对于世界范围内越来越多地在建筑业中使用铝材,其在加工和应用技术方面所显示出的优点,比如容易大工业生产,高的保护作用,被证实的耐大气腐蚀和机械磨损的稳定性,较低的比重,微少的维修费用,毫无疑义的还有多种装饰性表面处理的能力等因素,都具有决定性的意义.近二十年来,为了使铝制品能耐大气腐蚀的阳极氧化上色法不断改进以及新的多方面发展.就已说明了在建筑业中倾向于阳极氧化上色的原因.从加工技术和外观来看,主要有两种不同的上色,其质量标准可作以比较:即涂漆染色法和阳极氧化上色法、也包括用有机色素的吸附上色法涂色漆方法虽能达到无限的颜色范围,并满足最为广泛的调色要求,但由于色漆的不透明性.因此铝的金属特性,尤其是装饰性表面特性已被丧失.所以铝制品从其外观来看,就再也不能区别于其它涂漆法上色的部件了.而用阳极氧化上色法.因其上色的氧化膜具有一定的透明度,故能使材料保持理想的金属外观特征.所以,是否阳极化上色的铝材,一看就十分清楚.并且,它还能满足用户提出的高质量外观要求.其缺点就是颜色不均匀一致,颜色范围很有限.另外,上色的品种还与阳极化的现场设备有关
For the increasing worldwide use of aluminum in the construction industry, its advantages in terms of processing and application technologies such as easy large-scale industrial production, high protection, proven atmospheric corrosion resistance and mechanical wear and tear Stability, lower specific gravity, less maintenance costs, no doubt there are a variety of decorative surface treatment and other factors, have a decisive significance.In the past two decades, in order to make the aluminum products can be resistant to atmospheric corrosion The continuous improvement of the anodizing coloring method and the new multifaceted development have illustrated the reasons for the tendency towards anodizing in the construction industry. There are mainly two different colors depending on the processing technology and the appearance, the quality of which Standard can be used for comparison: paint staining and anodizing, but also with the organic pigment adsorption color coating method can reach an unlimited range of colors, and to meet the most extensive color requirements, but Due to the opacity of the paint, the metallic properties of aluminum, especially the decorative surface properties, have been lost, so the aluminum product can no longer be distinguished from other painted parts by its appearance Anodic oxidation coloring method because of its color oxide film has a certain degree of transparency, it can make the material to maintain the ideal appearance of the metal, so whether the anodized colored aluminum, it is clear at a glance, and it also Can meet the user’s requirements for high-quality appearance.The disadvantage is that the color is not uniform, the color range is limited.In addition, the color of the species and anodized on-site equipment
