Many customers will immediately test the moisture absorption effect of the desiccant when they receive the humidity absorber refill sample. However, it is found that the moisture absorption effect of the desiccant is far from what we promised. Is there a problem with the moisture absorption effect of the desiccant, or is there a problem with the customer's testing method for humidity absorber refill?

Wrong practice one:

Many customers say that the humidity absorber refill is hygroscopic, so just throw it in the water and see if it is full after a few hours.

Humidity absorber refill maintains the space desiccant by absorbing moisture (moisture) in the air. Usually, the target of the desiccant is water vapor instead of liquid water, and the target object is not selected correctly.

High-quality humidity absorber refills will use waterproof and breathable packaging materials, because the desiccant absorbs water vapor in the air rather than liquid water. If the desiccant is directly thrown into the water, under the action of liquid water, the water should be an impermeable waterproof and breathable packaging material, otherwise the water can enter and reversely seep out (similar to a sponge), thus losing the desiccant itself. Moisture absorption and anti-reverse osmosis effect.

After the humidity absorber refill absorbs moisture, 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 directly throwing the desiccant into the water and soaking it is wrong.

Wrong practice two:

After the customer took out the sample, he directly poured a glass of water on it to see if the humidity absorber refill quickly absorbed moisture? The desiccant absorbs the moisture in the air to make the environment relatively dry. The main ability is to absorb the moisture in the air instead of liquid moisture. It is not a sponge. Superabsorbent resins (commonly used in baby diapers) are used to absorb liquid water, so it is a wrong practice to directly pour water on the desiccant to test the moisture absorption effect.
