The general surface treatment methods of aluminum profiles
are: anodizing, electrophoretic coating and powder spraying. Each treatment method has its own advantages and occupies a considerable market share. Let me talk about the advantages of aluminum powder coating: 1. The process 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 reducing the process Operation is difficult, and auxiliary equipment is greatly reduced; 2, the yield rate of aluminum profiles is high, under normal circumstances, if various measures are appropriate, the production of unqualified products can be controlled to the greatest extent; 3, energy consumption is significantly reduced, in ordinary In the production process of anodic 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, the pollution to water and air is reduced, caustic soda, sulfuric acid and other liquid organic solvents are no longer used, reducing water and air pollution, and effectively improving the aluminum profile and As an environmentally friendly product, the competitive strength of plastic steel profiles has correspondingly reduced some production costs; 5. The labor intensity of aluminum profiles 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 Production efficiency also reduces labor intensity; 6. The surface quality requirements of the wool have been significantly reduced. 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 of the finished aluminum profile. Quality; 7. Some physical indexes of aluminum profile coating film are significantly improved compared with other surface treatment films, such as hardness and wear resistance, which can effectively extend the service life of aluminum profile.
