With the improvement of industry and living standards, humidity has become an important issue for the preservation and transportation of many products. In order to solve the problems caused by humidity, desiccants came into being. As a common desiccant, colored silica gel desiccant occupies an important position in the product line.


The function and principle of colored silica gel desiccant


Colored silica gel desiccant is a hygroscopic agent, mainly used to absorb and control the humidity in the environment. It consists of silica gel and some kind of indicator, a common indicator is blue which changes from blue to pink. When the desiccant absorbs moisture and is saturated, the color of the indicator changes. By observing the color change, we can judge the level of environmental humidity. The hygroscopic principle of colored silica gel desiccant is mainly physical adsorption. The surface of silica gel has many tiny pores, which can absorb water molecules and reduce the humidity to a controllable range. When the humidity is high, silica gel absorbs moisture from the air and locks it in the pores, keeping the surrounding environment dry.
