A research team led by Kim Jin Hyok, a researcher at the Nano Physics Engineering Institute, has developed an ozone generating tube of floating net electrode structure by covering a steel tube with nano-composite materials.
Ozone generation technology enables prevention of spread, infection and breeding of all kinds of infective viruses and sterilization of objects, air and water, etc. by ozone with marvelous germicidal power produced by physical devices without recourse to noxious chemical disinfectants.
An ozone generating tube works in a high voltage electric field. At the time of generating ozone, it gets hot and it has strong corrosiveness, so dielectric material for it must satisfy several properties (electric characteristics such as dielectric coefficient, coefficient of dielectric loss and electric strength, corrosion resistance, resistance to thermal shock, abrasion resistance, etc.) simultaneously.
To satisfy these characteristics, they decided to coat a steel tube with nano dielectric material in three layers. First, they newly developed undercoat borosilicate system glass ceramic material that satisfies the adhesive capacity with the steel tube and determined a suitable calcination process. Then, to develop a reasonable interfacial layer for ozone generation, they newly suggested a dielectric coefficient simulation algorithm of nano-composite materials based on a mixed state model and determined the mixing ratio of the materials.
On this basis, they established an appropriate process for production of ozone generating electrodes, produced a large capacity ozone generating tube, and proved the predominant properties.
An ozone generator equipped with these ozone generating tubes is very effective for sterilization of water, air and objects in several fields like foodstuff production and processing, interiors of buildings like hospitals, etc.
