Advantages of aluminum profile powder coating surface treatment

 

1. The process is relatively simple, mainly due to the improvement of the automatic accuracy of the main equipment in the production process, some of the main technical parameters can already achieve micro-computer control, effectively reduce the difficulty of process operation, while the auxiliary equipment greatly reduced

 

2. High yield, in general, if the measures are appropriate, can maximize the control of non-conforming products

 

3. Energy consumption is significantly reduced, in the ordinary anode oxidation, electrophoretic coating production process, water, electricity consumption is considerable, especially in the oxidation process. The output current of the rectifier can reach between 8000 and 11000A, the voltage is between 15 and 17.5V, plus the heat consumption of the machine itself, it needs to keep using circulating water to cool down, the ton power consumption is often around 1000 degrees, while the reduction of auxiliary facilities can also reduce some power consumption;

4. Reducing the degree of pollution of water and atmosphere, no longer using tablet alkali, sulfuric acid and other liquid organic solvents, reducing water and air pollution, and effectively improving the competitive strength of aluminum profiles and plastic steel profiles as environmentally friendly products, correspondingly reducing some production costs;

5. The labor intensity of the workers is obviously reduced, due to the use of automated assembly line operation, the method of feeding and the use of fixtures have been significantly simplified, improve the production efficiency, but also reduce the labor intensity;

 

6. The surface quality requirements of the wool material are obviously reduced, the powder coating and can fully cover the surface of the profile squeeze grain, cover up some of the aluminum profile surface defects, improve the surface quality of the finished aluminum profile;

 

7. Some physical indicators of coating film are significantly improved compared with other surface treatment films, such as hardness, wear resistance, can effectively extend the service life of aluminum profiles. Powder spraying is the use of powder coating, the process is the use of electrostatic spraying, the use of friction gun, under the influence of accelerated wind, so that powder particles sprayed out of the gun body with a positive charge, with a negative charge of the profile contact, the production of electrostatic adsorption, and then after high temperature curing. It also enhances the adsorption strength of the coating to prevent the paint film from falling off.
