| 中文摘要: |
| 目的 结合涂层老化评价标准，利用层次分析法，量化评价储罐外涂层的老化状态。方法 通过研究涂层老化评级方法的标准，并引入层次分析法，计算得到单项老化性能指标占综合指标的权重，进一步构建涂层老化的数学模型以量化评价涂层状态。结果 利用层次分析法计算得到生锈、剥落、开裂、气泡和粉化5项指标所占权重分别为0.508、0.292、0.107、0.061和0.032，其中生锈所占权重最高。对南宁某油库外涂层防腐老化性能进行检测评价，检测结果显示，罐壁8层罐圈板仅有3层涂层老化状态得分处于45~50分之间，其余5层罐圈板以及罐顶、附件涂层老化状态均小于44分，综合老化情况及经济效益，建议对该罐外涂层整体进行重涂。结论 目前的涂层老化评价标准仅对涂层老化的评价方法以及评级进行了规定，但存在量化不足、未给出维修建议等缺点，引入层次分析法，可量化外涂层的老化状态，并可以根据量化评价结果给出维修建议。 |

| The work aims to quantitatively evaluate the aging state of the outer coating for storage tank through evaluation criteria for coating aging and analytic hierarchy process. By studying and comparing the standard of coating aging rating method and introducing the analytic hierarchy process, the weight of a single aging performance index respected to the total index was calculated to establish the mathematical model of coating aging to quantitatively evaluate the coating state. The weight of rust, flaking, cracking, blistering and powdering calculated by analytic hierarchy process was 0.0508, 0.0292, 0.107, 0.061 and 0.032, respectively, among which rust had the highest weight. The anti-corrosion aging performance of an oil depot in Nanning was tested and evaluated. The test results showed that the aging state scores of only 3 layers among 8 layers of ring plates on the tank wall were between 45 and 50, and the aging state scores of the other 5 layers of ring plates, tank top and accessories were all less than 44. Considering the aging situation and economic benefits, it was recommended to re-coat the whole outer coating of the tank. The current evaluation standard for coating aging only has a stipulation scales on the evaluation method and rating of coating aging and has some shortcomings such as insufficient quantization and missing maintenance suggestions. By introducing the method of analytic hierarchy process (AHP), the aging state of outer coating can be quantified. Based on the quantitative evaluation results, appropriate maintenance suggestions can be given directly. |
