Qhov sib txawv tseem ceeb ntawm electroplating thiab galvanisation yog cov txheej txheem electroplating tuaj yeem siv los siv cov hlau tsim nyog rau ntawm ib qho khoom thaum galvanization yog siv los siv cov zinc txheej nyias ntawm cov hlau.
Electroplating yog hom galvanization. Electroplating tuaj yeem siv rau kev siv cov hlau sib txawv ntawm qhov chaw xws li kub, nyiaj, chromium, rhodium, tooj liab, thiab lwm yam. Txawm li cas los xij, galvanization feem ntau tsom rau kev siv cov zinc molten rau ntawm cov hlau xws li steel..
Electroplating yog dab tsi?
Electroplating yog txheej txheem tshuaj xyuas uas ib lub hlau yog coated rau lwm cov hlau siv hluav taws xob. Cov txheej txheem no suav nrog lub xov tooj ntawm tes electrochemical uas muaj ob lub electrodes uas yog raus rau hauv tib lub electrolyte. Txawm li cas los xij, peb yuav tsum siv cov khoom ua tus cathode. Lub anode yog cov hlau uas peb yuav siv rau ntawm cathode lossis inert electrode.
Nyob rau hauv cov txheej txheem ntawm electroplating, lub kaw lus yog thawj zaug muab hluav taws xob tam sim no los ntawm sab nraud, uas ua rau cov electrons hauv electrolyte dhau los ntawm anode mus rau cathode. Lub cathode muaj tshem tau electrons. Hauv cov tshuaj electrolytic, muaj cov hlau ions uas tuaj yeem txais cov khoom siv hluav taws xob. Tom qab ntawd, cov hlau ions raug txo qis thiab ua hlau atoms. Tom qab ntawd cov hlau atoms tuaj yeem tso rau ntawm qhov chaw ntawm cathode. Thiab, tag nrho cov txheej txheem no hu ua "plating".

Txawm li cas los xij, peb yuav tsum ua tib zoo xaiv cov electrolyte. Yog tias cov electrolyte muaj lwm cov hlau ions uas tuaj yeem tso nrog rau qhov xav tau hlau ion, plating yuav tsis raug. Yog li ntawd, lub cathode uas cov hlau yog plated yuav tsum huv si thiab tsis muaj kab mob. Txwv tsis pub, lub plating ua tsis ncaj. Cov kev siv loj ntawm cov txheej txheem electroplating yog rau kev kho kom zoo nkauj lossis tiv thaiv corrosion.
Galvanization yog dab tsi?
Galvanisation yog ib qho kev tshuaj ntsuam xyuas uas peb siv los ua ib txheej zinc nyias ntawm lub substrate. Feem ntau, cov khoom siv hlau yog siv los ua cov substrates, thiab peb tuaj yeem ua cov galvanization ntawm submerging cov khoom nyob rau hauv ib tug molten zinc da dej. Thaum lub sijhawm txheej txheem no, zinc hlau yog siv rau ntawm cov hlau los ua ib qho kev txi anode los tiv thaiv cov hlau los ntawm xeb. Hauv lwm lo lus, yog tias muaj khawb ntawm cov zinc txheej, cov hlau tseem tiv thaiv. Feem ntau, peb hu txoj kev no "kub-dip galvanisation" vim tias nws siv cov zinc da dej ntawm qhov kub thiab txias, thiab cov khoom yog dipped nyob rau hauv nws kom tau ib txheej hlau siv rau ntawm cov hlau.

Peb tuaj yeem nrhiav ntau hom txheej txheem galvanization nyob ntawm cov txheej txheem. Qee tus ntawm lawv suav nrog cov hauv qab no:
- Kub-dip galvanisation - nws suav nrog kev tso rau ntawm lub substrate hauv molten zinc
- Nruam galvanizing - qhov no yog ib daim ntawv ntawm kub-dip galvanisation, tab sis qhov no tsim ib txheej zinc nyias nyias; Yog li, qhov kev tiv thaiv corrosion yog sib piv tsawg dua
- Cov tshuaj tsuag cua sov - txoj kev no suav nrog kev txau ntawm cov zinc semi-molten rau hauv substrate
- Electroplating - ib txoj hauv kev uas siv cov khoom thiab zinc hlau ua electrodes hauv electrochemical cell
- Mechanical plating - qhov no yog ib txoj hauv kev tsis tshua muaj hluav taws xob uas tseem ceeb hauv kev tso lub tsho uas siv lub zog thiab cua sov
Qhov txawv ntawm Electroplating thiab Galvanization yog dab tsi?
Electroplating yog hom galvanization. Qhov sib txawv tseem ceeb ntawm electroplating thiab galvanisation yog cov txheej txheem electroplating tuaj yeem siv los siv cov hlau tsim nyog ntawm ib qho khoom thaum galvanisation yog siv los siv cov zinc txheej nyias ntawm cov hlau. Yog li, electroplating tuaj yeem siv cov hlau tsim nyog xws li zinc, tooj liab, rhodium, chromium, kub thiab nyiaj thaum galvanisation siv zinc hlau molten.
Hauv qab infographic qhia txog qhov sib txawv ntawm electroplating thiab galvanisation.
Summary – Electroplating vs Galvanisation
Electroplating thiab galvanisation yog qhov tseem ceeb rau ob qho tib si kho kom zoo nkauj thiab ua haujlwm. Electroplating yog ib hom galvanization. Qhov sib txawv tseem ceeb ntawm electroplating thiab galvanisation yog cov txheej txheem electroplating tuaj yeem siv los siv cov hlau tsim nyog ntawm ib qho khoom thaum galvanisation yog siv los siv cov zinc txheej nyias ntawm cov hlau.
