▎ 摘　　要

NOVELTY - Preparing high-performance anti-peeling modified filter comprises (1) dispersing the amphoteric polymer modifier and nanoparticles in deionized water to prepare modified solution, ultrasonically treating the nanoparticles to uniformly disperse, where the mass concentration of the amphoteric polymer modifier in the modified solution is 0.1-2 wt.%, the mass concentration of nanoparticles is 0.1-5 wt.%, (2) soaking the filter cloth into modified solution, soaking for 1-24 hours, and heating at 50-70℃ for 1-5 hours, (3) using chloroform as a solvent, preparing polyvinylidene fluoride solution with a mass concentration of 0.1-1 wt.%, soaking the filter cloth into the polyvinylidene fluoride solution, where the soaking time is 1-5 hours, and (4) irradiating the filter cloth with ultraviolet rays. USE - The high-performance anti-peeling modified filter cloth is useful for vacuum filter. ADVANTAGE - The modified filter cloth has high water flux, long operation time and high flux recovery rate after cleaning. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for high-performance anti-peeling modified filter cloth for vacuum filter.
