Indlela yokwenza isithando somlilo se-muffle sihlale isikhathi eside

i-muffle furnace iyimishini yokushisa yendawo yonke, ngokuya ngokubukeka nokuma ingahlukaniswa ngebhokisi lesithando somlilo se-muffle, isithando somlilo se-tube. Indlela yokwenza ukuthi ihlale isikhathi eside?

1. Hlola njalo ukuthi izintambo ezishisayo zengxenye ngayinye yesithando somlilo we-muffle zikhululekile, ukuthi othintana nabo be-AC contactor basesimweni esihle, futhi uma kukhona ukwehluleka kwenzeka, kufanele kulungiswe ngesikhathi.

2. Ithuluzi kufanele libekwe endaweni eyomile, engena umoya, igesi engagqwali, izinga lokushisa lendawo yokusebenza liyi-10-50 ℃, izinga lokushisa elihlobene alikho ngaphezu kwama-85%.

3. Ngesithando somlilo wohlobo lwe-silicon carbide rod, uma induku ye-silicon carbide itholakala yonakalisiwe, kufanele kushintshwe induku entsha ye-silicon carbide enencazelo efanayo kanye nenani elifanayo lokumelana. Lapho ushintsha isithando somlilo se-muffle, qala ngokususa isembozo sokuvikela kanye ne-silicon carbide rod chuck kuzo zombili iziphetho zesithando somlilo se-muffle, bese ukhipha i-silicon carbide rod eyonakele. Njengoba induku ye-silicon carbide ibuthakathaka, qaphela lapho ufaka. Ikhanda kufanele liboshwe ukuze lixhumane kahle nenduku ye-silicon carbide. Uma i-chuck i-oxidized kakhulu, kufanele ishintshwe kufakwe entsha. Izikhala phakathi kwezimbobo ezifakwayo kuzo zombili iziphetho zezinti ze-silicon carbide kufanele zivalwe ngezintambo ze-asbestos.

Izinga lokushisa lomlilo we-muffle akufanele lidlule izinga lokushisa lokusebenza lika-1400 ℃. I-silicon carbide rod ivunyelwe ukusebenza ngokuqhubekayo amahora angu-4 ekushiseni okuphezulu kakhulu.

Ngaphezu kwalokho, i-silicon carbide heat element iyisici sokushisa esingeyona insimbi eyenziwe nge-silicon carbide njengento eyinhloko eluhlaza. Inezici ze-coefficient encane yokwandisa, ukungaguquki, ukuqina kwamakhemikhali okuqinile, impilo ende yesevisi, nokufakwa nokugcinwa okulula. Umthwalo ongaphezulu we-silicon carbide rod = amandla akalwe / indawo engaphezulu yengxenye yokushisa (W/cm2)

Umthwalo ongaphezulu wentonga ye-silicon carbide yesithando somlilo esinezinga eliphezulu lokushisa inobudlelwano obuhle nobude bempilo yayo yesevisi. Ngakho-ke, kufanele ilawulwe ngokuqinile ngaphakathi kwebanga lomthwalo elivumelekile lapho inikezwe amandla futhi ishiswa, futhi ugweme ukugcwala ngokweqile.
