Preparation and properties of two kinds of hydroxyapatite filters, filter cloths and porous ceramics, were investigated. The filter cloth was prepared by depositing nanosize ceramic hydroxyapatite on a cotton fabric. The porous ceramic with pore size of several micrometers or less was fabricated by using water soluble starch as a pore former, and its permeability was controlled by adding insoluble starch. Bacterial filtration tests showed that the six-layer filter cloth can clear bacteria effectively, and the porous ceramic can remove 100% of the bacteria. Both the filter cloth and the porous ceramic can be used to clear or separate microbes.
研究了两种羟基磷灰石过滤器、滤布和多孔陶瓷的制备及其性能。滤布是通过在棉织物上沉积纳米级陶瓷羟基磷灰石制备而成。以水溶性淀粉为造孔剂制备了孔径为几微米或更小的多孔陶瓷,并通过添加不溶性淀粉来控制其渗透性。细菌过滤试验表明,六层滤布能有效除菌,多孔陶瓷能去除100%的细菌。滤布和多孔陶瓷均可用于清除或分离微生物。
