& nbsp; As the core carrier of cultural relics preservation and display, the sealing performance of museum display cabinet is directly related to the safety and life of cultural relics. In the complex and changeable natural environment, sealing is like building a "micro-environmental barrier" for cultural relics, isolating external pollution, temperature and humidity fluctuations and harmful light, providing a stable and safe preservation space for precious cultural heritage. From the four dimensions of material, structure, detection and environmental control, Huabo Art Exhibition systematically analyses the core requirements of the sealing of museum display cabinets. & nbsp; 1. Material selection: the basis for building high tightness: the tightness of the display cabinet first depends on the scientific selection of materials. The sealant strip shall be made of anti-aging and highly elastic silicone material, such as "O-type" silicone tube, whose tensile strength shall be ≥ 7.0 MPa and hardness shall be controlled within HA60 ± 5 to ensure no deformation under long-term pressure. Neutral ring sealant shall be used at the joint between glass and metal, which not only has high viscosity (7500-10000PS) and heat resistance (melting point & gt; 150 ℃), but also ensures that there is no acid volatile, so as to avoid secondary damage to cultural relics. The display cabinet plate should be made of inert materials to prevent chemical reactions with cultural relics and ensure the purity of the sealed environment from the source.
& nbsp; & nbsp; Huabo Art Exhibition has been deeply engaged in the design, customization, production and installation of exhibition cabinets for more than ten years, creating quality with ingenuity and leading the future with innovation. We focus on providing one-stop display cabinet solutions
