CHINA SILICA GEL DESICCANT DINGXING MANUFACTURER
Silica gel is a granular form of sodium silicate which has the strong ability to adsorb water vapor molecules. Silica gel packets offer a cost-effective way to protect the products against moisture damage during the transportation and storage.Blue indicating silica gel packets contain semi-transparent substance known as cobalt. They are available in beads or in crystal structure which are used as an indicator for moisture absorption in various industrial applications. The beads or crystals turn into dark blue color when silica gel releases the moisture, whereas light blue color indicates that the beads or crystals have adsorbed the moisture. The pink color beads or crystals mean that the silica gel needs to be regenerated or restored. Due to the strong adsorption capacity at low relative humidity, blue indicating silica gel packets are widely used in various fields for the drying process. This gel can be combined with non-indicating standard silica gel that comes in white color for ...
