What is the exhaust gas of aluminum anodizing process

The waste gas of aluminum anodizing process is the hydrogen precipitated from the cathode plate, and the oxygen precipitated from the anode plate reacts with the aluminum to form an oxide film. The oxidation process produces only these two gases, but the whole oxidation process uses volatile acids in the pre-treatment, so there will be a lot of acid mist volatilized.

Aluminum alloy anodic oxidation process (including anodic oxidation, electrolytic coloring, hole sealing, etc.), chemical conversion and polishing treatment of the tank composition and process parameters, at the same time, the chromium-free chemical conversion treatment, functional anodic oxidation film and other aluminum alloy surface treatment technology were explained; The properties and detection methods of aluminum anodized film are described in detail, as well as the causes and prevention measures of anodized film defects. The appendix includes the components of deformed and cast aluminum alloys at home and abroad, the methods of tank analysis, the names of Chinese standards and relevant foreign standards and names of anodic oxidation, and the main journals in China and abroad, etc.
