Zvinhu Zvinokanganisa Hupenyu hweSevhisi yeMolybdenum Electrodes

 Indasitiri yegirazi iindasitiri yechinyakare ine simba guru rekushandisa. Nemutengo wepamusoro wefossil simba uye kuvandudzwa kwezvinodiwa zvekuchengetedza kwezvakatipoteredza, tekinoroji yekunyunguduka yachinja kubva pachinyakare murazvo wekudziya tekinoroji kuenda kumagetsi ekunyungudika tekinoroji. Elekitirodhi ndicho chinhu chinobata zvakanangana negirazi remvura uye chinopfuudza simba remagetsi kumvura yegirazi, inova midziyo yakakosha mugirazi remagetsi.

 

Molybdenum electrode chinhu chakakosha che electrode mugirazi electrofusion nekuda kwesimba rayo repamusoro-tembiricha, kusaita ngura, uye kuomerwa kwekugadzira ruvara rwegirazi. Zvinotarisirwa kuti hupenyu hwebasa hwe electrode huchange hwakareba sezera remoto kana kunyange kupfuura zera remoto, asi electrode inowanzokuvadzwa panguva yekushandiswa chaiyo. Izvo zvakakosha zvakakosha kuti unzwisise zvizere zvakasiyana-siyana zvinopesvedzera zvinhu zvehupenyu hwesevhisi ye molybdenum electrodes mugirazi electro-fusion.

 

 

Oxidation yeMolybdenum Electrode

Iyo molybdenum electrode ine maitiro ekupisa-kupisa, asi inopindirana neokisijeni pakupisa kwakanyanya. Kana tembiricha yasvika 400 ℃, iyomolybdenumichatanga kuumba molybdenum oxidation (MoO) uye molybdenum disulfide (MoO2), iyo inogona kunamatira pamusoro pe molybdenum electrode uye kuumba oxide layer, uye kuronga kuwedzera kwe oxidation ye molybdenum electrode. Kana tembiricha yasvika 500 ℃ ~ 700 ℃, molybdenum inotanga oxidizing kune molybdenum trioxide (MoO3). Igasi rinoputika, rinoparadza chidziviriro che oxide yepakutanga kuitira kuti hutsva hutsva hunobudiswa ne molybdenum electrode hunoramba huine oxidize kuumba MoO3. Kwakadaro kudzokororwa oxidation uye volatilization kunoita kuti molybdenum electrode irambe ichikukurwa kusvika yaparara zvachose.

 

Kuita kweMolybdenum Electrode kune Iyo Chikamu muGirazi

Iyo molybdenum electrode inopindirana nezvimwe zvikamu kana tsvina muchikamu chegirazi pakudziya kwakanyanya, zvichikonzera kukukurwa kwakanyanya kwe electrode. Semuyenzaniso, mhinduro yegirazi ine As2O3, Sb2O3, uye Na2SO4 seanojekesa akanyanya kuoma pakukukurwa kwemolybdenum electrode, inozove oxidized kuMoO neMoS2.

 

Electrochemical Reaction muGlass Electrofusion

Iyo electrochemical reaction inoitika mugirazi electrofusion, iyo iri pakusangana pakati pe molybdenum electrode negirazi rakanyungudutswa. Muchikamu chakanaka chechidimbu chemagetsi eAC, maion eokisijeni asina kunaka anoendeswa kune electrode yakanaka kuti ibudise maerekitironi, ayo anoburitsa okisijeni kuti ikonzerese kusvibiswa kweelectrode yemolybdenum. Mune AC simba rekupa negative half cycle, mamwe egirazi anonyunguduka cations (senge boron) anoenda kune negative electrode uye chizvarwa chemolybdenum electrode compounds, ayo ari loose deposits mu electrode surface kukuvadza electrode.

 

Tembiricha uye ikozvino density

Mwero wekukukurwa kwe molybdenum electrode unowedzera nekuwedzera kwekushisa. Kana iyo girazi kuumbwa uye tembiricha yemaitiro yakagadzikana, density iripo inova chinhu chinodzora corrosion rate ye electrode. Kunyange zvazvo iyo yakawanda inobvumirwa ikozvino density ye molybdenum electrode inogona kusvika 2 ~ 3A / cm2, iyo electrode erosion ichawedzerwa kana yakakura ikozvino ichishanda.
