Abstract
The invention aims at providing a method for continuously preparing nano-powder of metal, alloy and oxides thereof, nitrides and the like, as well as dispersing liquid thereof in a graded manner by taking metal wires as raw material and adopting an electric explosion method. The invention adopts the following principle: the metal wires are gasified instantly under the action of high voltage electricity to form metal steam, and the metal steam is condensed into spherical metal nano-particles with complete surfaces when encountering cold. The metal nano-particles are delivered to two different collectors in a graded manner by working gas after passing through a filtering cabin, and enter the collecting tanks of the collectors to be mixed with medium. Uniformly dispersed dispersing liquid can be obtained by ultrasonic dispersion.
Description
One, technical field
The present invention relates to the classification Preparation equipment of nano-powder and dispersion liquid thereof.
Two, background technology
Nanosecond science and technology are the most dynamic, new sciences and technologies of the richest challenge of 21 century.Material in the nanoscale scope possesses the not available new features of a lot of macroscopic materials.In the knowledge of natural environment of nanoscale space, the innovation of carrying out technology and product is a kind of brand-new mode of production and working method, it and traditional working method are completely different, the raising of social progress, economic development, national security and living standards of the people are produced the far-reaching influence.Countries in the world have all given the attention of height, the development strategy that developed country formulates nanosecond science and technology one after another to nanometer technology.
Metal nano powder has the performances such as good electricity, magnetic, light, sound, has been widely used in material, electronics, information, Aeronautics and Astronautics, military project, medicine and other fields.At present having reached practical purposes has: catalyst, absorbing material, high active combustion agent, high explosive etc.
The method of producing metal nano mainly is Physical, and the metal nano powder surface energy of Physical preparation is high, and is active large, easily disperses.But there is simultaneously energy consumption large, yields poorly the difficulties such as poor stability.Domestic more employing discharge-induced explosion method wiry is produced nano metal powder at present, obtained certain progress in energy utilization rate and output, but this kind method generally can only be used for producing dried nano metal powder, is difficult to produce the dispersion liquid that is kept in the liquid medium (the especially large medium of volatility).If add again in the liquid medium after the metal nano powder passivation that will produce, easily introduce impurity, and nano-powder is after passivation, surface energy affects the performance of material with lossy, the dispersion liquid that especially purity of material is had high requirements.
In addition, the discharge-induced explosion wire prepares metal nano powder equipment and be prone to large flakelike powder and light-weight metal silk broken end in collector, application number is that 200810050836.7 patent adopts the screen pack of belt scraping plate to address this problem, but long-term the use easily makes screen pack stop up.
Three, summary of the invention:
The purpose of this invention is to provide a kind of wire that utilizes and be raw material, adopt the method for discharge-induced explosion, prepare continuously, scalably the method for the nano-powder such as metal, alloy and oxide, nitride and dispersion liquid thereof.
Principle of the present invention is: wire is under the effect of high-tension electricity, and the moment gasification forms metallic vapour, and metallic vapour is met condensation and formed the complete spherical metal nano particle in surface.Metal nano powder is transported to 2 different collectors through behind the filter position by the working gas classification, enters in the collecting tank of collector, mixes with medium.Disperse by ultrasonic wave, obtain finely dispersed dispersion liquid.
The object of the present invention is achieved like this:
High high-voltage dc pulse power, wire feeding device, high-pressure gasified chamber, filtering cabin, one-level dispersion collecting chamber, secondary dispersion collecting chamber, wind pushing mechanism, the vacuum plant of expanding of this equipment
