Kub dipped galvanized steel yeeb nkab yog nyob rau hauv kev tsim cov txheej txheem siv cov kav hlau uas tshem tawm xeb dipped rau hauv zinc kua ntawm 500 degree kub, thiab ua steel nto txuas zinc txheej thiaj li ua tiav lub hom phiaj ntawm kev tiv thaiv corrosion.
Galvanized steel yeeb nkab yog cov yeeb nkab steel uas tau coated nrog zinc. Cov txheej no tiv thaiv cov hlau los ntawm corrosion. Nws yog feem ntau siv rau kev tsim kho sab nraum zoov xws li laj kab thiab tes tuav, lossis rau qee qhov kav dej sab hauv. Nws kuj yog qee zaum hu ua galvanized hlau yeeb nkab.
Cov txheej txheem ntawm galvanization yog thawj zaug tham los ntawm cov kws tshawb fawb hauv xyoo 1770, ze li 60 xyoo ua ntej nws tau tshaj tawm thaum xyoo 1830. Fabkis engineer Stanislaus Tranquille Modeste Sorel tau tawm thawj patent rau tus txheej txheem hauv xyoo 1937, thiab pib tsim nws sai sai tom qab. Los ntawm xyoo 1850, Tebchaws Europe tau tsim cov hlau galvanized tawm ntawm cov chaw tsim khoom nyob ib puag ncig sab av loj. Tebchaws Asmeskas ua raws li tsis ntev tom qab ntawd, qhib nws thawj tsob ntoo hauv xyoo 1870s.
Nyob rau hauv nruab nrab mus rau lig 1900s tooj liab hloov galvanized steel raws li cov khoom xaiv nyob rau hauv cov yeeb nkab fittings.
Nyob rau hauv nruab nrab mus rau lig 1900s tooj liab hloov galvanized steel raws li cov khoom xaiv nyob rau hauv cov yeeb nkab fittings.
Txhawm rau tsim cov yeeb nkab steel galvanized, cov ntaub ntawv hlau raug muab tso rau hauv ib da dej ntawm zinc. Cov txheej txheem no tseem hu ua kub dip galvanization. Ob lub hlau yog chemically khi rau ib leeg nyob rau hauv cov txheej txheem no, thiab yog li ntawd yuav tsis sib cais, ua rau ib tug ntau resistant thiab ntev version ntawm steel.
Hom yeeb nkab no tsis haum rau cov kab hluav taws xob, tab sis feem ntau yog siv rau tag nrho cov kav dej hauv tsev kom txog rau thaum nruab nrab mus txog rau xyoo 1900s, thaum tooj liab hloov nws ua cov khoom siv yeeb nkab. Nws tau pom nyob rau lub sijhawm ntawd tias cov txiv qaub nplai tsim tshwm sim sai dua hauv cov yeeb nkab steel galvanized dua li tooj liab lossis yas. Nws tseem yog qee zaum siv sab hauv tsev rau cov kav dej, tshwj xeeb tshaj yog rau kev hloov chaw me me ntawm cov yeeb nkab, uas qhov ntws yuav tsis cuam tshuam zoo heev los ntawm ntu ntawm cov txiv qaub nplai.
