Embodiment 1
[0040] The aluminum mesh used in this embodiment is a commercially available aluminum mesh with a thickness of 0.8mm and a width of 0.6m; the heat treatment furnace is a low temperature heat treatment furnace with a maximum operating temperature of 700°C, a mixed air system, and a PID three temperature zone for precise temperature control. The regional temperature difference is equal to minus 5°C; the maximum heating rate of the heat treatment furnace is 1°C / s.
[0041] The heat treatment method of the front panel aluminum plate mesh for the sound-absorbing panel provided in this embodiment includes five stages of primary heating, medium temperature insulation, secondary heating, high temperature insulation, and cooling.
[0042] Uncoil the commercially available aluminum mesh and cut it to the required specifications. Lay the cut thin aluminum mesh and place it naturally without compaction; put the whole aluminum mesh into the heat treatment furnace; the aluminum mesh is heated wit...
