What are the advantages of powder coating for industrial aluminum profile treatment?
Industrial aluminum profiles generally have three treatment methods: anodizing, electrophoretic coating, and powder coating. Each method has its own advantages and holds a considerable market share. Nano Powder Coatings Manufacturer explains the appearance of industrial aluminum Advantages of powder coating treatment.
Nano Self-Cleaning Powder Coatings
Powder Coatings has the following significant advantages:
1. The process is relatively simple, mainly due to the improvement of the active accuracy of the main equipment in the production process. Microcomputer control has been achieved for some of the main technical parameters, which effectively reduces the difficulty of the process operation, and greatly reduces the auxiliary equipment.
2. High yield, under normal circumstances, if the measures are appropriate, the production of non-conforming products can be controlled;
3. Energy consumption is significantly reduced. In the production process of ordinary anodizing and electrophoretic coating, the consumption of water and electricity is considerable, especially in the oxidation process. The output current of the rectifier can reach 8000 ~ 11000A, and the voltage is between 15 ~ 17.5V. In addition to the heat consumption of the machine itself, it is necessary to keep cooling with circulating water. The reduction of auxiliary equipment can also reduce some power consumption;
4. The degree of pollution to water and the atmosphere is reduced, the use of tablet alkali, sulfuric acid and other liquid organic solvents is no longer used, water and air pollution is reduced, and the competition strength of aluminum profiles and plastic steel profiles as environmental protection products is effectively improved, and accordingly Cut some production costs;
5. The labor intensity of workers has decreased significantly, because the use of active assembly line operations, the feeding method and the use of fixtures have been significantly simplified, improving production efficiency, and reducing labor intensity;
6. There is a significant decrease in the quality standards for the appearance of wool. The powder coating can completely cover the kneading pattern on the appearance of the profile, cover up some defects on the appearance of the aluminum profile, and improve the appearance quality of the finished aluminum profile.
7. Some physical indicators of the coating film have significantly improved compared with other surface treatment films, such as hardness and abrasion resistance, which can effectively extend the service life of aluminum profiles.
Powder coating is used for powder spraying, and electrostatic spraying is used for technology. Using the effect of friction spray gun, under the influence of accelerated wind, the powder particles are sprayed with positive charge when sprayed out of the gun body, and touch the negatively charged profile. Generates electrostatic adsorption and then cures at high temperatures. It also enhances the paint's adsorption strength and prevents the paint film from falling off.
