1. Gadzirisa electroplating process parameters
Nyatsodzora iyo pH kukosha kwehombe rollgalvanized wirekugeza, tsvakurudzo inoratidza kuti saizi bhati pH ukoshi anokanganisa zvakananga kunaka simbi waya unhani, zvisina kufanira kudzora pH ukoshi kuchaita vakasununguka unhani.Kana iyo pH yakakosha kupfuura 3, iyo simbi waya yekupotera ine burr inokonzerwa neakanaka dendrites, uye pamusoro haina kutsetseka.Ikozvino density inodzorwa zvakanyanya.Kubva pane microscopic morphology, iyo yakakwira density iripo, iyo zinc layer yezviyo yakakurisa, iyo inoenderana neiyo zinc layer.
Pane zvinopesana, iyo denser iyo ion deposition, zviri nani kunaka kwezinc layer.Pasi pemamiriro ekuti iyo zinc layer ine dense uye yakajeka, mhando ye zinc layer pane imwe unit nzvimbo inofanirwa kusvika 80g/m2, uye maparameter ekuita anofanirwa kugadziridzwa sezvizvi: ikozvino density ndeye 16-20A / dm2, huwandu hwezinc. Sulfate solution i500g/L, uye pH kukosha i2.5-3.0.
2. Gadzirisa maitiro ekudhirowa parameters yetangi remvura
Mukunyatsoenderana ne-multi-pass small compression rate yekudhirowa, iyo yakazara compression rate ndeye 96.48%, ichideredza kukwenya zinc layer.Iyo yese waya yekudhirowa inofa yakagadzirwa netungsten simbi inofa uye polycrystalline inofa.Iyo Angle yekoni yekushanda yewaya yekudhirowa kufa ndeye 12 ° ~ 16 °, uye kureba kwebhandi rekuyera ndeye 0.15 yedhayamita yewaya, kuitira kuti ive nechokwadi chekuti deformation ye zinc layer inowirirana ne simbi wire substrate.
Iyo inotonhorera yekutenderera sisitimu inoshandisa pfapfaidzo kutonhodza iyo yekudhirowa kufa, uye inobvisa kwakawanda kupisa kunogadzirwa nemuchina wekudhirowa mukumhanyisa kudhirowa nenguva kuti ive nechokwadi chemhando yewaya.Kudzora kudhirowa maitiro paramita: kudhirowa kumhanya 10 ~ 12m/s;Kupeta tension 8 ~ 10N;Kuyera kureba 30km;Chikamu chikuru chemafuta ndeye 3.5 ~ 4.5%;pH kukosha kwe lubricant 7 ~ 8;Lubricant tembiricha 30 ~ 40 ℃.
Mushure mekugadzirisa kwemaitiro, kugadzirwa kwakawanda kwe0.80mm electrogalvanized steel wayaelectro galvanized zinc layer quality inodzorwa mukati me80 ~ 90g/m2, zinc layer quality dispersion idiki kwazvo;Mhedzisiro yacho inoratidza kuti avhareji huremu hwezinc layer ndeye 14.5g/m2, kurasikirwa kwezinc layer iri pasi pe5%, uye kusimba kwesimba resimbi waya i2300 ~ 2500MPa.Iyo haingodzoreri zvinobudirira kunaka kwezinc layer yewaya yesimbi, asi zvakare inoderedza zvisina kufanira tsvina uye mutengo wekugadzira.
