Tshwj xeeb galvanized yeeb nkab rau qhov hluav taws xob
Lus piav qhia luv luv:
Galvanized yeeb nkab, tseem hu ua galvanized steel yeeb nkab, muab faib ua kub-dip galvanizing thiab electro galvanizing.Cov txheej kub-dip galvanizing yog tuab thiab muaj qhov zoo ntawm cov txheej txheej, muaj zog adhesion thiab kev pab lub neej ntev.Tus nqi ntawm electro galvanizing yog tsawg, qhov saum npoo tsis du heev, thiab nws cov corrosion kuj yog qhov phem dua li cov yeeb nkab kub-dip galvanized.
Kub dip galvanized steel yeeb nkab
Complex lub cev thiab tshuaj tiv thaiv tshwm sim ntawm cov yeeb nkab steel matrix thiab molten plating tov los tsim ib tug corrosion-resistant zinc ferroalloy txheej nrog compact qauv.Cov txheej txheej hlau yog kev sib xyaw nrog cov zinc txheej ntshiab thiab cov yeeb nkab steel matrix.Yog li ntawd, nws muaj zog corrosion kuj.
Tom qab kev txhim kho los ntawm 1960s txog 1970s, cov khoom zoo ntawm kub-dip galvanized steel yeeb nkab tau zoo heev.Los ntawm 1981 txog 1989, nws tau raug ntsuas tsis tu ncua raws li cov khoom lag luam zoo ntawm Ministry of metallurgy thiab lub teb chaws nyiaj tau txais txiaj ntsig.Cov zis kuj tau nce ntau xyoo.Cov zis ntau tshaj 400000 tons hauv xyoo 1993 thiab ntau tshaj 600000 tons hauv xyoo 1999. Nws tau xa tawm mus rau South Asia, Africa, Tebchaws Meskas, Nyiv, Lub Tebchaws Yelemees thiab lwm lub tebchaws thiab cheeb tsam.Cov kav dej kub dip galvanized feem ntau yog siv los ua cov kav dej xa mus thiab cov kav dej, nrog rau cov lus qhia tshwj xeeb ntawm + 12.5 ~ + 102 hli.Txij li thaum xyoo 1990, vim lub xeev tau saib xyuas kev tiv thaiv ib puag ncig thiab kev tswj hwm nruj dua ntawm cov tuam txhab muaj kuab paug siab, "peb cov khoom pov tseg" ua rau cov kav dej kub-dip galvanized yog qhov nyuaj los daws, ua ke nrog kev loj hlob sai ntawm stainless. steel welded kav, PVC cov kav dej thiab cov kav dej sib xyaw, nrog rau kev txhawb nqa cov khoom siv tshuaj hauv tsev thiab kev txwv tsis pub siv cov kav dej galvanized steel, kev txhim kho kub-dip galvanized welded yeeb nkab tau zoo heev txwv thiab txwv, thiab kev loj hlob ntawm kub. -dip galvanized welded yeeb nkab tau qeeb.
Cold galvanized steel yeeb nkab
Zinc txheej yog txheej txheej electroplating, uas yog cais los ntawm cov yeeb nkab steel matrix.Cov zinc txheej yog nyias, thiab cov zinc txheej tsuas yog txuas nrog cov yeeb nkab steel matrix, uas yooj yim rau poob.Yog li ntawd, nws cov corrosion kuj tsis zoo.Hauv cov tsev tshiab, nws yog txwv tsis pub siv cov kav dej txias galvanized steel li cov kav dej.
