Blue silica gel

Character：
Blue silica gel has the adsorption and moisture-proof effect of narrow pore silica gel, It is characterized by the moisture absorption process, it can become Light blue with the increase of moisture absorption, and finally become light red or light pink. It can indicate the humidity of the environment and also visually show whether a new desiccant needs to be replaced.

Use：
Blue silica gel is widely used in respirators, transformers, electrical cabinets, precision instruments, leather, clothing, household appliances packaging moisture-proof, can be used as a desiccant alone, can also be used with fine silica gel.
Blue silica gel has the adsorption and moisture-proof effect of fine porous silica gel, which is characterized by the moisture absorption process, can become purple with the increase of moisture absorption, and then become light red. Can indicate the humidity of the environment can also be intuitive whether the need to replace the new silicone or reuse.
Blue silica gel can be used alone for hygroscopic moisture absorption, because of the characteristics of discoloration, it is usually used with ordinary silica gel desiccant, used to indicate the degree of hygroscopic desiccant, in order to determine the relative humidity of the environment.
