Understand the surface treatment methods of industrial aluminum

The surface treatment methods of industrial aluminum generally have three treatment methods: anodizing, electrophoretic coating and powder spraying. Each method has its own advantages and occupies a considerable market share. Powder spraying has the following significant advantages: 1. The process of industrial aluminum is relatively simple, mainly due to the improvement of the automatic accuracy of the main equipment in the production process, and the microcomputer control of some main technical parameters can be achieved effectively. Reduce the difficulty of process operation, while the auxiliary equipment is greatly reduced; 2. The yield is high. Under normal circumstances, if various measures are appropriate, the production of unqualified products can be controlled to the greatest extent; 3. The energy consumption is significantly reduced. In the production process of oxidation and electrophoretic coating, the consumption of water and electricity is quite large, especially in the oxidation process. The output current of the rectifier can reach between 8000~11000A, and the voltage is between 15~17.5V. In addition to the heat consumption of the machine itself, it is necessary to continuously use circulating water to cool down, and the electricity consumption per ton is often about 1000 degrees. At the same time, the reduction of auxiliary facilities can also reduce some power consumption; 4. Reduce the pollution of water and air, and no longer use caustic soda, sulfuric acid and other liquid organic solvents, reduce water and air pollution, and effectively improve aluminum profiles and The competitive strength of plastic steel profiles as environmentally friendly products has correspondingly reduced some production costs; 5. The labor intensity of industrial aluminum profile workers has been significantly reduced. Due to the use of automated assembly line operations, the feeding method and the use of fixtures have been significantly simplified and improved The production efficiency is improved, and labor intensity is also reduced; 6. The surface quality requirements of industrial aluminum wool material have been significantly reduced, and the powder coating can completely cover the extrusion lines on the surface of the profile, conceal some of the defects on the surface of the aluminum profile, and improve The surface quality of the finished aluminum profile; ————The article comes from the Internet.
