1. The appearance quality requirements of the wool are significantly reduced. The powder coating can completely cover the extrusion lines on the surface of the profile, cover up the defects on the surface of a partial aluminum profile, and improve the appearance quality of the aluminum profile waste products.
2.Some physical indicators of coating film compared with other surface treatment film has significantly improved, such as hardness, wear resistance, acid resistance, can effectively extend the service life of aluminum profiles.
Powder coating used in powder spraying, electrostatic spraying process, using the effect 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 paint and prevents paint film from falling off.
From the process itself, has the very high science and technology, deployment of color coating, different color adornment effect, more in line with the needs of the interior decoration, with aluminum in the application of the construction conform to the trend of the development of the indoor especially spraying profile with insulation broken bridge joint use, make it have more fashion trends, more make powder coating profiles have the larger development space, and cannot be replaced by other disposal mode of production in profile.
