Cov Hlau Galvanized Hlau Yuav Siv Tau Ntev Npaum Li Cas? Cov Yam Tseem Ceeb thiab Phau Ntawv Qhia Txog Khoom

Lub neej ntawmhlau galvanizedNws txawv ntau heev. Nws feem ntau nyob ntawm cov txheej txheem galvanizing thiab ib puag ncig uas nws siv. Cov hlau galvanized Suav zoo, tshwj xeeb tshaj yog cov hlau kub-dipped galvanized nrog cov txheej zinc tuab (50 - 150μm), muaj kev tiv thaiv corrosion zoo. Hauv thaj chaw qhuav hauv av, nws tuaj yeem kav ntev li 10 txog 45 xyoo. Hauv thaj chaw noo noo lossis ntug dej hiav txwv, nws tuaj yeem kav ntev li 2 txog 15 xyoo. Ntawm qhov tod tes, cov hlau galvanized ib txwm tsuas yog ua haujlwm tau 3 txog 8 xyoo hauv ib puag ncig ib txwm.
Rau kev siv sib txawv,GI hlau 18 gaugeyog nrov vim nws yoog tau. Nws zoo rau kev khi thiab ua laj kab. Sab nraum zoov, nws tuaj yeem kav ntev li 5 txog 12 xyoos. 4 hli hlau hlau thiab 6 hli GI hlau feem ntau siv rau hauv kev tsim kho thiab kev ua liaj ua teb vim lawv muaj lub zog tensile siab. Hauv cov xwm txheej qhuav, lawv tuaj yeem kav ntev dua 15 xyoos. Thaum koj saib cov nqi ntawm 6 hli thiab 4 hli GI hlau, koj yuav pom tias cov khoom kub - dipped kim dua me ntsis, tab sis lawv pheej yig - zoo rau lub sijhawm ntev. Lawv lub zog txhais tau tias koj tsis tas yuav hloov lawv ntau zaus.

Yuav kom cov hlau kav ntev li ntev tau, tsis txhob cia cov txheej zinc puas tsuaj los ntawm kev siv tshuab. Thiab xaiv hom zoo rau ib puag ncig. Txawm koj siv nws hauv kev lag luam lossis hauv tsev, cov khoom siv hlau galvanized Suav teb zoo likub dipped galvanized hlau xaimua tau zoo. Lawv lub neej siv tau zoo sib xws nrog qhov zoo thiab koj siv lawv li cas.
