摘要 本工作将Cu-Zn合金粉末与α-Al2O3粉末共混,采用相转化烧结技术制备了Cu-Zn/α-Al2O3中空纤维膜,其烧结温度为1300℃。运用电子扫描显微镜(SEM)对中空纤维膜的横截面以及外表面进行了分析,并研究了Cu-Zn合金添加量对膜性能的影响以及膜的抗菌性能。结果表明,制备的Cu-Zn/α-Al2O3中空纤维膜的平均孔径范围为0.314~0.438μm,最佳Cu-Zn合金添加量为3%(质量分数,下同),此时纯水通量为2462.11L/(m2·h),抗弯强度为8.11MPa,过滤除菌率为99.99%,抗菌率为73.1%。

Abstract: In this work, Cu-Zn alloy powder and α-Al2O3 powder were blended to prepare Cu-Zn/α-Al2O3 hollow fiber membrane using phase transformation sintering technique. Sintering temperature was 1 300 ℃. Cross-section and outer surface of the hollow fiber membrane were studied using electron scanning microscope (SEM). The effect of Cu-Zn alloy content on membrane properties and Cu-Zn/α-Al2O3 hollow fiber membrane's anti-bacteria properties were studied. Results show that average pore size range of Cu-Zn/α-Al2O3 hollow fiber membrane is 0.314—0.438 μm. The optimal Cu-Zn alloy content is 3% (mass fraction), at which content pure water flux is 2 462.11 L/ (m2·h), bending strength is 8.11 MPa, bacteria reduction rate is 99.99%, bacteria inhibition rate is 73.1%.
