Electric spark bombardment device for colloidal silver solution

Abstract

The electric spark equipment for colloidal silver solution is formed from high-frequency pulse generator, discharge gap automatic regulator, plastic tube and plastic impeller pump. The high-frequencypulse generator is connected with positive silver electrode and negative silver electrode by means of wires, the silver electrode holder is connected with positive silver electrode and machine seat, and the stepper motor is respectively connected with discharge gap automatic regulator and machine seat by means of ball screw. 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...

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.
