What is 4A Molecular Sieve?

4A molecular sieve is a common type of molecular sieve, which is a crystalline aluminosilicate material with a pore size of approximately 4 Angstroms (Å), hence the name 4A molecular sieve. The “A” here represents Class A pore size, indicating that it is mainly suitable for adsorbing substances with smaller molecular diameters such as water, methanol, ethanol, acetylene, carbon dioxide, nitrogen, and hydrogen, while rejecting larger molecules larger than its pore size.

The main components of 4A molecular sieve include silicon-oxygen tetrahedron (SiO4) and aluminum-oxygen tetrahedron (AlO4), which are connected together by sharing oxygen atoms to form a framework with a regular pore structure. This structure gives the molecular sieve highly selective adsorption properties, allowing it to effectively separate target molecules from mixed gases or liquids.

4A Molecular Sieve Uses

Gas drying: In industrial gas treatment, 4A molecular sieve is used to deeply dry air, natural gas, argon and other gases, effectively removing moisture and certain harmful impurities (such as CO2, H2S), ensuring gas quality and improving the safety of subsequent processing. sex and efficiency.

Liquid dehydration: In the chemical and petrochemical industries, 4A molecular sieve is used for dehydration of ethanol, methanol, solvents and other liquids to ensure that these liquids meet the required low moisture content standards and prevent product deterioration or reaction failure caused by moisture.

Air purification and preparation: In oxygen production, nitrogen production and air purification systems, 4A molecular sieve can effectively absorb moisture, carbon dioxide, etc. in the air, creating necessary conditions for obtaining high-purity oxygen, nitrogen or other gases. It is also used in electronics Maintain air purity in industries and laboratories.

Drug and food drying: As a non-toxic and stable desiccant, 4A molecular sieve is used in static drying of pharmaceutical packaging, food preservation and electronic components. By adsorbing trace amounts of moisture in a closed environment, it extends the shelf life of products and prevents corrosion and deterioration.

Catalyst support and purification: In catalytic reactions, 4A molecular sieve can be used as a carrier for the catalyst, or it can be purified before the catalyst is recycled to remove accumulated impurities, restore catalyst activity, and improve catalytic efficiency.

Purification of fine chemicals: In the synthesis and purification process of fine chemicals, 4A molecular sieve is used to adsorb and remove unwanted small molecule impurities, such as in the production of spices, dyes, pesticides, etc., to ensure the purity and performance of the final product.

Environmental protection applications: In sewage treatment and exhaust gas purification, 4A molecular sieve can adsorb certain harmful substances, such as heavy metal ions, organic pollutants, etc., which is helpful for environmental protection and resource recovery.

4A Molecular Sieve Outstanding Applications in Cosmetics

Balance of oil control and moisture absorption: 4A molecular sieve has strong moisture absorption ability and can theoretically be used as an ingredient in cosmetics to absorb oil and regulate skin moisture. A care product for oily or combination skin, it can absorb excess sebum, help keep the skin dry and reduce shine, while regulating the skin’s moisture balance to prevent dryness.

Improve formula stability: In cosmetic formulas that need to maintain a low-moisture environment to maintain ingredient stability, such as some products containing easily hydrolyzable active ingredients, 4A molecular sieve can be used as an auxiliary agent to absorb excess moisture and prevent chemical reactions caused by moisture. Thereby extending the shelf life of the product.

Enhance the performance of powder products: In powdered cosmetics such as foundation and loose powder, the microporous structure of 4A molecular sieve can serve as a tiny “water reservoir”, slowly releasing absorbed moisture or active ingredients when in contact with the skin, providing longer-lasting moisturizing effect or improve skin feel.

Purification and deodorization: Due to its adsorption properties, 4A molecular sieve may be explored to remove bad smell molecules or impurities in cosmetics and improve the sensory quality of the product, especially for products containing natural ingredients, which may change over time.

4A Molecular Sieve Features

Pore size characteristics: The name of 4A molecular sieve comes from its pore size of about 4 Angstroms (Å), which allows it to effectively adsorb water molecules (diameter of about 2.8 Å) and other small molecules (such as methanol, ethanol, hydrogen sulfide, sulfur dioxide, etc.) without adsorbing molecules larger than this pore size, such as propane.

Selective adsorption: Due to its precise pore size control, 4A molecular sieve exhibits a high degree of selective adsorption capacity, which means that it can preferentially adsorb molecules of specific sizes and separate or purify specific components in the mixture.

Thermal stability: 4A molecular sieve has good thermal stability and can maintain its structure and adsorption properties at higher temperatures, which makes it suitable for use in industrial applications that require high temperature processing.

Regenerability: The used 4A molecular sieve can be regenerated through simple methods such as heating to release adsorbed substances and restore its adsorption capacity, thereby achieving multiple reuses and being economical and efficient.

Chemical inertness: As an aluminosilicate material, 4A molecular sieve is stable under most chemical conditions and does not easily react with other chemicals, which ensures its safety and applicability in various applications.

Hydration state: The chemical formula of 4A molecular sieve is Na12Al12Si12O48·27H2O, which indicates that it contains a large amount of crystal water in its initial state. These water molecules usually need to be removed by heating before use to activate the adsorption properties of the molecular sieve.

Form and particle size: 4A molecular sieve can be prepared into different forms (such as beads, strips, powder) and particle sizes as needed to adapt to different application needs. Submicron 4A zeolite has better adsorption performance and covalent carrier characteristics.
