Indlela yokulondoloza isithando somlilo se-muffle?

Isithando somlilo se-muffle sivame ukubizwa ngalezi zinhlobo ezilandelayo: isithando somlilo sikagesi, isithando somlilo esingaguquki, i-Maofu furnace, nesithando somlilo se-muffle. Isithando somlilo se-muffle siwumshini wokushisa ojwayelekile, ongahlukaniswa phakathi kwesithando somlilo sebhokisi, isithando somlilo se-tube kanye nesithando somlilo esiqhekezayo ngokusho kokubukeka nokuma. Okulandelayo kuchaza indlela yokunakekela isithando somlilo se-muffle:

1. Uma isithando somlilo se-muffle sisetshenziswa kanye noma sisetshenziswa futhi ngemva kwesikhathi eside sokungasebenzi, kufanele sibhakwe. Isikhathi sehhavini kufanele sibe ngu-200 ° C kuya ku-600 ° C amahora amane. Lapho isetshenziswa, izinga lokushisa lomlilo akufanele lidlule izinga lokushisa elilinganiselwe, ukuze lingashisi isici sokushisa. Akuvunyelwe ukuthulula uketshezi oluhlukahlukene nezinsimbi ezincibilika kalula esithandweni. Isithando somlilo se-muffle sisebenza ezingeni lokushisa elingaphansi kuka-50 ℃ ngaphansi kwezinga lokushisa eliphezulu, futhi intambo yesithando somlilo iphila isikhathi eside.

2. Isithando somlilo se-muffle kanye nesilawuli kufanele sisebenze endaweni lapho umswakama ohlobene ungadluli ama-85%, futhi lungekho uthuli oluqhumayo, igesi eqhumayo noma igesi ebolayo. Lapho impahla yensimbi enamafutha noma okufanayo idinga ukushiswa, inani elikhulu legesi eliguquguqukayo lizothinta futhi ligxumeke indawo yokushisa kagesi, okubangela ukuba libhujiswe futhi lifinyeze ubude bokuphila. Ngakho-ke, ukushisa kufanele kuvinjwe ngesikhathi futhi isitsha kufanele sivalwe noma sivulwe kahle ukuze sisisuse.

3, isilawuli sesithando somlilo se-muffle kufanele sikhawulelwe ukusebenzisa ebangeni lokushisa elizungezile lika-0-40 ℃.

4. Ngokwezidingo zobuchwepheshe, hlola njalo ukuthi i-wiring yesithando somlilo kagesi kanye nesilawuli sisesimweni esihle. Ama-thermocouples okulinganisa izinga lokushisa axhunywe kusilawuli angase aphazamise isilawuli, kubangele inani elibonisa isilawuli leqe izinhlamvu, futhi iphutha lokulinganisa liyanda. Ukuphakama kwezinga lokushisa kwesithando somlilo, lesi simo sisobala kakhulu. Ngakho-ke, ithubhu yokuvikela insimbi (igobolondo) ye-thermocouple kufanele ibe nesisekelo esihle, futhi uma kunesidingo, sebenzisa i-thermocouple enokukhishwa kwezintambo ezintathu. Kafushane, *** izinyathelo kufanele zithathwe ukunciphisa ukuphazamiseka.

5. Musa ukukhipha i-thermocouple ngokuzumayo ekushiseni okuphezulu ukuvimbela ijazi ekuqhumeni.

6. Gcina ikamelo lomlilo lihlanzekile futhi ukhiphe ama-oxide esithandweni ngesikhathi.

7. Ngesikhathi sokusetshenziswa, uma usebenzisa izinto ezine-alkali ukuhlanganisa amasampula noma ukushisa amadiphozithi esithandweni, izimo zokusebenza kufanele zilawulwe ngokuqinile, futhi ipuleti le-refractory kufanele libekwe phansi kwesithando somlilo ukuvimbela ukugqwala kwesithando somlilo.
