摘 要
通过改变原料中造孔剂石油焦粉的含量,在870℃保温2 h烧结制备了开口孔隙率分别为39.2%,48.9%,54.4%的不同厚度多孔SiC陶瓷滤片,通过扫描电镜、能谱仪和X射线衍射仪等分析了其微观形貌和物相组成,并采用端滤法研究了厚度和开口孔隙率对水渗透通量的影响。结果表明:多孔SiC陶瓷滤片的孔隙分布均匀;随着厚度的增加,陶瓷滤片的水渗透通量呈线性下降,当厚度超过8 mm时,水将难以渗透;在相同厚度下,随着开口孔隙率的增大,水渗透通量迅速提高;开口孔隙率对水渗透通量的影响比滤片厚度的影响大。

Abstract
Porous SiC ceramic filters with different thickness and apparent porosities of 39.2%, 48.9%, 54.4%, respectively, were sintered at 870℃ for 2 h by changing the content of petrol coke powder (as the pore former). The micromorphology and phase composition of the ceramic filters were analyzed by the scanning electron microscope, energy dispersive spectroscope and X-ray diffraction. Moreover, the effects of thickness and apparent porosity on the water permeation flux of the ceramic filters were investigated by the dead-end filtration. The results show that the microscopic pores distributed uniformly in the porous SiC ceramic filter. With the increase of the filter thickness, the water permeation flux of the ceramic filter showed a linear decrease trend, and with the thickness over 8 mm it would be very difficult for water running through the filters. At the same thickness, with the increase of apparent porosity, the water permeation flux increased rapidly. The influence of the apparent porosity on the water permeation flux was bigger than that of the filter thickness.
