• [Structure and Composition]: 13X molecular sieve powder is a crystalline aluminosilicate with a uniform pore structure. It is composed primarily of silicon dioxide (SiO₂) and aluminum oxide (Al₂O₃), creating a robust and stable framework with a pore size of about 10 angstroms (1 nm). It is a type of synthetic zeolite, is renowned for its excellent hygroscopic properties.
• [Adsorption Mechanism]: The drying function of the 13X molecular sieve operates through both physical and chemical adsorption processes:
• [Physical Adsorption]: The extensive surface area provided by the internal pore structure of the molecular sieve allows for significant physical adsorption of water molecules. This is driven primarily by Van der Waals forces, which attract and hold the water molecules onto the surface of the pores.
• [Chemical Adsorption]: The surface of the 13X molecular sieve contains active sites that can interact with polar molecules like water. These sites can form weak chemical bonds or coordinate with water molecules, enhancing the adsorption capacity. The highly polar nature of water makes it particularly susceptible to being adsorbed by these active sites.
• [Excellent moisture absorption ability]: It can control the humidity keeping to 0RH. It is mostly used in high-end manufacturing industries, such as petrochemical industry, natural gas processing and air separation. Therefore, it is widely used in the drying of handicraft industry, so that improve process efficiency and product quality. Such as 3D Printer Filament Bundle, wood craft material storage and other versatile drying agent in various applications.
