The Ash and Nickel Remover CN - 907 after Sealing is meticulously developed for the post-treatment process of the sealing of anodized films on aluminum materials. It plays a crucial role in this process and can efficiently and accurately remove the ash and nickel generated on the product surface during the sealing process.It has many remarkable characteristics. Firstly, it is completely free of nickel and other heavy metal components, which can significantly reduce the nickel content on the surface of the anodized film and greatly ensure environmental protection and safety. Secondly, it can effectively improve the anti-fouling property and weather resistance of the anodized film, enhancing the durability and stability of the product. Moreover, it has a remarkable effect in reducing the sealing ash. In addition, it can extend the service life of the nickel sealing bath solution, reduce related emissions, and achieve efficient resource utilization and environmental friendliness.In terms of properties, CN - 907 presents as a colorless or slightly light blue liquid and is weakly acidic. There are clear specifications for its usage conditions. The standard proportion for preparing the tank solution is 70g/L, which can be flexibly adjusted within the range of 50 - 100g/L. The standard pH value is 2.5, ranging from 2.0 to 3.0. The standard temperature is set at 90°C, and the operating temperature range is 70 - 95°C. In terms of time, the standard duration is 5 minutes, and it will be adjusted within the range of 3 - 10 minutes according to different products.
