Daim ntawv thov ntawm Surfactants nyob rau hauv Electroplating ntawm Hluav Taws Kub Kub Tubes

Dab tsi yog cov teeb meem uas cov tuam txhab electroplating txhawj xeeb tshaj plaws? Xwm yog qhov zoo ntawm electroplating. Lub uniformity, flatness, ceev, zoo glossiness, thiab tsis muaj pinholes thiab pits ntawm txheej yog qhov tsawg kawg nkaus tus qauv rau ib tug zoo plating daim.

Lub ntsiab tseem ceeb uas cuam tshuam rau cov khoom ntawm cov khoom plated, ntxiv rau cov khoom siv electroplating thiab kev tswj cov txheej txheem, kuj yog cov tshuaj electroplating. Txoj kev siv feem ntau thiab siv tau los txhim kho kev ua haujlwm ntawm cov kev daws teeb meem electroplating yog ntxiv cov surfactants rau cov tshuaj plating. Piv txwv li, nyob rau hauv cov tshuaj electroplating formulations, surfactants xws li K-12 (sodium dodecyl sulfate) feem ntau muaj.

Cov teebmeem ntawm surfactants hauv cov tshuaj electroplating yog ntau yam:

Qhov sib ntxiv ntawm surfactants tuaj yeem nthuav dav qhov pH, qhov kub thiab txias tam sim no ntawm cov tshuaj electroplating;

⑵ Nws muaj qhov zoo dispersibility rau cov hlau hais precipitated thaum lub sij hawm electroplating, uas yog zoo rau kev txhim kho lub smoothness thiab brightness ntawm nto ntawm lub plated qhov chaw;

Txo qhov nro saum npoo yog qhov zoo rau ntub cov plating qhov chaw;

(4) Txhawb kom ceev ceev detachment ntawm hydrogen gas generated nyob rau hauv cathode nto, uas yuav tiv thaiv tau cov tsim ntawm pinholes thiab dents nyob rau saum npoo ntawm daim plating;

Tom qab tus neeg saib xyuas qhov chaw ua haujlwm tu, cov nyhuv electroplating ntawm cov plated yog qhov zoo dua, uas tuaj yeem txuag hluav taws xob. Cov txheej txheem tiv thaiv ntawm lub tshuab hluav taws xob piston nplhaib yog tus cwj pwm nyob rau hauv uas nws yog npib tsib xee tungsten ferroboron alloy electroplating txheej. Cov tshuaj muaj pes tsawg leeg ntawm cov tshuaj electroplating yog 30-100g / L nickel sulfate, 25-45g / L sodium tungstate, 20-30g / L boric acid, 20-40g / L sodium citrate , 8-15g/L ferrous sulfate thiab 5-15g/L citric acid. Lub invention siv electroplating txoj kev los hloov hard chromium nrog npib tsib xee tungsten boron hlau alloy, uas tsis muaj ib puag ncig muaj kuab paug, thiab hnav tsis kam ntawm piston nplhaib yog siab dua li ntawm hard chromium txheej. Nyob rau tib lub sij hawm, qhov invention muab cov txheej txheem electroplating ntawm anti-hnav txheej. Lub nplhaib piston tom qab pretreatment yog muab tso rau hauv cov tshuaj electroplating npaj ntawm 60 - 80 degree , thiab pH nyob ruaj khov nyob rau hauv qhov ntau ntawm 7.8 - 8.4 thaum lub sij hawm electroplating txheej txheem, thiab qhov ceev tam sim no yog { {12}}A/dm2.
