AI Technical Summary

Benefits of technology

This patented technology describes different types of chemicals used together called hydrophobic or lipophilic substances like acids (or bases) and amines). These compounds help break up greasy materials more effectively when they come out onto surfaces during cleaning operations. They work better because they don't harm aquatic organisms if released over too long after being put inside them. Additionally, these chemistries have low environmental impact due their biodegradability making them ideal candidates for applications where recycling may occur. Overall, this new type of material helps create effective treatments against various contaminated areas including sea floors, rivers, ponds, etc., while minimizing negative side effects associated therewith.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the effectiveness of traditional oil-spilled dispersers used alone without any outside forces like wave action that help break up the oil layer quickly enough during cleanup efforts.

Abstract

The invention relates to a foaming type degradable water surface oil spill dispersant and a preparation method thereof, and belongs to the field of water body pollution prevention and control. According to the dispersing agent, a nonionic surfactant, an anionic surfactant, an adhesive, an acid agent, an alkaline agent and a filler are compounded according to a specific proportion, so that a largenumber of bubbles are generated after the dispersing agent is added into a water body, a rapid stirring effect is achieved, spilled oil can be rapidly dispersed and emulsified, and emulsified oil drops are small in particle size and good in dispersion effect. The active agent is a bio-based environment-friendly surfactant, so that the oil spill dispersant is environmentally friendly, is easy to degrade, causes little secondary pollution to a water area, and is suitable for various water surface environments such as oceans, lakes and the like.
