Because negative ions have excellent purification and dust removal, sleep improvement, antioxidant and other effects, they can be widely used on the surfaces of walls, wood, leather and other objects.
Negative oxygen ions are known as "air vitamins" and play an indispensable role in human health. The World Health Organization uses the "negative oxygen ions" content in the air as an important indicator to measure whether the air quality is fresh. one. Negative oxygen ions can effectively remove dust, sterilize and promote human health. In recent years, as the country has been making great efforts to control environmental pollution and create "lucid waters and green mountains" for the people, artificially generated negative oxygen ion products have gradually formed a huge market demand.
A few days ago, the team of Dr. Zhang Xiaohao from Jiujiang Advanced Manufacturing Joint R&D Center of Tianjin High-end Equipment Research Institute of Tsinghua University successfully developed Tsingda’s excellent oxygen microparticle size negative oxygen ion generator, which fills the gap of colorless and transparent high-efficiency negative ions. Create a blank for the material.
This technology uses natural materials. After simple spraying construction, it can continuously produce high concentrations in spaces such as homes, offices, and cars. Negative oxygen ions, this technology is the first in China and has obtained a national patent. ?Zhang Xiaohao, director of the Jiujiang Joint R&D Center of the Institute of Advanced Technology of Tsinghua University: "The materials selected are non-toxic and harmless. They are natural nano tourmaline powder to generate this kind of negative oxygen ions. Our highlight is actually that ours is very long-lasting. As long as the nanoparticles do not fall off on the surface, it is basically a long-term and permanent release process."
Currently, this scientific and technological achievement has been mass-produced in the Lianxi District Industrial Park. ?
Zhang Xiaohao, director of the Jiujiang Joint R&D Center of Tsinghua University’s Institute of Advanced Technology: “At present, our eight agents combined have orders worth several million. . Because it has been less than two years since we officially started promoting it, the effect is still quite obvious.”
With the improvement of people’s living standards in our country, people are paying more and more attention to health. Negative oxygen ions are increasingly recognized by people for their air purifying and health care functions. However, the products currently on the market for artificially producing negative oxygen ions are of mixed quality, and there is an urgent need for standardized product technical indicators and detection methods in the industry. ?
On March 13, the “Release of Industry Standards for Negative Oxygen Ion Products and Implementation Meeting of Tsinghua University’s Optimal Oxygen Scientific and Technological Achievements” was held at the Advanced Manufacturing Joint R&D Center of Tianjin High-end Equipment Research Institute of Tsinghua University. China International Science and Technology Promotion Huima Lihao gave a detailed interpretation of the "Technical Indicators and Inspection Methods of Artificially Generated Negative Oxygen Ion Products". ?"Air negative ions, also known as negative oxygen ions, refer to oxygen ions that have one or more negatively charged electrons. It is formed by combining oxygen molecules in the air with free electrons." Research on high-end equipment in Tianjin, Tsinghua University Dr. Zhang Xiaohao, director of the Institute's Advanced Manufacturing Joint R&D Center, said that negative ions have excellent effects in purifying dust, reducing the harm of second-hand smoke, improving the prevention of respiratory diseases, improving sleep, anti-oxidation, anti-aging, scavenging free radicals in the body, and reducing blood viscosity. , enjoys the reputation of "vitamin oxygen", "longevity factor" and "air vitamin" in the medical community. ?The World Health Organization regards the "negative oxygen ion" content in the air as one of the important indicators to measure whether the air quality is fresh.
The World Health Organization stipulates that the standard concentration of negative ions in fresh air should be greater than 1500 ions/cm2; an environment with a concentration of 4000 ions/cm2 has health care effects. However, the typical value of negative ion concentration in cities is only 80-160 ions/cm2, and even less indoors. ?In order to increase the content of negative oxygen ions in the air, a variety of artificially produced negative oxygen ion products have emerged, and the market has also expanded. But at the same time, the lack of industry standards is detrimental to the healthy development of this industry.
To this end, the Tianjin High-end Equipment Research Institute of Tsinghua University took the lead and joined forces with Jiangxi Tsingda High-end Technical Services Co., Ltd., CSSC Jiujiang Marine Equipment (Group) Co., Ltd., Huaxia Travel Co., Ltd., Sunshine City (Holdings) Group, and China Jinmao Holding Group Co., Ltd. The company and other leading enterprises in the industry jointly drafted and formulated the "Technical Indicators and Inspection Methods for Artificially Generated Negative Oxygen Ion Products", which is also the first release of industry standards for artificially generated negative oxygen ion products. ?
Ma Lihao introduced that the standard focuses on the principle of negative oxygen ion generation, classification of artificial negative oxygen ion products, release limits, safety during use, inspection methods, harmful substance limit detection and the use process Safety testing has been elaborated and stipulated in detail. The release of the standard is conducive to promoting the standardization and healthy development of the negative oxygen ion product industry, and for the "marketization", "civilianization" and "lifestyle" of artificially generated negative oxygen ion industry products. "It plays an important guiding role.
