1.Dab tsi yog qhov tseem ceeb mechanism?
Thaum cov phaj energized reacts nrog cov tshuaj alkaline, muaj zog electrolytic cov tshuaj tiv thaiv tshwm sim nyob rau saum npoo ntawm steel sawb, tsim ib tug loj npaum li cas ntawm cov pa roj, uas yog lub zog tsav ntawm tag nrho cov txheej txheem tu.
Cov tshuaj tiv thaiv cathode: Thaum cov hlau sawb ua raws li cov cathode, txo cov tshuaj tiv thaiv tshwm sim ntawm qhov chaw, tso tawm ntau cov npuas me me hydrogen.
Reaction formula: 2H⁺ + 2e⁻ → H₂↑
Cov tshuaj tiv thaiv Anodic: Thaum cov hlau sawb ua raws li cov anode, cov tshuaj tiv thaiv oxidation tshwm sim ntawm qhov chaw, tso cov pa npuas loj dua.
Reaction formula: 4OH⁻ - 4e⁻ → 2H₂O + O₂↑
2.Dab tsi muaj kev nkag tau yooj yim nta?
Dhau li ntawm degreasing, electrolytic tu muaj lwm txoj haujlwm zais. Nyob rau hauv cov txheej txheem no, cov hlau sawb ua raws li cathode, txo cov silicates nyob rau hauv cov tshuaj ntxuav thiab tso ib tug iav dielectric zaj duab xis kwv yees li 2.3 nanometers tuab ntawm nws nto. Cov yeeb yaj kiab no yog qhov tseem ceeb, vim tias nws tiv thaiv cov hlau kauj los ntawm kev ua ke ntawm cov khaubncaws sab nraud povtseg vim qhov kub thiab txias thaum lub sij hawm tom qab annealing txheej txheem, yog li xyuas kom cov khoom zoo.
3.Vim li cas electrolytic tu zoo dua?
Kev tu tshuaj lom neeg feem ntau yog nyob ntawm cov nyhuv emulsifying ntawm surfactants kom yaj lossis tshem cov roj stains los ntawm cov phaj hlau. Nws txoj kev ua tau zoo yog txwv rau cov dents los yog nruj nreem khi stains.
Electrolytic tu, tsim raws li cov txheej txheem tshuaj, suav nrog kev cuam tshuam thiab tev tawm los ntawm ntau cov pa npuas. Raws li cov npuas no tsim, loj hlob, thiab tshem tawm los ntawm cov hlau nto, lawv txuas ntxiv cuam tshuam rau cov yeeb yaj kiab roj, txawm tias "thawb" tawm cov kab mob uas muab zais rau hauv qhov chaw me me. Yog li ntawd, nws txoj kev txhim kho hauv qhov huv si yog qhov tsis sib xws los ntawm kev siv tshuaj ntxuav.
4.Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm kev ntxuav cathode (hydrogen evolution)?
Kev ua haujlwm siab. Hydrogen npuas yog me me thiab ntau, nrog rau qhov loj tag nrho cheeb tsam, uas ua rau muaj peev xwm nqa tau cov roj thiab emulsify, ua rau muaj kev tu ntau dua.
Lub generated atomic hydrogen tuaj yeem nkag mus rau hauv cov hlau matrix, ua rau hydrogen embrittlement (ua rau cov hlau nkig) thiab cuam tshuam rau nws cov khoom siv kho tshuab.
5.Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm kev ntxuav anodic (oxygen evolution)?
Nws tshem tawm txoj kev pheej hmoo ntawm hydrogen embrittlement thiab nta cov pa npuas loj nrog ib qho muaj zog -unit nqa peev xwm, ua kom nws tshem tawm cov khoom zoo xws li hlau hmoov los ntawm qhov chaw ntawm cov hlau.
Kev tu kom zoo yog qhov tsawg, thiab corrosion rau cov khoom siv (anode phaj) kuj muaj zog dua.
