Kupisa galvanizing, inozivikanwawo se-hot-dip galvanizing uye inopisa-dip galvanizing, inzira inoshanda yekudzivirira kwesimbi corrosion, inonyanya kushandiswa kune zvivakwa zvesimbi uye zvivakwa mumaindasitiri akasiyana siyana.Inyanzvi yekugadzira tekinoroji yekuwana coating nekunyudza simbi, simbi isina tsvina, simbi yakakandwa uye mamwe masimbi muyakanyungudutswa yemvura simbi kana alloy.Iyo inowanzoshandiswa simbi pamusoro pekurapa nzira nekuita zvirinani uye mutengo munyika nhasi.Zvigadzirwa zvinopisa-dip galvanized zvinoita basa risingaverengeki uye risingadzokerike mukuderedza ngura uye kurebesa hupenyu, kuchengetedza simba uye zvinhu zvesimbi.Panguva imwecheteyo, simbi yakavharwa zvakare chigadzirwa chenguva pfupi chine kukosha kwakawedzerwa kunotsigirwa uye kunokosheswa nehurumende.
Nzira yekugadzira
Kugadzirwa uye kugadziridzwa kwemarara esimbi coil inogona kukamurwa kuita matanho makuru matatu: chekutanga, iyo yese coil ye strip simbi ichave yakanyungudutswa yekubvisa ngura uye kusvibiswa kuita kuti pamusoro perata yakabatiswa simbi inopenya uye yakachena;Mushure mekunhonga, inofanira kucheneswa muammonium chloride kana zinc chloride aqueous solution kana ammonium chloride uye zinc chloride yakasanganiswa aqueous solution, yozotumirwa mubhati rinopisa rekugezera kuti rive galvanizing process;Mushure mekuita kwekugadzika kwapera, inogona kuchengetwa uye kuputirwa.

Nhoroondo yekuvandudza yekupisa galvanizing
Kupisa galvanizing kwakagadzirwa pakati pezana remakore rechi18.Yakagadzirwa kubva kune inopisa tin plating process uye yapinda muzana ramakore rechina.Kusvika parizvino, kupisa-dip galvanizing kuchiri kushandiswa zvakanyanya uye kunoshanda nzira yekudzivirira mukuora kwesimbi.
Muna 1742, Dr. Marouin akaita chiedzo chokutanga pamusoro pekupisa-dip galvanizing yesimbi uye akaiverenga paRoyal College yeFrance.
Muna 1837, Sorier yeFrance yakanyorera patent yekupisa-dip galvanizing uye akaisa pfungwa yekushandisa galvanic cell nzira kuchengetedza simbi, ndiko kuti, nzira yekunamisa uye kudzivirira ngura pamusoro pesimbi.Mugore rimwe chetero, Crawford wekuUnited Kingdom akanyorera patent ye zinc plating achishandisa ammonium chloride se solvent.Iyi nzira yakateverwa kusvika ikozvino mushure mekuvandudzwa kwakawanda.
Muna 1931, Sengimir, injinjini yakatanhamara muindasitiri yemazuva ano yesimbi, akavaka mutsara wekugadzira wepasirese wekutanga kupisa-dip galvanizing wesimbi ye strip nenzira yekuderedza haidrojeni muPoland.Iyo nzira yaive patented muUnited States uye indasitiri inopisa-dip galvanizing yekugadzira mutsara wakatumidzwa zita rekuti Sengimir yakavakwa muUnited States uye Maubuge Iron uye Steel Plant muFrance muna 1936-1937, zvichiteerana, ichigadzira nguva nyowani yekuenderera, yakakwirira- kumhanya uye yemhando yepamusoro inopisa-dip galvanizing ye strip simbi.
Mumakore ekuma1950 nema1960, United States, Japan, Britain, Germany, France, Canada nedzimwe nyika dzakatevedzana dzakagadzira mahwendefa esimbi ane aluminium.
Mukutanga kwema1970, Bethlehem Iron and Steel Company yakagadzira iyo Al-Zn-Si coating material ine zita rekutengesa rekuti Galvalume, iro riine corrosion resistance ye2-6 times yeyakachena zinc coating.
Mumakore ekuma1980, hot dip zinc-nickel alloy yakakurumidza kukurumbira muEurope, America neAustralia, uye maitiro ayo akanzi Technigalva Parizvino, Zn-Ni-Si-Bi yakagadziridzwa pachikonzero ichi, iyo inogona kumisa zvakanyanya kuita kweSandelin. panguva inopisa yekuputira yesilicon-ine simbi.
Mumakore ekuma1990, Japan Nisin Steel Co., Ltd. yakagadzira zinc-aluminium-magnesium coating material ine zita rekutengesa reZAM, iro rinopesana nekuora rakapetwa ka18 kune yechinyakare zinc coating, iyo inonzi chizvarwa chechina chekuora kwepamusoro. resistant coating material.
