摘要
通过划伤试验和测试数据的可靠度分析,研究了三种管道外防护层的抗划伤性能。结果表明,DPS涂层抗划伤性能明显优于3 PE和FBE涂层,增加涂层厚度可以减少涂层被划伤至基体的危险;不同厂家生产的同类型材料所涂敷的涂层的抗划伤性能存在明显差异;划伤重量是影响划伤深度的最主要因素;所采用的划伤试验方法基本上能够反映现场实际情况,适合工程应用中对管道外防护涂层及其原材料抗划伤性能的评定和筛选。
The gouge resistance of three kinds of pipeline external coating was evaluated by using gouge test and data analysis of reliability. The results showed that the resistance of DPS coating was better than that of 3-PE and FBE. Increase of the thickness of coatings could reduce the of damage risk of the substance due to coating gouge. Apparent differences in the gouge resistance existed among the products of the same kind but from different manufacturers. Weight of gouge was the most important among the parameter affecting gouge depth. The gouge test used can simulate the situation in field and so is suitable for evaluation and selection of pipeline external coating in engineering.
