The display cabinets should be well sealed and equipped with automatic measuring instruments for temperature and humidity and equipment for humidity control. The equipment is not allowed to be installed with the display cabinet.
The first choice for the display cabinet to control humidity is to install a dehumidifier. When the humidity exceeds the required range, the humidity controller can automatically turn on the dehumidifier to reduce the humidity and display the alarm signal at the same time.
The second option for the display cabinet to control humidity is to place a hygroscopic buffer material. This option requires that enough space be left in the lower compartment of the display cabinet to place hygroscopic buffers, such as silica gel. The moisture absorbent buffer material can absorb moisture in the humid climate in summer, and can release moisture in the dry climate in winter to keep the humidity in the display cabinet stable. Staff members are required to replace moisture absorbent buffers at any time in accordance with climate characteristics. The lower part of the cabinet should have enough air holes for air exchange with the upper part of the exhibition. The purpose of reserving the wet-absorbing buffer material box body at the lower level of the display cabinet is that when replacing the silicone gel, it should not affect the exhibits in the exhibition cabinet, that is, there is no need to move the exhibits.
