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 moisture absorption effect of desiccants 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 desiccant testing method?
Wrong practice two: After taking out the sample, the customer directly poured a cup of water onto it to see Desiccant Does it absorb moisture quickly?
Firstly Desiccant is to absorb moisture from the air to achieve a relatively dry environment. Its main ability is to absorb moisture from the air, not liquid water. It is not a sponge; super absorbent resins are used to absorb liquid water. Therefore, directly pouring water onto the desiccant to test its moisture absorption effect is a wrong approach.
So why can some desiccants absorb water immediately? Desiccant Moisture absorption is divided into two types: physical absorption and chemical absorption. If the desiccant undergoes physical absorption (e.g., silica gel desiccant), it can quickly absorb some moisture. However, chemically absorbing desiccants (e.g., HMB desiccant) require a reaction time.
