EP raj yog ib qho ntawm cov khoom tseem ceeb ntawm lub tuam txhab. Nws cov txheej txheem tseem ceeb yog electrolytically polish sab hauv ntawm lub raj raws li cov raj ci.
Nws yog ib lub cathode, thiab ob lub ncej tau muab tso rau hauv lub electrolytic cell tib lub sijhawm nrog lub zog hluav taws xob ntawm 2-25 volts. Qhov kev ua ntawm tam sim no ua rau muaj kev tshuaj lom neeg muaj zog thiab kev yaj anodic xaiv. Feem ntau, qhov chaw siab tshaj plaws ntawm cov hlau nto yog yaj thawj zaug thaum lub sijhawm electropolishing, yog li ua tiav cov txiaj ntsig ntawm kev ua kom qhov ci ntsa iab ntawm qhov workpiece.
Cov yam tseem ceeb ntawm electropolishing suav nrog qhov kub ntawm cov electrolyte, qhov loj ntawm cathode (qhov deb ntawm cathode thiab qhov workpiece kom tau polished), qhov concentration ntawm cov kua qaub, thiab lub sijhawm electrolysis. Nyob rau hauv cov xwm txheej ib txwm muaj, lub sijhawm ntev npaum li cas rau cov tshuaj electrolyzed kom tau ntub rau hauv lub tank electrolytic yog txiav txim siab raws li cov yam ntxwv ntawm qhov workpiece raug pov tseg. hauv lub sijhawm luv luv tau coj tawm.
Kev siv hluav taws xob electropolishing tuaj yeem ua rau kom muaj kev tiv thaiv corrosion ntawm qhov chaw ntawm cov kav dej hlau tsis xeb thiab xyuas kom meej tias xim sab hauv thiab sab nraud sib xws; electropolishing tuaj yeem qhia tau qhov tsis zoo ntawm qhov chaw pom, uas tuaj yeem txo qhov chaw sab hauv ntawm cov hlau tsis xeb, ua rau qhov chaw du, thiab pab txhawb kev ua tiav ntawm cov khoom siv. Kev ntxuav sai thiab zoo thiab tshem tawm cov nplaim tawm uas tshwm sim los ntawm kev siv tshuab polishing uas tuaj yeem ua rau hlau oxidation thiab discoloration.
Kev siv hluav taws xob tshem tawm cov hlau dawb ions ntawm qhov chaw, uas pab ua kom Cr/Fe piv ntawm qhov chaw, txhim kho txheej tiv thaiv passivation, thiab txo qhov kev pheej hmoo ntawm xeb liab hauv lub kaw lus. Kev txhuam electrolytic yog du thiab tiaj dua li kev txhuam tshuab. Yog li ntawd, "ASME BPE" yuav tsum tau kom qhov tuab ntawm txheej passivation ntawm electrolytic polishing yuav tsum tsis pub tsawg dua 15Å.
Zhongrui siv cov tshuaj ntxuav ultrasonic los ua kom tau raws li qhov yuav tsum tau ua ntawm ASTM G93 lossis SEMI E49.6. Tom qab lub raj xa dej huv si raug ntxuav los ntawm 18MΩ deionized ultrapure dej, lub raj lim dej raug tshuab nrog cov pa roj nitrogen siab huv si ntawm 99.999%, sau rau hauv lub raj, thiab ntim rau hauv chav huv si.
Tib lub sijhawm, Zhongrui tau tsim chav huv ISO14644-1 Class 5 tsis muaj plua plav hauv lub Hoobkas thib ob rau kev ntim cov raj EP.
Zhongrui cov kab ntau lawm electrolytic polishing tau dhau qhov kev xeem thiab tau tsim ntau thiab xa mus rau cov teb chaws hauv tsev thiab txawv teb chaws. Lub tuam txhab npaj yuav nce cov kab ntau lawm thiab nthuav cov kav dej EP.
Tam sim no, cov lus qhia ntawm cov kav dej EP uas Zhongrui tsim tawm ntau ntawm O.D1 / 4 "-40A, tus qauv siv yog raws li ASTM269, thiab qhov roughness sab hauv tuaj yeem ncav cuag qis dua Ra0.25um. Muaj ntau yam kev lag luam hauv kev lag luam Suav teb, xws li kev lag luam semiconductor, chaw kuaj mob, lub zog hnub ci Kev lag luam tsim khoom thiab kev lag luam txawv teb chaws kuj tseem nthuav dav, xws li Singapore, Malaysia, thiab Thaib teb.
