Tsis zoo brightness ntawm electroplated txheej ntawm hluav taws xob cua sov raj
Ib txoj hauv kev los tsim cov ntawv hlau electrogalvanized los ua kom lub zog ntawm cov txheej txheem galvanized, suav nrog cov kauj ruam hauv qab no: degreasing steel phaj, tom qab ntawd yaug thiab pickling nrog dej huv, tom qab ntawd electrogalvanizing saum npoo ntawm cov phaj steel kho, thiab ntxiv cov tin uas muaj. 15-8000ppm rau cov tshuaj electroplating. Cov txiaj ntsig zoo ntawm qhov kev tsim tawm tam sim no yog: qhov zoo ntawm cov txheej txheej galvanized yog tiaj tus, ci, tsis muaj kab txaij, thiab muaj qhov zoo adhesion.
Muaj ntau yam thiab nyuaj uas tuaj yeem ua rau muaj qhov tsis zoo thaum lub sij hawm electroplating txheej txheem, xws li theem poob, luv luv Circuit Court lossis cov khoom puas tsuaj ntawm cov khoom siv hluav taws xob, qhov sib txawv ntawm cov khoom siv raw thiab cov khoom siv, thiab lwm yam. yam. Kev tsis saib xyuas cov txheej txheem tshwj xeeb thiab cov txheej txheem ua haujlwm yog ib qho tseem ceeb ntawm tib neeg uas tuaj yeem zam tau. Hauv kev tsim khoom, ntau qhov yuam kev tshwm sim ntau zaus nyob rau tom kawg dua li yav dhau los.
1 Fault piv txwv
1.1 Tsis zoo brightness ntawm txheej
(1) Lub teeb ci tsis zoo ntawm zinc hlau alloy coatings yog ntau. Kuj tseem muaj qhov cuam tshuam tsawg dua, feem ntau yog vim kev txo qis ntawm cov brighteners. Ntxiv tus nqi tsim nyog tuaj yeem txhim kho qhov ci. Yog tias cov nyhuv tsis zoo, koj tuaj yeem ntxiv ntxiv. Ib zaug ntxiv brightener ntau dhau, nws kuj tuaj yeem ua rau lwm yam ua haujlwm tsis zoo. Ua tib zoo saib xyuas kom tsawg thiab ntau zaus, thiab qhov txhaum tuaj yeem raug tshem tawm.
(2) Cov ntsiab lus ntawm cov ntsev tseem ceeb lossis cov ntsev ntsev kuj tuaj yeem cuam tshuam qhov ci ntawm txheej. Nws yog qhov zoo tshaj plaws los soj ntsuam cov khoom tseem ceeb ntawm cov tshuaj plating ua ntej ua ntej kev hloov kho.
(3) Qhov ci ntsa iab tsis zoo ntawm cov txheej kuj qhia tau hais tias tsis tshua muaj cathode tam sim no ceev. Los ntawm qhov tsim nyog nce qhov ceev tam sim no, qhov txhaum tuaj yeem raug tshem tawm.
(4) Cov impurities ntau dhau nyob rau hauv cov tshuaj plating ua rau muaj kev tiv thaiv ntawm cov tshuaj, uas tseem cuam tshuam rau lub ci ci ntawm txheej. Lub brightener muaj cov khoom siv zoo uas muaj cov tooj liab zais thiab cov hlau lead impurities, thiab muaj qee qhov teeb meem uas qhov ci ntsa iab poob vim muaj impurities ntau dhau. Thaum nws tshwm sim, cov tshuaj ua turbid, nrog rau cov txheej ntxhib. Purifying cov tshuaj yog txaus.
