Taw qhia
Galvanized steel yog cov khoom siv nrov siv hauv kev tsim kho, tsheb, thiab kev lag luam vim nws cov kav ntev thiab tsis kam xeb thiab xeb. Nws yog tsim los ntawm txheej hlau nrog ib txheej ntawm zinc los tiv thaiv nws ntawm cov khoom. Txawm li cas los xij, txawm tias nws cov txiaj ntsig ntau, galvanized steel kuj muaj qee qhov tsis zoo.
Hauv tsab xov xwm no, peb yuav tshawb txog qhov tsis zoo ntawm cov hlau galvanized hauv qhov tob, suav nrog nws cov kev pheej hmoo kev noj qab haus huv, kev cuam tshuam ib puag ncig, thiab kev txwv hauv qee yam kev siv.
Kev Nyab Xeeb Kev Nyab Xeeb
Ib qho ntawm qhov tsis zoo ntawm cov hlau galvanized yog nws cov kev pheej hmoo rau kev noj qab haus huv. Zinc yog cov hlau uas muaj tshuaj lom uas tuaj yeem ua rau muaj ntau yam teeb meem kev noj qab haus huv yog tias noj lossis nqus tau. Thaum galvanized steel raug txiav, drilled, los yog welded, nws muaj peev xwm tso zinc fumes thiab hmoov av mus rau hauv cov huab cua. Yog tias nqus tau, cov khoom no tuaj yeem ua rau muaj teeb meem ua pa, nrog rau ua tsis taus pa, hnoos, thiab hawb pob.
Tsis tas li ntawd, cov neeg ua haujlwm uas tuav cov hlau galvanized tsis tu ncua kuj tseem yuav muaj kev pheej hmoo ntawm kev tsim cov zinc lom. Cov tsos mob ntawm zinc lom muaj xws li xeev siab, ntuav, raws plab, thiab mob taub hau, thiab tuaj yeem ua rau mob hnyav dua yog tias tsis kho sai. Yog li ntawd, nws yog ib qho tseem ceeb rau cov neeg ua haujlwm yuav tsum tau ceev faj txog kev nyab xeeb thaum tuav cov khoom siv hlau galvanized, xws li hnav cov iav tiv thaiv zoo li lub tshuab ua pa thiab hnab looj tes.
Kev cuam tshuam ib puag ncig
Lwm qhov downside ntawm galvanized steel yog nws ib puag ncig cuam tshuam. Kev tsim khoom thiab pov tseg ntawm cov hlau galvanized tuaj yeem muaj kev cuam tshuam tsis zoo rau ib puag ncig, tshwj xeeb ntawm kev siv hluav taws xob thiab kev tswj cov khib nyiab.
Cov txheej txheem ntawm galvanizing hlau yuav tsum muaj lub zog tseem ceeb, feem ntau nyob rau hauv daim ntawv ntawm hluav taws xob thiab cov nkev roj. Qhov kev siv hluav taws xob no ua rau lub tsev xog paj emissions thiab kev hloov pauv huab cua. Tsis tas li ntawd, galvanizing steel kuj tsim cov khoom pov tseg, xws li siv cov kua qaub thiab cov slag, uas tuaj yeem nyuaj rau pov tseg kom zoo. Cov khoom pov tseg no tuaj yeem muaj cov khoom phom sij thiab tuaj yeem ua rau cov av thiab dej hauv av yog tias tsis tswj kom raug.
Kev txwv hauv qee yam kev siv
Galvanized steel kuj muaj kev txwv hauv qee yam kev siv. Thaum nws muaj kev ruaj khov thiab tiv taus corrosion, nws yuav tsis haum rau qee qhov chaw lossis tej yam kev mob. Piv txwv li, galvanized steel tej zaum yuav corrode sai dua nyob rau hauv acidic los yog alkaline ib puag ncig, uas yuav muaj ntau nyob rau hauv industrial chaw. Nws kuj tseem yuav ua haujlwm tsawg dua hauv thaj chaw uas muaj cov av noo siab lossis dej ntsev, xws li thaj chaw ntug dej hiav txwv.
Tsis tas li ntawd, galvanized steel tej zaum yuav tsis yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau qib siab ntawm precision lossis zoo nkauj. Cov txheej txheej ntawm zinc ntawm cov hlau tuaj yeem ua rau nws nyuaj rau kev ua tiav kev ua tiav lossis kev ntsuas raug, uas tuaj yeem yog qhov tseem ceeb hauv qee qhov kev tsim khoom lossis kev tsim kho.
Alternatives rau Galvanized Steel
Muab nws cov downsides, muaj ntau yam kev xaiv rau galvanized steel uas tsim nyog xav txog. Qee qhov kev xaiv no suav nrog:
- Stainless hlau: Stainless hlau yog cov khoom siv ruaj khov, tiv taus corrosion uas feem ntau siv hauv kev tsim kho, tsheb, thiab kev lag luam. Nws yog kim dua li cov hlau galvanized, tab sis nws yuav yog ib qho kev xaiv zoo dua rau cov ntawv thov uas xav tau qib siab ntawm kev tiv thaiv corrosion, acidity, los yog alkalinity.
- Painted steel: Painted steel yog lwm txoj kev rau galvanized steel. Nws suav nrog kev siv cov xim pleev xim rau saum npoo ntawm cov hlau, uas tuaj yeem pab tiv thaiv xeb thiab xeb. Txawm hais tias nws yuav tsis zoo li cov hlau galvanized, nws tuaj yeem raug nqi ntau dua rau qee yam kev siv.
- Aluminium: Aluminium yog lub teeb yuag, corrosion-resistant khoom uas feem ntau siv nyob rau hauv aerospace, automotive, thiab kev lag luam. Nws tuaj yeem yog lwm txoj hauv kev zoo rau galvanized steel hauv cov ntawv thov uas xav tau qib siab ntawm qhov tseeb lossis kev zoo nkauj, vim nws tuaj yeem ua tau yooj yim dua thiab ua kom zoo dua li cov hlau.
Xaus
Hauv kev xaus, thaum galvanized steel muaj ntau yam txiaj ntsig, nws kuj muaj ntau qhov tsis zoo uas yuav tsum tau xav txog. Cov no suav nrog kev pheej hmoo rau kev noj qab haus huv, kev cuam tshuam ib puag ncig, thiab kev txwv hauv qee yam kev siv. Los ntawm kev nkag siab txog cov kev tsis zoo no, peb tuaj yeem txiav txim siab paub ntau ntxiv txog thaum twg thiab qhov twg siv cov hlau galvanized, nrog rau xav txog lwm cov ntaub ntawv uas yuav zoo dua rau peb cov kev xav tau.
