Kupisa-dip galvanizing, inozivikanwawo sehot-dip galvanizing, inonyungudutsa zinc inopisa-dip galvanizing ingot pakupisa kwepamusoro,

inoisa zvimwe zvinhu zvekubatsira, uyezve inonyudza chikamu chesimbi mutangi rinogadzira, kuitira kuti zinc layer

yakanamatira kune chikamu chesimbi.Kubatsira kwekupisa-dip galvanizing ndiko kugona kwayo kwe-anti-corrosion kwakasimba, uye

iyo yekunamatira uye kuoma kweiyo galvanized layer zviri nani.Izvo zvisingabatsiri ndezvokuti mutengo wakakwirira, midziyo yakawanda

uye nzvimbo inodiwa, chimiro chesimbi chakakura uye chakaoma kuisa mu galvanizing tangi, chimiro chesimbi chiri

yakanyanya kusimba, uye kupisa-dip galvanizing kuri nyore kukanganisa.Zinc-rich coatings kazhinji inoreva anti-corrosion coatings

ine zinc powder.Zinc-rich coatings pamusika ine one zinc content.Unoda kuziva ukobvu hwezinc

anogona kushandisa nzira dzinotevera

Magnetic nzira

Iyo magnetic method inzira isingaparadzi yekuedza.Inoitwa maererano nezvinodiwa zve

GB/T 4956. Inzira yekuyera ukobvu hwezinc layer nekushandisa electromagnetic ukobvu geji.

Zvakakodzera kutaura pano kuti iyo yakachipa iyo michina inogona kunge iri, iyo yakakura kukanganisa kunogona kuyerwa.Mutengo

yegeji yeukobvu inotangira kuzviuru kusvika kumakumi ezviuru, uye zvinokurudzirwa kushandisa midziyo yakanaka yekuyedza.

kuyera nzira

Zvinoenderana nezvinodiwa zveGB/T13825, nzira yekuyera inzira yekupokana.Kuwanda kweplating ye

iyo zinc coating yakayerwa neiyi nzira inofanirwa kushandurwa kuita ukobvu hwekufukidzira zvichienderana nekuwanda

yekuvhara (7.2g / cm²).Iyi nzira inzira inoparadza yekuedza.Muchiitiko apo nhamba yezvikamu

isingasviki gumi, mutengi haafanire kubvuma achizengurira nzira yekuyera kana nzira yekuyera ingasanganisira.

kukuvadzwa kwezvikamu uye zvinokonzeresa kugadzirisa mari hazvigamuchirwe kune mutengi.

Anodic dissolution coulometric nzira

Anode-kunyungudutsa nzvimbo shoma yekuputira ine yakakodzera electrolyte mhinduro, kupera kwakakwana kweiyo.

kupfekedza kunotarirwa nekushandurwa kwesero voltage, uye hupamhi hwekuputira hunoverengwa kubva pahuwandu

yemagetsi (mune coulombs) inopedzwa neiyo electrolysis, uchishandisa iyo nguva yekunyungudutsa coating uye Simba.

kushandiswa, kuverenga ukobvu hwekuputira.

Cross-sectional microscopy

Cross-sectional microscopy inzira inoparadza yekuyedza uye inongomiririra poindi, saka haiwanzo.

yakashandiswa, uye inoitwa maererano neGB/T 6462. Nheyo yacho ndeyekucheka sampu kubva kune workpiece kuti iongororwe,

uye mushure mekuisa mukati, shandisa nzira dzakakodzera kukuya, kukwenenzvera uye kuisa chikamu chemuchinjikwa, uye kuyera ukobvu.

yemuchinjiko-chikamu chevharo yekuvhara ine mutongi wakaenzana.
