Embodiment 1

[0027] The microstructure and microchannel graphics of the two-layer chip of the centrifugal microfluidic chip were designed and drawn by computer-aided design software. The microstructure and microchannel of the two-layer disc-shaped polymethyl methacrylate (PMMA) chip were processed and prepared by the numerical control CNC system, and the chips of each layer were cleaned with tap water and distilled water, and the remaining fingerprints, oil stains and other stains on the chip surface were wiped with ethanol . On the double-sided adhesive film, the required microstructures and microchannels were processed with a cutting machine. The two-layer chip is carefully aligned, bonded, and pressure-sealed to make an oil-water separation microfluidic chip. Connect the oil-water solution storage tank to the sample injection hole, use the liquid difference to add the oil-water mixed solution to be separated, apply an electric field, the oil-water mixed solution will rapidly break the ...

[0029] The microstructure and microchannel graphics of the two-layer chip of the centrifugal microfluidic chip were designed and drawn by computer-aided design software. The microstructure and microchannel of the two-layer disc-shaped polycarbonate (PC) chip were processed and prepared by the numerical control CNC system. The chips of each layer were cleaned with tap water and distilled water respectively, and the remaining fingerprints, oil stains and other stains on the surface of the chip were wiped with ethanol. On the double-sided adhesive film, the required microstructures and microchannels were processed with a cutting machine. The two-layer chip is carefully aligned, bonded, and pressure-sealed to make an oil-water separation microfluidic chip.

Abstract

The invention relates to an oil-water-separation micro-fluidic chip and a preparation method thereof. A micro-structure and a micro-channel are arranged on the surface of the micro-fluidic chip, and the left side and the right side of the micro-channel respectively carry out hydrophilic and oleophylic modification. Under the action of an electric field, an oil-water mixed solution is demulsified, water moves to the hydrophilic side, oil moves to the oleophylic side, and finally oil water-separation is realized. The oil-water-separation micro-fluidic chip is mainly applied to the related fields of transformer oil, turbine oil of power plants, mrine oil spill processing, failed oil of oil fields, oil spill of offshore drilling platforms, advective oil of steel mills, a lot of oily wastewater of oil refineries and the like. The micro-fluidic chip realizes the rapid demulsification and rapid separation of the oil-water mixed solution, has the characteristics of convenience, economy, rapidness and high efficiency, and provides a new analysis technique for the field of oil-water separation.

Description

technical field [0001] The invention relates to a microfluidic chip for oil-water separation and a preparation method thereof. The surface of the microfluidic chip has microstructures and microchannels, and the left and right sides of the microchannel are respectively modified to be hydrophilic and lipophilic. , the oil-water mixed solution undergoes demulsification, water moves to the hydrophilic side, oil moves to the lipophilic side, and finally realizes oil-water separation. It is mainly used in transformer oil, turbine oil in power plants, offshore crude oil spill accident treatment, oil field landing oil, offshore Oil slicks on drilling platforms, advective oil in steel mills, large amounts of oily wastewater from refineries and other related fields. Background technique [0002] In the late 1980s, in order to establish a culture system more similar to the in vivo environment and make the in vitro environment as consistent as possible with the in vivo environment, so t...
