Uyisebenzisa kanjani iziko lomlilo ngokuchanekileyo

1. When the muffle furnace is used for the first time or used again after a long period of inactivity, it must be oven-dried. The oven time should be four hours at room temperature 200°C. 200°C to 600°C for four hours. When in use, the maximum furnace temperature must not exceed the rated temperature, so as not to burn the heating element. It is forbidden to pour various liquids and easily soluble metals into the furnace. The muffle furnace is best to work below the maximum temperature of 50 ℃, when the furnace wire has a longer life.

2. Isithando somlilo se-muffle kunye nesilawuli kufuneka sisebenze kwindawo apho umswakama ohambelanayo ungadluli i-85%, kwaye akukho thuli oluqhubekileyo, igesi eqhumayo okanye igesi eyingozi. Xa izinto zetsimbi kunye negrisi okanye izinto ezinje zifuna ukufudumeza, ubuninzi begesi eguquguqukayo iya kuchaphazela kwaye igxumeke umphezulu wento yokufudumala yombane, ibangele ukuba ibhujiswe kwaye inciphise ixesha lokuphila. Ngoko ke, ukufudumeza kufuneka kuthintelwe kwangethuba kwaye isikhongozeli kufuneka sivalwe okanye sivulwe ngokufanelekileyo ukusisusa.

3, isilawuli somlilo we-muffle kufuneka sithintelwe ukusetyenziswa kuluhlu lobushushu obuphakathi kwe-0-40 ℃.

4. Ngokweemfuno zobugcisa, khangela rhoqo ukuba i-wiring yesithando sombane kunye nomlawuli ukwimeko efanelekileyo, nokuba isalathisi sesalathisi sinamathele okanye sigxininisekile xa sihamba, kwaye sebenzisa i-potentiometer ukulinganisa imitha ngenxa yensimbi yamagnetic. , i-demagnetization, ukwanda kweengcingo, kunye ne-shrapnel.

5. Musa ukukhupha i-thermocouple ngokukhawuleza kwiqondo lokushisa eliphezulu ukukhusela ibhatyi ekuqhumeni.

6. Njalo gcina i-muffle furnace icocekile kwaye ususe ii-oxides eziko ngexesha.
