- 摘要:
- 地震、滑坡等自然灾害都可能引起管道变形。文章结合抗大变形钢管的应用要求,试验研究了不同拉伸、弯曲变形对3PE防腐层的剥离强度、阴极剥离性能和冲击强度等的影响。结果表明:随着基材变形量的增大,3PE防腐层的剥离强度和阴极剥离性能变差,但变形对冲击强度的影响不显著;变形对于3PE防腐层的层间附着力影响较大,对底涂层FBE与基材的附着力影响最大。
Natural disasters such as earthquake and landslide are likely to produce pipeline deformations. According to the application requirements of large deformation resistance steel pipes, the experimental research on different tensile and bending deformations of substrate on peeling strength, cathodic peeling performance and impact strength of 3PE anticorrosion coating is conducted. The results show that with the increasing substrate deformation, the peeling strength and cathodic peeling performance of 3PE anticorrosion coating de- crease, but the effect of the deformation on the impact strength is unobvious; the deformation has a considerable effect on the interlayer adhesion capacity of 3PE coating and a maximum effect on the adhesion capacity between the FBE base layer and the substrate.2009,06(06): 33-35 收稿日期:2009-3-23分类号:TE988.2作者简介:张其滨(1964-),男,江西人,教授级高级工程师,1987年毕业于大连工学院,获硕士学位,2003年获美国MBA学位,主要从事防腐保温技术的研究和监督检验等工作。参考文献:
