The secret that silica gel desiccant can also be turned into treasure
We will see desiccant bags in the package of many drugs and snacks, and there are generally such cautions as "do not eat" and "please discard" printed on them. In fact, there are two kinds of desiccants commonly used now, namely lime desiccant and silica gel desiccant. The price of lime desiccant is low, and in recent years, there have been many news about children accidentally eating or playing with water explosion. From the safety point of view, silica gel desiccant is more suitable.
Difference between mineral desiccant and silica gel desiccant
Mineral desiccant-Mineral desiccant is composed of several kinds of natural minerals, with the appearance of small gray-white balls. It is harmless and is an environmentally friendly desiccant that can be degraded. Silica desiccant- The main component is silica, which is granular or bead-like from natural minerals after purification and processing. As a desiccant, its microporous structure has good affinity to water molecules. The suitable environment of silica gel for moisture absorption is room temperature (20~32) and high humidity (60~90%), and it can reduce the relative humidity of the environment to about 40%. Silica gel is a highly reactive adsorbent material, usually made by the reaction of sodium silicate and sulfuric acid and by physical processes such as aging and acid bubbling
