How to use and preserve silica gel desiccant

The working principle of silica gel desiccant mainly depends on adsorption to remove water molecules from wet substances, that is, it is adsorbed on the surface of solid substances by mutual attraction between particles on the solid surface and water molecules in various gases and liquids. Silica gel desiccant has many pores and huge surface area.


For the use of silica gel desiccant, first calculate the space you need to use, the water vapor transmittance of the packaging material, the days you want to guarantee quality, the relative humidity and temperature, and then get the appropriate dosage. When using, directly place the silica gel desiccant in the product package you want to prevent moisture. Note that it must be sealed after placement, Otherwise, silica gel desiccant can't absorb a steady stream of moisture.
