The Importance of Constant Temperature and Humidity Machines for Museum Display Cabinets
Museum is a place for collection and display of cultural relics, cultural relics are non-reproducible resources with significant historical and cultural value. The use of science and technology, so that cultural relics have a stable collection environment, for cultural relics, is very important.
Some cultural relics have hundreds to tens of millions of years of history, in this long years, there are different degrees of natural or man-made damage, some even destroyed. With the development of society, the museum collection, display of cultural relics not only to meet the audience of cultural relics viewing requirements, but also to consider the storage environment of cultural relics of the destruction of the role, so stable, reasonable, scientific storage environment, is the museum of cultural relics in the maintenance of a very important part of the work.
Museum display cabinet is an important carrier of cultural relics collection and display, display space internal temperature and humidity environment quality, the value of the collection of cultural relics has a very direct impact. According to the new collection requirements, constant temperature and humidity environment is very important for cultural relics collection. Therefore, more and more museums are choosing to use the display cabinet constant temperature and humidity machine to protect cultural relics.
Temperature and humidity on the museum of cultural relics custody has a very important impact on organic cultural relics, humidity is too low, some cultural relics will be warped due to drying and cracking and other problems, humidity is too high, insects, mould is a big problem, the temperature is too high or too low, the organic cultural relics to bring about greater damage; on the inorganic cultural relics, humidity is too high, gold and stone cultural relics will be rusted, and ceramic cultural relics are easy to cracking and flaking, so the control of good humidity change will extend the life of cultural relics. Good changes in humidity will extend the life of cultural relics, on the contrary, let it change will form an unexpected harm according to the State Administration of Cultural Heritage issued the "Museum Collection Storage Environment Trial Standards" museum of relative humidity in 45% to 60%, the temperature of 18-22 ℃, it will be comparable to the ideal. And different material varieties of cultural relics on the temperature and humidity requirements are not the same, some cultural relics to set the temperature and humidity alone.
In the museum generally take the following approach to control temperature and humidity:
① macro system control: mainly relying on the air conditioning system to control the temperature and humidity of the museum. However, due to the air conditioning control range is relatively large, by the environment of the exhibition hall, the flow of visitors, as well as the influence of the external atmospheric environment, it is often difficult to accurately control.
② display cabinets constant temperature and humidity control: museum display cabinets constant temperature and humidity is the protection of cultural relics "guardian angel", to ensure that the collection of cultural relics are not destroyed. The micro-environment within the museum cabinet directly affects the life of the museum exhibits. To enhance the closeness of the museum cabinet, due to a good sealing of the museum cabinet can provide a relatively stable humidity conditions for the custody of cultural relics. But single just so basic is not enough, so the demand in the important collection of exhibition cabinet device constant temperature and humidity system, set this kind of cultural relics of temperature and humidity range, when the temperature and humidity over the request range, temperature and humidity control instrument can automatically open the adjustment function, so that the good custody.
