Anti-corrosion kho txheej txheem ntawm lub suab barrier kem:
1. Kev tshem tawm xeb thiab tiv thaiv kev kho mob ntawm cov suab nrov barrier kab thiab cov ntxaij vab tshaus yuav tsum ua tau raws li cov qauv tsim thiab cov kev cai cuam tshuam, thiab yuav tsum ua raws li cov kev cai ntawm "Technical Conditions for Anticorrosion of Steel Structures for Expressway Traffic Engineering" (GB /T18226).2.Ua ntej nkag mus rau kub-dip galvanizing ntawm lub suab barrier tus tswv cuab, cov tswv cuab yuav tsum tau electrolytically pickled kom lub hauv paus hlau nto huv si.3.Cov txheej txheem steel ntawm cov suab nrov yuav tsum yog qhov chaw tiv thaiv corrosion los ntawm kub-dip galvanizing thiab yas txau tom qab galvanizing.4.Kev kho kub-dip galvanizing: zinc siv rau kub-dip galvanizing yuav tsum tsis txhob qis dua qhov tshwj xeeb No.1 thiab No.1 zinc ingot teev hauv "Zinc Ingot" (GB / T470).
Plating tus nqi ntawm zinc txheej yuav tsum tsis txhob tsawg tshaj li 610g / m2, thiab qhov nruab nrab thickness ntawm zinc txheej yuav tsum tsis txhob tsawg tshaj li 85um.5.Plastic txheej tom qab galvanizing ntawm lub suab barrier: zinc ingot siv rau galvanizing ( puab txheej) muaj cov kev cai zoo ib yam li kev kho kub-dip galvanizing.Sub 61um.Non-metallic txheej thickness: polyvinyl chloride, polyethylene yuav tsum tsis txhob tsawg tshaj li 0.25mm, polyester yuav tsum tsis txhob tsawg tshaj li 0.076mm.6.Kev tiv thaiv corrosion ntawm lub suab nrov barrier yuav tsum tau ua tom qab cov khoom ua tiav thiab kev soj ntsuam tau tsim nyog.Thaum cov tshuaj tiv thaiv tom qab kev tiv thaiv corrosion yog ua tiav dua, cov txheej txheem txheej txheem yuav tsum muaj kev tiv thaiv corrosion.
