Museum showcase Function: The showcase is the museum's space to show cultural relic art with a real attitude and artistic effect. It is a direct place for museums and audiences to communicate silently. The materials used in the showcase must be stable and safe for the cultural relics due to direct or indirect contact with the exhibition cabinet and cultural relics.
They release harmful gases by exposing cultural relics or through their own aging, including sulfur dioxide, hydrogen sulfide, nitric oxide, nitric oxide, ozone and volatile organic acids, volatile aldehyde, formaldehyde and acetaldehyde, etc. Cultural relics cause damage. The display cabinet material should be used for the manufacture of cultural relics showcases after testing or chemical analysis.
Generally speaking, materials that cause potential harm to cultural relics include wood, paint, adhesive, leather, woolen, chemical fiber textiles, and certain textile dyes. In other words, stainless steel, aluminum alloy and surface -spraying coating steel plates are safer than other materials. In order to ensure the safety of cultural relics, the inner lining plate, pad material and decorative materials of the showcase should be tested or chemically analyzed that the exact conclusion will not cause damage to the cultural relics.
The display cabinet should be able to control the temperature and humidity showcases should be well sealing, and the internal equipment should be installed with a device with a temperature and humidity instrument and controlling humidity. The first choice for the exhibition cabinet to control humidity is to install the dehumidifier. When the humidity exceeds the requirements range, the humidity controller can automatically open the humidifier to reduce the humidity and display the alarm signal at the same time.
The second option of the exhibition cabinet control humidity is to place hygroscopic buffer materials. This choice requires that there is enough space in the box in the lower layer of the showcase to place hygroscopic buffer materials such as silicone. Wet -absorbing buffer materials can absorb moisture under the humid climate in the summer.
Under the dry climate in winter, water can be released to keep moisture in the showcase stable. Staff needs to replace hygroscopic buffer materials according to the characteristics of climate. In other words, the staff needs to put the moisture -absorbing buffer material after drying it so that it has the ability to absorb it in the showcase before they can play a role.
In winter, the staff needs to put the moisture -absorbing buffer material in a small environment with a large humidity to absorb enough water to make it have the ability to release the water and put it in the showcase. Experience of the Canadian Museum. According to the experience of the Canadian Museum, about 20 kilograms of silicone should.
Putting 2.5 kg of silicone in the exhibition cabinet space per cubic meter of the showcase can also meet the requirements. .
