Scope

Scope: This standard specifies the technical requirements, including technical indicators and testing methods, for the generation of negative oxygen ions by artificially produced negative oxygen ion products. This standard applies to the industry of artificially produced negative oxygen ion products. Main technical content: Negative oxygen ions, also known as air negative ions, refer to oxygen ions that gain one or more electrons and carry a negative charge. They are formed when oxygen molecules in the air combine with free electrons. Since the main components of air are nitrogen (78.09% by volume) and oxygen (20.95% by volume), nitrogen is very stable and has a much lower electron affinity than oxygen. Therefore, the vast majority of free electrons combine with oxygen molecules, and the vast majority of negative ions generated in the air are negative oxygen ions. Negative oxygen ions have excellent functions of purifying and removing dust, decomposing formaldehyde, and reducing the harm of second-hand smoke. At the same time, negative oxygen ions are very beneficial to human health and are known in the medical community as "vitamin O", "air vitamin", and "longevity factor". The mobility of ions in an electric field of unit intensity (V/m) is called ion mobility, which is an important parameter for determining the size of the tested ions. Ion mobility is an important parameter for expressing the size of the tested ions. The speed of ion movement is inversely proportional to the diameter of the ion, while ion mobility is directly proportional to the speed of ion movement, so ion mobility is inversely proportional to the diameter of the ion. The principle of negative oxygen ion generation: Under normal conditions, gas molecules and atoms have equal positive and negative charges. However, under the action of energy generated by cosmic rays, ultraviolet rays, electromagnetic waves, radiation from rocks and soils, polar materials, waves, waterfalls, and various m
