Yuav ua li cas xaiv cov kav dej zoo Galvanized

Piv rau cov kav hlau zoo tib yam, cov kav dej galvanized muaj kev ua tau zoo dua. Txawm li cas los xij, kuj tseem muaj qee qhov tsis zoo ntawm cov kav hlau galvanized ntawm kev ua lag luam uas dhau los ntawm qhov tsis zoo. Kev siv cov kav dej tsis zoo galvanized tuaj yeem muaj kev cuam tshuam loj rau qhov project. Yog li ntawd, thaum yuav cov kav dej galvanized, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas qhov zoo ntawm cov kav dej galvanized. Feem ntau, muaj ntau txoj hauv kev:
1. Saib lub ntsej muag
Cov kav dej zoo galvanized muaj qhov zoo nkauj, tsis muaj zinc nodules lossis burrs, thiab feem ntau yog nyiaj dawb hauv cov xim; Cov kav hlau tsis zoo galvanized tsis muaj hlau nplaum, pom lub teeb liab los yog xim zoo ib yam li npua hlau, thiab nws yuav ua rau burrs thiab khawb, nrog khawb tob kom txo tau lub zog ntawm cov hlau.
2. Qhov hnyav
High quality galvanized steel kav muaj tsawg impurities, muaj ib tug siab ceev, thiab muaj ib tug me me sib txawv. Qhov hnyav thiab kuaj xyuas lawv tuaj yeem txiav txim siab qhov zoo. Feem ntau, xav txog qhov ua yuam kev, nws raug nquahu kom siv tag nrho cov theem hnyav kom tau txais txiaj ntsig zoo dua.
3. Tshawb xyuas kev ua haujlwm
Cov kav dej zoo galvanized yog dawb los ntawm hydrogen embrittlement thiab kub txaus ntshai, kom ntseeg tau tias cov khoom tsis hloov pauv thiab zoo corrosion kuj. Qhov nruab nrab ntsev tshuaj tsuag mus txog 240, thiab qhov hnyav ntawm txheej galvanized yuav tsum tsis txhob tsawg dua 500g / ㎡; Vim yog cov khoom siv tsis zoo, cov kav dej tsis zoo galvanized feem ntau muaj cov nqaij tev thiab tsis sib xws ntawm lub ntsej muag txiav, thiab cov kab rov tav ntawm cov kav dej tsis zoo thiab cov kav dej tsis zoo yog nyias thiab qis, feem ntau ua rau tsis txaus.
4. Ua kev sim
Kev ntsuas sib xws thiab kev ntsuas txias txias tau ua rau ntawm cov kav dej galvanized, thiab cov qauv zoo galvanized steel yeeb nkab tau txuas ntxiv rau hauv cov tshuaj tooj liab sulfate rau 5 zaug yam tsis muaj xim liab; Galvanized steel kav nrog ib txoj kab uas hla tsis tshaj 50 hli yuav tsum tau mus rau ib tug txias dabtsi yog khoov xeem nrog ib tug dabtsi yog khoov lub kaum sab xis ntawm 90 degree.
