Kub galvanizing, tseem hu ua kub-dip galvanizing thiab kub-dip galvanizing, yog ib txoj kev zoo ntawm hlau tiv thaiv corrosion, feem ntau yog siv rau hlau lug thiab chaw nyob rau hauv ntau yam industries.Nws yog txheej txheem thev naus laus zis kom tau txais txheej txheej los ntawm immersing steel, stainless hlau, cam khwb cia hlau thiab lwm yam hlau rau hauv molten kua hlau los yog alloy.Nws yog ib txoj kev siv dav siv steel nto kho nrog kev ua tau zoo thiab tus nqi hauv ntiaj teb niaj hnub no.Cov khoom kub-dip galvanized ua si lub luag haujlwm tseem ceeb thiab tsis tuaj yeem hloov pauv hauv kev txo qis corrosion thiab ua kom lub neej ntev, txuag lub zog thiab cov khoom siv hlau.Nyob rau tib lub sijhawm, coated steel kuj yog cov khoom lag luam luv luv nrog cov nqi ntxiv uas tau txais kev txhawb nqa thiab tseem ceeb ntawm lub xeev.
Cov txheej txheem ntau lawm
Kev tsim thiab ua cov galvanized steel kauj tuaj yeem muab faib ua peb kauj ruam tseem ceeb: ua ntej, tag nrho cov kauj ntawm cov hlua hlau yuav tsum tau muab tshem tawm kom xeb thiab tshem tawm cov kab mob ua kom lub ntsej muag ntawm galvanized steel sawb ci thiab huv si;Tom qab pickling, nws yuav tsum tau ntxuav nyob rau hauv ammonium chloride los yog zinc chloride aqueous tov los yog ammonium chloride thiab zinc chloride tov aqueous tov, thiab ces xa mus rau hauv lub kub dip da dej rau galvanizing txheej txheem;Tom qab cov txheej txheem galvanizing tiav lawm, nws tuaj yeem khaws cia thiab ntim khoom.

Kev txhim kho keeb kwm ntawm kub galvanizing
Kub galvanizing tau tsim nyob rau hauv nruab nrab ntawm lub xyoo pua 18th.Nws tau tsim los ntawm cov txheej txheem kub tin plating thiab tau nkag mus rau xyoo pua plaub.Txog rau tam sim no, kub-dip galvanizing tseem yog ib qho kev siv dav thiab siv tau zoo hauv kev tiv thaiv corrosion steel.
Xyoo 1742, Dr. Marouin tau ua ib qho kev sim ua ntej ntawm kub-dip galvanizing hlau thiab nyeem nws ntawm Royal College ntawm Fabkis.
Xyoo 1837, Sorier ntawm Fabkis tau thov rau patent rau kub-dip galvanizing thiab tso tawm lub tswv yim ntawm kev siv galvanic cell txoj kev los tiv thaiv hlau, uas yog, txheej txheem ntawm galvanizing thiab xeb tiv thaiv ntawm hlau nto.Nyob rau hauv tib lub xyoo, Crawford ntawm lub tebchaws United Kingdom tau thov rau patent rau zinc plating siv ammonium chloride ua hnyav.Txoj kev no tau ua raws li tam sim no tom qab ntau qhov kev txhim kho.
Xyoo 1931, Sengimir, tus kws tshaj lij tshwj xeeb hauv kev lag luam metallurgical niaj hnub no, tau tsim lub ntiaj teb thawj zaug kub-dip galvanizing ntau lawm kab rau sawb hlau los ntawm hydrogen txo txoj hauv kev hauv tebchaws Poland.Txoj kev tau patented nyob rau hauv lub tebchaws United States thiab cov industrial kub-dip galvanizing ntau lawm kab muaj npe tom qab Sengimir tau tsim nyob rau hauv lub tebchaws United States thiab Maubuge Hlau thiab Steel Cog nyob rau hauv Fabkis nyob rau hauv 1936-1937, raws li, tsim ib tug tshiab era ntawm tas mus li, siab- ceev thiab zoo kub-dip galvanizing rau sawb hlau.
Nyob rau xyoo 1950 thiab 1960, Tebchaws Meskas, Nyiv, Tebchaws Askiv, Lub Tebchaws Yelemees, Fabkis, Canada thiab lwm lub tebchaws tau ua tiav ua cov ntawv hlau aluminized.
Thaum xyoo 1970, Bethlehem Hlau thiab Hlau Tuam Txhab tau tsim cov khoom siv Al-Zn-Si txheej nrog lub npe lag luam Galvalume, uas muaj kev tiv thaiv corrosion ntawm 2-6 npaug ntawm cov zinc txheej ntshiab.
Nyob rau xyoo 1980s, kub dip zinc-nickel alloy tau nrov nrov hauv Tebchaws Europe, Amelikas thiab Australia, thiab nws cov txheej txheem tau raug hu ua Technigalva Tam sim no, Zn-Ni-Si-Bi tau tsim los ntawm lub hauv paus no, uas tuaj yeem cuam tshuam cov tshuaj tiv thaiv Sandelin. thaum kub plating ntawm silicon-muaj hlau.
Nyob rau xyoo 1990, Nyiv Nisin Steel Co., Ltd. tau tsim cov zinc-aluminium-magnesium txheej khoom nrog lub npe lag luam ntawm ZAM, nws qhov kev tiv thaiv corrosion yog 18 npaug ntawm cov txheej txheem zinc txheej, uas yog hu ua plaub tiam ntawm high corrosion. resistant txheej khoom.

Khoom nta

Khoom siv
Kub dip galvanized khoom yog dav siv nyob rau hauv ntau lub teb.Lawv qhov zoo yog tias lawv muaj lub neej ntev los tiv thaiv corrosion thiab tuaj yeem hloov mus rau ntau qhov chaw ib puag ncig.Lawv yeej ib txwm ua ib txoj kev kho corrosion nrov.Nws yog dav siv nyob rau hauv lub zog ntauwd, kev sib txuas lus ntauwd, railway, kev loj tiv thaiv, txoj kev teeb ncej, marine Cheebtsam, lub tsev steel qauv Cheebtsam, substation auxiliary chaw, lub teeb kev lag luam, thiab lwm yam.
