Iko kunoshanda kukosha kwekupisa dip galvanizing ye galvanized sheet zvinoenderana nekuti kushorwa kwekupisa kwesimbi inopisa yakakwenenzverwa inovandudzwa zvakanyanya mushure mekuvharwa kweiyo dhipi dip galvanizing, iyo inogona kuchengetedza mbishi zviwanikwa uye zviwanikwa uye kupa kutamba kwakazara kune yakanakisa mabhenefiti ehupfumi uye zvakasikwa mabhenefiti ezvakatipoteredza.
Kiyi yekuchengetedza kushanda kweiyo inopisa dip galvanizing layer yegalvanized sheet yesimbi inopisa yakakungurutswa simbi yakaita seinotevera:
(1) kana iyo gobvu simbi ndiro pamusoro, chete zingi ngura, nekuti zinc corrosion zvinhu zvine yakanaka kugadzirisa mhedzisiro, saka kukora kuri kunonoka, hupenyu hwesevhisi huchave 15-30 nguva dzendiro yesimbi.
(2) Mamiriro akanyanya kuitika ndeye galvanized sheet mukugadzira uye kugadzirisa, kuisirwa, kuiswa, kukwenya kwepamusoro, kana chero chimwe chikonzero iyo layer iri pasi pechikamu chakakanganisika, inopisa yakakungurutswa simbi simbi yakaburitswa kubva paronda munzvimbo yechisikigo, kana ari iwo makemikari. yezvinhu zvisiri zvesimbi, zvidhinha zvakafumurwa zvichadzikwa kure, asi maitiro ekuchengetedza esimbi anotonhora akakungurutswa pepa akasiyana, ita kuti etching rate inonoke, nenzira iyi Zingi iri mukuputira uye simbi muinopisa yakakungurutswa simbi inoumba galvanic. sero munzvimbo yakanyorova uye inotonhora, nekuti chiyero che electrode kugona kwe zinc chete -1.05V, isingasviki -0.036V yesimbi, saka zingi seanodic oxidation nemhepo oxidation, uye simbi sendiro yakaipa kuwana kugadzirisa. Nekuti izvo zvigadzirwa mushure mezinc zvakanyanyisa density, nguva yekuita inononoka, nemamwe mazwi, iyo yakazara corrosion resistance inovandudzwa zvakanyanya. Iyi nzira yekudzivirira inonzi corrosion resistance.
