AI Technical Summary

Benefits of technology

This patented technology involves combining two methods: one by applying coatings or modifying existing materials for better absorption properties while another improves its ability to separate oily liquids from other substances like water. It also includes adding certain chemical agents that improve the interaction between these particles and liquid droplets during their formation process. Overall this results in efficient separations without causing damage to sensitive components such as electronic devices inside equipment.

Problems solved by technology

This technical problem addressed in this patents relates to developing efficient ways to remove unwanted substances like greasy dirt particles from crude oil waters containing organics called bitumen. Current techniques involve expensive equipment and processes, leading to potential issues related to their impact upon environment health concerns. Therefore there exists a demand for effective solutions involving new types of polymer materials capable of efficiently removing these harmful components.

Abstract

The invention discloses a preparation method and application of a super-hydrophobic glass fiber composite oil-water separation material, and the preparation method of the material comprises the following steps: dissolving basic cupric carbonate in an alkali solution to obtain a mixed solution I; impregnating a glass fiber felt in the mixed solution I to obtain a CuO glass fiber felt; dissolving polydimethylsiloxane in an organic solvent to obtain a mixed solution II; and soaking the CuO glass fiber felt in the mixed solution II, and carrying out high-temperature curing treatment to obtain the super-hydrophobic glass fiber composite oil-water separation material. The super-hydrophobic glass fiber composite oil-water separation material is prepared by loading a copper oxide crystal and a polydimethylsiloxane (PDMS) solution onto the surface of a glass fiber composite material by using a hydrothermal deposition method and an excessive impregnation method respectively. Due to ultrahigh hydrophobic and oleophylic properties and a superposable combination mode, the material has a good demulsification effect on various emulsified oil, and can be widely applied to oil-water separation operation.
