Embodiment 1

[0032] Take a red copper wire with a length of 10 mm and a diameter of 0.46 mm, and clean the copper wire with 2 mol / L hydrochloric acid solution, absolute ethanol, and distilled water in ultrasonic vibration for 3 minutes to obtain a clean copper wire. Mark the copper wire evenly into 2 sections, the second section of the copper wire is fully inserted into the synthetic rubber to be protected. Then put the first section of the copper wire upright into an electrolytic cell with a concentration of 2mol / L sodium hydroxide solution, the first section of the copper wire is completely immersed in the sodium hydroxide solution, and the copper wire is used as the anode. Graphite is used as the cathode for electrolysis, and the electrolysis voltage is constant at 20V. During the electrolysis process, use a micro-syringe pump to draw out the electrolyte at a rate of 1mm / min. When the liquid level of the electrolyte is slightly lower than the upper surface of the solid glue, stop the ex...

Embodiment 2

[0035]Take a red copper wire with a length of 18 mm and a diameter of 0.5 mm, and clean the copper wire with 2 mol / L hydrochloric acid solution, absolute ethanol, and distilled water in ultrasonic vibration for 3 minutes to obtain a clean copper wire. The copper wire is evenly marked into 3 sections, and the second and third sections of the copper wire are fully inserted into the synthetic rubber to be protected. Then put the first section of the copper wire upright into the electrolytic cell with a concentration of 1mol / L hydrochloric acid solution, the first section of the copper wire is completely immersed in the hydrochloric acid solution, the copper wire is used as the anode, and the graphite is used as the cathode. Electrolysis, the electrolysis voltage is constant at 10V. During the electrolysis process, use a micro-injection pump to draw out the electrolyte at a rate of 0.5mm / min. When the liquid level of the electrolyte is slightly lower than the upper surface of the ...

Abstract

The invention discloses a multi-stage conical copper wire for effectively collecting mist, as well as a preparation method and application thereof. The multi-stage conical copper wire includes 2-10 sections, wherein each section has a length of 5-15mm and a conical angle of 1-10 degrees, and has a small endup conical structure; multiple sections of the copper wires are sequentially connected; and the diameter of each section is 0.3-1mm. According to the method, multiple sections of conical copper wires are prepared by simultaneously applying an external isolated protection method and a gradient electrochemical corrosion method, multiple sections of conical copper wires are applied to mist collection, and droplets gathered from mist on the copper wires can be effectively transported for a long distance, so that the surface updating rate of the copper wires can be improved, and the mist collection speed can be greatly improved.

Description

technical field [0001] The invention relates to mist collection, in particular to a multi-segment tapered copper wire for efficiently collecting mist and its preparation method and application, belonging to the technical field of chemical bionics. Background technique [0002] Water is a resource that all living things on earth depend on for survival, but the crisis of water resources has become a worldwide problem. Although the amount of water on the earth is huge, fresh water resources only account for 2.5% of the total water. Among them, 87% of the fresh water resources are distributed in the Antarctic, Arctic, alpine glaciers and permafrost snow, so the fresh water resources that can be directly used by human beings for production and living account for 0.26% of the total water in the world. At the same time, due to the uneven distribution of water resources and the pollution of water resources caused by human production activities, the fresh water resources that people...
