Problems solved by technology
[0003] 1. Chemical method: The leading product of this process is silver nitrate, which is a silver salt (compound) produced by combining nitric acid with silver (Ag). The silver (Ag) particles are colloidal crystals, dissolved in water, and belong to Micro-particle level, this process method is highly toxic and serious public hazards
[0004] 2. Vacuum physical method: resistance heating inert gas evaporation method, laser vacuum evaporation method, hydrogen arc plasma vacuum sputtering method, nano-scale silver (Ag) particle powder can be prepared through the above-mentioned process equipment, and the particle length is 5~ 60nm, but the equipment manufacturing is complicated, the investment is large, the production cost is high, and the product is expensive
[0005] In the above-mentioned methods, although silver (Ag) microparticles can be produced, they affect the popularization and development of silver (Ag) particle technology because of their hindrance to environmental protection and expensive economic investment.

Embodiment Construction
[0027] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0028] according to figure 1 , figure 2 , image 3 It can be seen that it is composed of a high-frequency pulse generator 1, an automatic discharge gap regulator 4, a plastic tube, and a plastic impeller pump. The high-frequency pulse generator 1 is connected to the positive silver electrode and the negative silver electrode through wires 2 and 3, because the high-frequency pulse The power supply 1 and the automatic discharge gap regulator 4 are prior art (so not described). The sawtooth wave generated by the high-frequency pulse generator 1 is added to the two ends of the positive and negative silver electrodes through the wires 2 and 3. The silver electrode clamp is connected with the positive silver electrode and the silver electrode plate motion transmission system base 5, and the stepping electrode passes through the ball wire. The rods are respectively conne...

Said invention is simple in structure, convenient in operation and low in cost.
Description
technical field [0001] The invention relates to a colloidal silver (Ag) solution preparation device, more particularly to an electric spark bombardment device for a colloidal silver solution. Background technique [0002] There are currently two industrial preparation methods for preparing silver (Ag) into microparticles and nanoscale particles, namely: chemical method and vacuum physical method. [0003] 1. Chemical method: The leading product of this process is silver nitrate, which is a silver salt (compound) produced by combining nitric acid with silver (Ag). The silver (Ag) particles are colloidal crystals, dissolved in water, and belong to Microparticle level, this process method is highly toxic and serious public hazards. [0004] 2. Vacuum physical method: resistance heating inert gas evaporation method, laser vacuum evaporation method, hydrogen arc plasma vacuum sputtering method, nano-scale silver (Ag) particle powder can be prepared throug...
