【摘要】 利用不同浓度的油酸钠对硫化锌、硫酸钡和立德粉进行有机化改性 ,测定了改性样品的比表面、比孔容、平均孔半径的变化。研究了它们的吸附性质和润湿性质 ,结果表明 :比表面和比孔容随浓度的增加而减少 ,孔分布有所变化。对水和环己烷的润湿热呈递减趋势 ,改性样呈疏水性。更多还原

【Abstract】 In this article,sodium oleate with different concentration is used to modify Barium Sulfate,Zinc Sulfide and lithopone. The specific surface area,specific pore volume and the average pore radius of the same samples were determined. The wetting and adsorption properties of the same samples were studied.The results indicate:with increasing concerntration,1 the specific surface area and specific pore volume decreased,pore size distribution is changed.2 the heat of wetting in the water and cyclohexane decreased.更多还原
