EP chubu ndi chimodzi mwazinthu zazikulu zamakampani. Njira yake yayikulu ndikupukuta kwamagetsi mkati mwa chubu pamaziko a machubu owala.
Ndi cathode, ndipo mizati iwiri imodzi kumizidwa mu selo electrolytic ndi voteji 2-25 volts. Zochita zapano zimabweretsa mphamvu yamankhwala komanso kusungunuka kwa anodic. Kawirikawiri, malo apamwamba kwambiri azitsulo amayamba kusungunuka panthawi ya electropolishing, kuti akwaniritse zotsatira zowonjezera kuwala kwapamwamba kwa workpiece.
Zinthu zazikuluzikulu za electropolishing zimaphatikizapo kutentha kwa electrolyte, matalikidwe a cathode (mtunda pakati pa cathode ndi workpiece kuti upukutidwe), kuchuluka kwa asidi, ndi nthawi ya electrolysis. Nthawi zonse, kutalika kwa nthawi yoti chinthu cha electrolyzed chilowerere mu thanki ya electrolytic chimatsimikiziridwa molingana ndi mawonekedwe a workpiece akuponyedwa. m'nthawi yochepa adatulutsidwa.
Electropolishing akhoza kuonjezera kukana dzimbiri pamwamba pa mipope zosapanga dzimbiri ndi kuonetsetsa mosasinthasintha mkati ndi kunja mtundu; electropolishing akhoza kuwulula zooneka wapezeka pamwamba zilema, amene angathe kuchepetsa m`kati pamwamba dera zitsulo zosapanga dzimbiri, kuonjezera kusalala pamwamba, ndi atsogolere kuzindikira zida Mwachangu ndi kothandiza kuyeretsa ndi kuchotsa mogwira protrusions pamwamba chifukwa cha kupukuta makina amene angayambitse chitsulo okosijeni ndi kusinthika.
Electropolishing imachotsa ma ion achitsulo aulere pamtunda, zomwe zimathandiza kuonjezera chiŵerengero cha Cr / Fe pamtunda, kupititsa patsogolo chitetezo cha passivation, ndi kuchepetsa chiopsezo cha dzimbiri lofiira mu dongosolo. Electrolytic polishing ndi yosalala komanso yosalala kuposa kupukuta kwamakina. Choncho, "ASME BPE" amafuna kuti makulidwe a passivation wosanjikiza wa electrolytic kupukuta sayenera kuchepera 15Å.
Zhongrui amatenga akupanga mankhwala kuyeretsa kuti akwaniritse zofunikira za ASTM G93 kapena SEMI E49.6. chubu choyeretsedwa kwambiri chikatsukidwa ndi madzi a 18MΩ opangidwa ndi deionized ultrapure, chubu choyeretsedwacho chimawomberedwa ndi mpweya wa nayitrogeni wa 99.999%, wodzazidwa mu chubu, ndikuyikidwa mchipinda choyera.
Nthawi yomweyo, Zhongrui adamanga chipinda choyera cha ISO14644-1 Class 5 chopanda fumbi mu fakitale yachiwiri yopakira machubu a EP.
Mzere wopanga ma electrolytic polishing wa Zhongrui wapambana mayeso ndipo wapangidwa mochuluka ndikuperekedwa kumayiko akunyumba ndi akunja. Kampaniyo ikukonzekera kuwonjezera mzere wopanga ndikukulitsa kupanga mapaipi a EP.
Pakalipano, mafotokozedwe a mapaipi a EP opangidwa ndi Zhongrui amachokera ku O.D1 / 4 "-40A, ndondomeko yoyendetsera ntchito ikugwirizana ndi ASTM269, ndipo kuuma kwamkati kumafika pansi pa Ra0.25um. Pali mafakitale ambiri ku China. msika, monga mafakitale a semiconductor, labotale, mphamvu ya dzuwa Makampani opanga ndi misika yakunja ikukulanso, monga Singapore, Malaysia, ndi Thailand.
