Product Description

 

High Quality Molecular Sieve 3A Pellet as Adsorbent

Product Introduction
The lattice pores of type 3A molecular sieve is only 3 angstroms, which is the smallest of all molecular sieves. It can only absorb water and cannot absorb any other components in the air, because the critical diameter of water molecules is 2.8 angstroms and the polarity is very strong. Any other type of molecular sieve will adsorb oxygen or nitrogen in the air, and this adsorption capacity is very sensitive due to small changes in temperature.

As a special desiccant for insulating glass, 3A molecular sieve can best meet all the performance indexes of insulating glass without any influence on its physical and chemical properties. It can continuously and deeply adsorb the water and residual organic matter in the insulating glass spacer layer, effectively prevent the condensation and frost of the glass, completely solve the problem of distortion and breakage caused by the expansion or contraction of the insulating glass, and ensure that the insulating glass is as short as 20 years -8ºC Dew point life. Therefore, only 3A molecular sieve can be used as an insulating glass desiccant.

Precautions
1. The insulating glass desiccant should be sealed and stored before use. When in use, it should be filled quickly, and the unused molecular sieve should be sealed in time to avoid moisture absorption.
2. Molecular sieve that cannot be determined whether it absorbs moisture should be tested for temperature rise. When the temperature rise is lower than 33 degrees Celsius (25 grams molecular sieve/25 ml water), it cannot be used again and should be recycled by the manufacturer.
3. The manufacturer should have at least two detection methods for temperature rise and molecular sieve desiccant outgassing.

1. Molecular Sieve
Molecular sieve (also known as synthetic zeolite) is a kind of aluminosilicate microporous mesh crystal, composed of SiO2 and Al2O3 tetrahedra, with uniform pore size (about a few angstroms) and extremely large surface area. There are metal cations (such as Na+, K+, Ca2+, etc.) in the molecular sieve lattice to balance the excess negative charges in the tetrahedron. Different types of molecular sieves have different pore sizes or shapes, and can be used to separate a variety of different molecules. Water is a very polar molecule. Type A molecular sieve has a very high affinity with water, and is often used as a desiccant with excellent effects. The molecular sieve we are talking about here refers to a 3A (1A=10-10m) molecular sieve that can only be used to absorb water molecules. It is dozens of times higher in drying capacity and depth than silica gel desiccant, alumina desiccant and any other types of clay desiccants.
 

3A molecular sieve and insulating glass desiccant
In view of the description in 2, when the temperature is slightly reduced, other types of molecular sieves will adsorb a large amount of air in the hollow glass, resulting in a vacuum state; when the temperature rises, the molecular sieve will release a large amount of air into the spacer layer, resulting in hollow The air in the glass expands. With the change of temperature difference between day and night and the changing of seasons, insulating glass is easily distorted and broken due to expansion and contraction, shortening its life span, and sudden breaking of glass will cause major safety accidents. Therefore, it is strictly forbidden to use non-3A molecular sieve as the hollow glass with dry air. Desiccant.
4. Green Energy 3A Molecular Sieve (Insulating Glass Desiccant)
As a special desiccant for insulating glass, 3A molecular sieve can best meet all the performance indexes of insulating glass without any influence on its physical and chemical properties. It can continuously and deeply adsorb the water and residual organic matter in the insulating glass spacer layer, effectively prevent the condensation and frost of the glass, completely solve the problem of distortion and breakage caused by the expansion or contraction of the insulating glass, and ensure that the insulating glass is as short as 20 years -8ºC Dew point life. Therefore, only 3A molecular sieve can be used as an insulating glass desiccant.
