Precautions for the manufacturer of display cabinets in the cultural relic porcelain showcase | Technology. The design of the cultural relic showcase showcases and the production cabinet production requirements are high. Not only are the showcases moisturizing, but also the display cabinet can have a temperature adjustment function.

In addition, the display cabinet is required to be able to use the light effects from a unique perspective. 1. The requirements of the cultural relics showcase: Due to the direct or indirect contact of the showcase and the 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 release harmful gases through contact with cultural relics or through their own aging, including sulfur dioxide, hydrogen sulfide, nitric oxide, ozone and volatile organic acids (samic acid and ethosic acid), volatile aldehydes (formaldehyde and acetaldehyde ) Waiting for cultural relics 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 inside of the inner lining, pad material and decorative materials of the showcase should be tested and chemically analyzed. The exact conclusion will not cause damage to the cultural relics.

Second, the performance requirements of cultural relics showcases: The showcase should have good sealing, and the inside 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. The moisture -absorbing buffer material can absorb the moisture under the humid climate in the summer.

In the winter dry climate, it can be released to keep the water in the exhibition cabinet stable. Staff needs to replace hygroscopic buffer materials according to the characteristics of climate. In other words, in the summer, the staff needs to put the moisture absorption buffer material after drying, so that it has the ability to absorb the ability to put it in the showcase to 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, so that it has the ability to release water and put it in the exhibition cabinet. 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 showcase, placing 2.

5 kg of silicone per cubic meter of cabinet can also meet the requirements. The silicone box of the lower layer of the showcase should have enough air pores for air exchange with the exhibition part of the upper cultural relics. 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 for the exhibition cabinet to control the 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 exhibition cabinet that needs the same temperature and humidity is connected with the same ventilation pipe, and at the same time, the air is sent back.

3. Cultural relic show cabinet light source requirements: The lighting in the showcase should be safe for cultural relics, that is, the cold light -free light -free light -free shooting 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 ventilation and discharge light emitting calories out of the cabinet. If the showcase uses light box lighting, then placing ultraviolet films between 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. .
