3A Molecular Sieve Powder

3A molecularsieve powder is obtained from NaA molecularsieve powder that has been exchanged with K+. K+ is the hydrate or crystalline silica aluminate metallic salt. 3A molecular sieve dust has characteristics such as uniform particle size, stability and quality.

About 3A Molecular Sieve Powder:

Chemical properties:

3A molecular sieve powder is a silicoaluminate; its chemical formula is NaA12O20·12H2O. It is a white or light green solid powder with high chemical stability. Under normal conditions, 3A molecular sieve powder does not easily react with acids, alkali, salt and other substances, so it has good corrosion resistance.

Physical properties:

3A molecular sieve powder has a high specific surface area and pore volume, which gives it good adsorption performance. In addition, it also has a lower density, better mobility, and is easy to transport and use. 

Adsorption properties:

3A molecular sieve powder has excellent adsorption properties and can absorb water, carbon dioxide, nitrogen and other small molecules. Its adsorption capacity depends mainly on its pore size and specific surface area. Due to its moderate pore size, it can adsorb both larger and smaller molecules. In addition, 3A molecular sieve powder also has good selective adsorption properties, which can be used to separate and purify components in gas and liquid mixtures.

Production Method of 3A Molecular Sieve Powder:

Raw material preparation:

Preparing the required raw materials is the first step in producing 3A molecular sieve powder. These raw materials mainly include sodium silicate, aluminum hydroxide and so on. The quality directly affects the final product's performance in the preparation process.

Mixing and reaction:

The prepared raw materials are mixed in a particular proportion, and the appropriate amount of water is added for the reaction. This reaction is carried out under high temperature and pressure conditions to promote the formation of molecular sieve crystals. During the reaction process, key parameters such as temperature.

Seed preparation:

In the reaction process, it is necessary to add seed as a seed to promote the formation of molecular sieve crystals. The preparation of crystal seeds is a crucial step, which needs to control parameters such as temperature and pH value to ensure the purity and quality of crystal seeds.

Crystallization and drying:

After adding the seed, the reaction continues to promote the formation of molecular sieve crystals. In this process, it is necessary to control the temperature, pH value and other parameters to obtain high-purity molecular sieve crystals. The resulting crystals are then dried to remove water and other impurities.

Grinding and screening:

The dried crystals must be crushed and sieved to obtain 3A molecular sieve powder with different particle sizes. In this process, it is necessary to control the conditions of crushing and screening to ensure that the particle size and quality of the final product meet the requirements.



Applications of 3A Molecular Sieve Powder:

Desiccant:

3A molecular sieve powder has excellent adsorption properties and can adsorb small molecules such as water and carbon dioxide. Therefore, it is widely used in the field of desiccant. In industrial production, many substances, such as electronic components, medicines, food, etc., must be dried before they can be used. 3A molecular sieve powder, as a desiccant, can effectively remove moisture in the air and keep the environment dry. At the same time, it has good selective adsorption properties and can separate and purify components in gas and liquid mixtures.

Catalyst:

3A molecular sieve powder has excellent catalytic properties and can be used as a catalyst in petrochemical and natural gas chemical reactions. In the petrochemical industry, many reactions must be carried out under high temperatures and high-pressure conditions, and 3A molecular sieve powder can be used as a catalyst, effectively improving the reaction rate and selectivity and reducing the occurrence of side reactions. At the same time, it has good corrosion resistance and stability and can adapt to various reaction conditions.

Adsorbent:

3A molecular sieve powders have excellent adsorption properties and can separate and purify components in gaseous and liquid mixtures. In industrial production, many substances need to be separated and purified to be used, such as gas separation, mixture separation, sewage treatment and so on. 3A molecular sieve powder, as an adsorbent, can effectively adsorb the components in the mixture, separate them, and purify them. At the same time, it also has good selective adsorption performance and can selectively adsorb target components.

Carrier:

3A molecular sieve powder has a large specific surface area and pore volume and can be used as a carrier for preparing catalysts or carrier catalysts. In catalyst preparation, the carrier can provide the active center and support structure to promote the activity of the catalyst. As a carrier, 3A molecular sieve powder can effectively improve the activity and stability of the catalyst. At the same time, it has good corrosion resistance and stability and can adapt to various reaction conditions.
