Kuzivikanwa kweelectrogalvanized steel grating uye inopisa-dip galvanized steel grating

Kare, musiyano pakati pe electrogalvanized steel grating uye inopisa-dip galvanized steel grating yainyanya kuvimba nekuongorora kwekunzwa kwe zinc spangles. Zinc spangles (Zinc spangles) zvinoreva kutaridzika kwetsanga dzakaumbwa mushure mekunge simbi inopisa-dip yaburitswa mupoto itsva uye zinc layer yatonhora nekuoma. Naizvozvo, pamusoro peinopisa-dip galvanized simbi gireti kazhinji yakakasharara, ine yakajairwa zinc spangles, nepo pamusoro pe electrogalvanized simbi grating yakatsetseka. Nekudaro, nekuvandudzwa kwetekinoroji nyowani, hot-dip galvanized simbi grating haichina hunhu hweakajairwa zinc spangles. Dzimwe nguva pamusoro pekupisa-dip galvanized steel grating inopenya uye inopenya kupfuura iyo ye electrogalvanized steel grating. Dzimwe nguva, kana hot-dip galvanized steel grating uye electrogalvanized steel grating zvakaiswa pamwechete, zvakaoma kusiyanisa kuti ndeipi inopisa-dip galvanized steel grating uye inova electrogalvanized steel grating. Naizvozvo, zviviri izvi hazvigone kusiyaniswa nechitarisiko parizvino.

Iko hakuna nzira yekuzivisa yekusiyanisa nzira mbiri idzi dzekukurudzira muChina kana kunyangwe pasirese, saka zvakafanira kudzidza nzira yekusiyanisa maviri kubva kumudzi wedzidziso. Wana mutsauko pakati pezviviri kubva pamusimboti we galvanizing
, uye kuasiyanisa kubva kuvapo kana kusavapo kweZn-Fe alloy layer mune essence. Kana yangosimbiswa, inofanirwa kuve yechokwadi. Nheyo yekupisa-dip galvanizing yezvigadzirwa zvesimbi ndeyekunyudza zvigadzirwa zvesimbi mushure mekuchenesa uye activation mune yakanyungudutswa zinc fluid, uye kuburikidza nekuita uye kupararira pakati pesimbi uye zinc, zinc alloy coating ine yakanaka adhesion inoputirwa pamusoro pezvigadzirwa zvesimbi. Kuumbwa kweiyo inopisa-dip galvanizing layer ndiyo nzira yekugadzira iron-zinc alloy pakati pesimbi matrix uye yekunze yakachena zinc layer. Kunamatira kwayo kwakasimba kunogadzirisawo kurwisa kwayo kwakanakisa. Kubva pachimiro chemicroscopic, inoonekwa seyakagadzika-maviri.
Nheyo ye electrogalvanizing yesimbi grating zvigadzirwa ndeye kushandisa electrolysis kugadzira yunifomu, dense, uye yakanyatso bonded simbi kana alloy deposition layer pamusoro penzvimbo dzesimbi grating zvikamu, uye kugadzira coating pamusoro peiyo simbi grating, kuitira kuti iwane nzira yekudzivirira simbi simbi kubva mukuora. Naizvozvo, electro-galvanized coating imhando yejasi rinoshandisa mafambiro emagetsi emagetsi kubva kune yakanaka electrode kuenda kune negative electrode. Zn2+ mu electrolyte nucleates, inokura uye inoisa pane simbi grating substrate pasi pechiito chekugona kuumba galvanized layer. Mukuita uku, hapana nzira yekuparadzanisa pakati pe zinc ne iron. Kubva pakuona microscopic, ichokwadi yakachena zinc layer.
Muchidimbu, kupisa-dip galvanizing kune iron-zinc alloy layer uye yakachena zinc layer, nepo electro-galvanizing inongova yakachena zinc layer. Kuvapo kana kusavapo kwesimbi-zinc alloy layer mumucheka ndiyo nheyo huru yekuziva nzira yekuputira. Metallographic nzira uye XRD nzira inonyanya kushandiswa kuona iyo yekubatisa kusiyanisa electro-galvanizing kubva inopisa-dip galvanizing.
