| 摘 要： | 选择普通玻璃鳞片涂料、耐高温玻璃钢衬里两种防腐蚀材料制作混凝土试块，同时与无保护的混凝土试块一起在脱硫系统烟气区进行现场腐蚀试验，试验周期为3个月、6个月。对试验后防腐蚀层外观、混凝土中钢筋的腐蚀形貌以及混凝土中氯元素等进行分析。结果表明，无保护混凝土试块，外界腐蚀介质已渗透到混凝土内部，导致钢筋出现非常明显的腐蚀；普...

| Abstract: | The corrosion behavior of concrete and anticorrosion coatings in flue gas region of desulphurization system was studied by field testing for 3 months and 6 months.The test specimens included unprotected concrete and concrete block with glass flake coating or high temperature resistance glass fiber reinforced plastic lining.The outward appearance,corrosion morphology of rebar in concrete specimens and Cl~- content in concrete specimens were studied.The results show that Cl~- can permeate into the unprotected... |
