Kuomarara ndeimwe yeanonyanya kushandiswa indekisi mumakanika zvinhu zvesimbi zvinhu.Iyo inokurumidza uye yehupfumi yekuyedza nzira yekuomarara bvunzo inounzwa muwaya fekitori.Asi nekuda kwekuoma kwezvinhu zvesimbi, hapana tsananguro yakabatana uye yakajeka inosanganisira ese nzira dzekuedza kumba nekune dzimwe nyika.Kazhinji kutaura, kuoma kwesimbi kunowanzo fungwa sekupokana kwechinhu kune deformation yepurasitiki, kukwenya, kupfeka, kana kucheka.
Mukugadzirisa kwekunyura kureba kwehombegalvanized wire, chengetedza kukurumidza kwepakutanga kusina kuchinjwa, uye sarudza nguva yekunyura (1) maererano neT = KD, apo: T ndiyo nguva dzose yenguva yekunyura, tora 4-7d ndiyo dhayamita yewaya yesimbi mm, uye wozofungidzira kunyura. chinhambwe.Nekugadzirisa zinc dipping chinhambwe, zinc dipping time yesimbi waya yemhando dzakasiyana-siyana inopfupiswa ne5s paavhareji pane iyo isati yagadziriswa.Nenzira iyi, kushandiswa kwezinc kunoderedzwa, uye kushandiswa kwezinc patani yewaya yesimbi kunoderedzwa kubva pa61kg kusvika 59.4kg.
Kupisa dip galvanizing iri mukudziya kweyakanyungudutswa zinc dip plating, kukurumidza kwekugadzira, kukoira asi isina kuenzana, ukobvu hwemusika hunobvumira 45 microns, anosvika mazana matatu microns kana kupfuura.Rudzi rwakasviba, kushandiswa kwezingi simbi, uye matrix simbi kuumba infiltration layer, corrosion resistance yakanaka, inopisa galvanized yekunze nharaunda inogona kuchengetedzwa kwemakumi emakore.Pane misimboti miviri yekudzivirira zinc coating pane iron matrix: kune rumwe rutivi, kunyangwe zinc inonyanya kushanda uye iri nyore kuita oxidize pane iron, iyo oxide firimu haina kusununguka sesimbi oxide uye ine dense.Kuumbwa kwedense oxide layer pamusoro pepamusoro kunodzivisa kuwedzera oxidation ye zinc mukati.
Kunyanya mushure mekupfuura kwe galvanized layer, iyo yepamusoro oxide layer inowedzera dense, pachayo ine yakakwira oxidation kuramba.Nekune rimwe divi, kana iyo yekumusoro layer ye zinc coating ikakuvadzwa, ichiratidza mukati mesimbi matrix, nekuti zinc inoshanda zvakanyanya kupfuura iron, zinc inotakura basa rekupira zinc anode, zinc ichaita oxidize pamberi pesimbi, nokudaro ichidzivirira iron layer. kubva mukukuvadzwa.
