Problems solved by technology

Although silica gel is an effective humidity control material, its application is greatly limited due to its serious hysteresis in the water adsorption and desorption cycle; although inorganic salt humidity control materials can Salt saturated solution is used to maintain the humidity of the space, but since most solid inorganic salts will slowly deliquesce with the increase of moisture absorption, and are unstable at room temperature, salting out is very easy to occur, and it will become more and more serious with the extension of time, thus It pollutes the space for storing items, which limits its application; although inorganic mineral humidity-controlling materials have many internal pores, large specific surface area, and strong adsorption capacity, their wet capacity is small, which limits their application. Restrictions: Although organic moisture-controlling materials have a large amount of moisture absorption and a fast moisture absorption rate, their application

Description

technical field [0001] The invention relates to a composite humidity control material, which belongs to the technical field of humidity control materials. Background technique [0002] Air humidity not only has an important impact on air quality, human health and the storage of items, but also plays an important role in energy saving and emission reduction. This is because the air humidity ranges from 40% to 60%, the number of bacteria and viruses is the least, and the possibility of various diseases and various chemical effects harmful to humans is the lowest. At the same time, air humidity can measure the degree of active humidity adjustment. energy consumption. However, active humidity adjustment consumes artificial energy, pollutes the environment and destroys the ecology, and is not in line with the sustainable development strategy. [0003] In order to comply with the strategy of sustainable development, people have found: a passive ecological method to regulate humi...
