摘 要: 针对现阶段存在的油泄露对于环境的污染问题,提出了一种新型纺丝技术,并利用该技术制备了用于吸附油污的纺丝件。通过改变喷射距离和纺丝件形状的方法制备出几种不同的纺丝件,研究不同喷射距离对于孔隙率的影响规律以及孔隙率和纺丝件形状变化对于不同油吸附能力的影响,最后研究了纺丝件的重复使用性能。结果发现,高孔隙率纺丝件疏水亲油性更好、吸油倍率更高、吸油速率更快,吸油倍率随纺丝路径周期增大到一定数值后趋于不变,重复吸放油5次后仍可达到初次吸油倍率的65%。因此,该技术在吸油领域有一定的应用前景。
关 键 词: 机械制造工艺与设备;环境;聚乳酸;纺丝件;吸附油污;吸油倍率

Abstract: In order to solve the problem of environmental pollution caused by oil leakage at the present stage, a new type of spinning technology was proposed, and the spinning parts used for oil adsorption were prepared by using this technology. Several different spinning parts were prepared by changing the injection distance and the shape of the spinning parts. The influence of different injection distance on the porosity and the influence of the porosity and the shape of the spinning parts on the different oil adsorption capacity were studied. Finally, the re-use performance of the spinning parts was studied. The results showed that the spinning parts with high porosity had better hydrophobicity, higher oil absorption ratio and faster oil absorption rate. The oil absorption ratio tended to be constant when the spinning path period increased to a certain value, and the oil absorption ratio could still reach 65% of the initial oil absorption ratio after repeated oil suction and drainage for 5 times. Therefore, this technology has a certain application prospect in oil absorption field.
Key words: technology and equipment of machinery manufacture; environment; polylactic acid; spinning parts; adsorption of oil; oil absorption ratio
