According to research, moisture-regulating materials can be divided into five main categories

Research results show that moisture-regulating materials can be divided into five categories:
The first category is silica gel. Although it has moisture-regulating functions, it is not often used in moisture regulation because it often lags in the adsorption and circulation of water;
The second category is inorganic salts. During the process of absorbing moisture, it will deliquesce by itself, affecting the items in the space, so its use is also subject to certain limitations;
The third category is inorganic mineral materials, which mainly include diatomaceous earth, montmorillonite, bentonite, etc. These materials are not only low in cost but also have a strong ability to absorb moisture. They can be easily processed into various shapes for everyday use, making them one of the most commonly used moisture-regulating materials;
The fourth category is organic polymer materials, such as polyacrylic acid and polyvinyl alcohol. Although their adsorption is good, they are difficult to dehydrate;
The fifth category is composite moisture-regulating materials This has been gradually developed in recent years by combining different types of materials to achieve a moisture-regulating effect.
