Tsanangudzo yekugadzira
HDG kazhinji inoreva kupisa-dip galvanizing. Kupisa-dip galvanizing kuita kuti simbi yakanyungudutswa iite pamwe nesimbi matrix kuti ibudise alloy layer, kuitira kuti matrix uye coating zvibatane. Kupisa-dip galvanizing ndiko kutanga kunyura simbi nesimbi, kuitira kubvisa iron oxide pamusoro pesimbi nesimbi, mushure mekutora, inocheneswa mutangi reammonium chloride kana zinc chloride aqueous solution kana aqueous solution. yakasanganiswa aqueous solution yeammonium chloride uye zinc chloride, yozotumirwa kune inopisa dip coating tank. Kupisa-dip galvanizing kune zvakanakira kupfeka yunifomu, kunamatira kwakasimba uye hupenyu hurefu hwebasa.
Iyo countersunk head of hot dip galvanized bolts inowanzoshandiswa panodiwa kubatana. Iyo isiri-yakajairwa chikamu muchimiro cheU uye nekudaro inozivikanwawo seU-bolt. Kupisa-dip galvanized mabhaudhi ane shinda kumagumo ese anogona kushandiswa pamwe chete nenzungu. Iyo utility modhi inonyanya kushandiswa kugadzirisa tubular kana flaky zvinhu.
Kudzivirirwa kwekuora kunonyanya kutariswa nehupamhi hwemagalvanized layer, saka kuyerwa kwehukobvu kazhinji ndiyo nheyo huru yekutonga kunaka kwegirodhi. Iko kona uye nekukurumidza kwemhinduro kunewo simba guru. Naizvozvo, hazvigoneke kuwana yakazara yunifomu yekupfeka ukobvu.
