We all know that molecules are very small particles that make up substances, which cannot be seen by the naked eye. Various substances have molecules of different sizes and shapes. It is very difficult to distinguish them. However, molecular sieves Desiccant can do this job.

The structure of the molecular sieve desiccant is like a sponge, with densely packed pores arranged inside, and the pores are interconnected and criss-crossed. According to calculations, the inner surface area of the pores per gram of molecular sieve can reach more than 800 square meters. When various substances pass through the molecular sieve, only a small amount of small molecules can pass through. Break free, so as to achieve the purpose of screening molecules. This is also the origin of the name "molecular sieve".

Commonly used desiccants include calcium chloride desiccant, silica gel desiccant, etc., which can reduce the water content in the air to about 0.4g/m3, and the use of molecular sieve desiccants can reduce the water content in the air to 0.01g /m3 or less. It can be seen that molecular sieves can make the ambient air drier. In addition, the water absorption of the molecular sieve desiccant is very little affected by the relative humidity, even when the relative humidity is 10%, there is a high adsorption capacity.
