new material
3A molecular sieve activated powder is a highly efficient desiccant designed for precise moisture control in industrial applications. Engineered with an optimized pore structure, it selectively adsorbs water while preventing the uptake of larger molecules, ensuring superior drying performance and chemical stability. This material is widely used in coatings, adhesives, insulating glass production, and fine chemical synthesis, delivering reliable moisture adsorption for continuous processing.
Product Overview
3A molecular sieve activated powder is produced by subjecting 3A molecular sieve powder to a high-temperature calcination process. During calcination, most of the structural water is removed, enhancing the sieve’s activity and turning it into a highly active adsorbent with selective adsorption properties. This product is widely used across various industrial sectors, especially in the production of polyurethane, coatings, adhesives, and sealants, where it effectively absorbs moisture and other impurities without altering the physical or chemical properties of the final product.
Key Features
- High Activity: The calcination process imparts strong adsorption capacity to the powder, making it suitable for a wide range of adsorption applications.
- Selective Adsorption: Exhibits excellent selectivity, capable of efficiently adsorbing moisture, CO₂, H₂S, and other gaseous impurities.
- Preserved Product Integrity: While adsorbing impurities, it does not affect the physical or chemical properties of the product, ensuring process stability.
- Multifunctionality: Acts as a drying agent or catalyst support, contributing to a variety of industrial applications.
Applications
- Polyurethane Production: Used in the production of polyurethane products (e.g., coatings, adhesives, sealants), preventing foam formation and extending product lifespan.
- Insulating Glass Drying: Serves as an amorphous drying agent in insulating glass composite sealants, helping absorb moisture.
- Catalyst Support: Functions as a catalyst support in petrochemical and other chemical processes, enhancing catalytic performance.
- Selective Adsorption: Used in the production of coatings, polymers, etc., to adsorb CO₂, H₂S, and other gases, ensuring consistent product quality.
- Environmental Management: Applied in gas separation, purification, and desulfurization processes for effective adsorption and removal of impurities.
