulo lapho kuphuma uwoyela. Ngalesi sikhathi, uwoyela wokucima i-vacuum uzohwamuka, futhi uma usungena emoyeni noma emoyeni, uzoqhuma.
Okwesine, ngaphezu kwemishini yokwelapha ukushisa ngokwayo, ikhwalithi kawoyela wokucima i-vacuum uqobo izobangela nezingozi zokuqhuma, njengowoyela wokucima one-flash point ephansi kanye ne-ignition point ephansi.
Okwesihlanu, ubukhulu kanye nesimo sento yokusebenza ecinyiwe esithandweni sokucima uwoyela we-vacuum nakho kungenye yezizathu zokuqhuma.
Ngakho-ke, wonke umuntu kufanele aqaphele ukuvimbela izingozi ezibangelwa yilezi zizathu. Okokuqala, imishini idinga ukuhlolwa nokugcinwa njalo.
Ukuze kutholakale futhi kufakwe uwoyela ku-vacuum furnace ngesikhathi, kungcono ukuba nomhlinzeki oqinile wamafutha okucima i-vacuum,
Ngoba uwoyela ovela kubakhiqizi abaningi uvame ukuba nezingozi. Okwesibili, uma usayizi wokucima umkhulu, ujiyile futhi ungajwayelekile, kulula ukukhiqiza inani elikhulu lemikhiqizo kawoyela wokucima.
Kudingeka ukunakwa okukhethekile; Okokugcina, hlanza indawo ezungeze ishabhu ukuze ugweme izinto ezivuthayo neziqhumane kanye namagesi asatshalaliswe eduze kwesithando somlilo.
