spheric silica gel chromatographi laboratory granule silica gel for dessicator desiccant polymer pouch
Introduction:
Silica Gel is conventional desiccant, available in porous, granular, and amorphous form chemical reaction between Sulfuric acid and Sodium Silicate. The internal structure of Silica Gel is composed of a vast network of interconnected microscopic pores which attract and hold water, alcohol, hydrocarbons, and other chemicals by the phenomena known as physical adsorption and capillary condensation. Except for the blue indicated gel contains of cobalt chloride, the white silica gel can consider as a food grade products. It generally uses for various products such as auto/spare parts, electrical appliances, electronics, food packing, furniture, footwear, pharmaceutical and nutraceutical, etc.
