We all know that molecules are very small particles that make up matter, which cannot be seen by the human eye at all. Although the shape and size of various substances are different, it is extremely difficult to distinguish them from each other. However, molecular sieve desiccant can do the job.

The structure of molecular sieve desiccant is like a sponge, with dense holes arranged inside, and the holes are interconnected and criss-crossed. After calculation, the inner surface area of ​​each gram of molecular sieve holes can reach more than 800 square meters. When different substances pass through the molecular sieve, only some small molecules can flow unimpeded. , unable to break free, so as to achieve the purpose of screening molecules. This is also the origin of the name "molecular sieve".

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