Science and Technology Daily Special Report on Air Negative Oxygen Ion Generating Agent in Our Hospital

With the improvement of living standards, people pay more and more attention to the environment, especially air quality. In response to this demand, the Advanced Manufacturing Joint R & D Center of Tianjin High-end Equipment Research Institute of Tsinghua University has successfully developed an air negative oxygen ion generator after painstaking research. The technology uses natural materials. After simple spraying construction, it can continuously produce high concentrations of negative oxygen ions in spaces such as homes, offices, and cars, and increase the release of negative oxygen ions in indoor spaces to more than 6000 per cubic centimeter., Valid for more than ten years. Science and Technology Daily has made a special report on this technology in our hospital. The following are the specific reports.

Artificial manufacturing without energy consumption of negative oxygen ions

Science and Technology Daily News (Reporter Chen Xi) A few days ago, the team of Dr. Zhang Xiaohao, director of the Advanced Manufacturing R & D Center of Tianjin High-end Equipment Research Institute of Tsinghua University, successfully developed a medical and health-care high-concentration negative oxygen ion generator, which can be sprayed on the wall. A uniform and dense nanoparticle layer is formed on the wall, so that the indoor wall can stably and long-term release high concentrations of small particle size negative oxygen ions. Attaching nanoscale tourmaline powder evenly and densely on the surface of the object to maximize its effect is a key point of this technology. 7 papers related to the results have been published by the Journal of Physics, Microfluidics and Nanofluidics, etc. SCI journals included.

"The molecules in the air are ionized, producing free electrons. Most of the free electrons are taken by oxygen, forming negative oxygen ions." Zhang Xiaohao introduced that negative oxygen ions have excellent purification and dust removal effects, and enjoy the reputation of "Vita oxygen" and "longevity element" in the medical community.

"The content of negative oxygen ions in the city is very low, and the indoor is lower. To effectively increase the concentration of negative oxygen ions in the room, we can only 'artificial manufacturing '." Zhang Xiaohao said, "We use natural polar material-nanoscale tourmaline powder as the core raw material to develop a high-concentration negative oxygen ion generating agent. Free electrons are generated through a pure physical process such as ionization of air by tourmaline powder, thus obtaining negative oxygen ions."

"We have also used special additives, using the principle of molecular self-assembly, so that the tourmaline powder can form a more uniform and dense distribution on most walls, effectively improving the contact surface of the tourmaline powder with the air, thus greatly improving the effect of the tourmaline powder to ionize the air. This negative oxygen ion generator can be widely used on walls, paints, fabrics, wood, plastics, leather and other common surfaces." Zhang Xiaohao said.

It is reported that this technology is the first in China, filling the gap of colorless and transparent high-efficiency negative ion generation material. Compared with the widely used high-pressure ionization technology, the process of generating negative oxygen ions does not require energy consumption, the proportion of small particle size negative oxygen ions is high, and the problem of ozone associated with high-voltage power technology is effectively avoided.
