White Silica Gel Desiccant (Granular or Beaded)
White Silica Gel Desiccant, Granular or Beaded: Is an activated adsorbent that comes in many mesh sizes for use in different industrial applications. Silica gel does not corrode other substances, has no smell or taste, and is nontoxic and chemically non-reactive. Its internal surface area is very large, making it able to adsorb a great deal of moisture. The process of adsorption does not create any byproducts, nor do any chemical reactions take place. It doesn't change in shape or size, either, because it is non-deliquescent. It will still be free-flowing and dry even when it has adsorbed all the water it can.
White silica gel prefers to adsorb water over almost any other substance. However, it can also be used to adsorb C12, CO2, gasoline-range hydrocarbons, HC1, sulfur and nitrogen compounds, and other substances. White silica gel, granular or beaded, is used in industry in many situations where there is a need for selective absorbency or a desiccant with a high capacity for moisture.
Silica gel can adsorb HC1, C12, CO2, water, and aromatics in substantial quantities. It is a nontoxic, non-corrosive moisture control solution, given that it keeps its shape and size no matter what happens to it, and does not react in the presence of other chemicals. For these reasons, packets of white silica gel, granular or beaded, can prevent spoilage and damage to goods by inhibiting the growth of mold.
These packets are used extensively to absorb moisture in packaged products ranging from medicine to electronics. Silica gel packets are also used to desiccate (dry out) the air circulating through compressed air systems. When the compressed air passes through a packet of white silica gel, moisture is kept out of the system, preventing it from breaking down. Silica gel can be used in railway locomotives in the same way as in industrial settings. At the same time, satellite and radio transmitters that operate at high frequencies often depend on a moisture absorber and a compressed air system to keep the signal from degrading.
Another common use for white silica gel desiccant is as a preservation agent in the collections of museums and libraries. Silica gel packets preserve the integrity of the items these institutions store by removing moisture from the air. Some of these items are very old and must be kept in humidity-controlled environments to prevent damage. Among the many other uses for silica gel are long-term storage, and as a component in cat litter.
