There are many kinds of Moisture Absorber: food, pharmaceutical, industrial, container, etc. Different desiccant ingredients are also different. So, what kind of desiccant will explode in contact with water?

This is a kind of food Moisture Absorber, called calcium oxide desiccant (quicklime). Its raw material is the well-known quicklime. Everyone knows that quicklime heats up and expands when it meets water, generating a lot of heat instantly. In sufficient conditions, the desiccant may explode if it meets with water; if the conditions are not sufficient, it may also be dangerous (splashing on the eyes, skin will be burned).

The main component of Quicklime Moisture Absorber is calcium oxide. When calcium oxide encounters water, it will produce a sharp chemical reaction, releasing a lot of heat instantly. If the amount of lime in the bottle is relatively large, the heat generated by the chemical reaction will cause the bottle to expand rapidly, and the bottle will burst in severe cases. If the amount is small or the cap is not tightly closed, the lime may cause the plastic bottle to become hot and deformed.

Therefore, not all Moisture Absorbers will explode when exposed to water. Even the quicklime desiccant needs at least two conditions: placing the desiccant in a confined space and fully swelling with water. When everyone is in contact with the desiccant, don't worry about it exploding. First determine if it is

Quicklime Moisture Absorber, the method is very simple, observe its shape and color. The desiccants that we often come into contact with are food desiccants. There are three common food desiccants: silica gel desiccant (transparent particles), lime desiccant (white block), and mineral desiccant (brown round beads). Except for lime desiccant, the other two are non-toxic and environmentally friendly.
