What are the silicales dried?
Silicagel drying is materials that adsorb water, and are usually used when the company wants to prevent damage to goods by excessive moisture. Silicagel dioxide is a basic component of silicagel drying, but some types may also contain chemicals that change the color of adsorption of moisture. Oxide is usually contained in bags, but for some purposes it is used in free form.
After the First World War, a scientist named Walter A. Patrick patented silicagel. During the war it used it inside the gas masks to capture dangerous gases. Like this application, silica dioxide, which is the technical name for silica gel, had a natural tendency to suck moisture from the environment. This feature is useful for people who want to store goods in a dry atmosphere and for people who want to dry out other objects.
Despite the name, silicagel spilling is usually in granulated or beads, not on gels. These granules can be free or may be closedin Packets of Breathable Material. The size of the packets varies depending on the air volume, which is supposed to maintain silica in dry and the manufacturer often closes the item in a plastic bag to prevent external moisture. Silicon can ads more water, about 40 percent of the original dry weight of drying than another form of drying used by clay.
Some silicagel drying include an indicator, a chemical that displays color change when certain conditions are met. In the case of silica gel, the color of the product changes when gel granules contain as much moisture as possible. Some chemicals of the indicator are orange when silica is dry and turns green with moisture. Others turn from orange to white. There is also a blue silica dioxide that changes the pink color to pink.
The advantage of silicagel spilling is that they can in their free form GRAzero Bznova usable. Drying processes such as heat or microwave energy can release moisture from silica. Once silicon is dry, the user can use it in the same way as before. Desiccants with the indicator will also turn back to the original color.
Most silica gels are not harmful to humans if they enjoy themselves. However, the blue variety uses cobalt chloride, a toxic chemical as an indicator. Any product that can be damaged by moisture, from boots to electric goods, can contain silicagel in the packaging. Drying processes, such as the preservation of seeds, may also include silicagel drying.
