Dab tsi yog cov teebmeem tshwj xeeb ntawm stirring thiab ncig ntawm qhov ruaj ntseg ntawm electroless Nickel-phosphorus plating txheej?

Stirring thiab ncig yog cov haujlwm tseem ceeb uas cuam tshuam rau kev ruaj ntseg ntawm cov txheej txheem npib tsib xee ntawm cov txheej txheem plating
Kuv {. tus cawv ntawm stirring hom thiab siv
{{01. Tsis txhob muaj cov tshuaj tiv thaiv hauv zos
Cuam Tshuam Mechanism: Tshuaj Nickel-phosphorus plating yog qhov kev cuam tshuam nrog tus kheej), tshwj xeeb yog nyob rau hauv qhov kev sib cav sib ceg tov .
Kev Ua Haujlwm Kev Ua Haujlwm:
Siv cov khoom siv sib xyaw (xws li tshuab nplawm, cua nplawm lossis muab cov kev faib tawm ntawm lub cev thiab tsis txhob muaj kev sib raug zoo .
Tswj Stirring kev siv: Tsis yooj yim siv tau yooj yim coj mus rau kev tso tawm ntawm cov khoom seem (xws li plating seem, cov khoom sib txawv); Kev siv dhau lawm yuav rhuav tshem kev ruaj khov ntawm plating daws interface, thiab txawm tias muaj oxygen interface (xws li hypophosphite), txo lub neej ntawm cov plating tov .
2. Tswj cov kev sib txuam ntawm kev sib xyaw ntawm plating kua
Cuam Tshuam Mechanism:
Thaum cov nickel ions, hypophosphhaphites, chelating cov neeg sawv cev tsis muaj zog yog qhov ua rau muaj kev puas tsuaj hauv lub pH yog qhov ua rau muaj kev puas tsuaj rau kev txo qis kev ua kom tiav .
Tsis txaus ntseeg yuav ua rau cov khoom siv hydrogen (los ntawm cov khoom lag luam) tsim los ntawm cov tshuaj tiv thaiv kab mob, tab sis kuj tseem yuav ua qhov zoo ntawm cov kev txiav txim siab ntawm cov plating.
Kev Ua Haujlwm Kev Ua Haujlwm:
Xyuas kom meej tias nplawm tau txuas ntxiv sib xyaw cov kev daws teeb meem, tshwj xeeb yog tom qab ntxiv cov tshuaj, txaus tsim kom tsis txhob muaj cov tsis huv ntawm cov khoom lag luam .
Siv Directional stirring (xws li raws li qhov kev coj ua ntawm lub cev tank) kom txo cov dej khov kho thiab tuag thiab txhim kho kev ua kom zoo .
{{02. Lub luag haujlwm thiab kev cuam tshuam ntawm cov kev ncig ncig
1. pom kev thiab kev tshem tawm ntawm kev tawm tsam
Cuam Tshuam Mechanism:
Cov khoom siv tau raug tshem tawm hauv cov txheej txheem plating (xws li categrefulity lim (xws li polypropylene lim cov khoom lag luam) kom txo qis kev pheej hmoo ntawm tus kheej-catalytic Kev txiav txim siab .
Yog tias cov kev taug kev ntws tsis txaus, lub zog los khaws cia nyob hauv lub tsev ua haujlwm lossis lub zog ua haujlwm rau hauv zos qhov kev txiav txim siab tsis zoo lossis plating daws kev sib cav sib ceg.
Kev Ua Haujlwm Kev Ua Haujlwm:
Tsim kev ua kom pom kev txuas ntxiv nrog qhov tseeb ntawm feem ntau 1 ~ 5 μm, thiab hloov lub lim dej tsis tu ncua kom ntseeg tau tias cov nyhuv uas pom tseeb.
Rau high-thauj khoom lag luam, xws li co coarse pageBon adsorption khoom siv kom tshem tawm cov khoom siv cov organic (xws li phosphites decomposition (xws li phosphites).
2. kub tswj thiab kev tswj hwm
Cuam Tshuam Mechanism:
Cov txheej txheem ncig ua si tuaj yeem tswj qhov kub ntawm qhov kub thiab kub ua kom muaj kev hloov pauv ntawm cov phiaj xwm ua kom sov siab dua
Yog tias qhov kev ncig khiav tsis txaus, qhov ceev ntawm qhov chaw cua sov ntws los ntawm cov raj cua kub (xws li tuaj yeem ua rau nyob ze cov raj cua sov (uas tau ua kom muaj kev kub ntxhov yooj yim
Kev Ua Haujlwm Kev Ua Haujlwm:
Xyuas kom meej tias cov kev ncig ntws tawm cov ntawv sib tw rau cov plating tank ntim (feem ntau yog kev pom zoo rau kev sib tw tank / teev) kom ntseeg tau cov kev sib dhos kub.
Siv cov kev tawm tsam kev ncig (xws li ua kua hauv qab ntawm lub tank thiab kua rov qab los ntawm cov khoom ua kua "tuag rau qhov ua kua thiab txhim kho kev tswj kom sov .
{{0 {}} roj emission thiab cov khoom tshem tawm
Kev Cuam Tshuam Mechanism:
Yog tias cov tshuaj hydrogen tsim tawm thaum lub sijhawm ua npuas, lawv yuav ua rau muaj kev sib tsoo lossis kev sib tsoo hauv lub zos ntawm cov kev daws teeb meem; Nyob rau tib lub sijhawm, hydrogen yuav sib xyaw nrog oxygen hauv cov huab cua los ua qhov sib xyaw ua ke (kev nyab xeeb yuav tsum tau them nyiaj rau).
Qhov dhau los lossis kev tso tawm ntawm cov txheej txheem ncig tau tuaj yeem tshem tawm hydrogen ntau thiab txo cov roj kom ruaj khov .
Kev Ua Haujlwm Kev Ua Haujlwm:
Tsim cov raj xa hluav taws xob tsim nyog kom ntseeg tau tias cov roj tso tawm tom qab cov plhaw tank lossis chaw tso pa tawm hauv lub voj voos) .
Zam kev tawm ntawm cov twj tso kua mis los ntawm ntxais hauv huab cua (yog tias cov raj xa hluav taws xob tau muab cov khoom siv oxidation zoo los yog ua kom tsis txhob sib xyaw nrog cov roj av oxidation.
Iii {.} synergistic effect ntawm stirring thiab ncig
1.} Tsis txhob ua tsis tiav ntawm ib qho
Vam khom rau stirring tej zaum yuav ua rau muaj kev kub siab dhau ntawm cov pa hluav taws xob, thaum cia siab nyob rau hauv lub sijhawm tsis muaj peev xwm ua tau los yog kub ntxhov hauv lub sijhawm ntawm ob leeg tuaj yeem ua tiav:
Cov khoom sib txawv: stirring ua kom pom cov kab rov tav sib xyaw ntawm cov plating daws, thiab kev ua tiav tau cov kab xev kom txaus kom npog tag nrho cov plating tank ntim .
Dynamic Tshuav: Sijhawm tshem tawm ntawm cov tshuaj tiv thaiv los ntawm cov khoom lag luam (xws li cov kua dej sib xyaw ua ke los ntawm cov kav dej pipeline) {}
2.} Kev yoog raws cov txheej txheem sib txawv
High-phosphorus plating daws: Feem ntau yooj yim rau decomple, xav tau muaj zog stirring thiab ncig kom muaj kev ruaj khov (xws li cua nplawm) .
Nruab nrab thiab tsawg-phosphorus plating daws tau cov khoom siv tau muaj cai kom raug txo kom zoo, tab sis cov impurities yuav tsum muaj zoo lim.
Kev tsis siv neeg kab txheej txheem: lub zog txav ntawm txhais caj npab yuav tsum tau sib cav sib ceg (xws li Pulse Confersion tswj lossis ntau zaus kev tswj hwm) {}}}}
