The working principle of wire electric explosion method powder production equipment: in a certain medium (such as inert gas, water, etc.) environment, when the strong pulse current passes through the conductor wire, the physical state of the conductor material itself changes sharply, rapidly vaporizes, and then condenses into nucleation, so as to obtain a certain particle size range of powder.
Application
Wire electric explosion method powder production technology is widely used in producing a variety of nano powder materials, according to the principle of electric explosion technology, the material used for electric explosion must be a good conductive material, so the general metal, alloy, intermetallic compounds and metal oxides can be made powder by electric explosion method.
Overview
The working principle of wire electric explosion method powder production equipment: in a certain medium (such as inert gas, water, etc.) environment, when the strong pulse current passes through the conductor wire, the physical state of the conductor material itself changes sharply, rapidly vaporizes, and then condenses into nucleation, so as to obtain a certain particle size range of powder.
Advantages
Wire electric explosion method powder production equipment is mainly used to produce various nano-powders.
Wire electric explosion method powder production technology has the following advantages:
① High efficiency of energy conversion: It is easy to convert electrical energy into heat energy by relying on the resistance of the wire in the discharge circuit.
② The particle size distribution of the prepared powder is more uniform and high purity: pulse discharge can gasification the entire metal wire at the same time, the gasification effect is more uniform, and the surrounding environmental media can be controlled to ensure the high purity of the nanoparticle (the purity of metal nanomaterials can reach 99%).
③ Adjustable process parameters: the particle size can be effectively controlled by adjusting the capacitance, charging voltage and the size of the explosive wire.
④ Strong versatility: the electric explosion method can prepare nano powder materials with a wide particle size range.
