Galvanized steel kav yog dav siv, tsis tsuas yog nyob rau hauv kev tsim khoom ntawm kev ua hauj lwm, tab sis kuj nyob rau hauv lub chaw tsim khoom ntawm machinery, thiab lwm yam, uas yuav piav raws li ntau yam thiab nyob rau hauv ib tug ntau yam ntawm teb.Thaum muas galvanized steel kav, ntau tus neeg siv khoom txaus siab rau kev siv cov kav hlau galvanized.Tsis tas li ntawd, lawv tsis paub ntau txog hom galvanized steel kav.Niaj hnub no peb yuav kawm ntxiv txog lawv..
Dab tsi yog kev siv galvanized steel yeeb nkab?
1. Muaj ob hom galvanized steel kav: kub-dip galvanizing thiab hluav taws xob galvanizing.Kub-dip galvanizing muaj ib txheej tuab galvanized, uas muaj qhov zoo ntawm cov txheej txheej, muaj zog adhesion, thiab kev pab lub neej ntev.Tus nqi ntawm electro-galvanizing yog tsawg, qhov saum npoo tsis du heev, thiab nws cov corrosion kuj yog qhov phem dua li cov kav dej kub-dip galvanized.
2. Kev siv cov kav dej galvanized: cov kav hlau uas siv rau cov roj thiab cua sov kuj yog cov kav dej galvanized.Galvanized kav yog siv los ua cov kav dej.Cov kab mob uas loj hlob ntawm cov phab ntsa sab hauv ntxhib thiab xeb ua rau cov hlau hnyav hnyav hauv dej, uas ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv.Nyob rau xyoo 1960 thiab 1970, cov teb chaws tsim kho hauv ntiaj teb tau pib tsim cov kav dej tshiab thiab maj mam txwv cov kav dej galvanized.Plaub lub tuam tsev thiab cov thawj coj suav nrog Ministry of Construction ntawm Tuam Tshoj kuj tau tshaj tawm cov ntaub ntawv hais tias cov kav dej galvanized yuav raug txwv los ntawm 2000, thiab ntau cov kav dej galvanized uas tau siv ua ntej tseem tuaj yeem pom niaj hnub no.Tam sim no, cov kav dej galvanized tsis tshua muaj siv hauv cov kav dej txias hauv cov zej zog uas tau tsim tshiab, thiab cov kav dej galvanized tau siv hauv cov kav dej kub hauv qee cov zej zog.
3. Galvanized muaj zog tiv thaiv zoo thiab muaj zog corrosion kuj.Tag nrho cov qauv yog tsim los ntawm zinc, tsim ib tug ntom quaternary siv lead ua, uas tsim ib tug barrier ntawm steel phaj, yog li zoo tiv thaiv kev nkag mus ntawm corrosion yam.Kev tiv thaiv corrosion los ntawm kev tiv thaiv muaj zog ntawm cov txheej txheem ntawm zinc.Thaum zinc siv rau kev tiv thaiv kev txi ntawm cov npoo txiav, khawb thiab khawb ntawm cov txheej, zinc tsim cov txheej txheem oxide insoluble los ua kev tiv thaiv kev tiv thaiv.
Dab tsi yog hom galvanized steel kav?
1. Kub-dip galvanized square raj: Nws yog ib lub raj square ua los ntawm vuam steel daim hlau los yog steel strips tom qab crimping thiab sib sau.Nyob rau hauv lub hauv paus ntawm lub square tube, lub square raj yog muab tso rau hauv ib tug kub-dip galvanizing pas dej ua ke kom undergo ib tug series ntawm tshuaj tshua.Tom qab ntawd tsim ib lub raj square.Cov txheej txheem ntau lawm ntawm kub-dip galvanized square raj yog qhov yooj yim, thiab cov khoom siv tau zoo heev, thiab muaj ntau ntau yam thiab specifications.Hom square tube no xav tau cov cuab yeej siv me me thiab peev, thiab tsim nyog rau kev tsim cov khoom me me galvanized square raj manufacturers.Tab sis nyob rau hauv cov nqe lus ntawm lub zog, lub zog ntawm no hom ntawm steel yeeb nkab yog tsawg tshaj li ntawm seamless square yeeb nkab.
2. Lub raj txias galvanized square raj siv lub hauv paus ntsiab lus ntawm txias galvanizing ntawm lub raj square siv los ua cov square raj los tiv thaiv corrosion.Sib txawv ntawm kub-dip galvanizing, txias-dip galvanizing tsuas yog siv cov txheej txheem electrochemical los tiv thaiv corrosion.Yog li ntawd, nws yog ib qho tsim nyog kom muaj kev sib cuag txaus ntawm zinc hmoov thiab hlau los tsim cov electrode muaj peev xwm sib txawv.Yog li ntawd, kev kho saum npoo ntawm cov hlau tseem ceeb heev.
Hom thiab specifications ntawm galvanized steel kav xaiv nyob rau hauv txawv cheeb tsam yog txawv.Thaum yuav khoom, koj tuaj yeem xaiv raws li koj tus kheej xav tau.Ua tib zoo xaiv cov kav hlau uas muaj npe.Cov saum toj no yog cov lus qhia txog kev siv cov kav hlau galvanized thiab dab tsi yog hom galvanized steel kav.
