2. Because of the reticular structure of the polymer absorber itself and the special packaging method of the product, its heat absorption performance is not obvious and can be ignored in the whole absorption process.

3. The absorption process is similar to the dissolution process of solute, and the dissolution of solute includes two processes. One is that solute particles need to absorb heat when they diffuse in water, so as to lower the temperature of the solution. The second is that when solute particles and water molecules combine to form hydrated molecules or hydrated ions, heat will be released, which will increase the temperature of the solution. The water-soluble polymer absorber in this product contains a small amount of bound water, so in the process of water absorption and dehumidification, there is actually only the process of polymer diffusion into water, which is endothermic.
