Coalescence fiber material for oil-water separation

Abstract

The invention relates to a coalescence fiber material for oil-water separation. A plurality of variable-diameter structures which are periodically and uniformly distributed are formed on the coalescence fiber material in the length direction of cellosilk at intervals, the diameter of the intermediate position of the variable-diameter structure is the largest, and the diameter gradually decreases toward both sides. The variable-diameter structure is of a spindle structure. Due to the existence of the periodic variable-diameter structure, the moisture adsorbed on the surface can be quickly collected under the action of surface tension. A filter material woven by the coalescence fiber material provided by the invention can capture tiny water droplets in an oil-water mixture and realize rapidcollection, so that the moisture can quickly form large droplets to achieve demulsification; the structure and the preparation method are simple, and the separation efficiency is high, and the application prospects are wide in oil-water separation and other aspects.

Description

technical field [0001] The invention relates to a coalescing fiber material for oil-water separation that uses interface mechanical properties to improve the water-catching and gathering performance of the material. By optimizing the surface structure of the base fiber material, the oil-water interface force is used to promote the aggregation of droplets, which can realize High-speed, economical and reliable emulsion breaking.
