Powder spraying has the following significant advantages:
1. The process is relatively simple, mainly due to the improvement of the automatic accuracy of the main equipment in the production process, the microcomputer control of some main technical parameters can be achieved, which effectively reduces the difficulty of process operation, and the auxiliary equipment is greatly reduced.
2. High yield, normally, the appropriate measures maximize the control of the production of unqualified products.
3. Energy consumption is significantly reduced. In the production process of ordinary anodized and electrophoresis coating, the consumption of water and electricity is quite large, especially in the anodized process.Rectifier output current can reach 8000~11000A, voltage between 15~17.5V, coupled with the heat consumption of the machine itself, the need to keep cooling with circulating water, ton of power consumption is often about 1000 degrees, at the same time, the reduction of auxiliary facilities can also reduce some power consumption.
4. The degree of pollution to water and air is reduced, the flake alkali, sulfuric acid and other liquid organic solvents are no longer used, reduce water and air pollution, but also effectively improve the competitive strength of aluminum profile and plastic steel profile as environmental protection products, and reduce some production costs accordingly.
5. The labor intensity of the workers is significantly reduced. Because of the use of automatic assembly line, the feeding method and the use of the fixture have been significantly simplified, which improves the production efficiency and reduces the labor intensity.
6. The requirements for the surface quality of the wool are significantly reduced. The powder coating can completely cover the extrusion grain on the surface of the profile, cover up the defects on the surface of a part of the aluminum profile, and improve the surface quality of the finished aluminum profile.
7. Compared with other surface treated films, some physical indexes of the film are improved obviously, such as hardness and wear resistance, which can effectively prolong the service life of aluminum profiles.
Powder spraying is powder coating, electrostatic spraying is used in the process, the use of friction spray gun, under the influence of the accelerated wind, the powder particles ejected gun body carrying positive charge, and a negative charge profile contact, electrostatic adsorption, and then after high temperature curing.It also enhances the adsorption strength of the paint and prevents the paint film from falling off.g is powder coating, electrostatic spraying is used in the process, the use of friction spray gun, under the influence of the accelerated wind, the powder particles ejected gun body carrying positive charge, and a negative charge profile contact, electrostatic adsorption, and then after high temperature curing.It also enhances the adsorption strength of the paint and prevents the paint film from falling off.
From the point of view of the process itself, has a very high scientific and technological components, the deployment of different colors of paint, produce different color decorative effect, more in line with the needs of interior decoration, is also consistent with the application of aluminum in the construction industry to the trend of indoor development.In particular, the combined use of spray profile and heat insulation broken bridge makes it more fashionable, so that the powder spray profile has a greater space for development, but also the profile produced by other processing methods can not be replaced.
