Lawv kuj ua rau xeb thiab xeb thaum lub sijhawm, tshwj xeeb tshaj yog tias cov zinc txheej yog khawb lossis puas.

** Lub zog sib piv

Cov kav hlau feem ntau muaj zog dua li cov kav dej galvanized vim lawv cov phab ntsa tuab thiab muaj zog tensile ntau dua. Cov kav hlau cam khwb cia muaj lub zog tensile ntawm 40, 000 psi, thaum cov kav dej galvanized muaj lub zog tensile ntawm 38, 000 psi. Cov kav hlau kuj tuaj yeem tiv taus siab dua thiab hnyav dua li cov kav dej galvanized.

Thaum nws los txog rau corrosion kuj, ob qho tib si hlau thiab galvanized kav muaj lawv lub zog thiab tsis muaj zog. Cov kav hlau hlau tiv taus rau ntau hom kev xeb, tshwj tsis yog rau thaj tsam acidic thiab alkaline. Galvanized kav, ntawm qhov tod tes, yog cov resistant rau xeb thiab corrosion, tab sis lawv muaj peev xwm corrode yog raug rau acidic los yog alkaline ib puag ncig.

Nyob rau hauv cov nqe lus ntawm lifespan, ob qho tib si hlau thiab galvanized kav yuav kav ntev li ob peb xyoo lawm nrog kev tu thiab tu kom zoo.

Txawm li cas los xij, cov kav dej galvanized muaj ntau dua rau xeb thiab xeb thaum lub sijhawm, uas tuaj yeem ua rau lawv lub neej luv.

** Lus xaus

Hauv kev xaus, ob qho tib si hlau thiab galvanized kav muaj lawv qhov zoo thiab qhov tsis muaj zog. Cov kav hlau muaj zog dua, ruaj khov dua, thiab tiv taus corrosion ntau dua, tab sis lawv kuj hnyav dua, kim dua, thiab nyuaj rau nruab. Galvanized kav, ntawm qhov tod tes, yog lub teeb yuag, yooj yim rau nruab, thiab siv tau zoo, tab sis lawv tsis muaj zog thiab ntau dua rau xeb thiab xeb.

Thaum xaiv cov kav hlau thiab cov galvanized, nws yog ib qho tseem ceeb uas yuav tau xav txog cov ntawv thov tshwj xeeb, cov peev nyiaj, thiab kev saib xyuas yuav tsum tau ua. Rau cov kav dej hauv tsev thiab kev siv hnyav, cov kav dej hlau yuav yog qhov kev xaiv zoo dua. Txawm li cas los xij, rau kev siv sab nraum zoov thiab cov haujlwm me me, cov kav dej galvanized yuav tsim nyog dua.
