BLUE SILICAGEL
- Blue silica gel is a kind of blue silica gel, with a size of 0.2 - 0.5 cm. Blue silica is essentially the same chemical formula as regular silicon silica granules, but the manufacturer has dipped it in a color indicator called Cobalt Chloride, so it has a characteristic blue color.
- The applications of green silicagel in life are: as a catalyst in the synthesis of petrochemicals, water filtration, desiccant, drying of food products, pharmaceuticals, electronics ... but when moisture will have pink. This helps us identify whether the silica gel is saturated with water, when the silica gel has turned pink, meaning it is no longer able to absorb moisture.
- However, it can be recycled for reuse by drying in a microwave oven, at which time the Cobalt Chloride molecules will dehydrate the crystals and return to blue for reuse.
- Blue silicagel beads are often used to dehumidify laboratories, transformers, cameras, jewelry, etc.
