摘　　要：对纤维素酶作用下的白水混合微细胶黏物在不同黏附材料表面的多重黏附特性及其规律进行了研究。结果表明,纤维素酶具有分散作用,可使白水混合微细胶黏物颗粒的尺寸明显减小,大颗粒(0.5~10μm)分散成小颗粒(0.2~0.5μm),总体积减小,颗粒数量增加。多重黏附材料表面的亲/疏水性影响其黏附特性,且不同亲/疏水性表面的黏附作用顺序不同,影响纤维素酶作用下白水混合微细胶黏物的净化效率。其中,铜片-棉布的净化效率最高,为68.6%;棉布-泡沫铜的净化效率较低,为48.1%;泡沫铜-棉布的净化效率最低,仅13.4%。In this study,the multiple adhesion properties and law of mixed microstickies from whitewater with cellulase treatment on different adhesion materials were explored.The results showed that cellulase had a dispersing effect,which could make the size of mixed microstickies particles from white-water decrease significantly,and the large particles(0.5~10μm)were dispersed into small particles(0.2~0.5μm),the total volume decreased and the number of particles increased.The hydrophilicity/hydrophobicity of the surface of multiple adhesion materials affected the adhesion properties,which affected the efficiency of adhesion purification of mixed microstickies with cellulase treatment.The highest purification efficiency of 68.6%was from copper sheet-cotton cloth;the lower purification efficiency of 48.1%was from cotton cloth-copper;and the lowest purification efficiency of 13.4%was from copper foam-cotton sheet.
