Indlela yokugcina isithando somlilo?

I-Muffle furnace idla ngokubizwa ngokuba zezi ntlobo zilandelayo: isithando sombane, isithando somlilo, i-Maofu furnace, kunye ne-muffle furnace. I-muffle furnace sisixhobo sokufudumala ngokubanzi, esinokwahlulwa sibe yibhokisi yomlilo, i-tube furnace kunye ne-crucible furnace ngokwembonakalo kunye nokuma. Oku kulandelayo kuchaza indlela yokugcinwa kwesithando somlilo:

1. Xa i-furnace ye-muffle isetyenziswe kanye okanye isetyenziswe kwakhona emva kwexesha elide lokungasebenzi, kufuneka ibhakwe. Ixesha le-oven kufuneka libe yi-200 ° C ukuya kwi-600 ° C iiyure ezine. Xa kusetyenziswa, ukushisa kwesithando somlilo akufanele kudlule iqondo lokushisa elilinganisiweyo, ukuze ungatshisi into yokufudumala. Akuvumelekanga ukugalela ulwelo olwahlukeneyo kunye nezinyithi ezinyibilikayo ngokulula kwiziko. I-muffle furnace isebenza kwiqondo lobushushu elingaphantsi kwe-50 ℃ ngaphantsi kobushushu obuphezulu, kwaye ucingo lwesithando somlilo lunobomi obude.

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. I-thermocouples yokulinganisa ubushushu edibeneyo kumlawuli inokuphazamisa umlawuli, ebangela ukuba umlawuli abonise ixabiso lokutsiba abalinganiswa, kwaye impazamo yokulinganisa yanda. Ukuphakama kweqondo lokushisa lesithando somlilo, le nto ibonakala ngokucacileyo. Ngoko ke, ityhubhu yokukhusela isinyithi (igobolondo) ye-thermocouple kufuneka igxilwe kakuhle, kwaye ukuba kuyimfuneko, sebenzisa i-thermocouple enemveliso yocingo oluthathu. Ngokufutshane, i-***manyathelo kufuneka athathwe ukunciphisa ukuphazamiseka.

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

6. Gcina igumbi lesithando somlilo licocekile kwaye ususe i-oxides kwisithando somlilo ngexesha.

7. Ngethuba lokusetyenziswa, xa usebenzisa izinto ze-alkali ukudibanisa iisampuli okanye ukutshisa idiphozithi kwisithando somlilo, iimeko zokusebenza kufuneka zilawulwe ngokungqongqo, kwaye i-plate refractory kufuneka ibekwe phantsi kwesithando somlilo ukukhusela ukubola kwesithando somlilo.
