The difference between the two coloring methods of alumina board
Although there are several electrolytic coloring methods for aluminum oxide plates and aluminum alloys, and each method has its own characteristics, as long as the film function, coloring technology and equipment, and production cost are compared, the actual production situation can be compared with Choose the most suitable method for commodity demand.
The difference between the adsorption coloring method and electrolytic coloring method of aluminum oxide plate and aluminum alloy plate is as follows:
1. From the perspective of color contrast, the color type of the adsorption coloring method is relatively bright, and the colors of the other two methods are more coordinated, but the color type and series have less contrast. As a large number of construction sections, the firmness and stability of the color are very important factors, but the firmness and stability of the adsorption coloring are poor, and the contrast of electrolytic coloring is better. Best natural hair color (all colors). The good reason has a lot to do with the principle of coloring and the storage method of "pigments".
Pigments are adsorbed on the surface of the pores of the film, so they are simply lost under the action of strong light and strong heat, or change color or change color. Electrolytic pigments are accumulated at the bottom of the membrane holes. The color and color firmness are related to the accumulation of pigment and sealing technique. The pigments of the entire coloring method are combined with the entire three coloring principles, so they are the strongest and most stable.
2. Compare other functions of the membrane. It can be seen that the film fineness and corrosion resistance of the adsorption coloring method can be achieved, but the wear resistance is poor, and it is only suitable for interior decoration profiles and daily department store decorations or crafts.
The electrolytic coloring method color film has the advantages of fine color film, wear resistance, corrosion resistance, light resistance, heat resistance, etc., especially the corrosion of mortar and cement, and is most suitable for building profiles such as door frames and windows. The color film with natural hair color is the best, the film layer is very thin, the wear resistance, corrosion resistance, light resistance and heat resistance are also very good, but the performance is not as good as the electrolytic color film.
