Insulating glass molecular sieve is one type of zeolite molecular sieve. Its main material is zeolite. There are normally include 3A insulating glass molecular sieve and 4A insulating molecular sieve.
Insulating glass molecular sieve is used in insulation glass. It can absorb water and residual organic matter in the insulating glass and keep it clean even in very low temperature. The special type of molecular sieve can fully reduce the strong internal and external pressure difference of the insulation glass due to the great change temperature difference caused by season change and day light change. It can fully prolong the service of the insulating glass.
The application of insulating glass molecular sieve
1).Absorbing the water in insulating glass molecular sieve to get drying effect.
2).Anticoagulant function
3).Cleaning
It can adsorb the floating dust in the air and it has very low own powder dropping.
4)Environmental effect
It is not harmful to the environment and can be used recycling
5)Energy conservation
It is completely sealed in the insulating glass to ensure the energy conservation of the insulating glass
We normally have two types of insulation glass molecular sieve including normal 4A insulating glass and 3A insulating molecular sieve.
Following is the detailed information for these two types.
4A insulating glass molecular sieve
It is an economic choice for insulating glass. The 4A insulating glass molecular sieve is much cheaper than 3A molecular sieve. But it can not be used in very low or very high temperature. So it could only be used in warm area. The available size could be dia0.5-0.9mm, dia1.0-1.5mm, dia1.6-2.5mm, or other customized size.

3A insulating molecular sieve
3A insulating glass molecular sieve is the professional insulating glass molecular sieve. It can bear temperature from -50℃ to 50℃. It can keep the insulating glass very clean even under very low temperature.It has high efficiency besides high cost. In order to keep high quality of the insulating glass at any conditions, many manufacturers always keep choosing 3A insulating molecular sieve.

How many molecular sieve we need for insulating glass
Molecular sieve is very important for insulating glass. It is used to prevent dew and frost in the insulating glass. It can also prevent the solvent from volatilizing in the insulating glass.
How many molecular sieve absorbent are needed for insulating glass? We can answer this question in three ways. They are experience, water balance and equivalent weight. For experience, most of the manufacturer will feed molecular sieve absorbent in two sides of the insulating glass. It could be two long sides or one long side and one short side. Water balance is a scientific method to provide enough absorbent to remove the water permeated during the manufacture.If use this method, we need know the design life of the insulating glass and the maximum dew point required for the life of insulating glass. The equivalent weight required is the minimum absorbent weight per inch required for testing insulating glass.
