Cov FAQ
1. Dab tsi yog qhov kev ua haujlwm siab tshaj plaws?
Nws yog qhov haum rau kev ntsuas siab - Cov ntaub ntawv siv tsawg dua lossis sib npaug rau 350 degree. Tshaj li qhov kub no yuav ua rau cov khoom siv neeg kho tshuab thiab cuam tshuam kev nyab xeeb system.
2. Nws puas tuaj yeem thauj cov kua ntshav?
Cov khoom siv hauv paus muaj cov corrosion resistance. Kev thauj cov kua ntawm cov kua roj uas yuav tsum muaj cov tshuaj tiv thaiv ntxiv kom muaj kev kho mob corrosion (xws li epoxy txheej lossis galvanizing).
3. Kuv yuav xaiv cov phab ntsa tuab li cas?
Xaiv los ntawm kev ua haujlwm ntawm kev ua haujlwm: rau siab - qhov siab / siab {{1 corrosion cov ntawv thov, xaiv cov phab ntsa Corrosion (xws li Sche0); Rau qis - h siab / tsawg {- Corrosion cov ntawv thov, xaiv cov phab ntsa corrosion (xws li Schia). Thov nrog peb pab neeg ua haujlwm rau kev suav ua engineering.
4. Puas muaj ib qho tsis - tus qauv ntau thiab tsawg?
Peb txhawb kev cai siv ntau thiab tsawg. Thov muab koj cov KS D3562 cov yeeb nkab hlau sab nraud ntawm txoj taub, phab ntsa tuab, thiab ntev yuav tsum tau. Peb pab neeg muag yuav ntsuas qhov ua tau thiab muab cov lus sau.
5. Dab tsi yog lub sijhawm khoom xa tuaj?
Rau cov qauv kev qhia tshwj xeeb, cov hmoov txhuas yog 15 - 30 hnub. Rau cov qauv tsis yog txheej txheem / loj xaj, kev hloov kho tau ua raws li cov caij nyoog tsim khoom. Lub sijhawm xa tawm tshwj xeeb tuaj yeem paub tseeb thaum tso kev txiav txim.
