一、前言用涂层保护管道是一种经济有效的措施。然而,要成功地应用涂层,表面处理是重要的一环。运到现场的钢管,内表面上往往有不同程度的氧化皮、锈蚀、毛刺、油污、水份和灰尘等表面缺陷和污物。这些表面缺陷和污物若不严格清理,则不能涂涂层。否则会降低涂层质量,影响使用寿命。表面处理的目的,是清除或减少表面缺陷和污物。为涂层提供具有一定粗糙度和清洁度的表面,这是保证涂层质量的关键。二、除锈方式现场管道内壁涂层的预处理,一般采用酸洗方法较好。但工序繁琐,劳动强度大,污染环境,危害操作人员身体健康。因此,多年来
I. Introduction Preserving pipes with coatings is a cost-effective measure. However, surface treatment is an important part of successful application of the coating. Pipe to the scene, the surface often have varying degrees of scale, rust, burrs, oil, water and dust and other surface defects and dirt. If these surface defects and dirt are not strictly cleaned, you can not apply the coating. Otherwise it will reduce the coating quality, affect the service life. The purpose of surface treatment is to remove or reduce surface defects and dirt. Providing the coating with a surface with a certain degree of roughness and cleanliness is the key to ensuring the quality of the coating. Second, the rust way In-situ pipe wall coating pretreatment, the general use of pickling method is better. However, complicated procedures, labor-intensive, pollute the environment, endanger the health of operators. Therefore, over the years
