1.Txoj cov ntug dej hiav txwv, cov txheej txheem txheej thiab kev tiv thaiv cov khoom ntawm kub-dip galvanized kav?
Cov txheej kub ntawm cov kav dej kub galvanized yog tsim los ntawm cov tshuaj tiv thaiv kev kub thiab yog tsim los ntawm ib txheej zinc (sab hauv txheej zinc Tus qauv no tso cai rau txheej kom nruj nreem rau cov yeeb nkab steel substrate, tsim cov txheej txheem tiv thaiv txheej txheem. Txawm hais tias nws yog ib nrab puas, cov txheej zinc tseem txuas ntxiv tiv thaiv lub substrate los ntawm corroding nws tus kheej ua ntej los ntawm lub ntsiab cai ntawm kev tiv thaiv Cathodic. Ntawm qhov tod tes, lub electro-galvanized yeeb nkab cov txheej dawb paug los ntawm kev tso nyiaj electrolytic, thiab tsuas yog sib khi mus rau lub substrate los ntawm kev kos duab lub cev. Thaum cov tshuab kev ntxhov siab lossis nruab nrab ntawm nruab nrab, txheej yog nquag mus rau teeling, ua rau muaj kev ua yeeb yam, thiab kev tiv thaiv tsis muaj zog.
2. Siv cov ntug dej hiav txwv, dab tsi yog cov txheej tuab thiab corrosion tsis kam ntawm kub-dip galvanized kav?
Lub thickness ntawm kub-dip galvanized txheej feem ntau yog tuab dua li cov electro-galvanized txheej. Feem ntau, cov tuab ntawm cov kub-dip galvanized txheej yog loj dua los yog sib npaug rau 55μm. Nyob rau hauv nruab nrab ntsev tsuag, nws tuaj yeem mus txog ntau dua 1000 teev, thiab lub luag haujlwm-anti-corrosion txheej tuaj yeem tseem tshaj 5000 teev. Lub thickness ntawm electro-galvanized txheej feem ntau {{9} μm. Yog tsis muaj kev kho mob passivation, kev kuaj ntsev tsuas yog 24-36 sijhawm. Tom qab xiav-dawb passiveation, nws tuaj yeem nce mus txog 72 teev, uas yog qhov qis dua qhov kub-dip galvanized flavanized. Nyob rau hauv lub vaum huab cua hauv ntug hiav txwv, cov tuab tuab ntawm cov kav dej kub uas muaj peev xwm muab kev tiv thaiv thiab muaj zog dua rau corrosion.
3.Qhov yog ib puag ncig kev hloov kho ntawm kub-dip galvanized cov kav dej hauv ntug hiav txwv?
Kub-DIP galvanized kav yog haum rau cov chaw hnyav xws li cov av noo, cov ntsev ntau, kua qaub thiab alkali. Hauv cov av nrog tus nqi pH ntawm 4-10, cov xeb yog tsuas {2}}. 001mm \/ xyoo. Cov huab cua hauv cov ntug hiav txwv yog noo thiab muaj ntsev. Kub-DIP galvanized kav dej tuaj yeem hloov kho rau qhov ib puag ncig no zoo dua thiab ua kom muaj kev phom sij ntawm cov dej qias thiab cov ntsev tsuag. Nyob rau hauv kev sib piv, electro-galvanized kav yog cov haum rau cov chaw pw hauv tsev. Nyob rau hauv ib puag ncig nrog vertity> 60% lossis muaj chloride ions, lawv tus nqi corrosion, lawv yuav nce ntxiv, thiab lawv muaj peev xwm ua kom muaj teeb meem tas li, siv hauv cov ntug hiav txwv.
4.What yog tus saib xyuas tus nqi ntawm kub-dip galvanized kav dej hauv ntug hiav txwv?
Kub-DIP galvanized kav ntev muaj lub sijhawm tu ntev, thiab tus txij nkawm nyob rau hauv ib {xyoo yog tsuas yog 1\/3 ntawm cov kav hluav taws xob hluav taws xob. Vim tias nws zoo corrosion tsis kam, nws tsis xav tau kuaj nquag thiab kho thaum siv hauv cov ntug dej hiav txwv. Electro-galvanized kav, ntawm qhov tod tes, yuav tsum tau tshuaj xyuas ib txwm. Thaum kev puas tsuaj rau txheej yog pom, nws yuav tsum tau kho nyob rau lub sijhawm nrog Zinc-nplua nuj xim, thiab lwm yam, xeb yuav kis tau sai, nce cov nqi kho mob thiab cov haujlwm.
5.Qhov yog kev lag luam qauv ntawm kub-dip galvanized cov yeeb nkab?
Kub-DIP galvanizing yog txuas ntxiv txhim kho corrosion tsis kam los ntawm chromium hloov txheej), thiab cov tshuaj ntsev ua kom ncav cuag ntau dua 2000 teev.
