Nhoroondo ye galvanizing

Muna 1836, Sorel yekuFrance yakatora yekutanga pamatendi akawanda ekugadzirisa simbi nekuinyika muZinc yakanyungudutswa mushure mekutanga kuichenesa.Akapa maitiro ane zita rayo 'galvanizing'.
Nhoroondo yekugadzira galvanizing inotanga makore anopfuura 300 apfuura, apo muongorori wemakemikari akarota chikonzero chekunyudza simbi yakachena muzinc yakanyungudutswa uye zvakamushamisa, simbi yaipenya yakanamirwa pasimbi.Iri raizove danho rekutanga mukutanga kwemaitiro ekugadzira.
Nyaya ye zinc yakanyatsopindirana neiyo yenhoroondo ye galvanizing;zvishongo zvakaitwa kubva kune alloys ane 80% zinc zvakawanikwa zvichifambidzana semakore 2,500.Brass, alloy yemhangura uye zinc, yakateverwa kusvika kuzana remakore rechi10 BC, nendarira yeJudhiya yakawanikwa munguva iyi ine 23% zinc.
Chinyorwa chezvekurapa chemuIndia, Charaka Samhita, chakanyorwa makore akapoteredza 500 BC, chinotaura nezvesimbi iyo kana yakasanganiswa neoxidised yakagadzira pushpanjan, inozivikanwawo se'wool's wool', inofungidzirwa kuva zinc oxide.Chinyorwa chacho chinotsanangura kushandiswa kwaro sechizoro chemaziso uye mushonga wemaronda akazaruka.Zinc oxide inoshandiswa nanhasi, kune mamiriro eganda, mune calamine creams uye antiseptic mafuta.Kubva kuIndia, kugadzirwa kwezinki kwakaendeswa kuChina muzana ramakore rechi 17 uye 1743 yakaona yekutanga kunyungudutsa zinc yekuEurope ichigadzwa muBristol.

Muna 1824, Sir Humphrey Davy akaratidza kuti apo simbi mbiri dzakasiyana dzakabatanidzwa nemagetsi ndokunyudzwa mumvura, kukora kweimwe kwaikurumidziswa apo imwe yakawana mwero wakati wedziviriro.Kubva mubasa iri akakurudzira kuti pasi pemhangura dzezvikepe zvemapuranga zvechikepe (muenzaniso wekutanga wekudzivirira kwekathodic) zvinogona kudzivirirwa nekuisa mahwendefa esimbi kana zinc kwazviri.Apo midziyo yemapuranga yakatsiviwa nesimbi nesimbi, zinc anode dzakanga dzichiri kushandiswa.
Muna 1829 Henry Palmer weLondon Dock Company akapiwa patent ye 'indent kana corrugated metallic sheets', kuwanikwa kwake kwaizove nemhedzisiro inoshamisa pakugadzirwa kwemaindasitiri nekuputira.
