Hauv kev lag luam steel, cov kav hlau steel yog cov khoom siv tseem ceeb thiab tau siv dav hauv kev tsim kho, tshuab, tshuaj lom neeg kev lag luam, thiab lwm yam. Cov yeeb nkab steel alkali ntxuav cov txheej txheem, raws li qhov txuas tseem ceeb hauv kev kho cov kav dej steel, yog qhov tseem ceeb rau kev txhim kho cov kev ua haujlwm ntawm cov kav hlau steel thiab txuas ntxiv lawv lub neej kev pab cuam.
Ua ntej, lub hauv paus ntsiab lus ntawm cov yeeb nkab steel alkali ntxuav txheej txheem
Alkali ntxuav, raws li lub npe qhia, yog ib txoj hauv kev los ntxuav cov kav hlau uas siv cov tshuaj alkaline. Thaum lub sij hawm alkali ntxuav, cov hydroxide ions (OH-) nyob rau hauv cov tshuaj alkaline react chemically nrog impurities xws li cov roj stains thiab oxides ntawm cov yeeb nkab steel, hloov lawv mus rau hauv cov dej-soluble tshuaj, yog li ua tiav lub hom phiaj ntawm kev ntxuav. nto. Nyob rau tib lub sijhawm, kev ntxuav alkali kuj tseem tuaj yeem tshem tawm qhov microscopic tsis sib xws ntawm cov yeeb nkab steel nto, muab lub hauv paus zoo rau cov txheej txheem tom ntej lossis kev kho corrosion.
Thib ob, cov kauj ruam ntawm cov yeeb nkab steel alkali ntxuav txheej txheem
Cov yeeb nkab steel alkali ntxuav cov txheej txheem feem ntau suav nrog cov kauj ruam hauv qab no:
1. Pretreatment: Ua ntej ntxuav alkali, cov yeeb nkab steel yuav tsum tau pretreated, nrog rau tshem tawm cov impurities loj thiab xeb ntawm qhov chaw. Lub hom phiaj ntawm cov kauj ruam no yog tsim kom muaj qhov chaw ua haujlwm huv si rau kev ntxuav alkali thiab txhim kho cov nyhuv ntawm alkali ntxuav.
2. Kev npaj cov tshuaj Alkali: Raws li cov khoom siv, qhov chaw saum npoo, thiab kev tu kom huv ntawm cov yeeb nkab steel, npaj cov tshuaj alkaline uas tsim nyog. Ntau dhau los yog tsawg dhau ntawm cov tshuaj alkali yuav cuam tshuam rau kev ntxuav, yog li nws yuav tsum tau tswj nruj me ntsis.
3. Alkali ntxhua khaub ncaws: Muab cov yeeb nkab steel pretreated hauv cov tshuaj alkali rau ib lub sijhawm kom cov tshuaj alkali tuaj yeem tiv tauj thiab ua rau lub ntsej muag ntawm cov yeeb nkab steel. Thaum lub sij hawm tus txheej txheem no, cov yeeb nkab steel yuav tsum tau tig tsis tu ncua kom ntseeg tau tias txhua qhov chaw raug ntxuav kom sib npaug.
4. Kev ntxuav thiab ziab: Tom qab ntxuav cov alkali tiav, cov yeeb nkab steel yuav tsum tau muab yaug nrog dej huv kom tshem tawm cov khoom seem alkali thiab cov tshuaj tiv thaiv. Tom qab rinsing, cov yeeb nkab steel yuav tsum tau qhuav kom tsis txhob muaj kev puas tsuaj los ntawm cov khoom seem.
5. Kev tshuaj xyuas zoo: Thaum kawg, cov yeeb nkab steel tom qab ntxuav alkali raug tshuaj xyuas kom ntseeg tau tias nws qhov chaw huv si, glossiness, thiab lwm yam raws li tus qauv yuav tsum tau ua. Yog tias muaj cov khoom tsis tsim nyog, lawv yuav tsum tau rov ua dua.
Thib peb, cov ntsiab lus ntawm cov yeeb nkab steel alkali tu txheej txheem
Hauv kev ua haujlwm tiag tiag, txhawm rau ua kom muaj txiaj ntsig thiab zoo ntawm cov yeeb nkab steel alkali ntxuav, cov ntsiab lus hauv qab no yuav tsum raug sau tseg:
1. Xaiv cov tshuaj alkali kom raug: Cov khoom siv steel yeeb nkab sib txawv thiab cov txheej txheem saum npoo muaj qhov sib txawv ntawm cov kev daws teeb meem alkali. Yog li ntawd, thaum xaiv cov tshuaj alkali, nws yog ib qho tsim nyog yuav tsum xav txog qhov tseeb ntawm cov yeeb nkab steel thiab xaiv qhov tsim nyog alkali tov hom thiab concentration.
2. Tswj lub sij hawm ntxuav alkali: lub sij hawm tu alkali ntev dhau lawm yuav ua rau muaj kev xeb ntau dhau ntawm cov yeeb nkab steel thiab cuam tshuam rau kev ua haujlwm; Lub sij hawm luv luv yuav tsis raug ntxuav kom huv. Yog li ntawd, nws yog ib qho tsim nyog yuav tau txiav txim siab lub sij hawm ntxuav alkali raws li cov khoom siv thiab qhov chaw paug ntawm cov yeeb nkab steel.
3. Tuav lub alkali tov kub: Thaum lub sij hawm alkali ntxuav txheej txheem, qhov tsim nyog kub yuav ua rau kom cov tshuaj tiv thaiv tus nqi, yog li txhim kho kev tu efficiency. Txawm li cas los xij, qhov kub thiab txias dhau yuav ua rau cov tshuaj alkali evaporate sai heev, cuam tshuam rau kev ntxuav. Yog li ntawd, qhov kub thiab txias alkali yuav tsum tau khaws cia nyob rau hauv ib qho chaw tsim nyog.
4. Tsis tu ncua hloov cov tshuaj alkali: Raws li kev ntxuav alkali ua tiav, cov khoom xyaw zoo hauv cov tshuaj alkali yuav maj mam noj, thiab qee qhov ntawm cov impurities yuav sib sau. Txhawm rau ua kom cov nyhuv tu, cov tshuaj alkali yuav tsum tau hloov tsis tu ncua.
5. Kev tiv thaiv kev nyab xeeb: Alkali tov yog corrosive thiab irritating rau qee yam. Cov neeg ua haujlwm yuav tsum hnav tsom iav tiv thaiv, hnab looj tes, thiab lwm yam khoom tiv thaiv kev ua haujlwm kom tsis txhob muaj kev sib cuag ncaj qha nrog cov tshuaj alkali. Nyob rau tib lub sijhawm, cov chaw ua pa yuav tsum tau teeb tsa ntawm qhov chaw ntxhua khaub ncaws alkali kom txo tau qhov teeb meem ntawm alkali tov volatilization rau cov neeg ua haujlwm.
Plaub, qhov tseem ceeb thiab tus nqi ntawm cov yeeb nkab steel alkali ntxuav txheej txheem
Raws li qhov txuas tseem ceeb hauv kev tsim cov yeeb nkab steel, cov yeeb nkab steel alkali ntxuav cov txheej txheem yog qhov tseem ceeb rau kev txhim kho cov kav hlau zoo thiab txuas ntxiv lawv lub neej kev pab cuam. Los ntawm kev kho alkali ntxuav, impurities xws li roj thiab oxides ntawm cov kav dej steel tuaj yeem raug tshem tawm tau zoo, thiab kev ua kom huv thiab tiv thaiv corrosion ntawm cov kav hlau tuaj yeem txhim kho. Nyob rau tib lub sijhawm, kev ntxuav alkali kuj tuaj yeem txhim kho microstructure ntawm cov yeeb nkab steel nto, muab lub hauv paus zoo rau cov txheej tom ntej los yog kev tiv thaiv corrosion. Yog li ntawd, nyob rau hauv tus txheej txheem ntawm steel yeeb nkab ntau lawm, tag nrho cov xim yuav tsum tau them mus rau lub alkali ntxuav txuas kom ntseeg tau tias qhov zoo ntawm steel kav raws li tus qauv yuav tsum tau.
