Properties
Blue silica gel is divided into blue gel indicator, color'changed silicagel and blue gel, and the appearance is blue or light blue glassy particle. According to the shape of particles, it can be divided into lumpy type and spherical type, and it also can change into red from the blue color after the absorption of moisture.
Application
1. It is mainly used for antirust and moisture absorption of instruments and equipment and so on, at the same time, it can indicate relative humidity environment through the direct indicator of which blue color turn into red color after the absorption of moisture. 2. With combination of the ordinary silica gel desiccant, it is usedto indicate the moisture absorption of desiccant and to determine the extent and relative humidity of the environment. AS the silicagel desiccant of packaging, it is widely used in precise instruments, leather, shoes, clothing, food, medicines and household appliances.
