Qhov sib txawv ntawm cov txheej txheem ntau lawm
Galvanized sawb yeeb nkab (pre galvanized steel yeeb nkab) yog ib hom welded yeeb nkab ua los ntawm vuam nrog galvanized steel sawb raws li raw khoom. Cov hlau sawb nws tus kheej yog coated nrog ib txheej ntawm zinc ua ntej dov, thiab tom qab welding rau hauv cov yeeb nkab, qee qhov kev tiv thaiv xeb (xws li zinc txheej lossis tshuaj tsuag xim) tsuas yog ua tiav.
Kub galvanized yeeb nkabyog ib tug welded dub yeeb nkab (zoo tib yam welded yeeb nkab) raws li ib tug tag nrho immersed nyob rau hauv ob peb puas degrees ntawm high-temperature zinc kua, thiaj li hais tias ob sab hauv thiab sab nrauv ntawm cov yeeb nkab steel yog uniformly qhwv nrog ib tug tuab txheej ntawm zinc. Cov txheej zinc no tsis tsuas yog sib txuas ruaj khov, tab sis kuj tsim cov yeeb yaj kiab tiv thaiv, tiv thaiv corrosion zoo.
Qhov zoo thiab qhov tsis zoo ntawm ob qho tib si
Galvanized sawb steel yeeb nkab:
Qhov zoo:
Tus nqi qis dua, pheej yig dua
Smooth nto, zoo dua tsos
Haum rau lub sijhawm uas tsis muaj kev tiv thaiv corrosion siab dhau
Qhov tsis zoo:
Tsis zoo corrosion kuj nyob rau hauv welded qhov chaw
Nyias zinc txheej, yooj yim rau xeb hauv kev siv sab nraum zoov
Lub neej luv luv, feem ntau 3-5 xyoos yuav muaj teeb meem xeb
Kub-dip galvanized steel yeeb nkab:
Qhov zoo:
Txheej zinc txheej
Muaj zog tiv thaiv corrosion kev ua tau zoo, haum rau sab nraum zoov lossis qhov chaw ntub dej
Lub neej ua haujlwm ntev, mus txog 10-30 xyoo ntau yam
Qhov tsis zoo:
Tus nqi siab dua
Me ntsis ntxhib nto
Welded seams thiab interfaces xav tau kev saib xyuas ntxiv rau kev tiv thaiv corrosion
