Many customers immediately test the moisture absorption effect of the desiccant upon receiving the sample. However, they find 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?
Many clients immediately test the desiccant sample upon receipt. Desiccant However, they find that the desiccant's moisture absorption effect is far from what we promised. Is there a problem with the desiccant's moisture absorption effect, or is there a problem with the client's testing method?
Incorrect method 1: Many clients say that desiccants absorb moisture, so they can be directly thrown into water, and after a few hours, see if they have absorbed enough water.
First, desiccants achieve their purpose of maintaining space by absorbing moisture (dampness) from the air. Desiccant The usual working environment for desiccants is not liquid water; the target object is incorrect.
Second, high-quality desiccants use waterproof and breathable packaging materials because desiccants absorb water vapor from the air, not liquid water. If the desiccant is directly thrown into water, under the action of liquid water, the water should not be able to penetrate the waterproof and breathable packaging material; otherwise, if water can enter, it can also seep out (similar to a sponge), thus losing the desiccant's inherent moisture absorption and anti-seepage function.
Third, after the desiccant absorbs moisture, Desiccant the moisture should be adsorbed inside, and there should be no water on the surface. If you take out the desiccant that has been soaked in water, it will definitely drip water. This also shows that the testing method of directly soaking the desiccant in water to absorb moisture is incorrect.
