Influence of Aluminum Extrusion Process on Coloring Effect of Aluminum Profile
The influence of extrusion process on oxidation coloring is mainly the influence of die design, extrusion temperature, extrusion speed and cooling method on the surface state and microstructure uniformity of the extruded profile.
The influence of extrusion process on oxidation coloring is mainly the influence of die design, extrusion temperature, extrusion speed, cooling method, etc. on the surface state and tissue uniformity of the extruded profile.
mold design should be able to make the feed fully kneaded, otherwise prone to bright (dark) with defects, the same profile may appear color separation; at the same time, the mold state and profile surface extrusion lines also affect the oxidation coloring. Extrusion temperature, speed, cooling method and cooling time are different, so that the profile organization is not uniform, will also produce color difference.
2. Surface Treatment-Anodizing
is mainly due to the poor conductivity of individual materials during the upper row of oxidized blanks before oxidation, thus making the oxide films relatively different, after coloring, it will produce color difference.
4. Electrolytic Coloring Process Affects
Electrolytic Coloring Process can directly reflect the color difference problem. The current distribution capability of electrolytic coloring liquid has a decisive influence on the uniform coloring of coloring materials. Once the current distribution is uneven, obvious color difference will be caused. The current distribution capability of
bath liquid is mainly related to the conductivity and polarization of the bath liquid. The coloring liquid contains a certain amount of conductive salt, mainly to improve the conductivity of the coloring liquid. When the conductive salt is not added in time, the conductive ability decreases and the current distribution ability decreases, which will cause color difference.
Kemet has always followed the development concept of "integration, innovation, and progress", vigorously implemented the value chain layout and big brand development strategy, and continued to innovate in the Chinese profile market, and successively won many honors: "National High-tech Enterprise", "National Specialized Special New Small Giant Enterprise", "Top 20 Chinese Construction Aluminum Profile Enterprises", "China Real Estate Building Insulation Aluminum Profile Preferred Strength Brand", "China Aluminum Industry Top Ten Ingenuity Brands", "China Aluminum Profile Industry Top Ten Influential Brands", "China Patent Shandong Star Enterprise", "Shandong Famous Brand", "Shandong Famous Trademark", "Shandong Contract-abiding and Credit-abiding Enterprise", "Mayor's Quality Award", etc, and has been continuously selected as the provincial and municipal construction industrial products association, doors and windows curtain wall professional committee chairman unit. Kemet products and Kemet brands have been widely recognized, and more and more Kemet products have been applied to landmark projects around the world.
Among many building materials, aluminum alloy doors and windows must be used in home decoration. As the first line of defense, doors and windows not only protect the safety of the home, but also reflect the taste of the room. In the face of a dazzling array of products, consumers should be how to choose the right aluminum alloy? In the strong promotional smoke of major businesses, the selection of a practical aluminum alloy products has become a point of concern for many people.
Winter goes to spring, the temperature rises, everyone began to prepare to decorate their favorite house, as the saying goes, "the four seasons of the year lie in spring", spring is undoubtedly a very important season in people's minds. Many people know that spring is suitable for farming, but did you know that spring is also a good season for decoration.
