Molecular sieve
Truemei offers 3A molecular sieves and Normal molecular sieves. As the special desiccant for insulating glass, the 3A molecular sieve can best meet all performance indexes of it. Normal molecular sieves (Insulating glass molecular sieves) can adsorb the water and organic residues inside of insulating glass. It helps insulating glass to remain bright and transparent even at very low temperatures, and at the same time it can reduce powerful pressure of insulating glass which caused by the great changes of seasons and day-night temperature difference.
3A molecular sieve
Normal molecular sieve
They do not influence insulating glass physical and chemical properties. They can continuously absorb water and residual organic matter in an insulating glass spacer layer, effectively preventing frosting and dew of glass. They completely solve the problem of distortion and breakage caused by the expansion or contraction of insulating glass.
Processing
The qualified rate range of granules should be controlled above 98%. The larger size is suitable for
manual filling, while the smaller size is suitable for mechanical filling.
Packaging Units
Drum package
2.5kg*10bags
Carton package
5kg*5bags
Storage
The molecular sieve shall be sealed storage. It should be filled quickly when using and sealed in time
if one-time did not use up, to prevent moisture absorption.

Molecular Sieve Frequently Asked Questions
Molecular sieves are porous crystalline materials with a highly regular microscopic channel or pore structure. Molecular sieves are able to selectively adsorb or separate specific molecules based on their size and shape.
Truemei molecular sieves can be used for gas separation and purification (oxygen, nitrogen, hydrogen), drying and dehydration (natural gas, solvents, air), catalysis (petrochemical processes, fine chemicals) and adsorption (removal of pollutants, water purification) .
Compared to other desiccants such as silica gel or activated alumina, molecular sieves offer higher adsorption capacity, greater selectivity for water molecules, thermal stability, and the advantage of reuse.
There are several types of molecular sieves, such as zeolites (aluminosilicates) and synthetic molecular sieves (aluminum phosphates, silica-aluminum phosphates, etc.) Truemei mainly sells 3a molecular sieve.
In desiccant applications, molecular sieves effectively adsorb and remove water vapor from gases or liquids. Their porous structure provides selective adsorption properties, making them the drying process of choice for many industrial applications.
When selecting molecular sieves for a particular application, a variety of factors should be considered, including pore size and structure, chemical composition, adsorption capacity, thermal stability, regeneration temperature, and compatibility with the substance being treated.
