Non Toxic and Highly Absorbents Molecular Sieves

Molecular sieves are said to be those type of desiccants which although has almost same appearance with that of silica gel but has different completely different properties as compared to silica gel. This desiccant is produced synthetically with the help of metal amino silicates. Molecular sieves are absolutely safe to use with the food items as it is absolutely nontoxic but at the same time are highly porous. It appears to have a pinkish color, tiny opaque beads which have several internal cavities, connected with each other with the help of internal window openings.

The other type of desiccant is dehydrated ethanol. Ethanol dehydration means a process where the water molecules or something equivalent to water molecules are removed from the substance. Ethane and water is produced by dehydrating ethanol by heating it over certain temperature with sulfuric acid. The vapors of ethanol can be easily dehydrated by passing any type of heated catalyst, which will produce ethane gas. This process is also called as ethanol drying.

Molecular Sieves 3A for All Humidity Problems

All the windows are of similar diameter. Diameter plays an important role in the working of molecular sieves. Its accurate diameter is the unique identification which differentiates it from the other desiccants. Different types of Molecularsieves are 3A, 4A, 5A, 10A which is also known as 13X. So, if the molecules of the elements have smaller diameter as compared to the window opening of the desiccant, the process of absorption happens otherwise it will not.

As it has high network of pores, Molecular sieves can be said as the ultimate source for absorbing moisture. This feature makes it demanding in the industrial sector. This absorbent is synthetically produced from Zeolite and has innumerable internal cavities which absorbs moisture and locks it inside them. These desiccants can either be used individually or you also have the option to use it in combination with other desiccant, in this way you can get optimal solution. Different types of desiccants have different type of absorbing qualities. In the case of molecular sieves, it has the capacity to absorb moisture or gas up to 20 times of its own weight. Since, it is one of the most effective and aggressive absorbents available in market, it costs a little higher than the other desiccants. This desiccant is used in various organizations like pharmaceutical and medical industry, food and refrigeration industry and also cosmetics and petroleum industry. Apart from this, it is widely used in electronic and computer industry.
