中文摘要:
      采用相转化和烧结相结合的方法制备了氧化钇稳定氧化锆(YSZ)中空纤维陶瓷膜,研究了铸膜液中YSZ粉末含量和烧结温度对中空纤维陶瓷膜的微观结构和性能的影响。结果表明,YSZ中空纤维陶瓷膜的不对称结构包含指状结构和海绵状结构,YSZ含量会影响两种结构的比例,烧结则会引起微观结构的致密化。在铸膜液配比为m(YSZ):m(PSF):m(NMP)=5.0:1:4,烧结温度为1200 ℃的条件下制备出性能良好的中空纤维陶瓷膜,其纯水通量为2.33 m3/(m2·h·MPa),抗弯强度为134.5 MPa。
英文摘要:
      Yttria-stabilized zirconia (YSZ) hollow fiber membrane was prepared by a combined phase inversion/sintering method. The effects of YSZ content and sintering temperature on the microstructure and properties of the prepared hollow fiber membrane were investigated. The results show an asymmetric structure of YSZ hollow fiber membrane containing finger-like structure and sponge-like structure. The YSZ content impacted the ratio between finger-like structure and sponge-like structure, and sintering process caused a densification of microstructure. Under the conditions of m(YSZ):m(PSF):m(NMP)=5.0:1:4, sintering temperature of 1200 ℃, the pure water flux was 2.33 m3/(m2·h·MPa) and the bending strength was 134.5 MPa.
