Several elements of museum showcase production and design

Basic elements; museums have high requirements in the design and production cabinet production, not only require the exhibition cabinet to provide the excellent preservation space moisturizing the exhibits, but also the exhibition cabinet can have temperature and humidity adjustment function. It must have different cultural relics protection functions and environment according to different types of exhibits, and the materials must be designed according to different types of exhibits. 1.

The materials of the showcase must be stable and safe. Due to direct or indirect contact with the exhibition cabinet and cultural relics, if the materials used in the showcase contain chlorine, sulfur or other acidic ingredients, It is bound to cause damage to cultural relics. They release harmful gases through contact with cultural relics or through their own aging, including sulfur dioxide, hydrogen sulfide, nitric oxide, nitric oxide, ozone and volatile organic acids (samic acid and ethosic acid), volatile aldehyde ) 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 the cultural relics, the lining plate, pad material and decorative materials of the showcase should be tested or chemically analyzed. The exact conclusion will not cause damage to the cultural relics. 2.

The temperature and humidity control showcase of the cultural relics showcase should be well sealing. The internal equipment should be installed with a equipment 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 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. 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 gel.

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. 3. Cultural relic show cabinet lighting requirements: cultural relic display cabinets are optimized, according to the source into natural light and artificial light.

The light of the museum display lighting and lighting design is mainly natural sunlight or light emitted by fluorescent lamps, tungsten wire lamps, etc. The museum showcases should be used to use the light source generated by inert gas. The light radiation can be divided into many areas according to the wavelength nature, including the wavelength of the visible light zone (400-750nm), the infrared light zone (›750 nm), the ultraviolet light zone (‹ ‹ 400 nm).

The light of different wavelengths has different energy. According to the experiment of the Dalian Hongfang Block Cultural Relics Showcase Production Company, the destruction of different nature of light on cultural relics is different. Infrared light contains more thermal energy, which will promote the temperature of the cultural relic meter to rise, the humidity decreases, and the cultural relics are warped and cracking.

Ultraviolet light mainly plays the role of optical and lighting, which can fade, cotton, paper, paper, lacquerware and other organic cultural relics fading, yellowing, crispy hair, decreased strength, etc. It can be said that any cultural relics composed of organic chemicals will occur under the illumination of light, which will lead to the deterioration of these objects. In addition, light to inorganic objects such as metal, stone, ceramics, etc.

also have a certain optical degradation and destruction, but it is slow and not easy to detect. The display of the light source museum's display is mainly natural light, artificial light and comprehensive light. The use of artificial light in display is generally considered to be completely controllable.

Generally speaking, general light sources suitable for museums include fluorescent lamps, incandescent lamps, metal halide lamps, etc. But choose the light source carefully, because many light sources are more or less red -light outer and purple light outer rays with different strengths. Therefore, in the display, the light source and lighting equipment can.

In recent years, the cold light source of lighting by optical fiber -optical fiber fiber lighting has begun to be widely used in display. Because of its unique lighting method and the advantages of ordinary lighting, due to its unique lighting method and the advantages of ordinary lighting, it is very suitable for display and display of exhibition cabinet display for full -closed artificial lighting. The biggest feature is that there is no infrared light and ultraviolet light radiation, non -conductive and non -heating, can guide light to various places, will not produce aging, long service life, convenient lighting system maintenance, etc.

The Shanghai Museum, the CPC First Convention Memorial Hall, the Shanghai Lu Xun Memorial Hall, and the Nanjing Museum are displayed in Dalian Light Guidance Fiber Play Cabinet, and achieved good results. The degree of illuminance is used to determine the amount of light illuminance of the object, and the unit is Lex (IUX). Lighting on cultural relics, the country's control degree is limited.

The standard for lighting and lighting of the museum display room is: the illuminance of calligraphy, calligraphy, literature books, silk hemp textile textiles and other cultural relics, the illuminance standard is ≤50 IUX. For light -sensitive lacquerware, oil paintings, leather and other cultural relics, the illumination standard is ≤150 IUX. For not sensitive iron, jade, ceramics, etc.

, the illumination standard ≤300 IUX. The annual exposure standard for light -sensitive cultural relics is 12000 IUX, and the degree of photos of 50 IUX average 300 days a day exposed 8 hours a day. The annual exposure standard for light sensitive cultural relics is 36000 IUX, and the timely exposure of 8 hours a year is exposed for 300 days.

The display equipment produced by the lighting safety of the lighting safety is that the showcases produced by them are independent cabinets set with 24V power lighting and transformers and cabinets from lamps. There are no fire hazards without fire hazards, no basic indicators do not have the standard of cultural Exhibition Cabinet. .
