1.What yog cov kev sib tw tseem ceeb ntawm kev siab tshaj plaws thiab txias ib puag ncig?
Huab tsis tshua muaj kub: tus brittleness ntawm zinc txheej nce, thiab cov ductures-brittle transition kub ntawm substrate steel nce.
Freeze-thaw Chople: Ice Crystal nthuav tawm cov txheej txheej → microcacks nthuav dav → substrate yog nthuav tawm.
Muaj zog ultraviolet teeb: nrawm nrawm qhov kev laus ntawm cov organic txheej thiab txhim kho cov ntawv khawv koob ntawm cov duabsoxidation ntawm zinc txheej.
Cov pa oxygen qis: cathergen txo cov tshuaj tiv thaiv yog dab tsi, thiab kev txi anode tiv thaiv kev txuag.
Hnub thiab hmo ntuj kub qhov sib txawv: Kev ntxhov siab sov ua rau cov txheej txheej / substrate interface rau tev tawm.
2.Qhov kev hloov pauv tau tshwm sim hauv cov ntaub ntawv ua tau zoo?
Cov Khoom Siv Neeg Kho Tshuab Lwj
Corrosion tus nqi sib piv: Corrosion tus nqi hauv cov chaw dej hiav txwv muaj thaj av yog 15-25; Corrosion tus nqi hauv thaj chaw txias txias yog 8-12 xyoos
3.Qhov yog tus tseem ceeb tiv thaiv thev naus laus zis?
Nano-saled txheej: sio₂ sol (particle loj 20nm) yog dip vapor channel →
Thaum tshav kub kub-Reflective Topcoat: Rutile tioul (restities> 8% li alloy) yog siv, thiab tseem muaj kev tiv thaiv tam sim no AT -50 degree.
4.Qhov twg yog qhov kev thov siv tau cov xwm txheej?
Kev Sib Kis Ntauwd
Khoom siv: S420mc + ni microalloying
Cov Txheej: ZN-5% al-mg-CE + Epoxy Micraceous Hlau Xim
Photovoltaic bracket
Txheej Txheej Txheem: ZM Txheej (150g / M²) + Cov Fluorocarbon Txheej (PVDF)
Tus Qauv Tsim: Loj dua los yog sib npaug rau 40℃kom txo cov npog daus
Cov Saib Xyuas Tsheb
Connector: Siv ZN-al-Mg coated Nylon bushing los thaiv txias brittle transtection
5.Qhov caj ces tsis sib haum ntawm galvanized steel nyob rau hauv high-altions fittly thiab khov-thau lub cev puas tsuaj, es tsis yooj yim tshuaj lom neeg corrosion. Cov hau kev twg yuav siv tau los txhim kho qhov yoog tau rau ib puag ncig zoo heev?
Matrix ua kom tawv (ntxiv NI / CE)
Nano-txheej (ZN-AL-MG-CE LIS COMPININEMENT)
Txheej Txheej Txheej Txhim Kho Kom Zoo (Nano-Sealing + Fluorocarbon Thij)
