· Kev txhuam hniav yog ib qho txheej txheem los ntawm sab saud mus rau hauv qab, lub cev. Nws ua rau cov xim pleev, txiav, thiab ua rau qhov chaw du thiab du. Nws zoo heev ntawm kev ua tiav Ra qis heev (ua tiav daim iav) tab sis tuaj yeem tso cov khoom tsis huv, cov qauv me me hloov pauv, thiab kev ntxhov siab seem.
· Electropolishing yog ib txoj kev siv electrochemical los ntawm qab mus rau saum toj. Nws xaiv cov qhov siab tshaj plaws ntawm qhov roughness ntawm qhov chaw, ua kom cov micro-profile sib npaug thiab tshem tawm ib txheej nyias ntawm cov khoom. Nws feem ntau ua rau Ra siab dua li kev txhuam zoo tab sis muab cov txiaj ntsig zoo dua xws li kev tiv thaiv corrosion thiab kev ntxuav tau zoo.
Rooj Sib Piv Ncaj Qha
| Feature | Kev Txhuam Txhuam | Kev siv hluav taws xob
|
| Txheej Txheem | Kev txhuam lub cev siv cov khoom siv uas nyias dua (ntawv xuab zeb, log txhuam). | Kev yaj ntawm cov tshuaj electrochemical hauv cov dej da dej acid (piv txwv li, phosphoric/sulfuric acid). |
| Lub Hom Phiaj Tseem Ceeb | Ua tiav qhov tshwj xeeb aesthetic thiab qis Ra tus nqi (smoothness). | Txhim kho cov khoom ua haujlwm: kev tiv thaiv corrosion, deburring, kev ntxuav tau.
|
| Kev Tshem Tawm Khoom Siv | Xaiv tau, tuaj yeem smear thiab deform lub txheej nto. | Sib xws, tshem tawm cov khoom siv ntawm tag nrho qhov chaw uas raug nthuav tawm, nrog rau qhov nyiam kom muaj cov ncov dua li cov hav.
|
| Kev Ncaj Ncees Ntawm Qhov Chaw | Yuav tawm cov khoom me me uas lo rau hauv, txheej hlau "ua haujlwm", cov pob me me tawg, thiab cov kev ntxhov siab tensile seem. | Tsim ib qho chaw huv si, tsis muaj kuab paug nrog ib txheej oxide passive (rau cov hlau tsis xeb).
|
| Kev Tiv Thaiv Kev Xeb | Nruab nrab. Qhov chaw du tuaj yeem ua rau qeeb qeeb thawj zaug tawm tsam, tab sis cov kuab paug uas nkag mus rau hauv thiab cov txheej txheem deformed tsim cov chaw pib. | Zoo heev. Tshem tawm cov txheej tsis muaj zog thiab tsim cov txheej txheem ruaj khov, sib xws.
|
| Kev Huv Si thiab Kev Ua Kom Huv Si | Zoo. Ib qho chaw du thiab yooj yim ntxuav, tab sis cov kab me me tuaj yeem ua rau muaj cov kab mob thiab cov kuab paug. | Zoo kawg nkaus. Tsim tau ib qho chaw du thiab tsis lo, thiab tsis muaj qhov tawg uas yooj yim rau kev tua kab mob. Zoo tagnrho rau kev lag luam tshuaj, khoom noj thiab dej haus, thiab kev lag luam semiconductor. |
| Geometric Peev Xwm | Zoo heev rau cov qauv yooj yim sab nraud. Nyuaj lossis tsis yooj yim rau cov kev hla sab hauv nyuaj, cov qhov me me, lossis cov raj ntev. | Zoo heev rau cov qauv yooj yim sab nraud. Nyuaj lossis tsis yooj yim rau cov kev hla sab hauv nyuaj, cov qhov me me, lossis cov raj ntev. |
| Qhov tshwm sim Ra (Ib txwm muaj) | Muaj peev xwm ua tiav Ra qis heev (< 0.25 µm / 10 µin) nrog kev siv zog txaus. | Feem ntau ua rau muaj Ra siab dua li cov txhuam zoo (piv txwv li, 0.4-0.8 µm / 16-32 µin), tab sis muaj kev ua tau zoo dua.

Xaiv Kev Txhuam Txhuam Thaum:
· Qhov yuav tsum tau ua tseem ceeb yog qhov zoo nkauj thiab daim iav tiav.
Tus nqi Ra qis heev yog qhov yuav tsum tau ua, raws li qhov yuav tsum tau ua.
· Cov khoom no yog ua los ntawm cov khoom siv uas tsis yog stainless hlau uas cov txheej passive tsis yog qhov txhawj xeeb.
· Tus nqi yog tus tsav tsheb loj, thiab cov txiaj ntsig ua haujlwm ntawm electropolishing tsis tas yuav tsum muaj.
Xaiv Electropolishing thaum:
· Kev tiv thaiv xeb yog qhov tseem ceeb tshaj plaws (piv txwv li, chaw nyob hauv dej hiav txwv, tshuaj lom neeg, lossis chaw kho mob).
· Yuav tsum tau ua kom huv si thiab ua kom tsis muaj kab mob ntau heev (piv txwv li, tshuaj, kev ua cov khoom siv bio-processing, cov khoom siv ua zaub mov).
· Koj yuav tsum tau txhuam cov duab geometries lossis cov nto sab hauv.
· Koj yuav tsum tshem tawm ib txheej uas raug kev ua haujlwm kom ua tau zoo dua (piv txwv li, hauv cov khoom siv hauv dav hlau).
· Koj yuav tsum xyuas kom meej tias muaj kev tshem tawm me me thiab txhim kho lub neej qaug zog.
Yog li ntawd, kev teev qhov tiav raws li tus nqi Ra xwb yog qhov yuam kev. Qhov kev xaiv yuav tsum tau tsav los ntawm kev ua haujlwm ntawm qhov. Rau ib daim duab puab zoo nkauj, kev txhuam hniav yog qhov zoo meej. Rau ib qho khoom tseem ceeb hauv lub twj tso kua mis lossis lub tshuab hluav taws xob, electropolishing yuav luag txhua lub sijhawm yog qhov kev xaiv zoo tshaj plaws hauv kev tsim kho.
