Galvanizing inoreva tekinoroji yekurapa pamusoro pekuisa zingi pamusoro pesimbi, alloy kana zvimwe zvinhu kuti itambe zvinoyevedza uye ngura kudzivirira.
Zinc inonyungudika zviri nyore mumaasidhi pamwe nealkali, saka inodaidzwa kunzi amphotropic metal.Zinc inochinja zvishoma mumhepo yakaoma.Mumhepo ine mwando, firimu rakakora re alkaline zinc carbonate rinoumbwa pamusoro pezinc.Mu sulfur dioxide, hydrogen sulfide uye Marine atmosphere, zinc corrosion resistance is urombo, kunyanya mutembiricha yepamusoro uye humidity yakakwira ine organic acid atmosphere, zinc coating iri nyore kuita ngura. Iyo yakajairwa electrode kugona kwe zinc ndeye-0.76V, yesimbi matrix, zinc coating ndeye anodic coating, inonyanya kushandiswa kudzivirira kukora kwesimbi, kuita kwayo kwekudzivirira uye ukobvu hwekuputira kunoenderana zvakanyanya.Zinc coating after passivation kurapwa, kusvibiswa kana kuvharwa nechiedza chekudzivirira mumiriri, inogona kuvandudza zvakanyanya kudzivirira kwayo uye kushongedza.
Cold galvanizing
Cold galvanizing, inonziwo electrogalvanizing, iko kushandiswa kwemidziyo ye electrolytic mushure memafuta, pickling, zinc munyu mumhinduro, uye kubatanidza iyo yakaipa electrode ye electrolytic midziyo, iri mhiri kwe zinc plate, yakabatana kune yakanaka electrode ye electrolytic. midziyo simba, kushandisa ikozvino kubva zvakanaka kune yakaipa achaisa dhishizi zingi pamusoro pombi, inotonhora plating pombi inotanga kugadziriswa pashure galvanizing.
Mechanical galvanized
Mudhiramu rinotenderera rine plating, girazi bhora, zinc poda, mvura uye inosimudzira, bhora regirazi sekukanganisa kwepakati rinotenderera nedhiramu, kukweshera uye sando pamusoro peplating inoburitsa mechanic simba remuviri.Pasi pechiito chemakemikari anosimudzira, iyo yakavharwa zinc poda "inotonhora welding" kune yakavharwa pamusoro, ichigadzira yakatsetseka, yunifomu uye yakadzama coating ine humwe ukobvu.
Hot-galvanized
Nzira huru yesimbi plate surface galvanizing ndiyo inopisa-dip galvanizing.
Kupisa galvanizing kwakagadzirwa kubva kunzira dzechinyakare uye kune makore zana nemakumi manomwe kubva payakashandiswa mumaindasitiri muna 1836.Zvisinei, iyo inopisa-dip galvanized industry yakagadziridzwa pamwero mukuru pamwe chete nekukasira kuvandudzwa kwesimbi inotonhora inokungurutswa. mumakore makumi matatu apfuura.
The kugadzirwa muitiro inopisa kwakakurudzira ndiro rinonyanya kusanganisira: yepakutanga ndiro pre-plating inopisa dip post-kurapwa apedza chigadzirwa kuongorora, etc.According netsika, maererano akasiyana plating kurapwa nzira, inopisa dip galvanizing muitiro akakamurwa kunze mutsetse. uye annealing mukati memutsara annealing.
