| 摘 要： | 讨论了玄武岩纤维复合过滤性能和微孔尺寸,打浆度、玄武岩纤维含量等因素的相互关系.结果表明,滤材的平均孔径与其含量能呈很好的相关性.通过扫描电镜观察,提出了复合滤材的结构模型.不同打浆度和玄武岩纤维含量下,孔径与过滤速度的关系研究表明,最小、最大和平均孔径与过滤速度的变化趋势是一致的.复合滤材的过滤速率随孔径的降低而变小,孔径降低到一定的程度后,过滤速率降低缓慢.同时分析了颗粒在介质上的滞留方式导致过滤性能下降的原因.复合过滤材料的热性能研究表明,过滤性能的破坏主要是由木纤维的热老化造成的.

| Abstract: | Correlations between filtration performance and microporous size,beating degree,content of basalt fibers,etc.were discussed.The results showed that mean porous size of filtration materials and content of basalt fibers was of commendable interdependency.Construction model of composite filtration materials was presented based on observations of scanning electron microscopy.Researches for correlativity between porous size and filtration rate declared that their variation trend average at average porous size le... |
