Blue silica gel has the adsorption and moisture-proof effect of fine-porous silica gel. Its characteristic is that during the moisture absorption process, it can turn purple and then light red as the amount of moisture absorbed increases. It can indicate the humidity of the environment and whether it needs to be replaced with new silica gel or reused.
Blue Silica Gel can be used alone to absorb moisture. What are the characteristics of blue silica gel that changes color after drying? It is usually combined with ordinary silica gel desiccant to reduce the degree of moisture absorption of JJTJE7 wood agent, so as to determine the relative humidity of the environment.
Blue Silica Gel is widely used for moisture-proof packaging of precision instruments, leather, clothing, food and household appliances.
