Yuav ua li cas los daws qhov teeb meem ntawm cov tshuaj nickel plating cov dej khib nyiab hauv kev cob qhia nrog hluav taws xob cua sov raj

Dab tsi yog qhov kev kho mob nyuaj ntawm cov tshuaj npib tsib xee plating cov dej khib nyiab uas ua rau nws nyuaj rau lub tiaj ua si zom?

Qhov no yuav tsum pib nrog cov txheej txheem txheej txheem, plating tov mis, thiab cov pa paug paug ntawm cov tshuaj npib tsib xee plating.

Cov txheej txheem tshuaj nickel plating yog ib txoj hauv kev uas tsis tas yuav muaj hluav taws xob. Raws li lub hauv paus ntsiab lus ntawm redox cov tshuaj tiv thaiv, cov txo tus neeg sawv cev sodium hypophosphate yog siv los txo cov npib tsib xee ions rau hauv cov xim hlau npib tsib xee hauv cov tshuaj uas muaj cov hlau nickel ions, uas tau tso rau ntawm ntau yam khoom siv los tsim cov txheej tuab. Nws yog tam sim no dav siv nyob rau hauv kev lag luam xws li aerospace, automotive kev lag luam, hluav taws xob computers, ua zaub mov, thiab lwm yam.

Nyob rau hauv cov tshuaj nickel plating tov, npib tsib xee sulfate yog tsuas yog siv raws li lub ntsiab ntsev, citric acid, lactic acid, malic acid, thiab lwm yam yog siv raws li complexing agents, sodium hypophosphate yog siv raws li ib tug txo tus neeg sawv cev, thiab ammonia yog siv raws li ib tug pH. tsis pub. Yog li, kev kho dej khib nyiab yuav cuam tshuam txog cov teeb meem xws li tag nrho cov npib tsib xee, tag nrho phosphorus, COD, thiab ammonia nitrogen.

Cov teeb meem hauv kev kho cov dej khib nyiab los ntawm cov tshuaj nickel plating feem ntau yog tshwm sim hauv peb yam:

1. Sodium hypophosphate nyob rau hauv cov dej khib nyiab yog ib qho nyuaj heev rau tshem tawm inorganic phosphorus, uas yog ib qho nyuaj rau precipitate thiab tshem tawm los ntawm txiv qaub los yog ib txwm phosphorus tshem tawm cov neeg ua hauj;

2. Cov nickel ions nyob rau hauv cov dej khib nyiab ntawm cov tshuaj nickel plating thiab complexing agents xws li lactic acid yuav tsim ib tug complex daim ntawv ntawm nickel, uas yog ib qho nyuaj rau precipitate thiab tshem tawm nyob rau hauv lub xub ntiag ntawm alkali;

3. Cov dej khib nyiab tsim tawm thaum lub sij hawm hloov lub tank rau cov tshuaj npib tsib xee plating muaj siab heev ntawm tag nrho cov nickel, tag nrho phosphorus, COD, thiab ammonia nitrogen, ua rau nws nyuaj rau kho nws nrog cov tshuaj zoo tib yam kom tau raws li cov qauv.
