Molecular Sieve
3A for Insulating Glass
1. Molecular sieve profile
Molecular sieve (also called as synthesized zeolite) is a kind of silica-aluminates with micro-porous crystal. It is a frame-work which is constructed by SiO2 and Al2O3. Molecular sieve has very similar aperture value (only several A) and large surface area.
There are relevant positive ions in its lattice to balance the negative ions in the crystal frame. Different molecular sieves have different
shapes and different aperture values. We could separate different kinds of molecular by selectively using different molecular sieves.
Water is a sort of polar molecule, molecular sieve type A has dramatic affinity for water. For the above reasons, molecular sieve is
considered as the most ideal desiccant. The molecular sieve here mentioned is type 3A which is only for adsorbing water.
The water adoption depth of molecular sieve 3A is above several dozen times higher than other any other applicable desiccants.
2. Molecular sieve 3A
Most molecular sieves have been affinity to water, such as other molecular sieve 4A, 5A, *3X, type Y and so on.
They all also adsorb other molecules from air. The pore of molecular sieve 3A is 3 angstrom, which can only adsorbs molecule
smaller than this size, water molecule is just meet this size, so molecular sieve 3A can only adsorb water other than Nitrogen
and Oxygen in air.The following form lists 4 types of common desiccants often used in IG and their aperture values.
3. Molecular sieve 3A and insulating glass desiccant
If use other molecular sieve as desiccant, these molecular sieves can also adsorb nitrogen or oxygen in air at lower temperature,
and could release air at higher temperature, the inflated and shrinking air could cause window to be distorted with the temperature
changing at day-night or seasons changing. Up to now, molecular sieve 3A is the unique proper desiccant which is suitable
for insulating glass unit.
4.
JSBA 3A molecular sieve sieve
3A insulating glass (IG) desiccant (JSBA sieve) is made from molecular sieve 3A. This IG desiccant can deeply co-adsorb resident moisture and organics in insulating glass, keep the IG clear and transparent even at very low outside temperature,
prevent the condense of inside vapor. More importantly, it can resolve the problem of window distortion caused by IG inflation
and shrinking under season or day-night temperature changing; this would prolong the life span of IG windows considerably.
