Izinto Ezithinta Impilo Yesevisi ye-Molybdenum Electrodes

 Imboni yengilazi iyimboni yendabuko esebenzisa amandla aphezulu. Ngenani eliphezulu lamandla ezinto ezimbiwa phansi kanye nokuthuthukiswa kwezidingo zokuvikela imvelo, ubuchwepheshe bokuncibilika bushintshile kusukela kubuchwepheshe bokushisa ilangabi bendabuko kuya kubuchwepheshe bokuncibilika kukagesi. I-electrode iyisici esithintana ngokuqondile noketshezi lwengilazi futhi idlulisele amandla kagesi oketshezini lwengilazi, okuyisisetshenziswa esibalulekile ku-electrofusion yengilazi.

 

I-Molybdenum electrode iyisici esibalulekile se-electrode ku-electrofusion engilazi ngenxa yamandla ayo okushisa aphezulu, ukumelana nokugqwala, kanye nobunzima bokwenza imibala yengilazi. Kuthemba ukuthi impilo yesevisi ye-electrode izoba inqobo nje uma kuhhavini noma ngisho nangaphezu kweminyaka yokushisa, kodwa i-electrode izovame ukulimala ngesikhathi sokusetshenziswa kwangempela. Kubaluleke kakhulu ukuthi uqonde ngokugcwele izici ezihlukahlukene ezithonya impilo yesevisi yama-electrode e-molybdenum ku-electro-fusion yengilazi.

 

 

I-Oxidation ye-Molybdenum Electrode

I-electrode ye-molybdenum inezici zokumelana nezinga lokushisa eliphezulu, kodwa isabela nomoya-mpilo emazingeni okushisa aphezulu. Lapho izinga lokushisa lifinyelela ku-400 ℃, i-i-molybdenumizoqala ukwakha i-molybdenum oxidation (MoO) kanye ne-molybdenum disulfide (MoO2), engakwazi ukunamathela ebusweni be-molybdenum electrode futhi yakhe ungqimba lwe-oxide, futhi ihlele i-oxidation eyengeziwe ye-molybdenum electrode. Lapho izinga lokushisa lifinyelela ku-500 ℃ ~ 700 ℃, i-molybdenum izoqala i-oxidizing ibe yi-molybdenum trioxide (MoO3). Kuyigesi eguquguqukayo, ecekela phansi ungqimba oluvikelayo lwe-oxide yasekuqaleni ukuze indawo entsha evezwe i-electrode ye-molybdenum iqhubeke ne-oxidize yakhe i-MoO3. I-oxidation ephindaphindiwe kanjalo nokuvuthwa kwenza i-electrode ye-molybdenum iqhubeke iguguleka ize ilimale ngokuphelele.

 

Ukusabela kwe-Molybdenum Electrode ku-Component ku-Glass

I-electrode ye-molybdenum isabela nezinye izingxenye noma ukungcola engxenyeni yengilazi emazingeni okushisa aphezulu, okubangela ukuguguleka okukhulu kwe-electrode. Isibonelo, isixazululo sengilazi esine-As2O3, Sb2O3, ne-Na2SO4 njengesicacisi sibucayi kakhulu ekugugulekeni kwe-electrode ye-molybdenum, ezofakwa i-oxidized ku-MoO ne-MoS2.

 

Ukusabela kwe-Electrochemical ku-Glass Electrofusion

Ukusabela kwe-electrochemical kwenzeka ku-electrofusion yengilazi, esendaweni yokuxhumana phakathi kwe-molybdenum electrode nengilazi encibilikisiwe. Emjikelezweni wengxenye ephozithivu yokuphakelwa kwamandla kagesi we-AC, ama-ion omoya-mpilo anegethivu adluliselwa ku-electrode ephozithivu ukuze kudedelwe ama-electron, akhulula umoya-mpilo ukuze abangele i-oxidation ye-electrode ye-molybdenum. Emjikelezweni wokuphakelwa kwamandla kagesi we-AC onegethivu yesigamu somjikelezo, amanye ama-cations ancibilikayo engilazi (njenge-boron) azothuthela ku-electrode eyinegethivu kanye nokukhiqizwa kwenhlanganisela ye-molybdenum electrode, okungamadiphozithi axegayo endaweni ye-electrode ukuze kulimaze i-electrode.

 

Izinga lokushisa nokuminyana kwamanje

Izinga lokuguguleka kwe-molybdenum electrode liyakhula ngokunyuka kwezinga lokushisa. Uma ukwakheka kwengilazi nezinga lokushisa lenqubo kuzinzile, ukuminyana kwamanje kuba yisici esilawula izinga lokugqwala kwe-electrode. Nakuba ukuminyana okuphezulu okuvunyelwe kwamanje kwe-electrode ye-molybdenum kungafinyelela ku-2~3A/cm2, ukuguguleka kwe-electrode kuzokwenyuka uma i-current enkulu isebenza.
