Aluminum alloy generally used in dining room, kitchen, bathroom and other top manufacturers of long-term supply of aluminum fridge, the construction, the first sheet to be dry and flat base surface, preferably with plywood, block board to do the bottom, to prevent cracking deformation. Secondly, when you paste the aluminum plate to pay attention to the refrigerator must be uniform coating of aluminum using a method to be volatile glue thinner to touch the sticky paste with a wooden hammer percussion compaction. Third, pay attention to the use of aluminum plate in accordance with design requirements divided into several blocks. Not the whole or a large area, otherwise easily lead to hollowing open plastic. Fourth, aluminum composite panel seams inro generally sealed with glass, plastic, glass, plastic injection requires closure must be uniform when the refrigerator full aluminum surface is dry to clean up, so the line thickness is consistent. What factors will lead alloy aluminum machinery substandard performance? 1, not homogenized ingot processing, the Ingots precipitated Mg2Si phase can not squeeze in a relatively short time to re-solid solution, resulting in a solid solution is not sufficient to affect the performance of aluminum alloy products; 2, improper aging process, Hot air circulation or thermocouple mounting position is incorrect, resulting in inadequate or excessive aging aging; 3, ingot component failure, the ingot of Mg, Si content is not up to standard requirements; 4, at the outlet of a small aluminum alloy fan air volume is not enough, resulting in slow cooling refrigerator Supplying aluminum, aluminum alloys can not make in the shortest possible time dropped below 200 ℃, so coarse Mg2Si precipitates prematurely, allowing the solid solution phase to reduce the impact of heat-treated aluminum alloy mechanical properties; 5, when the temperature is too low alloy aluminum extrusion, extrusion speed is too slow, the outlet temperature profile in the extruder reach the solution temperature, would not achieve the solid solution strengthening effect.
