سیلیکاژل آبی (گرانول | پرک )

Silica Gel is non-corrosive, odourless, non-toxic and chemically inert. It has a very strong affinity for water and will absorb it. The main component of silica gel is Silicon Dioxide; it is a granular, vitreous, highly porous form of Silica made synthetically from Sodium Silicate and Sulfuric acid under controlled conditions. After it is washed, aged and dried granular and beaded shapes are formed. The beaded form has a higher mechanical strength, therefore does not generate dust, the uniform size reduces gas flow channeling and minimize the pressure drop. Silica gel can absorb water up to 30% or more of its own weight. Silica Gel can be regenerated for re-use by heating at 120 C. We offer a qualitative range of silica gel in granular and beaded form as below:

Blue indicating Silica Gel

This type of silica gel is made by the chemical combination of silica gel and Cobalt Chloride, as it becomes saturated its color changes from deep blue to pink. Since it is easy to inspect, blue indicating silica gel are commonly used for products which are relatively sensitive to humidity. However, because it contains Cobalt Chloride which has been classified as a carcinogen agent, it cannot be used in food and pharmaceutical industries.
