       Research on the current status of aluminum-magnesium alloy aluminum sheet

       With the high-grade living environment, the new aluminum-magnesium alloy aluminum plate was transferred from abroad to China. All aluminum-magnesium alloy aluminum plate manufacturers have introduced foreign insulated bridge wear-through equipment, and domestic enterprises engaged in aluminum processing equipment have also developed insulated bridge wear-through equipment. Both hope to push the new aluminum-magnesium alloy aluminum plate to the market. The production cost of the heat-insulating aluminum-magnesium alloy aluminum plate is higher than that of the ordinary aluminum-magnesium alloy aluminum plate, and the processes of penetration, oxidation, spraying, and wearing are increased. The insulating cavity filled polyurethane foam process is for the foamed heat-insulating aluminum-magnesium alloy aluminum plate, and the profile is placed in a two-component metering compounder, and is naturally foamed by pouring into the heat insulating cavity through the mixing nozzle. By wearing a broken bridge connection, the silver oxide white material can be connected with the color spray paint, the sand fabric and the coloring material; the decorative feeling of the profile is increased. The details are as follows.

       The heat-insulating strip aluminum-magnesium alloy aluminum plate is a combination of aluminum-magnesium alloy aluminum plate and thermoplastic mixed material heat insulation strip. Rolling heat-insulating aluminum-magnesium alloy aluminum plate is made of high-density polyamide PA66 strip with good heat insulation performance, or polyvinyl chloride hard plastic strip is rolled and processed to make aluminum and plastic into one body. Foamed heat-insulating aluminum-magnesium alloy aluminum plate is made by inserting inner and outer aluminum-magnesium alloy aluminum plates into one body by using heat-insulating strips, filling polyurethane foam in the formed heat-insulating cavity, and becoming "cold" of heat-insulating aluminum-magnesium alloy aluminum plate Bridge", to achieve the effect of insulation and energy saving. The domestic production line of heat-insulating aluminum-magnesium alloy aluminum plate, the main production technology is "rolling embedded", whether it is the introduction of foreign or domestic equipment, the use of "three-step" production process, that is, open teeth, wear strips, Rolling. Some companies are studying the "two-step" production process, which will start the teeth and wear the strips synchronously, but the basic principle is the same, but the process time is shortened.

       The first process is mainly to check the surface quality and size specifications of the profiles. The inner and outer aluminum-magnesium alloy aluminum plates can be anodized or electrostatic powder sprayed profiles. The inner and outer aluminum-magnesium alloy aluminum plates can also be made of different color ingredients, and connected through a broken bridge to form inner and outer two-color aluminum alloy doors and windows. The second process is to apply a protective film to protect the surface quality of the profile from damage during processing and handling. Toothing is a key process, mainly in the formation of a serrated tooth path on the inner walls of the heat-insulating aluminum-magnesium alloy aluminum plate. The polyvinyl chloride rigid plastic strips are embedded by rolling and held together. At present, there is no specific regulation on the tooth depth in China, but it is in the industry standard JC/T building insulation aluminum-magnesium alloy aluminum plate standard. The values of tensile strength and shear strength are specified, so that the toothed belt must be connected to the aluminum-aluminum alloy heat-insulating strip and the aluminum-magnesium alloy aluminum sheet by roller. The stripping and rolling process is an important process. The strip is made of PVC rigid plastic insulation strip, which is inserted into the toothed heat-insulating aluminum-magnesium alloy aluminum plate through the wearing device and then passed through the rolling equipment. The heat-insulating aluminum-magnesium alloy aluminum plate is pressed together with the polyvinyl chloride hard plastic strip.
