EP chubhu chimwe chezvigadzirwa zvikuru zvekambani. Maitiro ayo makuru ndeye electrolytically polish yemukati mechubhu pahwaro hwemachubhu akajeka.
Ndiyo cathode, uye matanda maviri panguva imwe chete akanyudzwa musero re electrolytic nemhepo ye 2-25 volts. Chiito chezvino chinokonzera kusimba kwemakemikari kuita uye kusarudza anodic dissolution. Kazhinji, iyo yepamusoro yepamusoro yesimbi yepamusoro inotanga kunyungudutswa panguva ye electropolishing, kuitira kuti iwane mhedzisiro yekuwedzera kupenya kwepamusoro kweiyo workpiece.
Zvinhu zvakakosha zve electropolishing zvinosanganisira tembiricha ye electrolyte, amplitude yecathode (chinhambwe chiri pakati pecathode uye workpiece inofanira kukwenenzverwa), kusungirirwa kweasidhi mhinduro, uye nguva ye electrolysis. Mumamiriro ezvinhu akajairwa, hurefu hwenguva yekuti chinhu chine electrolyzed chinyuswe mutangi re electrolytic inotarwa zvichienderana nehunhu hwechishandiso chiri kukandwa. munguva pfupi yakabudiswa.
Electropolishing inogona kuwedzera kushorwa kwepamusoro pepombi dzesimbi isina tsvina uye kuve nechokwadi chekuenderana mukati uye kunze kwemavara; electropolishing inogona kuratidza zvinoonekwa zvakaonekwa zvisizvo zvepasi, izvo zvinogona kunyatso kudzikisa nzvimbo yemukati yesimbi isina tsvina, kuwedzera kutsetseka kwepamusoro, uye kufambisa kuitika kwemidziyo Kukurumidza uye kwakanyatso kuchenesa uye kunobudirira kubviswa kwepamusoro protrusions kunokonzerwa ne mechanical polishing iyo inogona kukonzera iron oxidation uye discoloration.
Electropolishing inobvisa mahara iron ions pamusoro, iyo inobatsira kuwedzera chiyero cheCr / Fe pamusoro, kuwedzera passivation kuchengetedza layer, uye kuderedza njodzi yekutsvuka ngura muhurongwa. Electrolytic polishing yakapfava uye yakapfava pane kupukuta kwemuchina. Naizvozvo, "ASME BPE" inoda kuti ukobvu hwepassivation layer ye electrolytic polishing haifanire kunge iri pasi pe15Å.
Zhongrui inotora ultrasonic kemikari yekuchenesa kuti isangane nezvinodiwa zveASTM G93 kana SEMI E49.6. Mushure mekunge iyo yakanyanya-yakachena chubhu yacheneswa ne18MΩ deionized ultrapure mvura, chubhu yakacheneswa inofuridzirwa nepamusoro-kuchena nitrogen gasi re99.999%, yakazadzwa muchubhu, uye yakaputirwa muimba yakachena.
Panguva imwecheteyo, Zhongrui akavaka ISO14644-1 Kirasi 5-isina huruva kamuri mufekitori yechipiri yekurongedza EP machubhu.
Zhongrui's electrolytic polishing production line yapasa bvunzo uye yave yakawanda-yakagadzirwa uye yakapihwa kunyika dzemumba nekune dzimwe nyika. Iyo kambani inoronga kuwedzera mutsara wekugadzira uye kuwedzera kugadzirwa kweEP mapaipi.
Parizvino, zvirevo zveEP mapaipi anogadzirwa neZhongrui anobva kuO.D1 / 4 "-40A, chiyero chekushandisa chinopindirana neASTM269, uye mukati mepamusoro roughness inogona kusvika pasi peRa0.25um. Kune akawanda maindasitiri mumusika weChina, semiconductor indasitiri, laboratory, solar energy Indasitiri yekugadzira, Malaysia zvakare, misika yekugadzira uye Malaysia.
