Drying is an indispensable part in the surface treatment of aluminum alloys, and it needs to be dried after the processing is completed or after the graphics and text are transferred. Commonly used drying methods include natural drying and heated drying (that is, drying).
1. Natural drying Natural drying is suitable for workpieces with low requirements for aluminum natural color oxidation or dyed workpieces. This method does not require heating, so the drying rate is slow. Due to the high ambient temperature in the south, natural drying is also a way to save drying costs. When using natural drying, you must pay attention to the water quality when cleaning the surface-treated workpieces to prevent the workpieces from being imprinted after they are dried.
2. Drying Drying is the most commonly used drying method in aluminum alloy surface treatment. According to the different baking temperature, it can be divided into low-temperature drying, medium-temperature drying and high-temperature drying.
(1) Low-temperature drying Low-temperature drying refers to the drying method when the baking temperature is lower than 100°C. Low-temperature drying is mainly used for drying after aluminum alloy anodization. For ordinary sulfuric acid anodizing, the drying temperature should be controlled within 80°C. . The drying of the graphic anti-corrosion layer of aluminum alloy after anodic oxidation should also be controlled within 100℃.
(2) Medium-temperature drying Medium-temperature drying refers to a drying method with a temperature in the range of 100 to 150°C. This drying method is suitable for drying without anodization.
(3) High-temperature drying. Drying at a temperature above 150°C is a high-temperature drying. High-temperature drying is only used when electrophoretic coatings are used. The drying temperature is generally 180-200°C. See more https://www.aluminum-price.com/
