【摘要】 选取天然羽毛压缩物和复合聚酯纤维两种吸油毡,取4种油(2种原油和2种燃料油)进行短期风化,测量2种吸油毡对不同风化程度油的吸附量。分析结果发现,随着油风化程度的增强,天然羽毛对其中3种油的吸附量稍有增加,而对其中较轻原油的吸附量减小明显;复合聚酯纤维吸油毡对4种油的吸附量都增加,且增加幅度大于天然羽毛。原因是天然羽毛孔隙大材质厚,主要靠孔隙吸油,而聚酯纤维孔隙小且薄,表面粘附油的比重较大。对高密度油而言,风化程度越大,吸油毡越难靠孔隙对其渗透吸收,而表面粘附油占总吸附量的比重增加。可见,在应对不同风化程度油时,选取吸油毡须有针对性,才能最大限度地清除油污。更多还原

【Abstract】 Two kinds of absorbent felts and four kinds of oils(two kinds of crude oils and two kinds of fuel oils) are selected and adsorption amount has been measured after weathered with different degree. The results show that : for natural feather,adsorption amount of three kinds of oils increases slightly with weathering degree enhancing, while adsorption amount of lighter crude oil decreases significantly; for composite polyester fiber, adsorption amount of four kinds of oils increases with weathering degree enhancing and the increasing rate is greater than that of natural feather. The reason are: natural feather is thicker and has more pore spaces, while polyester fiber is on the contrary and the proportion of surface adhesive oil is more.For high density oil, the greater the weathering degree is, the harder to absorb it by pore penetration, so the proportion of sur-face adhesive oil increases. So in response to eliminate weathering oil with different degree,we shall select suited absorption felt to remove oil maximumly.更多还原
