Zeziphi iindlela zokuthintela ukusebenzisa i iziko lomlilo

Isithando somlilo se-muffle singasetyenziselwa ukuhlalutya kweekhemikhali, ukuzimisela ngokomzimba kunye nokufudumeza kweendawo ezincinci zentsimbi kunyango olushushu lweendawo ezincinci zetsimbi kwiilebhu zamashishini zoshishino kunye nemigodi, uphando lwezenzululwazi kunye nezinye iiyunithi. Kukho amanqaku ambalwa okunika ingqalelo ekhethekileyo xa usebenzisa:

Xa i-furnace ye-muffle isetyenziswe okanye isetyenziswe kwakhona emva kwexesha elide lokungasebenzi, kuyimfuneko ukuphumeza i-oven. I-oven kufuneka ibe kwindawo yokushisa kwe-200 ° C iiyure ezine. Iiyure ezine ukusuka kuma-200°C ukuya kuma-600°C. Xa isetyenziswa, ubushushu bomlilo akufunekanga budlule ubushushu obungaphezulu ukuphepha ukutshisa izinto zokufudumeza zombane. Yeka ukugalela ulwelo olwahlukeneyo kunye neentsimbi ezinyibilikayo ngokulula kwiziko. Isithando somlilo siqhutywa kubushushu obungaphantsi kwe-50 ℃, kwaye ucingo lwesithando somlilo lunobomi obude.

Kuyimfuneko ukuba isithando somlilo se-muffle kunye nesilawuli sisebenze kwindawo apho umswakama ohambelanayo awudluli i-85%, kwaye akukho thuli oluqhubekileyo, igesi eqhumayo okanye igesi ephazamisayo. Xa izinto zetsimbi ezinegrisi okanye izinto ezinje zifuna ukufudunyezwa, iigesi ezininzi eziguquguqukayo ziyakuchaphazela kwaye zonakalise ukubonakala kwento yokufudumeza kombane, ukuyitshabalalisa kunye nokunciphisa ubomi bayo. Ngoko ke, ukufudumeza kufuneka kuthintelwe kwangethuba kwaye isitya kufuneka sivalwe okanye sivulwe ngokufanelekileyo kwaye sicocwe.

Isilawuli somlilo we-muffle kufuneka sithintelwe kuluhlu lweqondo lobushushu eliphakathi kwe-0-40 ℃. Musa ukukhupha i-thermocouple ngokukhawuleza kwiqondo lokushisa eliphezulu ukukhusela ibhatyi ekuqhekekeni.

Ngokwezicelo zezakhono, jonga rhoqo ukuba i-wiring yesilawuli somlilo we-muffle enobushushu obuphezulu bugqwesile, nokuba isalathiso sibambekile kwaye sihleli xa sishukuma, kwaye usebenzise i-potentiometer ukulungisa imbonakalo yeemagnethi, i-demagnetization, ukwandiswa kwecingo, kunye ne-shrapnel Ukwenyuka kweempazamo ezibangelwa kukudinwa, umonakalo wokulinganisela, njl.
