【摘要】 以硅酸铝纤维和硅灰石为主要原料,硅溶胶为粘结剂,通过真空抽滤成型,低温干燥,制成短纤维过滤管。用SEM、XRD等测试方法对短纤维过滤管进行表征。结果表明:所制备的短纤维过滤管孔径在20～50μm;气孔率≥75%;具有良好的透气性能;抗热震性能强。更多还原

【Abstract】 With aluminum silicate fiber and wollastonite as the main raw material,silica sol binder,formed by vacuum filtration,low-temperature drying,the short fiber filter tube was prepared.The short-fiber filters were characterized by SEM,XRD and other tests methods.The results show that the prepared short-fiber filter tube diameter is 20-50 μm;porosity≥75%;with good permeability;strong thermal shock resistance.更多还原
