Correct use of molecular sieve-Ⅰ

1. Definition of molecular sieve

Silicate molecular sieve is a kind of microporous crystal material with skeleton structure and cage structure. Water molecules will be absorbed into the molecular sieve under the action of adsorption force to achieve the purpose of drying.

2. Reasons for selecting molecular sieve as insulating glass desiccant

The role of the desiccant in the insulating glass is to absorb the moisture in the insulating glass interlayer to reduce the dew point and prevent the glass from fogging. Molecular sieve was selected as the desiccant for insulating glass, mainly because of its strong adsorption performance and stable chemical properties under high temperature and low humidity conditions.

Molecular sieve can have good water absorption performance at low water content and high temperature. This is an important reason for selecting molecular sieve as the desiccant for insulating glass.

The lower the water content of molecular sieve, the lower the corresponding dew point. When filling the desiccant, the faster it is, the better it is to maintain the moisture content of the molecular sieve and reduce the dew point of the insulating glass.

The chemical property of molecular sieve is stable, non-toxic and tasteless. Under normal conditions, it will not react with aluminum strip and glass to ensure the service life of insulating glass. This is another reason why molecular sieve is selected as the desiccant for insulating glass.
