Polishing yog ib txoj hauv kev ua haujlwm uas siv cov khoom siv kho tshuab, tshuaj, lossis electrochemical ua kom txo tau qhov roughness ntawm lub workpiece, yog li ua tiav qhov ci thiab du nto. Cov txheej txheem polishing feem ntau yog ua haujlwm nyob rau hauv precision machinery thiab optical industries. Polished workpieces feature du nto uas nthuav tawm cov khoom zoo heev.Electrolytic polishingthiab tshuaj polishing yog siv dav hauv kev ua haujlwm siab -kawg stainless hlau tubing; kab lus no yuav qhia qhov txawv ntawm ob txoj kev polishing no.
Electropolishing yog dab tsi?
Electrolytic polishing-tseem hu ua electrochemical polishing- yog cov txheej txheem ua haujlwm uas cov khoom ua haujlwm tau muab tso rau hauv cov khoom siv hluav taws xob los txhim kho qhov smoothness ntawm cov hlau thiab ua kom lub ntsej muag ci ntsa iab. Yuav luag txhua cov hlau tuaj yeem ua rau electrolytic polishing, xws li stainless hlau, carbon hlau, titanium, aluminium alloys, tooj liab alloys, thiab npib tsib xee alloys; Txawm li cas los xij, nws daim ntawv thov yog dav siv nrog stainless hlau. Los ntawm kev sib xyaw ua ke ntawm cov hluav taws xob tam sim no ntws ntawm cov anode thiab cathode, nrog rau cov tshuaj electrolytic polishing, micro-geometry ntawm cov hlau saum npoo yog ua kom zoo dua qub, thiab nws qhov roughness ntawm qhov saum npoo yog txo, yog li ua tiav lub hom phiaj ntawm qhov ci, du workpiece nto.
Qhov zoo thiab qhov tsis zoo ntawm Electropolishing
I. Qhov zoo:
- Exceptional Surface Quality: Qhov saum npoo ua tiav daim iav - qib tiav (Ra Tsawg dua lossis sib npaug li 0.25 μm), tsis muaj khawb thiab cov txheej txheem kev ntxhov siab uas nyob ib puag ncig sab laug los ntawm kev siv tshuab polishing. Nws tiv taus qhov adhesion ntawm impurities, ua kom muaj kev huv huv siab heev- ua rau nws zoo tagnrho rau cov ntawv thov kev nyiam huv huv, xws li hauv kev lag luam tshuaj thiab zaub mov.
- Txhim kho Corrosion Resistance: Cov txheej txheem electrolytic tshem tawm cov impurities saum npoo thiab ua kom muaj cov denser, chromium- nplua nuj passivation zaj duab xis. Piv nrog rau cov qauv stainless hlau tubing, qhov no ua kom muaj zog tiv thaiv xeb thiab oxidation, uas ua rau lub neej ua haujlwm ntev dua.
- Tsis tshua muaj dej tsis kam: Lub sab hauv du ua kom tsis muaj zog thaum lub sij hawm xa cov kua los yog roj, yog li txo qis kev siv zog. Tsis tas li ntawd, nws txo qhov kev pheej hmoo ntawm kev scaling thiab clogging, ua rau nws tshwj xeeb tshaj yog zoo - haum rau kev thauj mus los ntawm siab - purity gases thiab precision kua.
II. Qhov tsis zoo:
- Cov Nqi Ntau Lawm: Cov txheej txheem electropolishing yog qhov nyuaj- yuav tsum tau ua ntej- kho, kub- tswj electrolysis, thiab tom qab- kho- thiab suav nrog cov nqi siab rau cov khoom siv thiab electrolytes. Yog li ntawd, tus nqi ntawm electropolished tubing yog 30% mus rau 50% siab tshaj tus qauv stainless hlau tubing los yog mechanically polished tubing.
- Kev txwv tsis pub ua: Cov txheej txheem tsim cov kev cai tshwj xeeb ntawm cov raj dej tshwj xeeb; cov raj uas nyias nyias, ntev ntev, los yog tsis sib xws yog qhov nyuaj rau electropolish uniformly, uas tuaj yeem ua rau qhov tsis sib xws ntawm gloss. Tsis tas li ntawd, cov txheej txheem tsis tuaj yeem kho qhov deformations loj lossis qhov tsis xws luag hauv lub raj nws tus kheej.
- Electrolyte Disposal Requirements: Cov kua qaub los yog alkaline electrolytes siv thaum lub sij hawm electropolishing yog cais raws li cov pov tseg txaus ntshai. Lawv xav tau kev kho tshwj xeeb ua ntej tso tawm; Kev pov tseg tsis raug tuaj yeem ua rau muaj kuab paug ib puag ncig, yog li ua rau lub tuam txhab kev ua raws li ib puag ncig tus nqi thiab kev tswj hwm.
Chemical Polishing yog dab tsi?
Chemical polishing yog txheej txheem uas cov microscopic protrusions ntawm cov khoom nto yaj nyiam tshaj qhov chaw so thaum muab tso rau hauv cov tshuaj nruab nrab, yog li yielding ib tug du nto.
Lub ntsiab zoo ntawm txoj kev no yog tias nws yuav tsum tsis muaj cov cuab yeej nyuaj, tuaj yeem siv rau cov khoom siv nrog cov duab sib txawv, thiab tso cai rau kev sib txhuam ntawm ntau lub workpieces, uas ua rau muaj kev ua haujlwm siab.
Qhov tseem ceeb ntawm cov tshuaj polishing yog nyob rau hauv kev tsim cov tshuaj polishing. Qhov saum npoo roughness feem ntau ua tiav los ntawm cov tshuaj polishing yog nyob ntawm qhov kev txiav txim ntawm kaum ntawm micrometers.
Qhov zoo thiab qhov tsis zoo ntawm tshuaj lom neeg polishing
- Qhov zoo yog nyob rau hauv qhov yooj yim ntawm cov khoom siv tshuaj polishing thiab nws lub peev xwm los ua cov txheej txheem nrog cov geometry nyuaj.
- Qhov tsis zoo muaj xws li polishing zoo tsis zoo rau ntawm electrolytic polishing; Tsis tas li ntawd, cov tshuaj polishing siv tau siv lub neej luv luv, thiab nws cov kev hloov kho thiab kev tsim dua tshiab yog qhov nyuaj. Tsis tas li ntawd, thaum lub sij hawm siv tshuaj polishing txheej txheem, nitric acid emissions ntau yam tshuaj lom daj - cov pa taws xim av, ua rau muaj kuab paug ib puag ncig hnyav.
Dab tsi yog qhov txawv ntawm electrolytic polishing thiab tshuaj polishing?
| Hom txheej txheem | Qhov zoo | Qhov tsis zoo | Tej kev siv |
| Electropolishing | High Deg tiav, Deburring | Cov cuab yeej siv yooj yim, kev siv hluav taws xob siab | Kev kho mob, Khoom noj khoom haus, Aviation |
| Tshuaj Polishing | Haum rau cov duab complex | Sensitive rau parameters; kev sib xws yog qhov nyuaj rau kev tswj | Cov Txheej Txheem Txheej Txheem, Ua ntej- kho |
I. Electropolishing
Muab cov txiaj ntsig polishing zoo tshaj plaws, muaj peev xwm ua tiav daim iav - qib tiav (qhov roughness tuaj yeem ncav cuag Ra Tsawg dua lossis sib npaug li 0.1 μm). Tsis tas li ntawd, ib zaj duab xis passivation ua rau ntawm cov hlau nto tom qab polishing, ho txhim kho corrosion kuj.
Electropolishing muaj ntau yam kev siv thiab tuaj yeem siv rau ntau yam hlau thiab alloys -xws li stainless hlau, tooj liab, txhuas, thiab npib tsib xee- ua kom nws tshwj xeeb tshaj yog haum rau cov khoom uas muaj cov geometries nyuaj thiab siab precision (xws li cov cuab yeej kho mob thiab cov cuab yeej ntsuas precision). Txawm li cas los xij, cov txheej txheem ua rau qhov poob me ntsis ntawm qhov (txawm tias cov khoom tshem tawm yog tswj tau).
II. Tshuaj Polishing
Cov nyhuv polishing yog me ntsis qis dua li ntawm electropolishing; nto roughness feem ntau ntog hauv thaj tsam ntawm Ra 0.2-0.8 μm. Tsis muaj qhov sib txawv passivation zaj duab xis yog tsim, uas ua rau tsuas yog txhim kho kev txhim kho corrosion.
Tshuaj polishing yog zoo- haum rau batch ua ntawm hlau qhov chaw nrog geometries yooj yim (xws li kho vajtse fittings thiab txhuas profiles), muab cov nqi qis dua thiab ua tau zoo dua. Txawm li cas los xij, nws nthuav tawm tsis zoo polishing uniformity ntawm qhov chaw nrog cov duab nyuaj, ua rau lawv muaj kev cuam tshuam rau hauv cheeb tsam corrosion lossis tsis sib xws polishing.
xaus
Hauv cov ntsiab lus, electropolishing yog tsim rau cov ntawv thov uas xav tau siab precision, superior nto tiav, thiab muaj zog corrosion kuj; thaum nws suav cov nqi siab dua, nws siv rau cov khoom siv hlau xws li stainless hlau, txhuas, thiab tooj liab. Chemical polishing, conversely, yuav tsum tsis muaj cov cuab yeej complex, yooj yim rau kev ua, thiab muaj kev ua haujlwm siab, ua rau nws tsim nyog rau qhov chaw nrog cov geometries nyuaj thiab cov kev xav tau me ntsis txog qhov roughness. Hauv kev siv cov tswv yim, txoj kev polishing tsim nyog yuav tsum raug xaiv raws li cov khoom siv, cov kev xav tau zoo, thiab kev txwv nyiaj txiag.
