The preventive protection of cultural relics has become an important part of the development of the industry. Through effective quality management, monitoring, evaluation, regulation and intervention, the harmful effects of various environmental factors on the collections are restrained, and cultural relics are in a "stable and clean" safe survival The environment prevents or delays the deterioration of precious cultural relics and achieves the purpose of long-term preservation of cultural relics. The preventive protection in the exhibition hall is mainly based on the micro-environment humidity control of the cultural relics exhibition cabinet. Therefore, preventive protection in the exhibition hall has two key factors: microenvironment and humidity control. Due to the widespread problem of glass bending in the practical process, it is difficult to guarantee the airtightness of cultural relics showcases and storage cabinets.
In response to this problem, on August 23, the " Preventive Protection of Chinese Object Showcase Glass Safety Risk Assessment Meeting " was held in Beijing. Cultural and cultural experts and representatives of related companies have commented on the widespread failure of the sealing of museum showcases; various factors that cause failure (glass bending is a very important factor); the relationship between glass bending and showcase sealing; feasibility demonstration of low bending resistance, etc. Four issues were discussed.
What problem does the “bending resistance and low reaction” solve in the museum?
Research shows that there are many problems in the application of museum showcase glass: most museum showcases will have gaps due to external force or self-weight, and the sealing performance will gradually fail. The larger the glass area, the more serious the bending. The micro-environment of the cultural relics showcase is greatly threatened.
In the exhibition hall, there are two key factors for the preventive protection of cultural relics: micro-environment formation and humidity control. When there are gaps in the showcase glass to varying degrees and the microenvironment cannot be formed, how can preventive protection start?
Regarding this issue, Bo Mingtang launched "Bending-resistant low-reflection laminated glass". It is a new generation of museum showcase glass. The introduction of this product can greatly improve the sealing condition of the showcase and play a role in maintaining the micro-environment in the cabinet.
Zhang Yutang, chief engineer of Beijing Bomingtang Glass Co., Ltd. introduced: In the process of product development, it has united with multiple third-party inspection agencies such as China Building Materials Inspection and Verification Group to repeatedly conduct a large number of verification experiments to resist bending. The performance of anti-display and protection has been verified. The anti-bending and low-reflection has the five characteristics of "bending resistance, flatter", "non-reflective, clear", "tear resistance, safer", "non-yellowing, more durable", and "corrosion-resistant, more stable".
Miao Xiaogang, deputy general manager of Beijing Bomingtang Glass Co., Ltd., introduced the museums that have applied anti-bending and low-reflection: Zhoukoudian Peking Man Site Museum, Hunan Provincial Museum, Shanghai Suning Art Museum, Liangzhu Museum, Song Qingling Former Residence Memorial Museum Chinese People’s Revolution Military Museum, National Oceanographic Museum, Lushun Museum, Erlitou Xiadu Site Museum, Zhejiang University Art and Archaeology Museum, Changzhou Art Museum, Keyuan Museum, Anhui Art Museum , etc. Anti-bending and low anti-reflection have achieved very good application effects in these museums, and the display and protection of cultural relics have been improved.
Preventive protection must have requirements for showcase glass
Experts at the meeting said that the application of low bending resistance to museums with conditions, in addition to better display effects, can also solve When the preventive protection of cultural relics is a problem, products should be promoted, and at the same time, we should continue to dig into the technical advantages of bending resistance and low reflection, so that more units can realize the benefits of bending resistance and low reflection; museum showcase glass should start from a technical point of view and from scientific research In-depth perspectives, sharing with industry cultural protection experts from a professional perspective, and conducting more in-depth exchanges on preventive protection issues.

Experts suggest to promote the formulation of relevant standards
With the rapid development of cultural and museum undertakings, museum construction Facing a large number of new museum construction and old museum renovation. As an important part of the exhibition cabinet, the museum showcase glass acts as a window for the “collection” to communicate with the audience. Its role is obvious, but how to choose to meet the museum standardsThe showcase glass has become a common problem faced by museums.
It is understood that the museum showcase glass still lacks corresponding national standards. In 2019, in the group standard setting project led by the cultural relics protection equipment industrialization and application collaborative work platform, Bo Mingtang, as the creator of this category, presided over the formulation of the group standard for museum showcase glass and moved towards the industry standard. Experts also suggest that Bo Mingtang and other companies participate more in the formulation of relevant standards in the industry, strengthen communication and dialogue, and break down the barriers between the participating links in the preventive protection of cultural relics. Let the showcase glass help preventive protection of cultural relics. I believe that in the future, as people pay more attention to cultural relics, relevant national standards will be introduced one after another, helping the cultural and museum industry to a higher level.
