摘要：以泡沫镍薄片为载体,采用浸渍提拉工艺获得结构化硅胶吸附材料。采用场发射扫描电子显微镜(SEM)、傅里叶红外光谱仪(FT-IR)、X射线衍射仪(XRD)和多孔介质孔隙分析仪等对吸附材料表面形貌和结构进行表征。探讨浸渍次数、聚合氯化铝(PAC)溶液浓度、处理时间等条件对结构化硅胶吸附性能的影响。结果表明,结构化硅胶吸附材料表面呈均匀的蜂窝状结构,硅胶以中孔为主,孔径集中在5～15nm,所获得的结构化硅胶吸附材料具有较好的吸湿性能。在较少浸涂次数下,可获得转化率高的硅胶;随着PAC溶液浓度和处理时间的增大,硅胶的比表面积增大,孔径减小,比表面积最大为343m2/g。当PAC溶液溶度>10%或处理时间>2h时,结构化硅胶的比表面积呈现减小的趋势,吸湿性能降低。
Using nickel foam sheet as carrier, structured silica gel adsorption material was obtained by dipping and drawing process. The surface morphology and structure of silica gel were characterized by field emission scanning electron microscope （SEM）, Fourier transform infrared spectrometer （FT-IR）, X-ray diffraction （XRD） and porous media pore analyzer. The effects of impregnation times, concentration of polyaluminium chloride （PAC） solution and treatment time on the adsorption properties of silica gel were investigated. The results show that the surface of the structured silica gel adsorption material has a homogenous honeycomb structure. The silica gel is mainly mesoporous and its pore size is concentrated in 5-15 nm. The structured silica gel adsorption material has good moisture absorption property. The silica gel with high conversion rate can be obtained under the condition of less impregnation times. With the increase of PAC solution concentration and treatment time, the specific surface area of silica gel increases, the pore size decreases, and the maximum specific surface area is 343 m 2 /g. When the solubility of PAC solution is more than 10% or the treatment time is more than 2 hours, the specific surface area of structured silica gel decreases and the hygroscopicity of structured silica gel decreases.
