Cov ntim loj galvanized hlau galvanizing yog ua rau muaj teeb meem dab tsi

Muaj cov khoom siv hauv cov tshuaj plating.Yog hais tias lub ntug thiab qhov kawg ntawm qhov chaw yog ntxhib, nws yuav yog hais tias qhov tam sim no ceev yog loj heev.Yog tiasgalvanized txheejyog zoo, tab sis nyob rau hauv 3% nitric acid lub teeb, lub txheej muaj ib tug tsaus nti ntxoov ntxoo, passivation zaj duab xis tshwm xim av, tej zaum yuav galvanized kua tooj liab los yog txhuas thiab lwm yam hlau impurities.Ua ntej txheeb xyuas qhov kub thiab qhov ceev tam sim no, thiab tom qab ntawd los ntawm kev tshuaj ntsuam da dej, txiav txim siab thiab kho cov ntsiab lus ntawm zinc thiab sodium hydroxide hauv da dej, DPE cov ntsiab lus tsawg, tuaj yeem nkag siab los ntawm kev ntsuas lub tank.

galvanized hlau

Yog tias txheej roughness tsis yog cov laj thawj saum toj no, nws tuaj yeem tshwm sim los ntawm impurity hauv cov tshuaj plating, tuaj yeem siv me me ntawm cov tshuaj plating, thiab lim tom qab kev sim, tom qab ntawd siv me me ntawm cov tshuaj plating, sim cov zinc hmoov ua tiav. , xyuas seb puas yog cov khoom tsis zoo lossis tooj liab, txhuas, thiab lwm yam hlau impurities sib txawv, cov khoom los ntawm cov khoom, kev sim, nws tsis nyuaj rau nrhiav qhov ua tsis tiav.Kev tshem tawm cov roj tsis tiav lossis acid corrosion yuav ua rauloj galvanized hlautxheej hlwv.

Tab sis lub ntsiab yog vim li cas rau hom da dej no yog ib qho yooj yim rau npuas yog adsorption ntawm cov organic additives nyob rau hauv lub siv lead ua nto ntawm txheej, thiaj li hais tias tus thawj siv lead ua los yog ib co siv lead ua nto tsis tuaj yeem loj hlob ib txwm, uas ua rau kev loj hlob txawv txav ntawm cov siv lead ua tshiab. los yog ib co crystal nto;Los yog cov organic additives nyob rau hauv cov txheej txheej clip, cuam tshuam cov txheej txheem ib txwm ntawm cov lattice, ua rau cov lattice distortion, yog li ua rau kev ntxhov siab sab hauv ntawm txheej txheej, ua rau txheej txheej bubbling.
