Reaction mechanism rau kev daws teeb meem acidic tooj liab plating rau saum npoo ntawm hluav taws xob cua sov raj
1. Kev daws teeb meem ntawm acidic tooj liab plating ntawm cov khoom ABS
Qhov saum npoo ntawm txheej yog ntxhib
(1) Qhov ceev tam sim no siab dhau lawm. Nws yuav tsum raug txo kom tsim nyog.
(2) Tsis txaus sulfuric acid thiab additives nyob rau hauv lub plating tov. Yuav tsum tau ntxiv kom tsim nyog
Kab txaij nyob rau saum npoo ntawm txheej
(1) Muaj cov impurities hauv cov tshuaj plating. Nws yuav tsum tau lim los yog kho nrog hydrogen peroxide thiab activated carbon.
(2) Muaj ntau ntau yam additives nyob rau hauv lub plating tov. Kev tshuaj xyuas thiab kev kho yuav tsum tau ua
Tsis zoo nto brightness ntawm txheej
(1) Qhov ceev tam sim no tsawg dhau. Nws yuav tsum tau nce kom tsim nyog.
(2) Muaj cov impurities hauv cov tshuaj plating. Nws yuav tsum tau lim los yog kho nrog hydrogen peroxide thiab activated carbon.
(3) Tsis txaus additives nyob rau hauv lub plating tov. Yuav tsum tau ntxiv kom tsim nyog
Tsis zoo dispersibility
(1) Cov ntsiab lus sulfuric acid hauv cov tshuaj plating tsis txaus. Nws yuav tsum tau muab ntxiv kom tsim nyog.
(2) Lub anode tooj liab phaj yog me me. Yuav tsum tau nce kom tsim nyog.
(3) Cov ntsiab lus ethanol hauv cov tshuaj plating tsis txaus. Yuav tsum tau nce kom tsim nyog
2. Kev daws teeb meem ntawm alkaline tooj liab plating ntawm cov khoom ABS
Tsis tag nrho plated
(1) Lub sensitizer thiab activator tsis huv. Yuav tsum tau siv cov tshuaj tshiab.
(2) Tus nqi pH ntawm cov tshuaj plating yog tsawg dhau. Diluted sodium hydroxide yuav tsum tau siv rau kev hloov kho.
(3) Kev daws tsis tau thiab yuav tsum tau hloov nrog ib qho tshiab.
(4) Cov concentration ntawm tus neeg sawv cev txo qis heev. Qhov tsim nyog ntawm formaldehyde yuav tsum tau ntxiv
Ib feem plating tsis ua hauj lwm
(1) Ua tsis tiav coarsening thiab tsis zoo hydrophilicity. Kev kho ntxhib yuav tsum tau ua dua.
(2) Kev ua tsis tiav thiab kev ua kom tiav. Lub sijhawm rhiab heev thiab lub sijhawm ua haujlwm yuav tsum raug ncua kom tsim nyog.
(3) Formaldehyde yog huab heev. Kev hloov pauv yuav tsum tau ua.
(4) Cov ntsiab lus ntawm formaldehyde thiab sodium hydroxide hauv cov tshuaj yog tsawg dhau. Yuav tsum tau ntxiv kom tsim nyog
Tsis zoo adhesion ntawm txheej thiab cov khoom substrate
(1) Plating daws tsis ua hauj lwm. Yuav tsum tau siv cov tshuaj tshiab.
(2) Cov roj tsis zoo tshem tawm thiab coarsening ntawm cov khoom. Nws yuav tsum tau reprocessed.
(3) Cov ntsiab lus ntawm formaldehyde thiab sodium hydroxide yog siab, thiab tooj liab plating ceev ceev heev. Cov ntsiab lus ntawm formaldehyde thiab sodium hydroxide yuav tsum raug txo kom tsim nyog.
(4) Lub plating tov kub yog siab dhau. Yuav tsum tau txo kom tsim nyog
3. Kev daws teeb meem ntawm Bright Nickel Plating ntawm qhov chaw ntawm AlDS cov khoom
Roughness thiab pitting ntawm qhov chaw ntawm txheej
(1) Qhov ceev tam sim no siab dhau lawm. Nws yuav tsum raug txo kom tsim nyog.
(2) Muaj av nkos seem ntawm lub anode. Lub phaj anode yuav tsum tau ntxuav.
(3) Muaj ntau cov chlorides. Nws yuav tsum raug txo kom tsim nyog.
(4) Cov ntsiab lus ntub dej tsis txaus. Yuav tsum tau ntxiv kom tsim nyog
Muaj cov qauv ntawm cov txheej txheej
(1) Cov ntsiab lus tsis txaus ntawm sodium dodecyl sulfonate. Nws yuav tsum tau muab ntxiv kom tsim nyog.
(2) Tsis zoo dissolution ntawm sodium dodecyl sulfonate. Kev kho electrolytic yuav tsum tau ua.
(3) Tus nqi pH ntawm cov tshuaj plating yog siab dhau. Yuav tsum tau txo kom tsim nyog
Tsaus txheej saum npoo thiab hlawv ntawm cov ces kaum
(1) Cov ntsiab lus brightener siab dhau los yog qhov sib piv tsis raug. Yuav tsum tau kho kom haum.
(2) Qhov ceev tam sim no siab dhau lawm. Yuav tsum tau txo kom tsim nyog
Qhov sib sib zog nqus concave ntawm cov plated qhov chaw tsis ci
(1) Qhov ceev tam sim no tsawg dhau. Nws yuav tsum tau nce kom tsim nyog.
(2) Lub plating tov kub yog siab dhau. Nws yuav tsum raug txo kom tsim nyog.
(3) Cov ntsiab lus tsis txaus ntawm butynediol brightener. Yuav tsum tau nce kom tsim nyog.
(4) Tus nqi pH ntawm cov tshuaj plating tsis ua raws li cov txheej txheem yuav tsum tau ua. Yuav tsum tau kho kom haum
Tsis zoo flatness thiab glossiness ntawm txheej
(1) Cov ntsiab lus brightener tsis txaus. Yuav tsum tau nce kom tsim nyog.
