Keeb kwm ntawm galvanizing

Xyoo 1836, Sorel hauv Fab Kis tau coj tawm thawj zaug ntawm ntau patents rau txheej txheem txheej hlau los ntawm dipping nws hauv molten Zinc tom qab thawj zaug ntxuav nws.Nws muab cov txheej txheem nrog nws lub npe 'galvanizing'.
Keeb kwm ntawm galvanizing pib tshaj 300 xyoo dhau los, thaum ib tug alchemist-los-chemist npau suav txog ib tug yog vim li cas rau immerse huv si hlau rau molten zinc thiab rau nws xav tsis thoob, ib tug shimmering nyiaj txheej tsim rau hlau.Qhov no yog los ua thawj kauj ruam nyob rau hauv lub genesis ntawm cov txheej txheem galvanizing.
Zaj dab neeg ntawm zinc yog sib txuas nrog cov keeb kwm ntawm galvanizing;ornaments ua los ntawm alloys uas muaj 80% zinc tau pom nyob deb li deb rov qab li 2,500 xyoo.Brass, ib qho alloy ntawm tooj liab thiab zinc, tau taug qab mus rau tsawg kawg yog xyoo pua 10 BC, nrog Judean tooj dag pom nyob rau lub sijhawm no muaj 23% zinc.
Cov ntawv kho mob Indian nto moo, Charaka Samhita, sau nyob ib ncig ntawm 500 BC, hais txog cov hlau uas thaum oxidised tsim pushpanjan, tseem hu ua 'philosopher's wool', xav tias yog zinc oxide.Cov ntawv sau qhia nws siv los ua tshuaj pleev rau qhov muag thiab kho qhov txhab qhib.Zinc oxide yog siv rau niaj hnub no, rau cov tawv nqaij mob, nyob rau hauv calamine cream thiab antiseptic tshuaj pleev.Los ntawm Is Nrias teb, zinc tsim tau tsiv mus rau Tuam Tshoj nyob rau hauv lub xyoo pua 17th thiab 1743 pom thawj European zinc smelter tau tsim nyob rau hauv Bristol.

Xyoo 1824, Sir Humphrey Davy tau pom tias thaum ob lub hlau tsis sib xws tau txuas nrog hluav taws xob thiab tso rau hauv dej, qhov corrosion ntawm ib qho tau nrawm dua thaum lwm tus tau txais kev tiv thaiv qib.Los ntawm txoj haujlwm no nws tau hais tias cov tooj liab hauv qab ntawm cov nkoj nkoj ntoo (qhov piv txwv ntxov tshaj plaws ntawm kev tiv thaiv cathodic) tuaj yeem tiv thaiv los ntawm kev txuas hlau lossis zinc phaj rau lawv.Thaum cov ntoo hulls tau hloov los ntawm hlau thiab hlau, zinc anodes tseem siv tau.
Xyoo 1829 Henry Palmer ntawm London Dock Company tau tso cai patent rau 'indented lossis corrugated metallic sheets', nws qhov kev tshawb pom yuav muaj kev cuam tshuam loj heev rau kev tsim qauv thiab galvanizing.
