■ Nanobubble technology

There are many techniques for generating microbubble. Microbubble technology requires a lot of energy and time to generate nano bubbles, which is not economical. The Newman Tech’s nanobubble generation technology is different from existing technology. It is the principle that the shear force is applied to the flowing gas-liquid mixture and it is split into bubbles. Specifically, when the gas-liquid mixture moves in contact with a specific surface, a velocity gradient occurs due to the boundary layer effect, and the gas-liquid mixture is continuously split to a nano bubble.

Our nanobubble device generates nanobubbles without recycling, and the bubble size averages 160nm.

■ Nanobubble characteristic

Nanobubble is defined as diameters smaller than 1μm and larger than 1nm.
The smaller the bubble size slow floating, When it becomes nano-sized, it will not float and exist in the water.
As long as it exists in the water, it continuously delivers the substance in the bubble to the water.

Underwater behavior of nanobubble and microbubble

Nano bubbles reduce the surface tension of the bubble and water interface.
When nanobubbles are used with anionic surfactants, surface tension is further reduced.
Applying nano bubbles to cosmetics and pharmaceuticals using surfactants can reduce the adverse effects on the human body by reducing the amount of surfactant.
