Anodizing can significantly improve the corrosion resistance of aluminum alloys, increase the surface hardness and wear resistance of aluminum alloys, and have good decorative properties after appropriate coloring treatment. Aluminum and its alloy anodic oxide film coloring technology can be divided into three types: chemical dyeing, electrolytic coloring and electrolytic overall coloring. Chemical dyeing uses the porosity and chemical activity of the oxide film layer to adsorb various pigments to color the oxide film. According to the coloring mechanism and process, it can be divided into organic dye coloring, inorganic dye coloring, color paste printing, overcoloring dyeing and decoloring dyeing. Wait. Electrolytic coloring is the alternating electrolysis of anodized aluminum and its alloys in an aqueous solution containing metal salts, and the deposition of metals, metal oxides or metal compounds on the bottom of the porous layer of the oxide film, due to the scattering of light by the electrodeposits Present a variety of colors. Electrolytic overall coloring means that aluminum and its alloys are colored at the same time as anodizing. It is characterized by the completion of oxidation and coloring in one step. The colored film has good light resistance, heat resistance, corrosion resistance and wear resistance. The overall electrolysis coloring is divided into natural hair color, electrolytic hair color and power color hair method, in which electrolytic hair color is dominant, natural hair color is second, and power hair color is under development.

General industrial aluminum profiles: Mainly used in industrial production and manufacturing, such as automated machinery and equipment, the skeleton of the enclosure, and the companies customize the molds according to their own mechanical equipment requirements, such as assembly line conveyor belts, elevators, dispensers, Testing equipment, shelves, etc., are mostly used in the electronic machinery industry and clean rooms. 4. Aluminum alloy profile for rail vehicle structure: mainly used in the manufacture of rail vehicle body. 5. Mounting aluminum profiles to make aluminum alloy picture frames, mounting various exhibition and decorative paintings. According to the alloy composition, it can be divided into alloy grade aluminum profiles such as 1024, 2011, 6063, 6061, 6082, 7075, among which the 6 series is the most common. The difference between different grades is that the proportions of various metal components are different, except for commonly used In addition to architectural aluminum profiles such as 60 series, 70 series, 80 series, 90 series and curtain wall series, industrial aluminum profiles do not have a clear model distinction. Most manufacturers process them according to the actual drawings of customers. European standard aluminum profiles are well received by the market due to their unique characteristics and better results. So there are two types of aluminum profiles in the market, the European standard and the national standard. What is the difference? In fact, the biggest difference between European standard aluminum profile and national standard aluminum profile is: 1. The groove type is different, and the fixed connection of the profile is to prevent different nuts in the profile groove. Ordinary nuts are placed in the national standard profile slot, and special nuts are placed in the European standard profile. 2. The corners of the profile are different. The four corners of the national standard profile are very small, basically right-angled. The four corners of the European standard profile have large arc chamfers.

Broken bridge thermal insulation aluminum door and window is also called broken bridge aluminum, thermal insulation aluminum alloy, and broken bridge aluminum alloy. Both sides are made of aluminum, and the middle is made of plastic profile cavity as thermal insulation material. This innovative structural design takes into account the advantages of both plastic and aluminum alloy materials, while meeting various requirements for decorative effects, door and window strength, and aging resistance. The principle of Broken bridge thermal insulation aluminum alloy is to insert a thermal insulation strip in the middle of the aluminum profile to break the aluminum profile to form a broken bridge, which effectively prevents the conduction of heat. The thermal conductivity of insulated aluminum alloy profile doors and windows is 40-70% lower than that of non-insulated aluminum alloy profile doors and windows. Broken bridge aluminum is made of door and window frame fans, equipped with insulating glass, hardware, screens, glass glue, styrofoam, sealing strips, etc., and the door windows processed in this way are called broken bridge insulated aluminum doors and windows profile. ◆ ◆ ◆ Analysis of the advantages of thermal insulation aluminum for broken bridges: 1. Broken bridge thermal insulation aluminum has good thermal insulation. The inner and outer frames of the heat insulation profile are softly combined, and the frame is sealed with EPDM tape, which is tightly closed, has excellent air and watertight performance, and has superior thermal insulation performance; the window sash adopts hollow glass structure, so that the window truly shows sound insulation and insulation.
