Productdetails    Size：3.5x4.6 in  Net Weight：20g/pack  Number of Items：300 Hygroscopic material: 13X Molecular Sieve Powder  Applies to：3D Printer Filament Storage, 3D Printer Filament Dryer   [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
