1. Kho cov txheej txheem electroplating tsis
nruj me ntsis tswj tus nqi pH ntawm cov yob lojgalvanized hlauda dej, kev tshawb fawb qhia tau hais tias qhov loj ntawm da dej pH tus nqi ncaj qha cuam tshuam rau qhov zoo ntawm steel hlau txheej, kev tswj tsis zoo ntawm pH tus nqi yuav ua rau xoob txheej.Thaum tus nqi pH ntau dua 3, cov hlau hlau txheej muaj burr tshwm sim los ntawm cov dendrites zoo, thiab qhov saum npoo tsis du.Qhov ceev tam sim no yog tswj nruj heev.Los ntawm microscopic morphology, qhov siab dua tam sim no, qhov loj dua zinc txheej nplej deposition, qhov tsawg ntom ntawm cov zinc txheej.
Ntawm qhov tsis sib xws, qhov denser ion deposition, qhov zoo ntawm zinc txheej.Raws li qhov xwm txheej uas cov zinc txheej saum npoo yog ntom thiab ci, qhov zoo ntawm zinc txheej hauv ib cheeb tsam yuav tsum ncav cuag 80g / m2, thiab cov txheej txheem yuav tsum tau ua kom zoo raws li hauv qab no: qhov ceev tam sim no yog 16-20A / dm2, qhov loj ntawm zinc. sulfate tov yog 500g / L, thiab pH tus nqi yog 2.5-3.0.
2. Kho cov txheej txheem kev kos duab ntawm lub tank dej
Nyob rau hauv nruj raws li lub multi-pass me me compression tus nqi kos duab, tag nrho compression tus nqi yog 96.48%, txo cov scraping ntawm zinc txheej.Tag nrho cov hlau kos duab tuag yog ua los ntawm tungsten steel tuag thiab polycrystalline tuag.Lub kaum sab xis ntawm lub khob hliav qab ntawm cov hlau kos duab tuag yog 12 ° ~ 16 °, thiab qhov ntev ntawm txoj siv sizing yog 0.15 ntawm txoj kab uas hla ntawm cov xaim, thiaj li yuav xyuas kom meej tias qhov deformation ntawm zinc txheej yog qhov pib synchronous nrog cov steel hlau substrate.
Lub tshuab cua txias siv cov tshuaj tsuag kom txias cov duab kos, thiab tshem tawm ntau cov cua sov uas tsim los ntawm lub tshuab kos duab hauv kev kub ceev hauv lub sijhawm los xyuas kom meej qhov zoo ntawm cov hlau.Tswj cov txheej txheem kev kos duab: kos duab nrawm 10 ~ 12m / s;Winding nro 8 ~ 10N;Ntsuas qhov ntev 30km;Qhov loj feem ntawm cov roj nplua nyeem yog 3.5 ~ 4.5%;pH tus nqi ntawm cov roj nplua nyeem 7 ~ 8;Lubricant kub 30 ~ 40 ℃.
Tom qab kev ua kom zoo ntawm cov txheej txheem, cov khoom loj ntawm 0.80mm electrogalvanized steel hlauelectro galvanized zinc txheej zoo yog tswj tsis pub dhau 80 ~ 90g / m2, zinc txheej zoo dispersion tsawg heev;Cov txiaj ntsig tau pom tias qhov nruab nrab qhov hnyav ntawm zinc txheej yog 14.5g / m2, qhov poob ntawm zinc txheej yog tsawg dua 5%, thiab lub zog tensile ntawm steel hlau yog 2300 ~ 2500MPa.Nws tsis tsuas yog tswj tau zoo ntawm zinc txheej ntawm raw steel hlau, tab sis kuj txo cov khoom pov tseg thiab cov nqi tsim khoom.
