Properties: blue color silica gel into the blue gel indicator, allochroic silica gel and blue glue, appearance is blue or light blue glass particles, according to the particle shape can be divided into two spherical and patches, has itself after moisture absorption characteristics of the color change from blue to red.
Purpose:
1. Mainly used in instruments, meters, equipment in an airtight conditions such as moisture absorption rust, at the same time can through its color from blue to red after moisture absorption intuitive indicates the environmental relative humidity.
2. Used with ordinary silica gel desiccant, indicates the degree of moisture absorption desiccant and determine the relative humidity environment.
3. As for wrapping silica gel desiccant, widely used in precision instruments, leather, shoes, clothing, food, medicines and household appliances, etc.
Specification: 1-3mm; 2-4mm; 2-5mm; 4-8mm
