硅酸铝陶瓷纤维过滤管的制备与表征

Preparation and Characterization of Alumina Silicate Fiber Filters

本文研究制备陶瓷纤维过滤管所用硅酸铝纤维、硅溶胶和水之间的最佳配比及最佳成型工艺参数。并对陶瓷纤维过滤管的气孔率、孔径以及抗弯强度进行测试,运用SEM对试样进行微观分析。研究确定的最佳配比是硅溶胶含量为68wt%,硅酸铝纤维含量为12wt%,水含量为20wt%,真空抽滤成型时最佳抽滤压力为0.08MPa,最佳抽滤时间为5min。

This paper has researched the best optimum ratio of alumina silicate fiber and silica sol in ceramic fiber filters. Then we will use porosity, aperture size, compressive flexural strength and SEM to evaluate different ratios and different technological parameters, which have effect on the properties of fiber filters. It was found that, the best ratio is silica sol content of 68wt%, alumina silicate fiber content of 12wt% and water content of 20wt%. In addition, we choose 0.08MPa and 5min as the best technological parameters for vacuum forming.
