Cov txheej txheem tsis rau electroplating ntawm hluav taws xob cua sov raj

Cov txheej txheem tsis rau electroplating ntawm hluav taws xob cua sov raj

1. Plating kub: 80 ± 5 degree

2. Ua hauj lwm load peev: 1-1.5dm ²/L

3. PH tus nqi: 9-10, kho nrog ammonia dej

4. Lub Sijhawm: Nyob ntawm qhov yuav tsum tau ua haujlwm, nws yuav tsum tsis pub tsawg tshaj 20 feeb.

4, Cov ntsiab lus tseem ceeb ntawm plating thiab kev saib xyuas ntawm cov tshuaj plating

1. Lub plating da dej yuav tsum tau ua los ntawm acid alkali resistant thiab high-temperature resistant ntaub ntawv, xws li polypropylene los yog fiberglass. Nws yog qhov zoo tshaj plaws los npog lub plating da dej kom txo tau cov cua sov thiab tiv thaiv kom tsis txhob poob rau hauv.

2. Thaum lub sij hawm plating txheej txheem, nws yog ib qho tsim nyog yuav tsum tau do ntau zaus, xws li mechanically lossis nrog cua.

3. Thaum lub sij hawm ua hauj lwm, cov kua tank yuav tsum tau circulated thiab lim ib teev ib zaug. Lub tshuab lim yuav tsum tau siv cov cuab yeej tshwj xeeb, xws li kev ua kom pom tsis tu ncua, uas tuaj yeem ua lub luag haujlwm nplawm.

4. Vim tias qhov txo qis hauv pH thaum lub sij hawm plating, nws yog ib qho tsim nyog yuav tsum tsis tu ncua xyuas tus nqi pH thiab kho nws nrog dej ammonia.

5. Ntxiv cov kua tank. Xam tag nrho cov kev daws teeb meem ua haujlwm zoo txheeb ze rau thaj tsam ntawm lub coated workpiece siv lub sij hawm plating ntawm ib teev thiab lub peev xwm thauj khoom ntawm 1dm2 / L · h raws li qhov ntsuas (ceeb toom: tsis yog tag nrho cov dej da dej). Tom qab ntawd ntxiv 10 feem pua ​​​​ntawm tag nrho cov dej ua haujlwm. Nyob ntawm qhov xwm txheej ntawm qhov chaw, txhua yam khoom siv ntxiv tuaj yeem yaj hauv dej ua ntej ntxiv, lossis nws tuaj yeem yaj hauv dej ua haujlwm ua ntej ntxiv. Tom qab cov txheej txheem saum toj no tiav lawm, ntxiv cov tshuaj plating rau hauv txoj hauj lwm teev nrog dej, kho tus nqi pH, thiab txuas ntxiv plating tom qab pom.

6. Kev tu lub plating da dej tsis tu ncua yuav tsum tau ua, thiab lub sij hawm ntxuav ntawm chav da dej yuav tsum nyob ntawm qhov chaw ua hauj lwm ntawm qhov chaw thiab qhov hnyav ntawm cov av ntawm phab ntsa da dej. Tom qab soaking lub plating da dej hauv 3 feem pua ​​dilute nitric acid, txhuam los yog yaug nrog dej huv.

5, Post processing

Nyob ntawm cov xim uas yuav tsum tau ua ntawm qhov chaw ua haujlwm, passivation (dub dub) lossis tsis passivation (grey dub) tuaj yeem ua tiav. Thaum kawg, foob nrog HH932 lub cev qhuav dej los tiv thaiv xeb roj lossis pob tshab kua roj vanish. Cov txheej txheem passivation tuaj yeem pom hauv "Cov Lus Qhia rau HH118-7 Tshuaj Dub Nickel Plating Passivation Solution".
