Chubu cha EP

Chubu cha EP ndi chimodzi mwa zinthu zazikulu za kampaniyo. Njira yake yayikulu ndikupukuta mkati mwa chubu pogwiritsa ntchito machubu owala.

Ndi cathode, ndipo mitengo iwiriyi imamizidwa nthawi imodzi mu selo ya electrolytic ndi voltage ya 2-25 volts. Kachitidwe ka mphamvu yamagetsi kamayambitsa mphamvu ya mankhwala komanso kusungunuka kwa anodic. Nthawi zambiri, malo apamwamba kwambiri pamwamba pa chitsulo amayamba kusungunuka panthawi ya electropolishing, kuti akwaniritse zotsatira za kuwonjezera kuwala pamwamba pa workpiece.

Zinthu zofunika kwambiri pakupukuta ndi electrolyte ndi monga kutentha kwa electrolyte, kutalika kwa cathode (mtunda pakati pa cathode ndi workpiece yoti ipukutidwe), kuchuluka kwa asidi, ndi nthawi ya electrolysis. Nthawi zonse, nthawi yomwe chinthu chopangidwa ndi electrolyze chilowerere mu thanki ya electrolytic imatsimikiziridwa malinga ndi mawonekedwe a workpiece yomwe ikuponyedwa. Munthawi yochepa idachotsedwa.

Kupukuta ndi electromagnetic kungathandize kuletsa dzimbiri pamwamba pa mapaipi achitsulo chosapanga dzimbiri ndikuwonetsetsa kuti utoto wamkati ndi wakunja umakhala wofanana; kupukuta ndi electromagnetic kungathandize kuzindikira zolakwika zomwe zapezeka pamwamba, zomwe zingathandize kuchepetsa bwino malo amkati mwa chitsulo chosapanga dzimbiri, kuwonjezera kusalala kwa pamwamba, komanso kuthandizira kupangidwa kwa zida. Kuyeretsa mwachangu komanso moyenera komanso kuchotsa bwino zinthu zomwe zimachitika pamwamba chifukwa cha kupukuta kwamakina zomwe zingayambitse kusungunuka kwa chitsulo ndi kusintha mtundu.

Kupukuta kwa electrolytic kumachotsa ma ayoni achitsulo omasuka pamwamba, zomwe zimathandiza kuwonjezera chiŵerengero cha Cr/Fe pamwamba, kukulitsa gawo loteteza ku kusuntha, ndikuchepetsa chiopsezo cha dzimbiri lofiira mu dongosolo. Kupukuta kwa electrolytic kumakhala kosalala komanso kosalala kuposa kupukuta kwamakina. Chifukwa chake, "ASME BPE" imafuna kuti makulidwe a gawo losuntha la kusuntha kwa electrolytic polishing asapitirire 15Å.

Zhongrui imagwiritsa ntchito kuyeretsa kwa mankhwala opangidwa ndi ultrasonic kuti ikwaniritse zofunikira za ASTM G93 kapena SEMI E49.6. Pambuyo poti chubu choyera kwambiri chiyeretsedwa ndi madzi oyera a 18MΩ, chubu choyeretsedwacho chimapukutidwa ndi mpweya wa nayitrogeni woyera kwambiri wa 99.999%, wodzazidwa mu chubucho, ndikupakidwa m'chipinda choyera.

Pa nthawi yomweyo, Zhongrui anamanga chipinda choyera cha ISO14644-1 Class 5 chopanda fumbi mu fakitale yachiwiri yopangira machubu a EP.
