Kev ua haujlwm ntawm Electroless Nickel Plating rau Electroplating Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob

Cov txheej txheem ntawm electroless npib tsib xee plating ua haujlwm yog cuam tshuam nrog kev daws ntawm electroless nickel plating. Feem ntau, electroless npib tsib xee plating kev daws teeb meem yog nyob rau hauv stainless hlau los yog yas plating tso tsheb hlau luam nrog nruam pom thiab huab cua agitation.

Lub pretreated thiab catalytically active yam uas yuav tsum tau plated yuav hnov ​​​​mob rau deposit npib tsib xee los yog npib tsib xee alloys nyob rau hauv cov tshuaj muab tso rau hauv lub plating tank.

Cov txheej txheem ntawm electroless npib tsib xee plating yog txawv los ntawm electroplating npib tsib xee. Nrog rau qhov tshwm sim ntawm cov tshuaj tiv thaiv ntawm electroless npib tsib xee plating, qhov concentration ntawm npib tsib xee ions thiab txo cov neeg ua hauj lwm hauv cov tshuaj plating yuav txo qis mus txog thaum lawv tas;

Thaum lub sij hawm nickel electroplating, npib tsib xee ions hauv da dej tuaj yeem txuas ntxiv ntxiv los ntawm anodic dissolution, thiab lawv cov concentration tseem nyob ruaj khov.

Nyob rau hauv cov txheej txheem ntawm electroless npib tsib xee plating, npib tsib xee ions thiab txo cov neeg ua hauj lwm yuav tsum tau muab ntxiv tas li los yog tsis tu ncua, thiaj li hais tias cov muaj pes tsawg leeg ntawm cov da dej thiab cov muaj pes tsawg leeg ntawm deposited txheej nyob rau hauv lub hauv paus tsis hloov nyob rau hauv lub neej ntawm da dej, txwv tsis pub qhov zoo ntawm lub da dej. txheej tsis tuaj yeem lav.

Pretreatment ntawm Electroless Nickel Plating rau Electroplating Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob

Ua ntej electroless npib tsib xee plating, qhov saum npoo pretreatment ntawm cov khoom hlau yuav tsum tau plated suav nrog cov txheej txheem xws li kev sib tsoo thiab polishing, degreasing, xeb tshem tawm, thiab ua kom muaj zog. Cov txheej txheem pretreatment feem ntau siv hauv electroless nickel plating zoo ib yam li cov hauv electroplating.

Ntawm lawv, kev sib tsoo thiab tshuab polishing yog cov txheej txheem machining ntawm leveling nto ntawm workpiece yuav tsum plated; degreasing thiab xeb tshem tawm yog tshem tawm cov roj stains thiab xeb ntawm qhov chaw ntawm lub workpiece yuav tsum tau plated, kom cov txheej txheej plating tuaj yeem ua ke kom ruaj khov;

Kev ua kom muaj zog yog kom tau txais lub ntsej muag tag nrho ntawm qhov yuav tsum tau plated kom catalyze cov tshuaj tiv thaiv electroless plating.
