What is Molecular Sieve Activated Powder?

1. What Are The Raw Materials And Production Process Of Molecular Sieve Activated Powder?

The main raw material of molecular sieve activated powder is aluminosilicate. 3A is potassium sodium aluminosilicate, 4A is sodium aluminosilicate, and 5A is sodium calcium aluminosilicate. The production method of molecular sieve activated powder is to activate the original powder at high temperature to produce a powder with adsorption properties.


2. The Main Function Of Molecular Sieve Activated Powder (what is the difference with defoamer)?

Xintao Activated Molecular Sieve Powder, has the character of high dispersibility and rapid adsorbability. It is used in some special absorptive circumstances, such as being formless desiccant, being adsorbent mixed with other materials etc.

It can remove water eliminate bubbles, increase uniformity and strength when being additive or base in paint, resin, polyurethane and some adhesives.

It can also be used as desiccant in insulating glass rubber spacer.

Molecular sieve activated powder absorbs excess water in the system, and defoamer is defoaming and does not absorb water.

The principle of defoamer is to break the balance of foam stability, thereby allowing the cells to burst. Molecular sieve activated powder absorbs water and is used to break the balance of water phase and oil phase to defoaming.


3. Why The Bigger The Hole, The More ExpensiveThe Price, And Why The Price Of 4A Is The Lowest?

The price of 4A is the lowest because the 3A and 5A molecular sieve activated powder are chemically replaced by the 4Amolecular sieve activated powder.


4. What Is The Difference Between Molecular Sieve Activated Powder And Original Powder?

The difference is that the original powder is the raw material of the molecular sieve activated powder, and the original powder has no activity and cannot absorb water.


5. Which Glues Are Suitable For Molecular Sieve Activated Powder?

Any trace moisture in the glue that will affect the properties of the product, molecular sieve activated powder can be used.


6. What Is The Temperature That Molecular Sieve Activated Powder Can Withstand In Glue?

There is no problem below 500 degrees. When the original molecular sieve powder is at 550 degrees, high-temperature roasting will lose crystal water. When the temperature is lowered to room temperature, it will slowly absorb water and recover. When the roasting temperature is 900 degrees, the crystal structure is destroyed and cannot be recovered, so it does not have water absorption. Therefore, the temperature of activated powder below 500 degrees can be tolerated.


7. What Is The Recommended Dosage Of Molecular Sieve Activated Powder?

The amount of molecular sieve activated powder added is determined according to the trace moisture to be removed in the system. Static water adsorption at 24 means that under ideal conditions, the amount of water that molecular sieve activated powder can absorb is 24% of its own weight.


8. Will The Molecular Sieve Activated Powder Affect The Viscosity Of The Glue?

The molecular sieve activated powder does not have the effect of increasing the viscosity, and the effect on the viscosity of the system is only the effect of adding other inorganic materials.


9. Can Molecular Sieve Activated Powder Be Added To Polyols?

The A component of the two-component polyurethane is generally polyester polyol and polyether polyol, and the molecular sieve activated powder is generally added to the A component.


10. Will The Molecular Sieve Activated Powder Spit Water Back, Such As In The Ink?

No. Activated powder is also a kind of molecular sieve, which belongs to static molecular sieve and cannot be regenerated in the system. Molecular sieve adsorption and desorption are conditional. Desorption requires high temperature and low pressure. In customer use, molecular sieve activated powder forms a homogeneous substance with resin and does not have desorption conditions, which is also the reason why activated powder cannot be regenerated. (Resin is one of the materials of some inks).
