Silica Gel Desiccant for home user is a variety of silica gel packaged in moisture-permeable pouches. The main raw material silica gel is a kind of hydrous silica with high microporous structure, non-toxic, tasteless, odorless, chemically stable, and has strong hygroscopic properties. , is a highly active adsorbent material. It is usually prepared by reacting sodium silicate and sulfuric acid, and undergoing a series of post-treatment processes such as aging and acid foaming. So, how does Silica Gel Desiccant for home user understand the misunderstandings of moisture content determination?

1. Put a small amount of Silica Gel Desiccant for home user into water, and observe the intensity of its explosion in contact with water: if the explosion is fast and the explosion effect is strong, it is considered that the product has low water content and good adsorption capacity.
In fact, the water explosion rate of Silica Gel Desiccant for home user has little relationship with the water content and adsorption capacity of silica gel. It cannot reflect the water absorption of the desiccant well, because the "explosion" is only instantaneous, while the level of water absorption is continuous. It has been proved that some manufacturers on the market have deliberately produced products with good "explosion rate" whose water content reaches or even exceeds 15%, while their adsorption capacity is far below the industry standard, which is completely unqualified. .

2. Take a small amount of Silica Gel Desiccant for home user and seal it with a small amount of discolored silica gel, and observe the discoloration speed of the discolored silica gel. The slow discoloration speed indicates that the water content of the product is low.
This detection method is relatively scientific, but it can only indicate whether the water content of the detected Silica Gel Desiccant for home user exceeds that of the color-changing silica gel. In addition, the discoloration silica gel produced by the respective manufacturers, due to the different proportions of the added raw materials, will also cause the discoloration silica gel itself to change color differently. Therefore, we are not completely convinced by this detection method.
