Molecular sieve manufacturer: What role does molecular sieve play in insulating glass?

Molecular sieve is an ideal adsorbent for insulating glass. Molecular sieve is a porous structure with very large internal and external surface areas. In short, it has an affinity for water and solvents. The following molecular sieve manufacturer talks about the role of molecular sieves in insulating glass.

Molecular sieves play an important role in insulating glass to avoid condensation and frosting on the inner surface of insulating glass, evaporation of solvents in sealants, deflection under severe weather conditions, and hydrocarbons in the air such as paints, detergents and other solvents . Because in the process of production and use, the water vapor in the air will be sealed in the insulating glass. When the ambient temperature drops below the dew point of the gas in the insulating glass, condensation will occur, and condensed water will form on the inside of the cold surface of the insulating glass.

How much adsorbent should be used for insulating glass? It can be answered from three aspects: experience, water balance or demand equivalent. Experience has shown that most manufacturers choose two long sides or one long side and one short side to pack the sorbent, and in many cases this has been satisfied. Water balance is a scientific method, there must be a satisfactory sorbent to remove the moisture entering in the production process and the service life of the insulating glass, only a small part of the sorbent is used to start the drying process. The "relative humidity driving force" will cause moisture to enter the interior of the insulating glass. When the external humidity is higher than the internal humidity of the insulating glass, this driving force will be generated. The water removal amount during the service life of the insulating glass can be calculated by the water balance. This calculation requires Know the water feed rate, the planned life of the insulating glass and the required maximum dew point during the life of the insulating glass. Demand equivalent refers to the minimum amount of drying required per inch when testing insulating glass.
