Zinc inonzi metallurgical reaction process.Kubva pakuona kwemicroscopic, maitiro ekupisa dip galvanizing maviri ane simba rekuenzanisa, kupisa chiyero uye zinc iron exchange equilibrium.Kana iyo simbi workpiece yakanyudzwa mune inenge 450℃yakanyungudutswa zinc mvura, tembiricha yekamuri yemvura zinc inobata kupisa kweiyo workpiece, inosvika pamusoro pe200℃, kupindirana kwezinc nesimbi kwakava pachena, zinc, iron inopinda pamusoro.Sezvo tembiricha yeworkpiece ichisvika zvishoma nezvishoma tembiricha yezinc yakanyungudutswa, workpiece pamusoro yakaumbwa neyakasiyana chikamu chezinc iron alloy layer, hierarchical chimiro che zinc coating, nekuwedzera nguva, kukura kweakasiyana alloy plating layer inopa kukurumidza kukurumidza.Kubva pane macro maonero, kuita kweiyo iri pamusoro pekuita workpiece yakanyudzwa mumvura zingi, zingi mvura inofashaira inoitika apo zinc, iron reaction zvishoma nezvishoma inodzikama, zinc surface zvishoma nezvishoma yadzikama.Workpiece inogadzirwa.ye zinc pamusoro, tembiricha yekushanda inodzikiswa zvishoma nezvishoma kusvika pasi pe200℃, kuita kwakamiswa ne zinc, iron, inopisa dip galvanized coating ine ukobvu hwakatemwa.

Ukobvu hweiyo zinc yekuputira zvinhu zvikuru: chigadziko chesimbi chikamu, kushata kwesimbi, simbi yezvinhu zvinoshanda silicon uye phosphorus zvemukati uye kugovera, kushushikana kwemukati kwesimbi, iyo workpiece geometry, inopisa-dip galvanizing process. .Izvozvi zvepasi rose uye zveChinese zviyero zvakakamurwa kuita zvikamu zvinoenderana nehupamhi hwesimbi, ukobvu hwezinc coating ukobvu uye dhizaini yemunharaunda inofanirwa kusvika kune inowirirana ukobvu, kuona zinc coating anticorrosion performance.Yakasiyana simbi ukobvu hwebasa rekushanda, kuti uwane kuenzana kwemafuta, uye zinc ion exchange equilibration panguva dzakasiyana, ukobvu hwekuputira hunosiyana.Avhareji ukobvu hweiyo coating standard yakavakirwa pamuchina weiyo galvanizing ruzivo mukugadzirwa kwemaindasitiri, ukobvu hwenzvimbo yezinc coating ukobvu hunotorwa mukufunga kusaenzana kugovera kwekuvhara uye ngura yekudzivirira zvinodiwa ruzivo.Naizvozvo, ISO zviyero, ASTM zviyero, JIS zviyero uye Chinese zviyero zinc coating ukobvu zvinodiwa zvakasiyana zvishoma, zvakafanana.

Ukobvu hweiyo zinc coating inosarudza kushanda kweanticorrosion plating zvikamu.Kune 3 mm pazasi peiyo yakaonda simbi plate yepamusoro inotsvedzerera, zvakaoma kuwana yakakora coating mukugadzirwa kwemaindasitiri, nekuwedzera, haina kuenzana nehupamhi hwesimbi zinc plating ukobvu uye ichakanganisa kusimba kwekunamatira kweiyo coating uye. iyo substrate uye yekupfeka inoratidzika kunaka.Iyo yakakora yekuputira inokonzeresa kutaridzika kweiyo yakaomarara, nyore kupepeta, plating zvikamu hazvigone kumira kudhumhana mukuita kwekubata uye kuisa.Kana paine mamwe masimbi anoshanda esilicon uye phosphorus, kugadzirwa kwemaindasitiri kwave kwakaoma zvakanyanya kutetepa coating, inova iyo silicon yemukati mesimbi inobata pakati pe zinc-iron alloy layer yekukura modhi.
