Galvanized wiremukushandiswa kwenguva yakati rebei, pamusoro pechidzitiro chinopfumbuka, chinodonha, saka chinokanganisa kunaka kwewaya yakanyungudutswa, kungorega pamusoro peiyo galvanized layer ichibviswa, mushure mekupukuta, kupfekedzwa zvakare, saka. sekuona kuti galvanized wire iwedzere kushandiswa kwenguva refu.
Chokutanga pane zvose, kudiwa kwe sodium hydroxide 200 ~ 300g / L sodium nitrite 100 ~ 200g / L mvura kuwedzera kune 1L kuitira kuti iwe ubvise zvikamu zvakanyanya kudiwa uye simbi yesimbi uye zvichingodaro.Iyo tembiricha yekurapa ndeye 100 ℃, uye nguva iri kusvika pakucheneswa.
Kudzivirirwa kwe zinc coating pane iron matrix ine misimboti miviri: kune rumwe rutivi, kunyangwe zinc iri kushanda uye iri nyore kuita oxidize kupfuura iron, asi iyo oxide firimu haina kusununguka uye compact se iron oxide.Iyo dense oxide layer inoumbwa pamusoro pepamusoro inodzivirira kuwedzera oxidation ye zinc mukati.Kunyanya mushure mekupfuura kwegalvanizedlayer, pamusoro peiyo oxide layer yakanyanya kukora uye dense, pachayo ine yakakwirira oxidation kudzivirira.
Ukuwo, kana pamusoro pegalvanizedlayer yakakuvadzwa, ichifumura iyo yemukati simbi matrix, nekuti zingi inoshanda kupfuura simbi, panguva ino, zinc inotakura basa rekupira zinc anode, zinc ichave oxidized pamberi pesimbi, kuitira kuchengetedza iron layer haizokuvadzwa.
