The museum is the place where the cultural relics protection collection and display are displayed, because the cultural relics are unspeakable resources, and some cultural relics have a history of hundreds of thousands of years. In this long time, there will be such damage. Some may be natural reasons, some It may be artificial, so that some cultural relics are very fragile today, and it is easily damaged.
For example, Ma Wangdui lacquer (xǐ) yarn crown. Since the unearthed in the 1980s, archeologists have brought oxidation reactions in order to avoid its long -term exposure to light and air. The right protection is sealed in the original box, controlled the temperature and humidity, and it is strictly forbidden to display it outside.
From this aspect, we can also understand how important the humidity is to keep the cultural relics of the museum. As for organic cultural relics, some cultural relics will be too low due to dryness. Mold is a big problem; for inorganic cultural relics, if the wet transition is too high, the golden stone cultural relics will rust, and the ceramic cultural relics are easy to crack off.
The unexpected harm is based on the relative humidity of the "Museum Collection Storage Environment Trial Standard" museum issued by the State Cultural Relics Bureau. The cultural relics of different material varieties also have different temperature and humidity requests. Some special cultural relics need to set the humidity separately.
In the museum, the following methods are generally adopted to control temperature and humidity: ① Macro system control: mainly rely on the central air -conditioning system to control the temperature and humidity of the museum. However, because the scope of central air -conditioning control is larger, it is affected by the exhibition hall environment, visits to the traffic, and the external atmospheric environment. It is often difficult to accurately control.
② Microcycles control: The micro -environment in the museum showcase directly affects the life of the museum exhibits. To enhance the closedness of the museum showcase, because a well -sealed museum showcase can provide a relatively stable humidity condition for cultural relics storage. However, it is basically not enough, so the demand is equipped with a constant humidity system in the exhibition cabinet of important collections.
Set the humidity range of this cultural relic. When the humidity exceeds the request range, the humidity controller can automatically turn on the dehumidifier to reduce the humidity to make it make it make it make it make it make it make it make it make it make it. Better custody.
