Yuav ua li cas electroplilding txhim kho cov nag tsis kam ntawm cov khoom? Cov txheej txheem dab tsi tuaj yeem txhim kho los nag?

Cov qauv hluav taws xob yog cov txheej txheem tso nyiaj ntawm cov hlau lossis alloy mus rau hauv cov khoom siv hluav taws xob los txhim kho cov khoom lag luam hluav taws xob, kev tiv thaiv corrosion, thiab lwm yam khoom. Txhim kho cov khoom muag los ntawm cov khoom ua tiav los ntawm kev xaiv cov khoom siv txheej xim tsim nyog, thiab sib txuas ua ke nrog lwm cov kev kho kom sib txawv ntawm cov txheej txheem. Cov hauv qab no yog cov ncauj lus kom ntxaws:

1. Xaiv rau cov khoom siv txheej zoo

Kev xaiv ntawm cov khoom electroplating yog qhov tseem ceeb los txhim kho los nag. Nag kuj feem ntau feem ntau corrosion tsis kam thiab cov khoom siv dej, yog li cov khoom siv txheej ua kom zoo thiab cov khoom lag luam zoo siab thiab cov khoom lag luam zoo. Cov hauv qab no yog qee cov khoom siv txheej thiab lawv cov yam ntxwv:

{{0- zinc txheej: zinc coicting) muaj cov galvanizing zoo tshaj, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig huab cua zoo. Zinc ua cov yeeb yaj kiab dense nyob rau hauv lub xub ntiag ntawm cov huab cua, ua kom muaj kev nkag mus rau cov dej noo thiab cov pa oxygen, li kev txhim kho cov khoom tiv nag.

{{0-} Cov txheej tsib xee npe: Nickel Txheej: Nickel Txheej Muaj muaj cov corrosion zoo tshaj plaws thiab hnav tsis kam. Nickel plating tuaj yeem siv tau nyob ib leeg lossis ua txheej txheej rau lwm cov khaub noom (xws li chrome plating) kom txhawb ntxiv los nag nag.

- chromium plating muaj kev tiv thaiv zoo thiab corrosion tsis kam, ua rau muaj cov kua qaub thiab qab ntsev ntawm dej nag. Chromium plating feem ntau siv nyob rau ntawm cov khoom raug rau kev ncua rau kev ncua ntev, xws li cov khoom lag luam thiab kho vajtse.

{{0- hyper plating: tooj plating muaj cov kev coj ua zoo thiab corrosion tsis kam thiab siv nyob rau hauv electroplating ntawm cov khoom hluav taws xob. Tooj liab plating tuaj yeem pab ua txheej txheej, sib xyaw nrog lwm cov txheej plating, kom txhim kho tag nrho cov nag los nag.

- Alloy Plating: Alloy plating (such as zinc-nickel and zinc-iron alloys) combines the advantages of multiple metals, offering enhanced corrosion and rain resistance. Piv txwv li, zinc {{4-}}}} alloy alloy ua kom pom tau zoo heev corrosion corrosion lossis yog qhov siab- av noo.

2. Txhim kho cov txheej txheem electrandating txheej txheem

Txhim kho cov txheej txheem electrandating elecameters yog qhov tseem ceeb rau kev txhim kho cov khoom zoo thiab los nag ntawm cov txheej. Cov hauv qab no yog qee cov txheej txheem tseem ceeb thiab lawv txoj kev ua kom zoo:

- ntom ntom tam sim no: tam sim no ceev ncaj qha cuam tshuam cov tuab thiab ntom ntawm txheej. Ua kom muaj qhov ceev ceev tam sim no tuaj yeem nce cov tuab ntawm txheej, yog li txhim kho nag tsis kam. Txawm li cas los xij, kev ua kom sov ntau dhau tuaj yeem ua rau muaj kev sib tw lossis porosity nyob rau hauv txheej, uas nyob rau hauv lem txo corrosion tsis kam. Yog li ntawd, nws yog ib qho tseem ceeb kom xaiv qhov ceev tam sim no thaum ua kom zoo dua qub.

{{0- Lub sijhawm plating: plating lub sijhawm txiav txim siab txheej tuab. Lub sijhawm npaj plating ntev dua tuaj yeem nce cov txheej txheej tuab, tab sis kuj nce nqi ntau lawm. Yog li ntawd, lub sijhawm npaj siab tawv plating yuav tsum tau txiav txim siab raws li cov khoom lag luam npaj thiab kev ua tau zoo.

-} electrolyte composition: cov electrolyte sib zog cuam tshuam zoo thiab ua tau zoo ntawm txheej. Los ntawm kho cov electrolyte ntxiv, pH, thiab kub thiab kev sib txuam ntawm cov txheej tuaj yeem hloov kho, yog li txhim kho nag tsis kam. Piv txwv li, ntxiv rau brightener tuaj yeem txhim kho txoj kev ua kom zoo nkauj thiab corrosion tsis kam ntawm txheej.

- Pretreatment: Cov txheej txheem ua ntej ua ntej cov electropling (xws li ua kom muaj zog, thiab ua kom muaj zog ntxiv rau cov nplaum thiab qhov zoo ntawm txheej. Zoo pretreatment tshem tawm impurities thiab oxide txheej los ntawm cov workpiece nto, kom ntseeg tau qhov zoo ntawm cov txheej thiab substrate, li kev txhim kho los nag tsis kam.

3. Yuav ua li cas lwm yam kev kho mob saum npoo av

Ntxiv rau cov elecoplating, lwm yam kev kho mob saum npoo tuaj yeem ua ke los txuas ntxiv txhawb cov khoom los nag. Cov hauv qab no yog qee qhov siv thev naus laus zis feem ntau:

- Passivation: Passivation yog kev siv tshuaj lom neeg ua rau cov txheej txheem xim av tom qab tsim cov txheej txheem sib xyaw ua ke. Piv txwv li, passivation tuaj yeem txhim kho cov ntsev kom huv ntawm cov zinc tsho loj.

{{0- txheej: Thov cov txheej txheem organic (xws li cov xim av lossis hmoov txheej) rau cov khoom lag luam hluav taws xob ntxiv thiab corrosion tsis kam. Txheej tsis tsuas yog muab ib txheej ntxiv ntawm kev tiv thaiv tab sis kuj txhim kho cov khoom zoo nkauj.

- anodizing: rau txhuas thiab aluminium thiab anoldizing ua ib qho tuab txhuas oxide zaj duab xis nrog zoo heev corrosion thiab nag. Lub hws ntawm anodized zaj duab xis tseem tuaj yeem raug muab tso rau ntxiv txhim kho nws cov dej tsis kam.

-} Electroless plating Plating yog ib qho txheej txheem plating uas tsis tas yuav tsum tau siv cov khoom siv hluav taws xob tam sim no thiab tuaj yeem tsim cov txheej txheem sib dhos. Electroless npib - phosphorus alloy plating muab, ua rau nws tsim nyog txhim kho cov khoom los nag.

4. Kev ceev faj hauv cov ntawv thov siv

Hauv kev tsim khoom tiag tiag, txhawm rau txhim kho cov khoom muag los nag, cov ntsiab lus hauv qab no yuav tsum tau txiav txim siab:

{-} Endment} Endment} Endment} Cov ntaub ntawv tsim nyog rau cov khoom siv thiab cov txheej txheem raws li cov khoom lag luam ua haujlwm. Piv txwv li, hauv cov khoom lag luam marine, cov plating cov khoom nrog cov ntsev ntau corrosion corrosion siab (xws li zinc-}}}} Alloy plating) yuav tsum tau xaiv.

- Kev Tswj Xyuas Zoo: nruj tswj hwm txhua kauj ruam ntawm cov txheej txheem hluav taws xob kom ntseeg tau tias cov txheej txheem tuab, kev sib dhos, thiab cov nplaum ua kom tau raws li qhov xav tau. Tsis tu ncua kev coj ua ntsev kom tsis tu ncua ntsev thiab corrosion tsis kam ntsuas kom ntseeg tau tias cov khoom los nag tsis tuaj yeem tiv thaiv.

- Tus nqi tswj: Txhim kho cov txheej txheem ua kom zoo dua thiab txo cov nqi ntau lawm thaum ua kom muaj kev ua haujlwm. Piv txwv li, los ntawm kev xaiv cov khoom plating cov ntaub ntawv thiab thicknesses, khoom nkim thiab kev siv hluav taws xob tuaj yeem txo.
