中文摘要:
      阳极氧化膜封孔质量的好坏,会直接影响阳极氧化膜的使用寿命。硝酸预浸是欧洲标准中规定的外部建筑用铝合金阳极氧化膜封孔质量检测的仲裁方法,文中考察了硝酸预浸在封孔质量检测中的作用,结果表明:硝酸预浸有溶解氧化膜和扩孔的作用,在封孔质量检测中引入硝酸预浸,不仅严格了对封孔质量的要求,而且使得封孔质量的判别更为灵敏。
英文摘要:
      Sealing quality directly affects the service life of the anode anodic oxidation coatings. For the anodic oxidation coatings intended for exterior buildings, the phosphoric/ chromic acid immersion with prior nitric acid treatment test method is specified as arbitration method in european standard. The effect of the prior nitric acid treatment on sealing quality test was studied. The results show that the prior nitric acid treatment has the action of dissolution and enlargement. The introduce of the prior nitric acid treatment in sealing quality test provides a more strict sealing quality test method, makes the sealing quality discrimination becoming more sensitive.
