HIGH-STRENGTH HOLLOW FIBER MOLECULAR SIEVE MEMBRANE AND PREPARATION METHOD THEREFOR

摘要

A high-strength hollow fiber molecular sieve membrane and a preparation method therefor. A carrier of the high-strength molecular sieve membrane has a multi-channel hollow fiber configuration. The preparation method comprises first preparing a crystal seed solution, then immersing the dry carrier with the multi-channel hollow fiber configuration in the crystal seed solution, and extracting and drying the carrier to obtain a crystal-seeded carrier; and finally placing the crystal-seeded carrier in a molecular sieve membrane synthetic fluid, performing hydrothermal synthesis, and taking out, washing and drying the product to obtain the high-strength hollow fiber molecular sieve membrane.
