Niaj hnub no, peb yuav qhia rau koj Q & A ntawm cov kev paub yooj yim ntawm electrolytic polishing nyob rau hauv txhua hnub electroplating ua thiab ntau lawm. Cov hauv qab no yog 25 Q&A cov ntsiab lus ntawm cov kev paub yooj yim ntawm electrolytic polishing ua ntej electroplating. Peb vam tias yuav pab electroplating masters nyob ib puag ncig peb.
Lub workpiece ua hauj lwm ua tus anode txuas mus rau tus ncej zoo ntawm DC fais fab mov. Siv cov khoom siv hluav taws xob uas tiv taus electrolyte corrosion xws li hlau lead thiab stainless hlau ua cathodes thiab txuas mus rau qhov tsis zoo electrode ntawm DC fais fab mov. Qhov ob yog raus rau hauv ib qho electrolyte (feem ntau yog tsim los ntawm sulfuric acid thiab phosphoric acid) ntawm qhov sib nrug. Ntawm qhov kub thiab txias, qhov hluav taws xob, thiab qhov ceev tam sim no (feem ntau tsawg dua 1 ampere / cm2), qhov me me ntawm qhov chaw ntawm lub workpiece yaj ua ntej thiab maj mam dhau los ua tus du thiab ci ntsa iab tom qab tau hluav taws xob rau qee lub sijhawm (feem ntau. kaum vib nas this mus rau ob peb feeb).
Cov yam ntxwv ntawm electrolytic polishing
① Cov polished nto yuav tsis tsim cov txheej txheem metamorphic, tsis muaj kev ntxhov siab ntxiv, thiab tuaj yeem tshem tawm lossis txo cov txheej txheem kev ntxhov siab.
② Muaj peev xwm ua cov ntaub ntawv nyuaj thiab mos uas nyuaj rau tshuab polished, nrog rau nyias-walled, complex, thiab me me thiab cov khoom
③ Lub sijhawm polishing luv thiab lub peev xwm los txhuam ntau daim ib txhij, ua rau muaj kev ua haujlwm siab
④ Qhov saum npoo roughness ua tiav los ntawm electrolytic polishing muaj feem xyuam rau qhov qub nto roughness thiab feem ntau tuaj yeem txhim kho los ntawm ob theem. Txawm li cas los xij, vim qhov tsis zoo thoob ntiaj teb, kev pabcuam luv luv, thiab muaj zog corrosiveness ntawm electrolytes, daim ntawv thov ntau ntawm electrolytic polishing yog txwv. Electrolytic polishing yog tsuas yog siv rau cov khoom siv hlau thiab qhov chaw uas tsis tshua muaj qhov roughness, xws li reflectors, stainless hlau tableware, decorations, koob txhaj tshuaj, springs, hniav, thiab stainless hlau kav. Nws kuj tseem siv tau rau polishing tej pwm (xws li kua nplaum ntoo pwm thiab iav pwm) thiab metallographic sib tsoo discs.
