Study on hydrophilization modification of polypropyrene microporous hollow fiber membrane
Huang Zheng-qing · Membrane science and technology/Membrane science and technology series · 2000
The influences of the concentration and consist of hydrophilization solution and the optimum immersing time were discussed. The experimental results show that hydrophilization results of the pressuring method is better than that of the immersing method, and the membrane has an excellent flux after 75% ethanol solution through the membrane for 30 seconds by the pressuring method. In addition, the flux of hydrophilization membrane will rapidly drop within an hour of operation, and then become stable, and 10% HCl solution can effectively restore the flux.
