Modern museum showcases should meet the technical requirements for cultural relic protection

Museum showcases are spaces where the museum displays cultural relics and artworks to the audience with a true attitude and artistic effect. It is a direct place for silent communication between the museum and the audience. It is also the last line of defense for protecting cultural relics and ensuring their safety. Modern showcases in museums should meet the technical requirements for cultural relic protection.

1. 1.The materials used in the showcase must be stable and safe for the cultural relics.

2. 
   

3. Due to the direct or indirect contact between the showcase and the cultural relics, if the materials used in the showcase contain chlorine, sulfur or other acidic ingredients, it is bound to cause damage to the cultural relics. They cause damage to cultural relics through contact with them or through the release of harmful gases after their own aging, including sulfur dioxide, hydrogen sulfide, nitric oxide, nitrogen dioxide, ozone and volatile organic acids (formic acid and acetic acid), volatile aldehydes (formaldehyde and acetaldehyde). Showcase materials should be tested or chemical analysis before they can be used to manufacture cultural relics showcases. In general, materials that pose potential hazards to cultural relics include wood, paint, adhesives, leather, woolen goods, chemical fiber textiles and certain textile dyes. In other words, stainless steel, aluminum alloy and surface spray coating steel plates are safer than other materials.

4. 
   

In order to ensure the safety of cultural relics, the lining boards, cushioning materials and decorative materials of the showcases should be tested or chemically analyzed, and a definite conclusion can be drawn that they will not cause damage to the cultural relics before they can be used in cultural relics showcases.

2. The showcase should be able to control temperature and humidity. 

The showcase should have good sealing performance, and there should be automatic temperature and humidity measuring instruments and humidity control equipment installed inside.

The first option for controlling humidity in showcases 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 an alarm signal at the same time.

A second option for controlling humidity in showcases is to place hygroscopic buffering materials. This option requires sufficient space in the lower cabinet of the showcase for a moisture-absorbing cushioning material, such as silicone. The hygroscopic buffer material can absorb moisture in humid climates in summer and release moisture in dry climates in winter to keep the humidity in the showcase stable. Staff need to replace hygroscopic buffer materials at any time according to climate characteristics. That is to say, in summer, staff need to dry the moisture-absorbing buffer material so that it has moisture-absorbing ability and then put it into the showcase to be effective. In winter, staff need to put the hygroscopic buffering material into a small environment with high humidity to absorb enough moisture so that it has the ability to release moisture before it can be put into a showcase to be effective.

3. The lighting in the showcase should be safe for cultural relics.that is, cold-light spotlights without ultraviolet rays should be used. 

The brightness of each lamp should be adjustable through the knob in the box, and the light point should be freely adjustable. Optical fiber lighting can send light into the showcase lighting position and place the luminous heat source at a distant position. This kind of cold light spotlight is conducive to ventilation and discharges the luminous heat out of the cabinet. If the showcase is illuminated by a light box, a UV filter film should be placed between the lamp and the diffuser glass. The luminous spectrum of the lamp should be close to natural light. The heat of the lamp should be discharged out of the showcase through the exhaust equipment.
