Indlela yokusebenzisa nokugcina ithubhu le-quartz esithandweni se-muffle

1. Iphuzu lokuthambisa le-quartz tube liyi-1270 degrees, futhi akufanele lidlule amahora angu-3 uma lisetshenziswe ku-1200 degrees.

2. Gcina ishubhu lomlilo lihlanzekile futhi lihlanzekile. Akufanele kube khona izinto eziyinsalela ezisabela nge-SiO2 kushubhu yesithando somlilo. Lapho ushisa izinto zokwakha, ukuze wenze i-tube yesithando somlilo impilo ende yesevisi, ungafaki izinto ngqo ku-tube yesithando somlilo futhi usebenzise i-crucible efana nesikebhe ukuyibamba.

3. Ngaphansi kwezimo ezijwayelekile, akunconywa ukuthi amakhasimende adlulise i-hydrogen esithandweni somlilo. Ngaphandle kokuqukethwe okungeyona i-hydrogen emkhawulweni wokuqhuma kweziqhumane, uma ikhasimende lidinga ukusebenzisa isithando somlilo ukuze lidlulise i-hydrogen ne-concentration ngaphandle kokugxila kokuqhuma, izinyathelo zokuphepha kufanele zithathwe. Ungami emikhawulweni yomibili yeshubhu yesithando somlilo. Uma udlula i-hydrogen, sicela usebenzise amashubhu ensimbi engagqwali. Ngenxa yokuthi insimbi engagqwali ine-thermal conductivity enkulu kune-quartz, iziphetho zombili zensimbi engagqwali zidinga ukupholiswa ngamanzi, ngaphandle kwalokho izinga lokushisa le-O-ring liphezulu kakhulu futhi alikwazi ukuvaleka.

4. Sicela uqiniseke ukuthi ufaka amapulaki e-ceramic ku-tube yesithando somlilo lapho ushisa, ngaphandle kwalokho izinga lokushisa kuzo zombili iziphetho zeshubhu yesithando lizoba phezulu, futhi ama-O-rings e-flange ngeke akwazi ukumelana nokushisa okuphezulu, okuholela ekutheni umoya omncane oqinile. Ukuphela kuhambisana nokwakhiwa kwenkambu yokushisa elinganiselwe.

5. Lapho ufudumeza, sicela uqiniseke ukuthi ufaka amapulaki esithandweni somlilo we-alumina eshubhuni yesithando somlilo, ubeke ama-2 ohlangothini olulodwa, angu-4 esewonke, ibanga elingaphakathi impela lezinhlangothi ezimbili zepulaki yesithando somlilo lingaba ngu-450mm (ngoba ubude bokushisa. ingxenye ye-HTL1200 i-split tube furnace ingu-400mm) Uma ipulaki yesithando somlilo ingafakwanga, izinga lokushisa kuzo zombili iziphetho zeshubhu yesithando somlilo liphezulu, futhi i-O-ring e-flange ayikwazi ukumelana nokushisa okuphezulu, okwenza ukuqina komoya kube kubi. . Ukubeka ipulaki yesithando somlilo kuzo zombili iziphetho zeshubhu yesithando somlilo kuzosiza ukwakha izinga lokushisa elilinganiselwe. inkambu.

6. Ukumelana nezinga lokushisa kweshubhu le-quartz kuhlobene nobumsulwa bayo. Ukuphakama kokuhlanzeka, kuyanda ukumelana nezinga lokushisa.
