Yuav ua li cas Electroplating txhim kho cov dej noo tsis kam ntawm cov khoom? Dab tsi cov txheej txheem tuaj yeem txhim kho cov dej noo tsis kam?

Electroplating yog ib qho kev kho tshuab hauv cov khoom siv hluav taws xob dav hauv cov khoom siv hluav taws xob, tsheb, thiab lwm yam khoom lag luam tiv thaiv cov khoom, thiab kev ua kom zoo nkauj. Txawm li cas los xij, hauv qee cov ntawv thov, cov khoom xav tau siv ntev-}}}}}}}}}}}}}}}}}}}}}}}}}}}} moist environ environ use use in moist environ environ useນ siv hauv noo noo kev tshwj xeeb tshwj xeeb tshaj yog ib qho tseem ceeb. Txhim kho ya raws tsis tau tsuas yog nthuav tawm cov khoom lag luam lab tab sis kuj tseem txo cov kev ua tsis zoo thiab kev puas tsuaj los ntawm cov chaw noo noo. Cov kev sib tham hauv qab no yuav tshawb nrhiav seb cov khoom lag luam hluav taws xob tsis kam, tsom mus rau qhov ntsuas hluav taws xob tsis kam, thiab kev ua kom zoo dua qub, thiab ntsuas kev kho mob.

I. Xaiv cov txheej txheem electroplating

1. Xaiv cov hlau uas tsim nyog electroglating

Cov tsho hlau sib txawv muaj sib txawv noo noo noo noo. Piv txwv li, metrals xws li npib tsib xee, chromium, thiab zinc feem ntau siv nyob rau hauv electroplating vim lawv zoo heev corrosion thiab noo noo tsis kam.

-} Nickel plating, uas nws zoo tiv thaiv oxidation thiab corrosion ntawm substrate. Nickel plating tseem ua haujlwm ua ib txheej txheej, muab cov adhesion zoo rau cov txheej txheej plating txuas ntxiv.

{{0 {chromium plating muaj qhov ua yeeb yam txaus ntshai thiab corrosion oxide zaj duab xis uas muaj kev tiv thaiv zoo ntawm cov av noo thiab oxygen.

-} zinc plating: Zinc plating siv feem ntau siv los tiv thaiv cov hlau. Zinc ua cov yeeb yaj kiab dense dense hauv cov cheeb tsam noo, tiv thaiv cov substrate ntawm corrosion. Tsis tas li ntawd, Zinc plating tuaj yeem txhim kho ntxiv los ntawm passivation.

2. Multiilayer Electroplating Txheej Txheem

Thaum tib -}}}}}}}}}}}}}}}} ecent intrassed los txhim kho los ntawm cov nyhuv synergistic ntawm cov txheej txheem hlau sib txawv. Piv txwv li, cov txheej txheem multilayer electructoplating cov txheej txheem xws li nickel-}}}}}}}}}} {4 4} blocking kev nkag mus ntawm noo noo thiab corrosive tawm. Txhua txheej ua yeeb yam sib txawv, xws li muab cov nplaum, nruab nrab txheej txhim kho corrosion, thiab txheej txheej ua kom zoo nkauj thiab hnav tsis kam.

3. Alloy Electroplating Txheej Txheem

Alloy Electroplating muaj cov kev tso nyiaj ib txhij ntawm ob lossis ntau dua cov hlau ntawm cov saum npoo av los ua cov khoom siv tshwj xeeb. Piv txwv li, zinc {-}} {moist moist moist moist {{}} -} kav tiv thaiv. Tsis tas li ntawd, Nickel - phosphorus alloy txheej txheem thiab precision seem vim yog lawv lub siab ua haujlwm thiab noo noo tsis kam.

Ii. Nto Kho Kho Mob

1. Passivation

Passivation yog ib qho txheej txheem kho cov txheej txheem tom qab electroplating. Nws ua cov yeeb yaj kiab ntom nti oxide zaj duab xis nyob rau saum npoo ntawm txheej los ntxiv txhim kho nws noo noo tsis kam. Piv txwv li, passivation ntawm zinc co co oxide lossis chromate zaj duab xis nyob rau saum npoo, zoo tiv thaiv nws los ntawm noo noo thiab oxygen. Hla kev tsis tau tsuas yog txhim kho cov xeb ntawd ntawm cov txheej, tab sis kuj txhim kho nws cov tsos thiab coj tsis kam.

2. Kev sib khi

Sealing cuam tshuam nrog cov txheej txheej sib npaug nrog kev sib txuas tom qab electroplating txhawm rau sau cov micrropores hauv txheej, yog li kev txhim kho nws noo noo tsis kam. Cov tshuaj ntsuam sealing yog feem ntau cov organic los yog tsim zaj duab xis tiv thaiv nyob rau saum npoo ntawm plated txheej, ua rau nkag mus rau kev nkag ntawm ya raws thiab corrosive media. Kev sib khi yog tshwj xeeb rau haum rau cov pleev xim zoo xws li zinc thiab npib tsib xee.

3. Txheej

Ua ntawv thov cov txheej txheem tiv thaiv mus rau saum npoo ntawm cov txheej electropated tuaj yeem txhim kho ntxiv cov khoom lag luam noo noo. Piv txwv li, cov txheej txheem organic xws li epoxy cob, polyuretholarbon ua yeeb yaj kiab, lossis kev tiv thaiv fluorocarbon, kev tiv thaiv kev tiv thaiv zoo los ntawm kev ua haujlwm noo noo thiab corrosive. Cov txheej tsis tsuas yog ua kom ya raws cov khoom lag luam tab tom txhim kho cov khoom lag luam tiv thaiv thiab zoo nkauj.

III. Post {- kev ntsuas kev ntsuas

1. Kom qhuav

Tom qab Electropating, cov khoom yuav tsum tau muab kom huv si kom yooj yim noo noo thiab cov kuab tshuaj nyob rau ntawm ntug kev kom tiv thaiv corrosion hauv ib puag ncig corrosion. Lub ziab kub thiab lub sijhawm yuav tsum tau kom tsim nyog raws li cov khoom siv cov khoom thiab cov khoom lag luam cov khoom kom tsis txhob tawg lossis deformation ntawm txheej vim yog kub dhau.

2. Yo dej noo - e} pov thawj ntim

Rau cov khoom lag luam uas yuav tsum tau thauj khoom lossis khaws cia rau hauv cov dej noo noo, {}} eart packs ntim tuaj yeem siv los tiv thaiv cov khoom ntawm cov av noo. Noog noo - eC} Cov khoom lag luam ntim tsuas yog ncua cov khoom txee lub neej tab sis kuj tau txo cov av noo thiab kev puas tsuaj los ntawm cov av noo.

3. Kev tu ncua

Rau cov khoom lag luam siv hauv cov sij hawm noo, ib txwm saib xyuas thiab kev pabcuam yog kev ntsuas tseem ceeb los txhim kho lawv cov kev ya raws. Piv txwv li, kev ntxuav cov khoom lag luam kom tshem tawm cov av thiab cov khoom xeb thiab cov txheej txheem tiv thaiv kev tiv thaiv tuaj yeem ua kom zoo dua cov khoom lag luam lub neej.

IV. Lub ntsiab

Lub noo noo tsis kam ntawm cov khoom electroplated tuaj yeem xaiv cov txheej txheem kev kho kom haum, thiab siv cov ncej kho mob zoo, thiab siv cov ncej kho mob zoo. Hauv cov kev siv tswv yim, cov txheej txheem plating thiab cov kev kho kom haum raws li cov khoom lag luam kev ua haujlwm thiab kev ua haujlwm tau zoo rau kev ua kom zoo nkauj thiab noo noo tiv thaiv noo noo. Kev tu ncua thiab kev pabcuam tsis tu ncua kuj tseem ceeb ntsuas kom txuas ntxiv cov khoom lag luam lub neej. Los ntawm kev sib txuas cov thev naus laus zis thiab cov hau kev, noo noo tsis kam ntawm cov khoom electroplated tuaj yeem ua kom tau zoo ntawm ntau yam kev thov kev xaiv.
