- Nanobubbles produced according to the present invention are characterized by being present in the solution for a long period of one month or longer.
- the solution containing nanobubbles depends on the nature of the gas contained in the nanobubbles, It has a physiological activity effect on living organisms, killing and inhibiting growth of microorganisms such as bacteria and viruses, and a chemical reaction with organic or inorganic substances.
- nanobubbles produced by the nanobubble production method according to the present invention have a particle diameter of less than 200 nm as shown in the particle size distribution in FIG. Nanobubbles produced by the method for producing nanobubbles according to the present invention continue to exist in an aqueous solution for a long period of 1 month or longer.
- the storage method of the aqueous solution containing nanopable is not particularly limited, and nanobubbles disappear for more than a month even if stored in a normal container.
- the microbubbles in the aqueous solution have a surface potential depending on the pH of the aqueous solution, as shown in Fig. 2.
- This is the hydrogenation of water at the gas-liquid interface.
- This charge has a constant value regardless of the bubble diameter because it maintains an equilibrium condition with respect to the surrounding water.
- the electrostatic force is applied by the band mi on the surface, so the ions with opposite signs are attracted to the vicinity of the gas-liquid interface.
- Figure 3 shows the change in surface charge when the bubble diameter is reduced from 25 ⁇ m to about 5 m in 10 seconds. According to Fig. 3, the bubble diameter is small.
- ⁇ ⁇ ⁇ is the degree of pressure rise
- ⁇ is the surface tension
- D is the bubble diameter.
- the gas inside the self-pressurized microbubbles dissolves in water according to Henry's law. Therefore, the bubble diameter is gradually reduced, and the internal pressure increases as the bubble diameter is reduced, so that the bubble diameter reduction speed is accelerated.
- bubbles with a diameter of 1 m or less are completely dissolved almost instantaneously. In other words, nanobubbles exist only very momentarily.
- microbubbles having a diameter of 150 m are rapidly reduced by physical stimulation.
- Ions such as iron, manganese, force ruthenium, sodium, magnesium, and other minerals are used so that the electrical conductivity in an aqueous solution containing microbubbles is 300 z SZ cm or more.

- This electrostatic repulsion force acts on ions of the same sign existing on the opposite surface of the sphere by increasing the curvature of the sphere as it shrinks in a spherical microbubble. This is the electric power.
- Bubble diameter of nanobubbles varies depending on the concentration and type of electrolyte ions, but as shown in Fig. 1, the characteristics of nanobubbles are less than 200 nm.
- a very strong electric field is formed by the concentrated surface charge. This strong electric field has a powerful effect on the gas inside the bubble and the surrounding aqueous solution, and has a physiological activity effect, bactericidal effect, chemical reactivity, etc.
- Fig. 4 shows the mechanism of the stable existence of nanopables.
- an extremely high concentration of electric charge is concentrated at the gas-liquid interface, so that the electrostatic charge acting between the opposite sides of the sphere is electrostatic.
- the repulsive force prevents the sphere (bubble) from contracting.
- inorganic mist mainly composed of iron and other electrolyte ions is formed around the bubbles, which prevents the escape of the internal gas.
- the shell of the surfactant and organic matter Because it is different from the shell, the shell itself easily collapses due to the release of the charge around the bubble that occurs when nanobubbles come into contact with other substances such as Itoda. The shell collapsed Now, the gas contained inside is easily released into the aqueous solution.
