Silica gel Dubai
Silica gel is very familiar to all. It is a common substance not only in-between industrial people but also in common people. It is a desiccant. It can absorb moisture around 60 to 65 percentage of its maximum weight. Therefore it can be used to protect items which are being damaged due to moisture.
Contrary to its name, silica gel is really a dry solid that absorbs and holds water vapor. Silica Gel is normally found in the form of pearls or beads. These beads contains a porous structure material that allows the beads to freely absorb moisture from the surroundings.
Benefits of Silica Hydrogel: Synthetic amorphous silica hydrogel is ideally fitted to use as an adsorbent in refining edible oils, offering variety of environmental and price benefits. To attract polar impurities from the oil, the high water content trapped by the desiccant structure creates the ideal environment.
Contaminants like soaps, phospholipids and trace metals are drawn into the pores of the silica gel and adsorbed onto the silica surface which is populated with a high concentration of hydroxyl groups. The pore structure of the silica granules offers a high internal area to soak up the polar contaminants.
Each tiny particle of desiccants, typically 15 microns in size, is like a small sponge with a high adsorption capacity. For comparison, lets check typical properties of a bleaching clay-based natural silicate adsorbent and silica hydrogel.
Silica Hydrogel has a surface are m2/g 615 but clay based natural silicate has just 150. Pore volume also higher in silica gel as 1.31 mL/g and for clay based natural silicate it is 0.51 only. Average particle size of silica gel is in microns 17.5 and for silicate it is 21.1. Permeability is 0.11 for silica gel and 0.03 for clay based natural silicate.
