Abstract
In this paper, PVA electrospun nanofiber was prepared on the surface of three different automobile engine oil filtration materials including polyester nonwoven, glass fiber nonwoven, and cotton pulp filtration paper. It was found that the substrate of cotton pulp filtration paper and the nanofiber layer had better adhesive effect. Then we A comparison of fiber diameter, pore diameter, filtration accuracy and pressure drop between the cotton pulp paper and nanofiber composite filtration material was then made. The results show that the nanofiber composite material had smaller pore diameter and filtration accuracy, higher pressure drop, and better oil filtration property. Additionally, the difference of pressure drop between the substrate and nanofiber composite material increased with increasing flow rate of experimental oil. The goal of this paper was use the electrospun nanofiber in the automobile engine oil filtration.
