3A molecular sieve is indeed produced in strip form, catering to specific industrial packing needs. These 条状 (strip-shaped) variants are typically cylindrical, with diameters ranging from 3–6 mm and lengths of 5–10 mm, engineered to balance surface area and flow dynamics in drying or purification systems.
Strip-form 3A molecular sieve offers advantages in packed columns: its elongated shape ensures uniform void distribution, reducing pressure drop compared to irregularly shaped particles. This makes it ideal for high-flow applications like compressed air drying, where consistent gas passage is critical. The strips’ structural rigidity also minimizes attrition during handling and regeneration, extending service life in continuous processes.
Manufactured via extrusion, strip 3A sieve retains the same 3-angstrom pore structure and potassium cation content as bead or pellet forms, ensuring identical adsorption performance—selective removal of water and small polar molecules. Its form is particularly suited for vertical column packing, where alignment of strips enhances contact between the sieve and process streams, improving moisture removal efficiency.
Suppliers often provide strip 3A molecular sieve alongside other forms, allowing customization based on system design. Whether in strips, beads, or pellets, the sieve’s core properties—pore size, hydrophilicity, and regenerability—remain consistent, ensuring reliable performance across all physical configurations.
