Common Mistakes in Desiccant Testing (2)

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 customers immediately test the desiccant's moisture absorption effect upon receiving samples. 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 customer's test method for the desiccant?
Incorrect practice two: After the customer took out the sample, they directly poured a cup of water on it, to see Desiccant whether it absorbs moisture quickly?
Firstly Desiccant absorbs moisture from the air to achieve a relatively dry environment. Its main ability is to absorb moisture from the air, not liquid water. It's not a sponge; superabsorbent polymers are used to absorb liquid water, so pouring water directly onto a desiccant to test its moisture absorption effect is an incorrect practice.
So why can some desiccants absorb moisture immediately? Desiccant Moisture absorption is divided into two types: physical absorption and chemical absorption. If the desiccant is physically absorbent (e.g., silica gel desiccant), it can quickly absorb some moisture, but chemically absorbent desiccants (e.g., Haibaobao desiccant) require a reaction time.
