The museum requires high requirements in the design and exhibition cabinet production. It not only requires the exhibition cabinet to moist. In addition, the showcase can be required.
1. The materials used in the display cabinet must be safe for the cultural relics because of the direct or indirect contact of the showcase and cultural relics. If the materials used in the showcase contain chlorine, sulfur or other acidic ingredients, it will inevitably cause damage to the cultural relics damage.
They are exposed to cultural relics or released harmful gases after their own aging, including sulfur dioxide, hydrogen sulfide, nitric oxide, nitric oxide, ozone and volatile organic acids (samic acid and ethyl) ) Waiting for cultural relics damage. The display cabinet materials should be used to make cultural relics showcases after testing or chemical analysis. Generally speaking, the materials that cause lurking 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 lining plate, pad material and decorative materials in the showcase should be tested or chemically analyzed that the conclusion that the conclusion will not cause damage to the cultural relics. 2.
The showcase should be able to control the temperature and humidity showcases should be well sealing, and the internal equipment should be installed with equipment with temperature and humidity automatic measurement instruments and controlling humidity. The first choice for the exhibition cabinet to control humidity is to install the dehumidifier. When the humidity exceeds the range of required, the humidity controller can automatically turn on 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 enough space to leave enough space in the box in the lower layer of the showcase to place moisture -absorbing buffer materials, such as silicone. Moisturizing materials can absorb tide in the summer humid weather.
In the winter, it can be released in dry weather to keep the water in the showcase not chaotic. Employees need to replace moisture -absorbing buffer materials at any time according to the weather characteristics. In other words, the staff in the summer needs to put the moisture absorption buffer material through the drying of it, so that it can be put into the showcase to perform the role.
In winter, the staff needs to put the moisture -absorbing buffer material in a small environment with a large humidity to absorb sufficient water, so that it has the ability to release water and put it in the showcase. Experience of the Canadian Museum: According to the experience of the Canadian Museum, the space per cubic meter of the counter should be placed in about 20 kilograms of silicone. For a well -sealed display cabinet, it is also possible to meet the requirements of 2.
5 kg of silicone per cubic meter of the showcase. The silicone box of the lower layer of the showcase should have enough air pores to exchange air exchange with the upper cultural relics exhibition department. The purpose of reserving hygroscopic buffer materials in the lower layer of the showcase is to not affect the exhibits in the showcase when replacing the silicone, that is, no mobile exhibits need to be.
The third choice of the exhibition cabinet controls temperature and humidity is to control the temperature and humidity of the display cabinet by the central air -conditioning pipeline connection method. The Shanghai Museum uses this method. The showcases that need to be unified and humidly connect are connected with a unified air permeability pipe, and at the same time, the air will be sent back.
3. Requirements for display cabinets: Lighting in the showcase should be safe for cultural relics, that is, the cold light -free light -free light -free light -free lights should be used. Light -guided fiber lighting can send the lights into the lighting position of the showcase, and place the light emitting heat at a distance.
This kind of cold light shooting light is conducive to the ventilation of light emitting heat out of the cabinet. If the display cabinet uses light box lighting, then placed ultraviolet film in the lights and astigmatism glass. The luminous spectrum of the lamp should be close to natural light.
The calories of the light should be able to discharge through the exhaust device outside the showcase. .
