Cov phooj ywg zoo tshaj plaws uas tau siv sij hawm nyob rau hauv cov hlau tsim kev lag luam yuav tsum tau to taub cov txheej txheem pickling. Lub pickling yog kom tshem tawm cov oxide zaj duab xis ntawm cov khoom hlau thiab tsim ib txheej ntawm phosphate ntawm lub hlau ntub thaum tshem lub oxide zaj duab xis. Zaj duab xis, tsis ua underestimate txheej txheem ntawm zaj duab xis, ua si lub luag hauj lwm yav tom ntej ntawm cov tshuaj tsuag los yog cov txheej txheem molding. Nws yuav tsum tau hais tias xws li pickling yog zoo li muab ib tug tshiab tiab ntawm lub hlau nto thiab nws yog ib tug tshiab hnav ris tsho uas yuav tsum tau hnav. Txij ntawm no pom, pickling kuj yog ib kauj ruam tseem ceeb rau peb, thiab peb yuav tsum nyob hauv qhov chaw. Peb yuav tsum tsis txhob poob ntsej muag. Ntawm no peb tuaj rau kev nkag siab txog qhov tshwj xeeb ntsia hlau ua cov txheej txheem pickling.
Thawj yog qhov paub txog ntawm qhov concentration thiab qhov kub thiab txias hauv lub pas dej. Hauv qab no, lub disc yog nchuav rau hauv peb lub pas dej npaj ua si. Thawj kauj ruam yog tshem tawm cov oxide zaj duab xis ntawm cov hlau. Qhov thib ob yog los hloov lub pas dej. Cov kauj ruam no yog hu ua dej ntshiab. Lub ntsiab tseem ceeb yog los tshem tawm cov qhov ntxhib corrosive. Qhov thib peb oxalic acid yog kom ua rau kev ua ntawm lub hlau thiab pw lub hauv paus rau tom ntej no ncaj ncees zaj dab neeg. Cov nram no yog peb kauj ruam tseem ceeb tshaj plaws. Phosphate yuav tsum nyob rau hauv kev sib cuag nrog cov saum npoo ntawm cov hlau khoom tsim ib zaj duab xis. Cov nram no yog ib kauj ruam ntawm cov dej ntshiab kom tshem tau cov khoom seem. Cov kauj ruam no yuav zoo li yooj yim, tab sis, thaum ua haujlwm, peb yuav tsum tuav lub sijhawm zoo. Qhov kev zoo li no yuav tsum tau kom tus neeg teb xov tooj kom paub zoo txog sijhawm, txwv tsis pub lub pickling yog kev txiav tawm, tsis muaj qhov tseem ceeb, tom qab ntawd Cov txheej txheem tseem ua tsis tau. Nws tuaj yeem hais tias pickling yog ib lub caij nyoog hloov mus rau kev tsim cov khoom tshwj xeeb. Cov kauj ruam no yuav tsum tau ua kom tiav zoo thiaj li yuav ua tau ib txoj haujlwm zoo ntawm peb cov txheej txheem hauv qab no kom ua tau raws li qee qhov kev xav tau zoo.
