A museum is a history of materialized development. Cultural relic collections are the necessary material conditions for museum exhibition narratives, carrying persuasive and infectious information. The exhibition narrative is inseparable from the cultural relic collection. Through the cultural relic collection, the audience can travel through time and space and have a dialogue with history. In order to protect the collection of cultural relics from damage and enable it to fulfill its mission of inheriting and promoting traditional culture in the new era, as the guardian of cultural relics, museum showcases have strict technical specifications in the design and production. Among them, environmental protection performance is one of the indispensable basic indicators, which will be communicated and discussed later.
1. The necessity of environmental protection performance of museum showcases
When cultural relics enter the museum, the environment of the museum directly affects the "life span" of the cultural relics. The harmful gases in the museum not only come from the outside atmosphere, but also come from the corrosive gases that can be released by the exhibition materials, showcases and decorative materials in the museum body.
Among them, the showcases and the exhibition materials inside them will be in direct contact with cultural relics. If they are made of raw materials containing acidic components such as chlorine and sulfur, after long-term contact with the air or the materials age, the showcases will release harmful gases, including Sulfur dioxide, hydrogen sulfide, volatile organic acids, etc. can cause unpredictable damage to culture. As the "home" of cultural relics, museum exhibition halls must first ensure their own environmental protection performance in order to create a safe and comfortable micro-environment for "exhibition" and "hiding" of cultural relics.
Not only that, the exhibition space inside the museum is relatively closed, the ventilation is weak, and the harmful gases released by the exhibition cabinets with unqualified environmental protection quality cannot be discharged in time, which will also cause harm to the health of the visitors.
2. Technical standards for environmental performance of museum showcases
As a leader in customized showcase manufacturing, DG Display Showcase is committed to providing fully customized showcase production services for various exhibition halls. Here we would like to share with you some of Boxin showcase manufacturing experience.
First of all, all raw materials for making showcases must be inert and environmentally friendly materials that will not have any chemical reaction with the cultural relics inside the cabinet. Avoid the use of wood, paint, leather, chemical fiber textiles and other materials that may cause potential harm to cultural relics. Therefore, Boxin showcases have an overall metal structure, using aluminum alloy profiles and facing metal sheets to improve the environmental safety of showcase materials.
During the showcase production process, the metal plates are painted using electrostatic spraying to reduce the amount of thinner used, reduce the paint odor, and make the painting process greener and more environmentally friendly. At the same time, the fabrics inside the cabinet should be environmentally friendly cotton and linen fabrics, and should be fixed on the board using glue-free bonding. Only by starting from the source of the environmental protection performance of cultural relic showcases, with careful attention to materials, strict selection of materials, standardized processes, and intelligent production can we create a safe and comfortable display space for cultural relics and effectively play the role of "first-level protection".
