Kupisa Dip Galvanized Channel Steel
Nheyo yeGalvanized Channel Steel Hot-dip galvanized layer inoumbwa nematanho matatu e zinc mune yakanyanya tembiricha yemvura mamiriro:
1. Pamusoro pesimbi yesimbi inonyungudutswa nemvura ye zinc kuti iite zinc-iron alloy phase layer;
2. Ioni dzezinc muchikamu chealloy dzinowedzera kupararira kune substrate kuita zinc-iron mutual dissolving layer;
3. Pamusoro peiyo alloy layer yakakomberedzwa nezinc layer.
(1) Iyo ine gobvu uye dense yakachena zinc layer yakavhara pamusoro pesimbi, iyo inogona kudzivirira kusangana kwesimbi substrate nechero corrosive solution uye kudzivirira substrate yesimbi kubva mukuora.Mumamiriro ekunze, iyo yakaonda uye dense zinc oxide layer inoumbwa pamusoro peiyo zinc layer, iyo yakaoma kunyungudika mumvura, saka ine imwe mhedzisiro yekudzivirira pane substrate yesimbi.Kana zinc oxide uye zvimwe zvinhu zviri mumhepo zvikaita insoluble zinc salt, iyo corrosion protection effect inonyanya kunaka.
(2) Iine iron-zinc alloy layer, yakasanganiswa ne compactness, inoratidza yakasarudzika corrosion kuramba mumakungwa munyu yekupfapfaidza mamiriro ekunze uye maindasitiri mamiriro;
(3) Nekuda kwechisungo chakasimba, zinc-iron inonyungudika, uye ine kusakara kwakasimba;
(4) Nokuti zinc ine ductility yakanaka, uye alloy layer yaro inonamira zvakasimba kune hwaro hwesimbi, inopisa-yakanyikwa zvikamu zvinogona kuumbwa nekutonhora kwekubaya, kukunguruka, kudhirowa kwewaya, uye kukotama pasina kukuvadza coating;
