Galvanized steel kav tau muab faib ua ob hom: kub-dip galvanized steel yeeb nkab thiab txias-galvanized steel yeeb nkab. Cold-galvanized steel yeeb nkab, tseem hu ua electro-galvanized steel yeeb nkab, muaj cov ntsiab lus zinc tsawg, kwv yees li 10g txog 20g ib square meter, uas ua rau muaj kev tiv thaiv corrosion tsis zoo piv rau kub-dip galvanized steel yeeb nkab. Lub tom kawg boasts superior corrosion kuj. Tsis tas li ntawd, qhov sib txawv ntawm ob yog dab tsi?
Qhov sib txawv ntawm Kub-dip thiab Cold-galvanized Steel Pipes
Ua ntej, lawv txawv heev nyob rau hauv lawv cov txheej txheem ntau lawm. Cov zinc siv nyob rau hauv kub-dip galvanizing yog tau ntawm ib tug kub ntawm 450 degree mus rau 480 degree, whereas zinc nyob rau hauv txias-galvanized steel kav yog siv los ntawm ib tug electroplating txheej txheem ntawm chav tsev kub.
Qhov thib ob, muaj qhov sib txawv ntawm qhov tuab ntawm zinc txheej. Kub-dip galvanized steel kav muaj cov zinc txheej tuab dua li cov txias-galvanized.
Thib peb, lawv txawv ntawm qhov smoothness. Qhov saum npoo ntawm cov kav dej txias-galvanized steel yog qhov hnyav dua li cov kav dej kub-dip galvanized.
Plaub, muaj tus nqi sib txawv heev. Cov neeg tsim khoom feem ntau tsis txhob siv electroplating rau cov kav dej kub-dip galvanized kom zoo. Hauv qhov sib piv, cov lag luam me nrog cov cuab yeej siv tsis tu ncua feem ntau siv rau electroplating, ua cov kav dej txias-galvanized steel tsis tshua kim.
Thib tsib, cov kav dej kub-dip galvanized yog coated nrog zinc, hos cov kav dej txias-galvanized tsuas yog coated ntawm ib sab.
Thib rau, lawv cov khoom adhesion yog txawv. Cov kav dej txias-galvanized nthuav tawm cov adhesion tsis zoo piv rau cov kav dej kub-dip galvanized vim nyias thiab yooj yim detachable zinc txheej, uas tsuas yog txuas rau cov hlau substrate ntawm nws tus kheej.
Cov kav dej txias-galvanized undergo electroplating, ua rau zinc txheej tsuas yog nyob rau sab nrauv, tsis yog phab ntsa sab hauv. Nyob rau hauv sib piv, kub-dip galvanized kav dej kub-dip galvanizing, kom ntseeg tau zinc txheej ntawm ob sab hauv thiab sab nrauv phab ntsa. Cov kev cai txwv tsis pub siv cov kav dej txias-galvanized rau cov kav dej thiab cov kav dej vim lawv cov corrosion tsis zoo, zinc tev tau yooj yim, thiab muaj peev xwm muaj kev nyab xeeb.
Hauv cov ntsiab lus, qhov sib txawv tseem ceeb nyob hauv zinc thickness, nto smoothness, nqi, corrosion kuj, thiab adhesion zog.
