Chrome Plating Aluminium Alloy Tuag Casting

Khoom Paub meej

Chrome-plated siab aluminium alloy tuag-casting yog aluminium alloy tuag-casting nrog chromium-plated nto kho. Tuag-casting yog hydraulically txhaj molten hlau rau hauv cov xuab zeb pwm los yog pwm kab noj hniav, txias nws thiab tsim nws. Tom qab lub pwm qhib, qhov chaw ntawm ntau yam duab tuaj yeem tau txais. Nws yog siv nyob rau hauv kev lag luam thiab tuaj yeem tuag-cam khwb cia txhuas, zinc, tooj liab, magnesium alloys, thiab lwm yam. Chrome plating yog cov txheej txheem kho deg. Electroplating ib txheej ntawm chromium rau saum npoo ntawm aluminium alloy tuaj yeem ua rau saum npoo ntawm aluminium alloy tuag castings smoother thiab txhim kho nws cov kev ua tau zoo thiab zoo li.

Aluminium alloy chrome plating nto kho cov kauj ruam

Aluminium alloy chromium plating nto kev kho mob yog siv dav siv thev naus laus zis txhim kho uas feem ntau suav nrog ob kauj ruam tseem ceeb, xws li ntxuav thiab pickling. Ob kauj ruam no yuav piav qhia meej hauv qab no:

1. Kev ntxuav theem:

Kev ntxuav yog thawj kauj ruam hauv tag nrho cov txheej txheem kho saum npoo. Nws lub hom phiaj tseem ceeb yog txhawm rau tshem tawm cov av, impurities thiab oxides ntawm aluminium alloy nto kom ntseeg tau tias cov txheej txheem chrome plating tom ntej tuaj yeem ua tau zoo. Feem ntau, kev ntxuav tuaj yeem ua tau nyob rau hauv ob txoj hauv kev tseem ceeb, uas yog kev tu txhua yam thiab tshuaj ntxuav.

• Mechanical Cleaning: Kev tu tshuab siv lub cev muaj zog, xws li sandblasting lossis txhuam hniav, tshem tawm cov khoom, roj, thiab lub teeb oxide txheej los ntawm aluminium alloy nto. Qhov no pab muab qhov chaw ua haujlwm zoo dua rau kev tu tshuaj tom ntej.
• Kev tu tshuaj lom neeg: Tom qab kev tu txhua yam, kev tu tshuaj lom neeg feem ntau yuav tsum tau ntxiv kom tshem tawm cov oxides nyuaj thiab cov organic residues. Qhov no tuaj yeem ua tiav los ntawm soaking aluminium alloy qhov chaw hauv cov tshuaj ntxuav kom zoo. Cov txheej txheem tshwj xeeb ntawm kev ntxuav cov tshuaj thiab cov khoom siv ntawm cov tshuaj ntxuav yuav txawv nyob ntawm seb cov khoom raug kho thiab qhov yuav tsum tau ua.

2. Pickling theem:

Pickling yog ib qho ntawm cov kauj ruam tseem ceeb hauv kev kho saum npoo ntawm aluminium alloys. Nws muaj ob lub hom phiaj tseem ceeb: tshem tawm oxides thiab lwm yam impurities ntawm qhov chaw thiab tsim kom muaj qhov chaw haum rau chrome plating. Thaum lub sij hawm pickling txheej txheem, lub concentration thiab kub ntawm pickling tov yuav tsum tau precisely tswj kom paub meej cov kev ua tau zoo.

• Tshem tawm cov oxides: Pickling cov ntsiab lus feem ntau muaj cov kua qaub uas muaj zog, xws li sulfuric acid lossis hydrochloric acid, uas tuaj yeem yaj cov oxides sai sai rau ntawm qhov chaw ntawm aluminium alloy thiab tuaj yeem ua rau cov alkaline residues.
• Kev Npaj Nto: Cov txheej txheem pickling kuj pab txhim kho qhov zoo thiab roughness ntawm aluminium alloy nto kom zoo dua adhesion ntawm chromium plating. Cov kauj ruam no tseem yuav pab ua kom lub zog saum npoo ntawm aluminium alloy, ua rau nws tau txais ntau dua rau chrome plating.

Hauv cov ntsiab lus, aluminium alloy chromium plating nto kho yog txheej txheem nyuaj, uas tu thiab pickling yog cov kauj ruam tseem ceeb. Ua ke, lawv xyuas kom meej tias cov khoom kawg muaj cov khoom zoo chromium plating nrog superior corrosion kuj thiab cov khoom zoo nkauj. Yog li ntawd, kev tswj hwm nruj ntawm qhov tsis muaj thiab cov txheej txheem ntawm cov kauj ruam no yog qhov tseem ceeb kom ua tiav cov txiaj ntsig kev kho mob zoo ib yam.

Qhov zoo ntawm aluminium alloy chromium plating

1. Txhim khu kev tiv thaiv corrosion: Chromium plating tuaj yeem tsim cov txheej txheem tiv thaiv corrosion-resistant rau saum npoo ntawm aluminium alloys kom zoo tiv thaiv oxidation thiab corrosion, yog li prolonging lub neej kev pab cuam ntawm txhuas alloy qhov chaw, tshwj xeeb tshaj yog nyob rau hauv ntub los yog corrosive ib puag ncig.
2. Txhim kho hardness: Qhov sib ntxiv ntawm chromium tuaj yeem tsim cov theem ntxiv, xws li Al-Cr theem, uas tuaj yeem cuam tshuam cov qoob loo ciam teb thiab kev txav mus los, yog li txhim kho hardness thiab lub zog ntawm aluminium alloys. Qhov no ua rau cov khoom kho aluminium alloy tiv taus ntau yam kev ntxhov siab thiab hnav.
3. Txhim khu kev zoo nkauj: Cov chrome txheej tsis tsuas yog muab kev tiv thaiv corrosion, tab sis kuj ua rau kom cov gloss thiab zoo li ntawm aluminium alloy nto. Qhov no ua rau aluminium alloy qhov chaw zoo nkauj dua thiab ntxim nyiam, haum rau cov ntawv thov nrog cov kev xav tau zoo nkauj.
4. Txhim kho hluav taws xob conductivity: chrome-plated txheej ua raws li cov txheej txheem tiv thaiv kom zoo tiv thaiv oxidation ntawm aluminium alloy nto, yog li tswj nws cov hluav taws xob conductivity. Qhov no yog ib qho tseem ceeb rau cov ntawv thov uas xav tau cov khoom siv hluav taws xob zoo, xws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob.

Aluminium alloy chromium plating tuaj yeem tsis tsuas yog txhim kho lub cev ntawm cov khoom, xws li hardness thiab corrosion kuj, tab sis kuj txhim kho nws cov kev zoo nkauj thiab hluav taws xob conductivity, yog li nws muaj ntau yam kev siv hauv ntau lub teb. Ntawm Mindwell, peb muaj kev nplua nuj ntawm aluminium casting Surface kev kho mob, thiab peb muaj peb tus kheej kev koom tes kho deg Hoobkas, uas tuaj yeem muab rau koj nrog txhua qhov chaw kho aluminium alloy qhov chaw xws li chrome-plated aluminium die-casting qhov koj xav tau. Yog tias koj muaj kev xav tau customization, thov hu rau peb ncaj qha.
