The purpose of using a constant humidity machine in a museum showcase is to maintain a constant humidity environment inside the showcase to ensure the safety and integrity of the exhibits. 1. Why is a constant humidity environment needed? Constant humidity environment means that the humidity inside the showcase is maintained at a relatively stable level. In museums, many cultural relics and artworks are very sensitive to humidity because they are usually composed of various materials, such as wood, paper, fabric, metal, etc., which are all very sensitive to changes in humidity. If the humidity inside the showcase is too high or too low, it will cause varying degrees of damage to the exhibits. For example, too high humidity can cause problems such as wood swelling, paper yellowing and mildew, and metal rust; while too low humidity can cause wood shrinkage, paper dryness and fragmentation, and fabric hardening. Therefore, to protect exhibits, museums need to maintain a constant humidity environment. 2. The role of the constant humidity machine The constant humidity machine is a professional device that can automatically adjust the humidity inside the display cabinet to maintain a constant humidity level by controlling the feedback signal from the humidity sensor. In museum display cases, the humidifier is usually installed at the bottom or top of the display case and connected to the water tank or water pipe inside the display case. The constant humidity machine automatically adjusts the speed of humidification or dehumidification according to the humidity changes inside the showcase to maintain constant humidity. The advantage of the constant humidity machine is that it can accurately control the humidity inside the display cabinet, and can automatically adjust the speed of humidification or dehumidification to cope with different humidity changes. In addition, the constant humidity machine also has the advantages of energy saving, safety, reliability, etc., and can work stably for a long time. 3. Selection of constant humidity machine When choosing a constant humidity machine, you need to consider the following aspects: The power and capacity of the constant humidity machine should match the size of the display cabinet and the number of exhibits to ensure that the constant humidity machine can effectively control the interior of the display cabinet. of humidity. The humidifier should humidify or dehumidify quickly enough to cope with changes in humidity. At the same time, the constant humidity machine should have automatic drainage and water level protection functions to ensure that the water tank will not overflow or the water pipe will not be blocked. In addition, the types of exhibits in museum showcases are also diverse, including paper, cloth, wood, metal and other materials, and these materials have different requirements for humidity. For example, paper will be damaged in an environment with too high or too low humidity. High humidity will make the paper soft and wrinkle easily, while low humidity will make the paper fragile and brittle; for wood products, too high humidity will cause the paper to become soft and wrinkle easily. High humidity can easily lead to rot and mildew, while too low humidity can cause wood products to dry out and deform. Therefore, the constant humidity machine in the museum showcase can not only control the humidity in the showcase, but also adjust it for exhibits of different materials to achieve the best preservation effect and protect the integrity and long-term preservation of precious cultural relics. In addition, the constant humidity machine can also prevent the growth of mold and bacteria in the display cabinets, avoid secondary contamination of the exhibits, and improve the safety and hygiene of the exhibition. In general, the constant humidity machine in the museum display cabinet not only protects and preserves the exhibits, but also considers the health and comfort of the audience. The constant humidity machine can control the ambient humidity in the exhibition cabinet, provide visitors with a safe and comfortable exhibition environment, and protect their health. To sum up, the constant humidity machine in the museum showcase is a very necessary equipment, which can effectively protect the exhibits, improve the safety and hygiene of the exhibition, and provide a high-quality exhibition environment for the audience.
