Container desiccant is also called strong desiccant and biochemical desiccant. It is mainly used in shipping containers. We can appropriately use some methods to test the effect:

1. The desiccant absorbs moisture in the air to make the environment relatively dry. The main ability is to absorb moisture in the air instead of liquid moisture. Therefore, it is a wrong practice to directly pour the moisture on the desiccant to test the moisture absorption effect. .

2. After moisture absorption, the moisture should be absorbed in the desiccant, and there should be no moisture on the surface. If you take out the desiccant soaked in water, it will definitely drip. This also shows that the test method of throwing the desiccant directly into water to soak in moisture absorption is wrong.

3. If the desiccant is directly thrown into the water, the water should be an impermeable, waterproof and breathable packaging material under the action of liquid water, otherwise the water can enter but also can reverse ooze out, thus losing the moisture absorption and anti-reverse effect of the desiccant itself. Infiltration.

4. The desiccant maintains the space by absorbing moisture in the air. The good ones will use waterproof and breathable packaging materials. The working environment is not liquid water, because the desiccant absorbs water vapor in the air instead of liquid water.

Container desiccant has a wide range of applications in the maritime field. The reason for our effect test is to ensure that the desiccant can be used in a closed space, so as to absorb the moisture in the incoming outside air without affecting its use.
