Oil Sorption Performance of Bamboo Pulp Fiber Powder

抄録

The oil sorption capacity, oil retention capacity and oil release property of bamboo pulp fiber powder were characterized, which may extend the applications of bamboo pulp fiber powder in the field of mechanical lubrication. The oil sorption ratio of the bamboo pulp fiber powder to mineral oil was 8.48 g/g, and the oil sorption ratio to PAO synthetic oil was 9.02 g/g. The oil retention ratio of bamboo pulp to mineral oil was 44.2%, and the oil retention ratio to PAO synthetic oil was 29.0%. The oil release ratio increased with the increasing drying time of all samples. When the oil sorption ratio was 3g/g, the oil release ratio has linear relationship vs. drying time at all drying temperatures. The initial oil release temperature was increased as the increasing oil sorption ratio of the fiber powder. The factors that influenced the oil sorption or release properties of bamboo pulp fiber powder such as surface morphology, the surface energy and temperature were also analyzed.
