Yiziphi izinyathelo zokuphepha zokusebenzisa isithando somlilo se-muffle
What are the precautions for using the Isithando somlilo
Isithando somlilo se-muffle singasetshenziselwa ukuhlaziywa kwamakhemikhali, ukuzimisela ngokomzimba kanye nokushisa kwezingxenye ezincane zensimbi ekwelapheni ukushisa kwezingxenye ezincane zensimbi kuma-laboratories ezinkampani zezimboni nezimayini, ucwaningo lwesayensi namanye amayunithi. Kunamaphuzu ambalwa okufanele uwanake ngokukhethekile lapho usebenzisa:
Lapho isithando somlilo se-muffle sisetshenziswa noma sisetshenziswa futhi ngemuva kwesikhathi eside sokungasebenzi, kuyadingeka ukwenza ihhavini. Ihhavini kufanele libe ekamelweni lokushisa 200 ° C amahora amane. Amahora amane ukusuka ku-200°C kuya ku-600°C. Uma isetshenziswa, izinga lokushisa lomlilo akumele lidlule izinga lokushisa elengeziwe ukugwema ukushisa izinto zokushisa zikagesi. Yeka ukuthela uketshezi oluhlukahlukene nezinsimbi ezincibilika kalula esithandweni. Isithando somlilo sisebenza ezingeni lokushisa elingaphansi kuka-50 ℃, futhi intambo yesithando somlilo iphila isikhathi eside.
Kuyadingeka ukuthi isithando somlilo se-muffle kanye nesilawuli sisebenze endaweni lapho umswakama ohambisanayo ungadluli ama-85%, futhi alukho uthuli oluqhumayo, igesi eqhumayo noma igesi edlayo. Lapho izinto zensimbi ezinama-grease noma okufanayo zidinga ukushiswa, amagesi amaningi aguquguqukayo azothinta futhi adle ukubukeka kwesici sokushisa kagesi, ukuyibhubhisa futhi kufinyeze ukuphila kwayo. Ngakho-ke, ukushisa kufanele kuvinjwe ngesikhathi futhi isitsha kufanele sivalwe noma sivulwe kahle futhi sihlanzwe.
Isilawuli sesithando somlilo se-muffle kufanele sikhawulelwe ebangeni lokushisa le-ambient elingu-0-40 ℃. Ungakhiphi i-thermocouple ngokuzumayo ekushiseni okuphezulu ukuvimbela ijazi ukuthi lingaqhekeki.
Ngokwezicelo zamakhono, hlola njalo ukuthi izintambo zesilawuli somlilo we-muffle enezinga eliphezulu lokushisa zinhle kakhulu, ukuthi isikhombi senkomba sibambekile futhi sihlala lapho sinyakaza, bese usebenzisa i-potentiometer ukulungisa ukubukeka kozibuthe, ukukhishwa kazibuthe, ukunwetshwa kwentambo, kanye ne-shrapnel Ukwanda kwamaphutha abangelwa ukukhathala, ukulimala kwebhalansi, njll. Ngokuvamile ukuphikelela ekuhlanzeni iziko lomlilo we-muffle ukuze kukhishwe ama-oxide nezinye izinto esithandweni ngesikhathi.
