Fine Pored White Silica Gel
Fine pored silica gel which is produced in our company is widely used in dehydration and epuration of industrial gas, liquid phase and desiccant. It can also be used as catalyst and catalyst carrier.
silica Gel is a substance used as desiccant, when the beads take up moisture the color will turn tight blue.
Silica gel, composed of solid micro-porous silica beads, are typically used as a
desiccant. The numerous, interlocking pores on the beads work by creating a lower vapor pressure than the surrounding air, causing the water molecules in the surrounding air adhere to the silica beads.
Nature :
blue or light blue or small spherical particles that do not dissolve in water. Easy to absorb moisture and will gradually be transformed into pink. Moisture can use the color change direction and humidity. For industrial and household desiccant moisture.
