Kuomarara indekisi yezvivakwa inowanzoshandiswa mumakanika emidziyo yesimbi.Iyo fekitori waya yesimbi inounza inokurumidza uye yehupfumi nzira yekuyedza yekuomarara.Nekudaro, kune kuoma kwezvinhu zvesimbi, hapana tsananguro yakabatana uye yakajeka inosanganisira ese nzira dzekuedza kumba nekune dzimwe nyika.Kazhinji, kuoma kwesimbi kunowanzoonekwa sekupokana kwechinyorwa chepurasitiki deformation, kukwenya, kupfeka, kana kucheka.
Koiri hurugalvanized wiremu zinc kunyudzwa kure debugging, chengetedza yepakutanga kumhanya kusachinjika, maererano t = KD kuona zinc kunyudzwa nguva (1), apo: t ndiyo zinc kunyudzwa nguva inogara, tora 4-7D ndiyo dhayamita yesimbi waya mm. , uye wozofungidzira kureba kwekunyudzwa kwezingi.Nekugadzirisa zinc dip kure, iyo zinc dip nguva yesimbi waya yeakasiyana maratidziro inogona kupfupikiswa ne5s paavhareji.Nenzira iyi, kushandiswa kwezingi patani yewaya yesimbi kunoderera kubva pa61kg kusvika pa59.4kg.
Kupisa dip galvanizing iri mukupisa kunyunguduka zinc liquid dip plating, kukurumidza kugadzirwa, gobvu asi risina kuenzana coating, musika unobvumira ukobvu hwemakumi mana neshanu mamicrons, anosvika mazana matatu microns pamusoro.Yakasviba muruvara, inoshandisa zinc simbi yakawanda, inoita infiltration layer ine base metal, uye ine yakanaka corrosion resistance.Kupisa dip galvanizing kunogona kuchengetedzwa kwemakumi emakore munzvimbo yekunze.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 kwe galvanized layer, pamusoro peiyo oxide layer yakakora uye compact, pachayo ine yakakwira oxidation kuramba.Nekune rimwe divi, kana pamusoro peiyo galvanized layer yakuvadzwa, ichifumura iyo yemukati iron matrix, nekuti zinc inoshanda kupfuura iron, zinc inotakura basa rekupira zinc anode, zinc ichave oxidized pamberi pesimbi, kuitira kudzivirira. iyo iron layer haingakuvadzi.
