The silica gel desiccant needs to be used within the validity period. If it exceeds the shelf life, it needs to be thrown away. However, many people do not know how to deal with this desiccant, and they ca n’t throw it away.
Silica gel desiccant refers to substances that can remove moisture in moist substances, such as calcium sulfate and calcium chloride, etc., and is dried by combining with water to form hydrates; physical desiccants, such as silica gel and activated alumina, are dried by physically adsorbing water .
If you want to deal with desiccant, you must first know what your desiccant is made of. Silica gel desiccant is also montmorillonite clay desiccant, calcium chloride, minerals, and some fiber desiccants, etc. Some desiccants react with air at room temperature after being discarded. The products are environmentally friendly, no secondary pollution, and some desiccants The storage time is very long and it is not easy to react or the reaction products will pollute the environment. This depends on what desiccant raw materials can make a specific treatment plan.
The characteristics of the silica gel desiccant determine that it can be reused. Therefore, the method of treating the silica gel desiccant is to contact the company that recycles the silica gel desiccant. They have special equipment for the reuse process, which can restore the moisture absorption of the silica gel desiccant. ability. Of course, the moisture absorption rate of the silica gel desiccant for secondary use is certainly not as high as that of the new materials. Therefore, if you buy a silica gel desiccant, you still have to choose a regular large factory. . Only the silica gel desiccant produced by the new material can achieve your required moisture absorption rate.
