Q: Yuav ua li cas los tiv thaiv- kev kho corrosion ntawm Q235 steel?
A: Rau qhov chaw nyob sab hauv tsev qhuav, lub tsho nyias nyias yog txaus; rau sab nraum zoov / ntub dej / ntug hiav txwv dej, yuav tsum tau ua cov kauj ruam nram qab no: tshem tawm xeb → primer → intermediate coat → topcoat; los yog kub-dip galvanizing, los yog kev tiv thaiv sib xyaw ntawm galvanizing thiab txheej.
Q: Dab tsi yog qhov kev tiv thaiv hluav taws kub rau Q235 steel qauv?
A: Siv hluav taws kub- cov txheej txheej retardant (nyias / tuab), qhwv nrog cov ntaub thaiv hluav taws, los yog qhwv hauv cov pob zeb kom ntseeg tau tias qhov hluav taws kub tiv thaiv tau raws li cov qauv tsim (xws li 2.5h rau txhua kab, 1.5h rau kab teeb).
Q: Dab tsi yog hom tsis ua haujlwm ntawm Q235 steel thaum siv? Yuav ua li cas zam lawv?
A: Cov qauv tsis ua haujlwm feem ntau suav nrog cov yas deformation, tawg tawg, corrosion, thiab qaug zog tsis ua haujlwm. Kev Tiv Thaiv: Xaiv cov khoom siv thiab tsim raws li cov lus qhia tshwj xeeb, tswj hwm kev tsim kho kom zoo, ua raws li kev tiv thaiv kev tiv thaiv - kev tiv thaiv corrosion thiab hluav taws kub, thiab ua haujlwm tsis tu ncua.
Q: Q235 steel puas tuaj yeem siv nyob rau hauv ntug dej hiav txwv lossis chaw muaj tshuaj lom neeg?
A: Yog lawm, tab sis txhim kho kev tiv thaiv kev tiv thaiv kev tiv thaiv yog tsim nyog (piv txwv li, hnyav- lub luag haujlwm tiv thaiv - xeb txheej, kub- dip galvanizing + sealing xim), thiab yuav tsum tau kuaj xyuas thiab tu tsis tu ncua; txwv tsis pub, nws yooj yim rau xeb.
Q: Dab tsi yog qhov tsim qauv kev pabcuam lub neej ntawm Q235 steel qauv?
A: Raws li kev saib xyuas ib txwm, lub neej ua haujlwm feem ntau yog 50 xyoo rau cov tsev; 5-10 xyoo rau cov qauv ib ntus; nyob rau hauv corrosive ib puag ncig, lub neej kev pab cuam yuav tsum tau luv luv los yog kev tiv thaiv upgraded.
