EP raj yog ib lub tuam txhab cov khoom tseem ceeb. Nws cov txheej txheem tseem ceeb yog electrolytically polish lub puab nto ntawm lub raj ntawm lub hauv paus ntawm lub teeb ci.
Nws yog ib tug cathode, thiab ob tug ncej yog ib txhij rau hauv lub electrolytic cell nrog ib tug voltage ntawm 2-25 volts. Qhov kev txiav txim ntawm tam sim no ua rau muaj zog tshuaj tiv thaiv thiab xaiv anodic dissolution. Feem ntau, qhov siab tshaj plaws ntawm cov hlau nto yog thawj zaug yaj thaum lub sij hawm electropolishing, thiaj li ua tiav cov nyhuv ntawm kev ua kom lub ntsej muag ci ntawm lub workpiece.
Cov yam tseem ceeb ntawm electropolishing muaj xws li qhov kub ntawm cov electrolyte, lub amplitude ntawm cathode (qhov kev ncua deb ntawm lub cathode thiab lub workpiece yuav polished), lub concentration ntawm cov kua qaub, thiab lub sij hawm electrolysis. Nyob rau hauv ib txwm muaj xwm txheej, lub sijhawm ntev ntawm cov khoom siv electrolyzed yuav tsum tau tsau rau hauv lub tank electrolytic yog txiav txim siab raws li cov yam ntxwv ntawm lub workpiece raug pov. nyob rau hauv ib lub sij hawm luv luv raug coj tawm.
Electropolishing tuaj yeem ua rau muaj kev tiv thaiv corrosion ntawm qhov chaw ntawm cov kav dej stainless hlau thiab xyuas kom muaj xim zoo ib yam sab hauv thiab sab nrauv; electropolishing tuaj yeem qhia pom qhov pom pom qhov tsis xws luag, uas tuaj yeem txo qhov chaw sab hauv ntawm cov hlau tsis huv, ua kom lub ntsej muag du, thiab pab txhawb kev ua kom pom tseeb ntawm cov cuab yeej ceev thiab kev tu kom zoo thiab kev tshem tawm ntawm qhov chaw tawm los ntawm cov tshuab polishing uas tuaj yeem ua rau hlau oxidation thiab kev hloov xim.
Electropolishing tshem tawm cov hlau ions dawb rau ntawm qhov chaw, uas yuav pab ua kom cov Cr / Fe piv rau saum npoo, txhim khu cov txheej tiv thaiv passivation, thiab txo qhov kev pheej hmoo ntawm xeb liab hauv lub cev. Electrolytic polishing yog smoother thiab flatter dua mechanical polishing. Yog li ntawd, "ASME BPE" xav kom lub thickness ntawm passivation txheej ntawm electrolytic polishing yuav tsum tsis txhob tsawg tshaj li 15Å.
Zhongrui txais cov tshuaj ntxuav ultrasonic kom ua tau raws li cov cai ntawm ASTM G93 lossis SEMI E49.6. Tom qab lub raj ultra-ntxuav yog ntxuav los ntawm 18MΩ deionized ultrapure dej, lub raj purified yog tshuab nrog high-purity nitrogen gas ntawm 99.999%, ntim rau hauv lub raj, thiab ntim rau hauv ib chav huv si.
Nyob rau tib lub sijhawm, Zhongrui tau tsim ISO14644-1 Chav Kawm 5 chav tsis muaj plua plav huv hauv lub Hoobkas thib ob rau ntim EP raj.
Zhongrui's electrolytic polishing ntau lawm kab tau dhau qhov kev sim thiab tau tsim ntau thiab xa mus rau cov teb chaws thiab txawv teb chaws. Lub tuam txhab npaj yuav ua kom cov kab ntau lawm thiab nthuav cov EP cov kav dej.
Tam sim no, cov kev qhia tshwj xeeb ntawm EP cov kav dej tsim los ntawm Zhongrui ntau yam ntawm O.D1 / 4 "-40A, tus qauv kev siv yog raws li ASTM269, thiab lub puab nto roughness tuaj yeem ncav cuag hauv qab Ra0.25um. Muaj ntau qhov kev lag luam hauv Suav. kev lag luam, xws li kev lag luam semiconductor, chav kuaj, hnub ci zog Kev lag luam thiab kev lag luam txawv teb chaws kuj nthuav dav, xws li Singapore, Malaysia, thiab Thaib teb.
