Izinkombandlela zokuphatha kanye nokusetshenziswa kwe-Crucible

Ama-crucibles iziqukathi ezibalulekile ezisetshenziselwa-ukuncibilika okuphezulu kwezinga lokushisa, ukufudumeza, noma ukusabela kumalabhorethri nokukhiqizwa kwezimboni. Ukuphatha kwabo okufanele kuthinta ngokuqondile ukuphepha kokuhlolwa kanye nokunemba kwemiphumela. Okulandelayo yizinqubo ezijwayelekile zokuphatha i-crucible kanye nezinyathelo zokuphepha.

1. Ukulungiselela

Ngaphambi kokusetshenziswa, hlola ubuqotho be-crucible ukuze uqinisekise ukuthi ayinayo imifantu noma amaphutha. Nquma ukubekezelela izinga lokushisa kwento (okufana ne-quartz, i-ceramic, noma i-graphite) ukugwema ukushisa ngokweqile. Kunconywa ukushisa i-crucible entsha ngaphambi kokusetshenziswa kokuqala ukuze kuqedwe ukucindezeleka kwangaphakathi. Futhi, khetha ama-crucible tongs afanayo ukuze uqinisekise ukubamba okuphephile kanye{3}}nokumelana nezinga lokushisa eliphezulu.

2. Ukulayisha nokubeka

Uma ungeza okubalulekile ku-crucible, khawula inani lingabi ngaphezu{0}}kuzingxenye ezintathu kwezintathu zomthamo walo ukuze uvimbele ukuchichima ngesikhathi sokushisisa. Uma izinto zokuphatha zijwayele ukuchaphazeka (njengezimpushana zensimbi), zimboze ngelendlalelo esiyisivikelo noma wehlise izinga lokwengeza. Beka i-crucible kuphedi ekwazi ukumelana nokushisa-noma isitendi esizinikele ukuze uqinisekise ngisho nokushisisa phansi ukuze uvimbele ukushisisa ngokweqile kwendawo kanye nokuqhekeka.

3. Ukulawula Ukushisa Nokusebenza

Ukushisa kufanele kwenziwe kancane kancane ukuze kugwenywe ukushisa okungazelelwe okungase kubangele ukushaqeka kokushisa. Uma usebenzisa isithando somlilo se-muffle noma isithando somlilo sikagesi, kunconywa ukwandisa izinga lokushisa ekushiseni okuqondisiwe ngesilinganiso se-5-10℃/ min, futhi uqaphe isimo ngembobo yokubuka. Uma ukushukuma noma ukusampula kuyadingeka, okokuvikela kufanele kugqokwe futhi kusetshenziswe amathuluzi azinikele. Ukuxhumana okuqondile nomzimba obethelekayo akuvunyelwe ngokuphelele.

4. Ukupholisa nokuthunyelwe{1}}Kuyacutshungulwa

Ngemuva kokushisa, i-crucible kufanele ivunyelwe ukupholisa ngokwemvelo ekamelweni lokushisa. Ukupholisa ngokushesha (njengokugeza ngamanzi) akuvunyelwe. Ukuhambisa i-crucible ngenkathi kushisa kungase kubangele ukuthi iqhume. Linda kuze kuphole kuze kufike ezingeni lokushisa eliphephile ngaphambi kokuyihambisa. Hlanza noma iyiphi insalela ngokushesha ngemva kokusetshenziswa ukuze uvimbele izinto ezibolayo ukuthi zinganamatheli odongeni lwangaphakathi futhi zilimaze.

5. Izinyathelo Zokuphepha

Gqoka{0}}amagilavu ​​okushisa aphezulu, izibuko, nezingubo zokuzivikela ngesikhathi sonke sokusebenza, futhi ugweme izinto ezivutha umlilo. Uma i-crucible iphuka, yeka ukusebenzisa ngokushesha futhi ulahle kahle izingcezu ukuvimbela imihuzuko nokungcoliswa kwemvelo.

Ukuphatha kahle i-crucible kubalulekile ekuphepheni kokuhlolwa nokuthembeka kwedatha. Ukubambelela ngokuqinile ezinkambisweni kunganciphisa kakhulu ubungozi futhi kunwebe ukuphila kwezinto zokusebenza.
