Xaiv cov txheej txheem electroplilating lub sijhawm thiab nws cuam tshuam
Electroplating yog txheej txheem uas tsim cov hlau lossis alloy txheej ntawm ib substrate los ntawm kev tso nyiaj electrolytic. Kev xaiv ntawm electroplating cov txheej txheem lub sijhawm yog qhov tseem ceeb cuam tshuam rau cov txheej txheem zoo, tuab, kev sib xyaw, thiab ntau lawm kev ua haujlwm. Lub sijhawm sib txawv Electroplating lub sij hawm tuaj yeem cuam tshuam rau txheej txheej kev ua tau zoo, tsos cov nqi, thiab kev ua cov nqi. Kab lus no yuav tham txog cov qauv rau kev xaiv cov txheej txheem electroplating electroplating kom ua kom zoo rau cov txheej txheem zoo.
I. CRITERIA rau kev xaiv cov txheej txheem elevelplating lub sijhawm
1. Txheej tuab tuab yuav tsum
Lub sijhawm electroplating ncaj qha cuam tshuam rau txheej txheej txheej tuab. Feem ntau, ntev cov sij hawm electroplating ua rau cov txheej txheej tuab. Daim txheej thickness yuav tsum muaj kev sib txawv raws daim ntawv thov. Piv txwv li, kho kom zoo nkauj electroplating (xws li chrome thiab kub plating) tej zaum yuav tsum tau ua kom zoo dua qub, thaum muaj kev ua kom zoo dua qub, thaum muaj zog siv hluav taws xob, corrosion tsis kam, thiab lwm yam khoom. Yog li ntawd, xaiv ntawm electroplating lub sij hawm yuav tsum tau txiav txim feem ntau txiav txim siab raws li txheej txheej txheej tuab.
2. Tam sim no ceev
Thaum lub sij hawm lub tshuab hluav taws xob, ceev tam sim no (siv tam sim no ib qho chaw nyob) yog qhov tseem ceeb cuam tshuam rau txheej tuab. Rau lub sijhawm muab tso, qhov siab dua qhov ceev tam sim no, cov tuab tuab dua. Yog li ntawd, thaum xaiv lub sijhawm plating, qhov ceev tam sim no yuav tsum tau txiav txim siab. Cov mis rau kev xam lub sijhawm ua tiav yog:
\[
t =} \\ fac {h \\ lub sij hawm \\ rho \\ sij hawm} {i \\ sij hawm \\ thiab sij hawm}
\]
Qhov twg, \\ (t \\) yog lub sijhawm plating, \\ (\\ (\\) yog qhov kev siv hlau, thiab \\ (\\) yog qhov ua tau zoo tam sim no.
3. Plating daws cov tshuaj thiab cov kev xav tau
Qhov muaj pes tsawg leeg thiab kev nkag siab ntawm cov phiaj xwm kev sib cuam tshuam cuam tshuam rau kev tso nyiaj ntawm cov hlau ions. Piv txwv li, ib qho kev xav tau ntawm cov hlau ions hauv cov plating cov kev daws teeb meem hauv kev tso nyiaj sai dua thiab lub sijhawm luv luv. Tsis tas li ntawd, ntxiv rau hauv lub plating da dej (xws li breeders thiab leveling cov neeg sawv cev) kuj tseem yuav cuam tshuam tus nqi rho tawm thiab qhov zoo ntawm cov txheej. Yog li ntawd, cov plating da dej ua ke thiab cov kev xav yuav tsum tau txiav txim siab thaum xaiv lub sijhawm plating.
4. Substrate Cov Khoom
Cov khoom siv substrate, cov kev mob tshwm sim, thiab cov txheej txheem pretreatics cuam tshuam rau kev xaiv ntawm lub sijhawm plating. Piv txwv li, qhov chaw ntxhib yuav xav tau lub sijhawm teem sijhawm ib zaug kom ntseeg tau cov kev pab them ib leeg. Tsis tas li ntawd, qee cov sublots (xws li txhuas alloys thiab stainless hlau) xav tau tshwj xeeb plating) ua ntej plating, uas tuaj yeem cuam tshuam rau lub sijhawm plating.
5. Ntau Lawm Ua Tau Zoo thiab Tus Nqi
Lub sijhawm plating ncaj qha cuam tshuam cov kev ua tau zoo thiab cov nqi ua. Lub sijhawm npaj ua si nce ntxiv nce ntau lawm thiab txo cov peev txheej ntau lawm, thaum lub sijhawm luv dua yuav ua rau muaj cov txheej txheem tsis zoo. Yog li ntawd, thaum xaiv lub sijhawm plating, nws yog ib qho tseem ceeb kom txo lub sijhawm plating thaum ua kom tiav cov txheej txheem zoo los txhim kho kev ua tau zoo.
Ii. Cov nyhuv ntawm cov sijhawm sib txawv ntawm cov txheej
1. Txheej tuab tuab
Lub sijhawm plating yog qhov sib txuam zoo nrog txheej tuab. Sijhawm electroplating lub sij hawm tuaj yeem tsim cov txheej txheej tuab, tab sis lub sijhawm ntev ntev yuav ua rau muaj cov khoom siv tuab thiab ua kom sib dhos. Tsis tas li ntawd, cov txheej txheej tuab ntau dhau tuaj yeem tsim kev ntxhov siab sab hauv, ua rau tawg lossis ua rau muaj.
2. Txheej kev sib xyaw
Lub sijhawm luv luv luv luv hluav taws xob tuaj yeem ua rau cov txheej txheem tsis sib xws, tshwj xeeb tshaj yog nyob rau hauv workpieces, uas qhov tsis sib xws coating tuab yog ib qho. Lub sijhawm tsim nyog electroplating tsim nyog kom cov kev pab them tag nrho cov kev pab them, txhim kho cov khoom zoo thiab cov khoom lag luam.
3. Txheej zoo
Lub sij hawm luv luv luv luv hluav taws xob lub sij hawm tuaj yeem ua rau cov khoom tsis zoo, xws li xoob pleev, siab porosity, thiab cov khoom tsis zoo. Ntev lub sijhawm muaj peev xwm txhim kho cov txheej ntom ntom ntom thiab cov nplaum, tab sis ntev dhau lawm tuaj yeem ua rau cov kab ntxhib, cuam tshuam rau cov kab ntxwg thiab cov ntsej muag zoo.
4. Txheej Txheej
Kev cuam tshuam hluav taws xob cuam tshuam cov khoom siv hluav taws xob, xws li hnav tsis kam, corrosion tsis kam, thiab hluav taws xob cuam tshuam. Ntev ntev cov sij hawm muaj peev xwm txhim kho kev hnav thiab corrosion tsis kam ntawm cov txheej, tab sis ntau dhau lawm ntev ntev tuaj yeem ua rau cov txheej txheem sab hauv thiab txo nws cov khoom siv.
5. Ntau Lawm Ua Tau Zoo thiab Tus Nqi
Lub sijhawm electroplating cuam tshuam ncaj qha cuam tshuam kev ua haujlwm thiab cov nqi ua. Lub sijhawm dav dav ntxiv hluav taws xob nce kev siv hluav taws xob, cov nqi zog, thiab cov nqi sijhawm, txo kev ua haujlwm tau zoo. Yog li ntawd, thaum xaiv lub sijhawm electroplating, nws yog ib qho tseem ceeb kom txo lub sijhawm plating thaum ua kom tiav cov txiaj ntsig kev khwv nyiaj txiag.
III. Yuav ua li cas thiaj ua tau zoo electroplating lub sijhawm
1. Rationallyrally Tsim Electroplating Txheej Txheem Tsis
Lub sijhawm electroplating yuav tsum tau tsim hluav taws xob tsim raws li cov kev yuav tsum tau ua xws li txheej tuab tuab, thiab plating daws teeb meem. Lub sijhawm plating, txiav txim siab los ntawm kev sim thiab kev xam, tuaj yeem ua kom tau cov khoom siv tau zoo thaum txhim kho ntau lawm.
2. Txhim kho cov tshuaj elotlating daws cov tshuaj
Los ntawm kev kho cov lus sib xyaw thiab cov kev sib haum xeeb ntawm cov phiaj xwm kev plating, tus nqi rho tawm ntawm cov hlau ions tuaj yeem nce, lub sijhawm ua kom luv dua. Piv txwv li, ntxiv cov kev sib ntxiv uas tsim nyog tuaj yeem nce cov kev ua tau zoo tam sim no ntawm cov kev ua tiav plating thiab ua kom nrawm tus nqi xa tawm ntawm cov txheej.
3. Txhim kho substrate pretreatment
Los ntawm kev txhim kho substrate pretreatment cov txheej txheem (xws li ua kom zoo nkauj thiab kev plees ua kom zoo nkauj thiab cov nplaum muaj zog tuaj yeem txhim kho lub sijhawm electroplating. Piv txwv li, ua kom muaj zog ntawm txhuas alloy substrates tuaj yeem txhim kho tus nqi tau txais cov nqi pov tseg thiab qhov zoo ntawm cov txheej.
4. Siv cov cuab yeej siv tshuab
Kev rho tawm cov khoom siv hluav taws xob tso cai rau kev tswj lub sijhawm thiab lub sijhawm ntom ntom ntom ntom nti, txhim kho kev ruaj ntseg thiab muaj kev sib xws ntawm cov txheej txheem electroplating. Cov khoom siv rho tawm tuaj yeem txo cov neeg yuam kev, txhim kho ntau lawm, thiab txhim kho txheej txheem zoo.
5. Nquag tswj thiab saib xyuas cov plating daws
Tsis tu ncua tswj thiab saib cov muaj pes tsawg leeg thiab cov kev xav ntawm cov kev cog ntawm plating kom ntseeg tau tias nws qhov kev ruaj khov thiab xwm yeem. Kev laus thiab kev sib kis ntawm cov kev daws teeb meem tuaj yeem cuam tshuam tus nqi thauj khoom thiab qhov zoo ntawm cov txheej, yog li nws yuav tsum tau hloov lossis rov ua dua tshiab.
IV. Lub ntsiab
Kev xaiv ntawm cov txheej txheem hluav taws xob yog qhov cuam tshuam tseem ceeb uas cuam tshuam cov txheej txheem zoo, tuab, kev sib luag, thiab ntau lawm kev ua haujlwm. Thaum xaiv lub sijhawm plating, yam xws li cov txheej txheej nruj, cov khoom siv hluav taws xob uas yuav tsum tau ua, kev ua haujlwm tau zoo, thiab tus nqi yuav tsum tau txiav txim siab. Lub sijhawm sib txawv Electroplating lub sij hawm tseem ceeb cuam tshuam rau cov tuab tuab, kev sib dhos, zoo, thiab kev ua tau zoo ntawm txheej. Los ntawm kev tsim qauv tsim qauv hluav taws xob tsis ua tiav, txhim kho cov khoom siv ua kom zoo, thiab ua kom muaj zog ua kom tiav, txhim kho cov khoom siv ua kom zoo, txhim kho cov khoom siv ua kom zoo, thiab txhim kho kev ua haujlwm zoo.
