Q1: Lub hom phiaj tseem ceeb ntawm polishing txhuas, thiab dab tsi cov qauv uas muaj ntau?
A1:Txhuas polishing cov hom phiaj los txhim kho cov kev ua kom zoo nkauj saum npoo av, txhim kho corrosion tsis kam, thiab npaj cov hlau rau kev kho tom ntej (xws li anodizing lossis pleev xim). Cov qauv tseem ceeb muaj xws li:
NEEG KHO TSHUAB POLISHING: Siv cov cuab yeej abrasive (buffing log, Sandpaper) kom tshem tawm cov khawb thiab oxidation.
Tshuaj Lom Neeg cai Polishing: Siv cov kev daws teeb meem lossis cov kev daws teeb meem alkaline kom yaj txawv txawv (piv txwv li, nitric-phosphoric acid mixtures).
Kev Hluav Taws Xob: Electrochemical tshem tawm cov khoom saum npoo av hauv ib da dej kom ua tiav txoj kev du, ua tiav.
Vibratory Tinishing: Tumbling seem nrog abrasive xov xwm nyob rau hauv lub thawv vibrating rau uniform deburring thiab polishing.
Daim ntawv thov: Aerospace cov khoom sib xyaw ua ke zoo li turbine li yauv kho tshuab polishing los txo cov tshuab hluav taws xob siv hluav taws xob rau daim iav zoo li lub xov tooj cua ntse.
Q2: Yuav ua li cas rau cov neeg kho tshuab Polishing txawv txawv ntawm electropolishing nyob rau hauv cov nqe lus thiab cov txiaj ntsig tau?
A2:
| Yam | NEEG KHO TSHUAB POLISHING | Kev Hluav Taws Xob |
|---|---|---|
| Kev ua | Abrasive txhuam kwv yees ua manually los yog ntawm tshuab. | Electrolytic kev sib cais hauv ib lub cev roj av. |
| Nto tas | Matte rau ib nrab-gloss; Nyob ntawm abrasive grit. | Siab-ci, uniform tiav nrog ra<0.1 μm. |
| Cov Khoom Tawm Tshem Tawm | 5-20 μm txheej tshem tawm; kev pheej hmoo ntawm kev sib zog. | 10-50 μm tshem; meej, tswj thinning. |
| Tus nqi | Cov khoom siv tsawg; ua hauj lwm zoo. | High pib teeb tsa; txo qis cov nqi zog ntev. |
| Cov Ntawv Thov | Automotive trim, vajtse vaj tse. | Cov cuab yeej kho mob, cov khoom siv ua khoom noj. |
Tus yam ntxwv: Tus neeg saib xyuas Swiss siv cov neeg kho tshuab polishing rau cov txhuam hniav ua tiav rau cov neeg lom zem tab sis electropolishes sab hauv zog los txo kev sib txhuam.
Q3: Cov kev txwv thiab cov kev txwv ntawm kev ua polishing rau txhuas alloys?
A3:
Qhov Zoo:
Hov ceev: Ua tiav cov chaw du hauv 1-5 feeb (thiab cov sijhawm rau cov txheej txheem tshuab).
Ua nyuaj geometry: Uniformly polishes intricate cov duab (piv txwv li, cua sov so) tsis muaj kev siv zog.
Tsawg Tool: Yuav tsum muaj tsuas yog kua qaub-resistant tso tsheb hlau luam thiab cua sov.
Kev txwv:
Cov tshuaj lom los ntawm kev lom zem: Nitric acid-boofed cov ntsiab lus tso tawm memes, xav tau cua.
Alloy txwv tsis pub: High-tooj liab alloys (piv txwv li, 2024) yuav etch tsis ncaj ncees.
Porosity Deg: Dhau polishing tuaj yeem nthuav cov nplej muaj ciam, txo corrosion tsis kam.
Cov tswv yim Kev Pab Nkhaus:
Siv phosphoric-sulfuric acid blering kom muaj kev nyab xeeb dua, cov khoom qeeb qeeb.
Ntxiv inhibitors zoo li Triethanoline los tiv thaiv alloys tsis yooj yim.
Kev Kawm Txog: Ib qho chaw muag khoom German tau ua rau cov txheej txheem polishing los ntawm 70% los ntawm kev hloov mus rau tshuaj polishing rau txhuas tshuab nkhaus nkhaus.
Q4: Yuav ua li cas tuaj yeem siv cov txheej txheem hauv eco
A4:Kev ua kom muaj kev coj ua kom pom tseeb ntawm cov khib nyiab, lub zog, thiab cov tshuaj lom:
Ib yam qhuav neeg kho tshuab polishing: Pob zeb diamond-impregnated pads tshem tawm cov dej thiab slurry pov tseg.
Biodegradable media: Walnut Plhaub lossis Corncob Abrasives hauv Chubblers.
Acid-dawb Electropolishing: Sodium nitrate lossis citrate electrolytes hloov cov kev phom sij chromic acid.
Ubcling: Kaw-voj Pom rov qab thiab rov ua polishing slurtries.
Tus yam ntxwv: Asmeskas cov chaw tsim khoom ntawm lub vaj huam sib luag ci ntsa iab ntab tau txais qhuav polishing, txiav cov dej khib nyiab los ntawm 40%.
Q5: Dab tsi cov kev tswj kom zoo ua kom pom tseeb raws li cov txiaj ntsig hauv txhuas polishing?
A5:
Nto Roughness Ntsuas: Portable profilomometers ntsuas RA (arithmetic roughness) los xyuas kev ua raws li (piv txwv li ra tsawg dua lossis sib npaug}. 4 μm rau kev kho kho kho kho kab).
Kev Saib Xyuas Kev Pom: UV teeb lossis nthuav tawm cov qauv micro-khawb lossis pitting.
Kev tshuaj nplaum nplaum: Cov kev ntsuam xyuas daug ntov ua kom cov chaw ua haujlwm polished tau sib xws nrog cov txheej txheej.
Corrosion Kuj: Kev ntsuas ntsev (ASTM B117) siv tau qhov kev ua tau zoo hauv cov chaw hnyav.
Tus qauv:
ISO 21994: Qhia meej polishing torances rau automotive aluminium.
ASTM E766: Kev ntsuas hluav taws xob cov txheej txheem rau kev ntsuas saum npoo sib dhos.
Kev Kawm Txog: Lub chaw tsim khoom siv dav hlau siv hluav taws xob lub zeem muag los soj ntsuam cov kab tis zoo nkauj, txo tus nqi los ntawm 25%.
