How Does Silica Gel Work?
Silica Gel as a Desiccant The primary use of silica gel is as a desiccant, which means that it absorbs moisture. Silica gel has a high surface area that allows it to soak up liquids, gases and vapors that surround it. This property has led to its use in the food preservation industry as little packets that are placed inside the packaging of a large variety of foods. Since moisture can cause mold and other damage, silica effectively helps preserve the food. Silica gel packets are also used in leather goods, footwear, and just about any other product that needs to be protected from moisture. Silica also works as a desiccate within the industrial compressed air industry. Silica beads are used as a filtration system to control moisture and remove any condensation that may damage the air flow systems. Silica gel is also sometimes used by museums, libraries and high-end art galleries to control moisture and humidity in the air, in order to minimize damage to valuable works. Silica in Chemist
