Galvanized steel kav muab faib ua kub dip galvanized thiab txias galvanized.
Kub-dip galvanizing yog cov txheej txheem ntawm immersing cov raj hauv qhov kub-kub zinc da dej kom tso cai rau zinc nkag mus rau hauv cov hlau nto. Qhov saum npoo ntawm cov yeeb nkab muaj cov txheej zinc tuab dua, thiab nws cov corrosion kuj yog siab tshaj qhov txias-dip galvanizing. Ntawm chav kawm, tus nqi kuj siab dua li txias dip zinc. Qhov tseeb, txias dip galvanizing yog cov yeeb nkab electro-galvanized. Cov zinc txheej adheres rau saum npoo ntawm cov yeeb nkab los ntawm cov tshuaj tiv thaiv electroplating, tab sis cov zinc txheej yog nyias thiab yooj yim tev tawm. pheej yig tus nqi. Ob tus nqi siab dua li cov kav hlau zoo tib yam. Tom qab tshwj xeeb txau rau ntawm qhov chaw ntawm cov kav dej galvanized, nws cov kev tiv thaiv corrosion yog kaum ob lub sij hawm siab dua li cov kav hlau hlau.
Qhov txawv ntawm galvanized steel yeeb nkab thiab zoo tib yam kauv steel yeeb nkab
Ordinary steel kav muaj kev tiv thaiv corrosion tsis zoo dua li cov kav hlau galvanized. Galvanizing yog hais txog galvanizing saum npoo ntawm cov kav dej steel. Nws tuaj yeem yog welded yeeb nkab lossis seamless yeeb nkab. Seamless hais txog cov txheej txheem tsim cov kav hlau nrog cov welds thiab tsis muaj cov ntsiab lus seam. Galvanized kav yog corrosion-resistant, seamless kav yuav tiv taus siab dua, thiab galvanized steel kav yuav tsis tshua muaj xeb vim kev tiv thaiv ntawm zinc. Galvanized yeeb nkab yog sib dua li seamless yeeb nkab. Yog tias siv lub sam thiaj, nws yog qhov zoo tshaj plaws los siv cov kav dej galvanized. Seamless steel kav tsis haum rau balconies. Vim yog cov phab ntsa loj ntawm cov kav dej seamless steel, lawv ib txwm hnyav thiab tus nqi ntawm cov kav dej seamless yog siab dua li cov kav dej galvanized. Cov kav dej Galvanized yog cov kav ntev heev thiab muaj kev pabcuam lub neej ntev dua li cov kav dej seamless. Yog tias qhov khoom zoo dhau lawm, nws yuav tsum tsis txhob muaj teeb meem rau ntau tshaj 20 xyoo. Tau kawg, qhov vuam thiab pleev xim yuav tsum ua kom zoo thiab yuav tsis cuam tshuam rau lub neej kev pabcuam ntawm cov yeeb nkab steel galvanized.
Qhov sib txawv tseem ceeb ntawm galvanized steel kav thiab cov kav hlau zoo tib yam yog:
1. Cov txheej txheem tsim khoom: Galvanized steel kav thiab cov kav hlau zoo tib yam yog ob pawg loj ntawm cov kav hlau. Galvanizing txhais tau hais tias qhov saum npoo ntawm cov yeeb nkab steel yog galvanized, thaum cov kav hlau zoo tib yam tsis yog.
2. Siv: Galvanized steel kav feem ntau yog siv los ua cov laj kab, laj kab, guardrails, thiab lwm yam. Siv dav hauv cov phiaj xwm hauv nroog, txoj kev, factories, tsev kawm ntawv, thaj chaw loj hlob, vaj, squares, thaj chaw nyob thiab lwm qhov chaw. Niaj hnub no, cov kav hlau zoo tib yam tau hloov pauv los ntawm cov kav hlau galvanized.
3. Durability: Galvanized kav yog ntau corrosion-resistant, thiab zoo tib yam hlau yuav tiv taus siab dua. Vim muaj kev tiv thaiv ntawm zinc, galvanized steel kav tsis yooj yim rau xeb thiab sib zog dua li cov kav hlau zoo tib yam.
