subject: Know What Makes Silica Gel A Versatile Desiccant [print this page] The presence of humidity can be detrimental to several products and process, as it harbors the growth of microorganisms. This problem can be easily tackled with the help of silica gel, one of the most widely used desiccants across the world. This particular substance resembles largish grains of white sand.
Right from large scale cargo in ships to exhibition cases in museums, the use of different types of desiccants is inevitable. This particular desiccant has very high moisture absorbing capacities, making it best suited for environments where tight moisture control is called for. Another important factor that works in its favor is its inert statethis means that silica gel doesnt react with any other chemicals. Because of these very properties, it can be easily used at even in chemical factories and other places. Also, this material is non-toxic, so even if it placed in freezers or refrigerators, it will not pose a health hazard to consumers.
Did you know that research has proven that this desiccant boasts a very intricate internal network of pores that give it an internal surface area of up to 800 meters per gram? This proves the high absorption powers contained in this particular substance. In fact, it was only during World War 1 that the true importance of this desiccant came to the fore. It was used in gas masks for absorbing harmful chemicals and gases. And, it was also used to protect supplies of medicines and other objects in military camps for several days.
While all these factors make this particular desiccant very popular, there is one major aspect that truly makes it a worthwhile investment. This desiccant can be reconditioned and re-used. This means that by heating this material, and eliminating the moisture present inside, it can be re-used. This gives it an infinite life as it can be used and re-used several times over. Usually, this desiccant can be reconditioned by heating it up to 300 degrees centigrade. It might also help to know that the melting point of this material is around 1600 degree centigrade, which is relatively high.
There are several reputable manufacturers that offer this desiccant meant for a variety of uses. But to determine the exact quantity and type of silica beads that you would need to use, it is best to discuss with your chosen silica gel manufacturer.
These desiccants are a result of first-rate chemical engineering, which is why you should only depend on a reputable manufacturer. It is also important to mention here that though silica gel is referred to as a gel, it is actually in the form of hard beads. Essentially, it is an amorphous form of synthetically made silicon dioxide that is very versatile when used as a desiccant.
