China Molecular Sieve Desiccants Molecular Sieve 3A Suppliers

Molecular Sieve 3A Introduction:
This product can absorb the moisture in the insulating glass and residual organic matter, so that even at very low temperatures the insulating glass is still bright and transparent, and can fully reduce the hollow glass due to seasonal and day and night temperature difference between the tremendous changes in internal and external pressure, Completely solve the common hollow glass desiccant easy to make hollow glass expansion or contraction caused by the problem of twisting and crushing, and fully extend the service life of insulating glass.
The difference between 3A and 4A:
3A Molecular Sieve desiccant formula:0.67K2O.0.33Na2 O.Al2 O3.2SiO2.4.5H2O
Silicon and aluminum rate:SiO2/AI2O3≈2
Effective hole diameter:3A
4A Molecular Sieve desiccant formula:Na2 O.Al2 O3.2SiO2.4.5H2O
3A MSD Application:
Mainly used in the construction and glass industry, Petrification, Gas extracting and purify.

ItemWater3A MSDOxygenNitrogen4ASemi-Diameter,
A, 10 -10 m2.7633.463.644So the water semi-diameter smaller than the 3A MSD, can be absorbed by the 3A MSD, but the Oxygen and Nitrogen semi-diameter larger than 3A MSD, cannot be absorbed by the 3A MSD. In a similar way, 4A MSD can absorb the water, Oxygen and the Nitrogen.
If use 4A MSD in the insulating glass, the inner pressure less than outside pressure as inner Oxygen and Nitrogen be absorbed by the 4A MSD, so make the insulating glass transformation and easy to damage.
3A MSD Application in the insulating glass:During the canning of MSD, should be process in the dry room, operation temperature is 15-20ºC.When open the package, the MSD is forbidden expose in the air long time, the time from canning to sealing should be control in 45 minutes and continuously.There should no leakage around the insulating glass when used in MSD.It is forbidden to exposure in the sun after sealed for the insulating glass.When the package for MSD damaged, the MSD need to do test, after test qualified, then can be used.Parameters:
Standard: GB/T 10504-2008
