Nrog rau kev vam meej tas mus li ntawm tib neeg, hom kev ua liaj ua teb ib txwm muaj tsis tuaj yeem ua tau raws li cov kev xav tau ntawm txoj kev loj hlob ntawm kev vam meej niaj hnub no, thiab kev ua liaj ua teb tshiab yog nrhiav tom qab cov neeg hauv kev lag luam. Qhov tseeb, cov khoom siv ua liaj ua teb feem ntau yog cov tsev cog khoom. Nws tsis txwv los ntawm lub sijhawm thiab qhov chaw. Nws tuaj yeem nqa tawm kev ua liaj ua teb hauv thaj chaw tshwj xeeb xws li toj siab, roob tob thiab suab puam. Raws li lub hauv paus ntawm qhov project tsev cog khoom, cov ntaub ntawv yuav tsum tswj qhov project zoo, ua ntej ntawm tag nrho cov, los ntawm kev xaiv cov ntaub ntawv. Piv txwv li, rau cov khoom siv hlau siv hauv qhov project tsev cog khoom, cov hlau zoo yuav raug ua tiav thiab derusted. Tom qab kub plating nyob rau hauv ib tug kws galvanizing nroj tsuag, lub chaw soj ntsuam zoo yuav sim nws dua. Tom qab dhau qhov kev xeem, nws yuav raug thauj mus rau qhov chaw tsim khoom siv.

1. Kub dip galvanized steel yeeb nkab qauv: kub dip galvanized yeeb nkab yog ua kom molten hlau react nrog hlau matrix los tsim alloy txheej, thiaj li ua ke cov matrix thiab txheej. Kub-dip galvanized yeeb nkab muab los ntawm Tianjin Feilong Pipe Co., Ltd. yog thawj zaug pickled. Txhawm rau tshem tawm cov hlau oxide nyob rau saum npoo ntawm cov yeeb nkab steel, tom qab pickling, nws yog ntxuav nyob rau hauv ammonium chloride los yog zinc chloride aqueous tov los yog ammonium chloride thiab zinc chloride tov aqueous tov tank, thiab ces xa mus rau lub kub-dip galvanizing tank. Kub dip galvanizing muaj qhov zoo ntawm txheej txheej, muaj zog adhesion thiab lub neej ua haujlwm ntev. Lub matrix ntawm kub-dip galvanized steel yeeb nkab muaj complex lub cev thiab tshuaj lom neeg cov tshuaj tiv thaiv nrog molten plating tov los tsim ib tug corrosion-resistant zinc ferroalloy txheej nrog compact qauv. Lub alloy txheej yog kev sib xyaw nrog cov ntshiab zinc txheej thiab cov yeeb nkab steel matrix. Yog li ntawd, nws muaj zog corrosion kuj.

2. Galvanized sawb yeeb nkab qauv: galvanized sawb yeeb nkab kho cov txheej txheem ntawm kub-dip galvanized yeeb nkab. Ua ntej, cov sawb hlau siv los ua cov yeeb nkab yuav tsum tau muab tshem tawm kom tshem tawm cov hlau oxide ntawm qhov chaw ntawm cov hlua hlau. Tom qab ntawd cua qhuav thiab ua ib lub yeeb nkab. Cov txheej txheej yog sib xws thiab ci, thiab cov nyiaj zinc plating yog me me, uas yog qis dua tus nqi ntawm kev tsim cov yeeb nkab kub-dip galvanized. Nws cov corrosion kuj yog me ntsis phem dua li ntawm kub-dip galvanized yeeb nkab
