The Study of Highly Oil Absorption Polyurethane Foam Material and Its Application in the Emergency Disposal of Hazardous Chemicals

摘要

This paper introduced a kind of oil absorption polyurethane foam (PUF) material, which had good absorption on a variety of liquid hazardous chemicals. The absorption rate of this material while absorbing crude oil can reach 40g / g or more and the absorption rate to xylene is 49.9g / g. In addition, this paper also discussed the relationship among the cell opening rate, volume availability and the oil absorption rate of the foam material, comparing with oil absorption felt, the commonly used absorption materials. Researchers observed the microstructure of PUF by the scanning electron microscope, discussed its oil absorption mechanism and analyzed its emergency disposal in the leakage accident of hazardous chemicals.
