Musiyano uripo pakati pe electro-galvanizing uye inopisa-dip galvanizing

Iyo simbi yepamusoro inowanzove ine galvanized layer, iyo inogona kudzivirira simbi kubva kune imwe nhanho.Iyo galvanized layer yesimbi inowanzo vakwa nekupisa-dip galvanizing kana electro-galvanizing.Saka ndezvipi zvakasiyanainopisa-dip galvanizinguye electro-galvanizing?

Electro Galvanizing Process

Electrogalvanizing, inozivikanwawo sekutonhora galvanizing muindastiri, maitiro ekushandisa electrolysis kuumba yunifomu, dense uye yakanyatso bonded simbi kana alloy deposition layer pamusoro peiyo workpiece.

Kana ichienzaniswa nedzimwe simbi, zingi isimbi yakachipa uye inoputirwa zviri nyore.Iyo yakaderera-yakakosha anti-corrosion coating uye inoshandiswa zvakanyanya kuchengetedza zvikamu zvesimbi, kunyanya kubva kumhepo yemhepo, uye yekushongedza.Maitiro ekuputira anosanganisira tangi plating (kana rack plating), barrel plating (yezvikamu zvidiki), bhuruu plating, otomatiki plating uye inoenderera plating (yewaya, tambo).

Zvinhu zve electro-galvanized

Chinangwa che electrogalvanizing ndechekudzivirira zvinhu zvesimbi kubva pakusvibiswa, kuvandudza kusagadzikana kwemarara uye hupenyu hwebasa resimbi, uye panguva imwechete kuwedzera kutaridzika kwekushongedza kwechigadzirwa.Simbi ichakanganiswa, mvura kana kuparara kwevhu nekufamba kwenguva.Simbi iyo yakasvibiswa gore negore muChina inokwana chikamu chimwe chete chegumi chehuwandu hwesimbi.Nokudaro, kuitira kuchengetedza hupenyu hwebasa resimbi kana zvikamu zvayo, electro-galvanizing inowanzoshandiswa kugadzira simbi.

Sezvo zinc isiri nyore kuchinja mumhepo yakaoma, uye inogona kubudisa firimu yezinc carbonate inokosha munzvimbo ine unyoro, iyi firimu inogona kudzivirira zvikamu zvemukati kubva pakuparara kwekuora, kunyange kana zinc layer yakakuvadzwa nechimwe chinhu.Mune zvimwe zviitiko, zinc nesimbi zvinosangana nekufamba kwenguva kugadzira microbattery, ine simbi matrix yakachengetedzwa se cathode.Summary Electrogalvanizing ine zvinotevera maitiro:

1. Kuramba kwakanaka kwekuora, kungwarira uye yunifomu musanganiswa, hazvisi nyore kupindwa negasi rinoparadza kana mvura.

2. Nemhaka yokuti zinc layer inenge yakachena, hazvisi nyore kusvibiswa mu acid kana alkali environment.Kunyatso chengetedza muviri wesimbi kwenguva yakareba.

3. Mushure mokunge passivation ne chromic acid, inogona kushandiswa mumarudzi akasiyana-siyana, ayo anogona kusarudzwa maererano nezvinodiwa nevatengi.Iyo galvanizing inoyevedza uye inoshongedza.

4. Iyo zinc coating ine ductility yakanaka uye haizopunzike nyore panguva dzakasiyana dzekukotama, kubata uye kukanganisa.

Ndeupi musiyano uripo pakati pekupisa-dip galvanizing uye electro-galvanizing

Nheyo dzezviviri zvakasiyana.Electrogalvanizing kuisa galvanized layer pamusoro pesimbi nenzira ye electrochemical.Kupisa-dip galvanizingndiko kunyudza simbi mumushonga we zinc kugadzira pamusoro pesimbi ine galvanized layer.

Pane kusiyana pakuonekwa pakati pezviviri izvi.Kana simbi iri electro-galvanized, nzvimbo yaro iri nyore.Kana simbi ichipisa-dip galvanized, nzvimbo yayo yakaoma.Electro-galvanized coatings kazhinji 5 kusvika 30μm, uye kupisa-dip galvanized coatings kazhinji 30 kusvika 60μm.

Chiyero chekushandisa chakasiyana, inopisa-dip galvanizing inonyanya kushandiswa musimbi yekunze senge mafenzi emigwagwa, uye electro-galvanizing inonyanya kushandiswa musimbi yemukati senge mapaneru.
