Problems solved by technology

But because carbon nanotubes are very small and very light, there is a kind of van der Waals force between carbon nanotubes, which makes them adsorb each other and become a group. It is difficult to overcome the suction force between them and make them Distribute evenly into paint or oil
Although the laboratory can do it manually, it is difficult to carry out industrialized mass production, which hinders the promotion and use of carbon nanotubes

Embodiment Construction

[0009] In the specific example shown in the figure, the equipment for uniformly distributing carbon nanotubes in the liquid medium has two-stage liquid flow pulling devices, and each stage of liquid flow pulling devices includes a storage tank 1 for storing the mixed solution of carbon nanotubes and liquid medium. Injection device 2, atomization collection barrel 3, storage tank has exhaust port 1.1 and discharge pipe 1.2 provided with valve 4, and stainless steel wire cluster is plugged in exhaust port 1.1 for liquid-gas separation. The discharge pipe 1.2 is connected to the pipeline of the injection device 2. The injection device has a nozzle 2.1 and a pipeline 2.2 with a rough inner wall surface. The nozzle 2.1 is inserted in the pipeline 2.2 and is coaxial with the pipeline. The discharge port is connected, and the discharge port of the pipeline 2.2 is connected with the atomization collection barrel 3, and the atomization collection barrel is provided with an axial grid pl...

Abstract

The method for uniformly distributing nano carbon tubes in liquid medium includes the following steps: stirring and mixing nano carbon tubes and liquid medium, placing them into a storage tank with outlet, connecting the outlet with pipeline with rough pipe wall of spray device, utilziing centrifugal pump to make identicial liquid medium form high pressure liquid flow and feeding it into spray device, making the high-pressure liquid flow sprayed out by center nozzle of spray device carry the mixed liquor to implement full mixation and atomization in the pipeline with rough pipe wall, then feeding the above-mentioned material into atomization collecting cylinder, making the collected liquid flow into second storage tank whose outlet is connected with second spray device, at the same time feeding the above-mentioned high-pressure liquid flow into second spray device.

Description

technical field [0001] The invention relates to a method and equipment for uniformly distributing carbon nanometer tubes in a liquid medium. Background technique [0002] Countries have invested a lot of technical force in the development of carbon nanotubes, because it has many excellent properties, including infiltrating carbon nanotubes in paint, which can double the adsorption force of paint, and infiltrating carbon nanotubes in lubricating oil, which can improve lubrication. Oil properties, etc. But because carbon nanotubes are very small and very light, there is a kind of van der Waals force between carbon nanotubes, which makes them adsorb each other and become a group. It is difficult to overcome the suction force between them and make them Distribute evenly into paint or oil. Although the laboratory can do it manually, it is difficult to carry out industrialized mass production, which hinders the promotion and use of carbon nanotubes. ...
