EP chubhu ndeimwe yezvigadzirwa zvikuru zvekambani. Maitiro ayo makuru ndeekupukuta mukati mechubhu nemagetsi zvichibva pamachubhu akajeka.
I cathode, uye matanda maviri aya anonyudzwa panguva imwe chete mu electrolytic cell ine voltage ye 2-25 volts. Kushanda kwe current kunokonzera makemikari akasimba uye kuparadzwa kweanodic. Kazhinji, nzvimbo yepamusoro yesimbi inotanga yanyungudutswa panguva ye electropolishing, kuitira kuti pave nemhedzisiro yekuwedzera kupenya kwenzvimbo yebasa.
Zvinhu zvikuru zvekupolisha nemagetsi zvinosanganisira tembiricha ye electrolyte, amplitude ye cathode (daro riri pakati pe cathode ne workpiece inofanira kuporishwa), huwandu hwe acid solution, uye nguva ye electrolysis. Mumamiriro ezvinhu akajairwa, nguva yekuti chinhu chakaiswa nemagetsi chinyikwe mu electrolytic tank inotarwa zvichienderana nehunhu hwe workpiece iri kukandwa. Munguva pfupi yakabviswa.
Kuchenesa nemagetsi kunogona kuwedzera kuramba kwengura pamusoro pemapaipi esimbi isingatsvi uye kuve nechokwadi chekuti ruvara rwemukati nerwekunze rwunogara rwakafanana; kuchenesa nemagetsi kunogona kuratidza zvikanganiso zvepadenga zvinoonekwa, izvo zvinogona kuderedza nzvimbo yemukati yesimbi isingatsvi, kuwedzera kutsvinda kwepadenga, uye kuita kuti michina iwanikwe. Kuchenesa nekukurumidza uye zvinobudirira uye kubvisa zvinobudirira maburi epadenga anokonzerwa nekupukuta kwemuchina izvo zvinogona kukonzera kuoxidation kwesimbi uye kuchinja kweruvara.
Kupolisha nemagetsi kunobvisa ma ions esimbi asina kuchena pamusoro, izvo zvinobatsira kuwedzera Cr/Fe ratio pamusoro, kuwedzera passivation protection layer, uye kuderedza njodzi ye red rust mu system. Kupolisha nemagetsi kwakapfava uye kwakapfava kupfuura kupolisha nemagetsi. Saka, "ASME BPE" inoda kuti ukobvu hwe passivation layer ye electrolytic polishing husafanirwe kunge huri pasi pe15Å.
Zhongrui inoshandisa kuchenesa kwemakemikari e ultrasonic kuti ienderane nezvinodiwa zveASTM G93 kana SEMI E49.6. Mushure mekunge chubhu yakachena kwazvo yacheneswa nemvura yakachena ye18MΩ yakabviswa ioni, chubhu yakacheneswa inofuridzwa negesi yenitrogen yakachena ye99.999%, yozadzwa muchubhu, uye yoiswa muimba yakachena.
Panguva imwe chete, Zhongrui yakavaka imba yakachena isina guruva yeISO14644-1 Class 5 mufekitori yechipiri yekurongedza machubhu eEP.
Mutsetse wekugadzira weZhongrui we electrolytic polishing wapasa bvunzo iyi uye wakagadzirwa zvakanyanya uye wakapihwa kunyika dzemuno nedzekunze. Kambani iyi inoronga kuwedzera mutsetse wekugadzira uye kuwedzera kugadzirwa kwemapombi eEP.
Parizvino, zvinodiwa zvemapaipi eEP anogadzirwa neZhongrui zvinotangira paO.D1/4"-40A, mwero wekushandisa unoenderana neASTM269, uye kuomarara kwemukati mepamusoro kunogona kusvika pasi peRa0.25um. Kune maindasitiri akawanda mumusika weChina, akadai seindasitiri yesemiconductor, laboratori, simba rezuva. Indasitiri yekugadzira nemisika yekunze iri kuwedzerawo, senge Singapore, Malaysia, neThailand.
