Iyo anti-corrosion kurapwa kwewaya mesh fencemambure anowanzo kukamurwa kuva marudzi maviri: imwe iri kunyura uye imwe yacho inopisa-dip galvanizing. Iyo yekunyudza kurapwa mesh yefenzi ipurasitiki yekuputira maitiro. Mushonga wekunyudza wakakamurwa kuita dipping inopisa uye kunyura kunotonhora zvichienderana nekuti kudziya kwakakosha here. Zvinoenderana neiyo yekutanga data yekunyudza, inogona kukamurwa kuita yemvura dipping uye hupfu. Iyo inoenderana yekugadzirisa yakakamurwa kuita yemvura dipping processing uye poda dipping processing. Cold dipping equipment inowanzova mhando yewekishopu. Dipping inopisa inodiwa kuti ichidziswe gore rose. Kazhinji maworkshop madiki anoshandisa kunyura kunotonhora nekunyudza. Inogona kukamurwa kuva mavara akati wandei: rima rakasvibira uswa hwakasvibirira, ruvara rwebhuruu uye zvichingodaro.
Kushandiswa kwe-hot-dip galvanizing ye mesh yefenzi inogadzirwa kubva kune yenguva refu inopisa-dip door nzira. Ine nhoroondo yemakore 140 kubvira France yakaisa galvanizing inopisa-dip kuindasitiri muna 1836. Zvisineyi, indasitiri yekupisa-dip galvanizing yakawana budiriro huru nekusimukira nekukurumidza kwesimbi inotonhora mumakore makumi matatu apfuura.
Nzira yekugadzira inopisa-dip galvanized sheet inonyanya kusanganisira: yepakutanga bhodhi kugadzirira → pre-plating kurapwa → kupisa-dip plating → post-plating kurapwa → kupedza kuongorora chigadzirwa, etc. Maererano netsika, iyo inopisa-dip galvanizing process inokamurwa kuita zvikamu zviviri: kunze-kwe-line annealing uye mu-line annealing kusiyana kwekutanga kweplating. Kubatsira kwekupisa-dip galvanizing fence ndeyekuti ine nguva yakareba yekudzivirira-corrosion, uye kugadzirisa kune zvakatipoteredza kwagara kwave kwakakurumbira kurapa-anti-corrosion. Kupisa-dip galvanizing kune hupenyu hurefu hunopesana nemashiripiti, asi hupenyu hwekurwisa-mashiripiti hwakasiyana munzvimbo dzakasiyana:
Nheyo yekupisa-dip galvanizing: chenesa mativi esimbi, wozonyungudutsa mushonga, kunyudza mumvura yezinki mushure mekuoma, simbi inopindirana neyakanyungudutswa zinc kuti iite alloyed zinc layer, maitiro acho ndeaya: degreasing-water washing-pickling- Batsira plating-kuomesa-hot dip galvanizing-kupaza-kupatsanura. Ukobvu hweiyo inopisa-dip galvanized alloy layer inonyanya kuenderana nesilicon yemukati uye zvimwe zvemakemikari zvikamu zvesimbi, iyo mhiri-chikamu nzvimbo yesimbi, kushata kwesimbi, tembiricha yepoto yezinc, nguva yekuputira, kumhanya kwekutonhora, uye kutonhora kutenderedza deformation.
