Museums are places where important cultural relics are preserved and treasured. The temperature and humidity are the most influential factors among the cultural relics in museums. These factors will directly cause all physical, chemical and biological effects.
Generally speaking, as a single factor, the influence of air gradient in museums on cultural relics is not very obvious. However, because of the simultaneous existence of light and various gases in the environment, when the cultural relics in museums are affected by these factors, the certain chemical reactions will take place, and the temperature plays an accelerating role in the subsequent reactions. In addition, it should be noticed that the change of temperature will also cause the change of relative humidity, which will have an impact on cultural relics. Compared with temperature, humidity has a more obvious impact on cultural relics. The change of relative humidity has different effects on the preservation of many cultural relics in the library. At this time, the museum must use temperature recorder to measure and record the temperature and humidity of the cultural relics in the collection at any time, so as to avoid the damage to the important cultural relics.
When the humidity in the air of museums is high, they are easy to absorb water, causing hydrolysis, weight gain, volume expansion and other phenomena. When the humidity in the air is low, the cultural relics will release internal moisture and produce shrinkage and cracking. Different cultural relics have different reactions to relative humidity. That silk, wool, cotton, hemp, paper and bamboo and wood of animal and plant fiber materials are sensitive to humidity, especially silk fabrics and books. Therefore, the paperless temperature recorder can record and detect the temperature and humidity of indoor cultural relics at this time. When the special situation is slightly obvious, the staff members can record and detect the temperature and humidity of indoor cultural relics. Deployment can be made as soon as possible.
Although monitoring the temperature and humidity of the museum is a very arduous task, as long as the size of the museum is used to determine the number of points to be taken and the multi-channel temperature recorder is placed in a reasonable position, the temperature and humidity recorder records the temperature and humidity of the museum space from time to time according to the requirements set by the staff. The staff can copy the temperature data recorder with USB pen driver every day. The data can be analyzed and printed on the computer for archiving. Of course, it can also be used with the temperature and humidity control and adjustment equipment of the museum. When the required conditions are not met, the information is sent to the adjustment equipment, so that the range of temperature and humidity in the museum can be maintained in a reasonable range.
