So what is a desiccant bag?
The desiccant bags commonly used in our daily life are chemical desiccants containing calcium sulfate or calcium chloride and physical desiccants containing activated alumina or silica gel.
These desiccants use a static drying method in the product, that is, desiccant bags containing these desiccants are placed in packages containing electronic equipment, food, medicine, shoes and other products.
How does the desiccant in the desiccant bag work?
After sealing, the desiccant will absorb the moisture in the packaging to avoid rapid reproduction of microorganisms or rapid oxidation of metals due to high humidity environment, thus reducing product deterioration.
Desiccant can combine with water molecules in the air to achieve hygroscopic and moisture-proof properties. In closed environments such as food packaging, shoe boxes, desiccant can combine with water molecules to reduce the humidity in this “small environment”.
Different desiccants have different drying principles. For example, calcium chloride desiccant relies on the combination of calcium chloride and water molecules to form a gel-like substance.
Therefore, even at relatively high temperatures, chlorine reacts with calcium oxide water molecules and will not decompose to release absorbed water molecules. It seems that the effect of calcium chloride desiccant is relatively stable.
Another common desiccant is silica gel desiccant, which is prepared by reacting sodium silicate and sulfuric acid, then undergoing a series of treatments including acidification. This desiccant usually appears as small transparent spheres.
After absorbing moisture from the air into the mesh gaps inside, its color will change to pink, blue, purple and other colors. After drying at high temperature, it will turn into a colorless and transparent substance, which can be used repeatedly.
Things to note when using desiccant bags
Desiccant bags in some foods, medicines, clothes, shoes and other products can be reused by us and can be used for short-term drying and dehumidification of the same items in small storage spaces.
However, desiccants are often overlooked due to the small packaging size. Therefore, pay more attention to avoid serious consequences if children accidentally eat them.
For relatively large desiccants, some packages say that they cannot be placed in water. Because they contain some strong alkalis, they may explode and cause skin burns when placed in water. Therefore, everyone should pay attention to the safe handling of desiccants.
In short, desiccant has brought many benefits to life, but we should still pay attention to its safety to avoid harming ourselves and our families./.
