Small particle size of the cognition of the anion
Air anions, also known as negative oxygen ions, refer to the acquisition of one or more electrons with negatively charged oxygen ions. It is formed by the combination of free electrons with oxygen molecules in the air. The discharge(lightning) phenomenon in nature, the photoelectric effect, fountains, waterfalls, etc. can Ionize the surrounding air to form negative oxygen ions. The negative ion has an excellent effect of purifying and removing dust, reducing the hazards of second-hand smoke, improving the prevention of respiratory tract, improving sleep, suppressing free radicals in the body, and reducing blood viscosity. In the medical community, it enjoys the reputation of "Vita Oxygen", "Air Vitamin", "Longevity Factor" and "Air Vitamin".However, air anion rarely exists in the environment in a single way. Because it has its own characteristics of charge and motion, the anion in the environment is mostly present in the environment in several or more groups. Therefore, The more negative ions a negative ion group contains, the larger its volume will be, and it will also affect its mobility(ie, activity). Therefore, we divide the air negative ions into three types of ions: large, medium, and small(actually three kinds of ion groups) according to their migration distance and particle size. The main benefits to our human health are small particle size negative ions.
Small particle negative Ion is also called light ion or small Ion. It is an air negative ion that is equivalent to nature, and it is also known as an ecological grade negative ion. It has the characteristics of long migration distance and high activity. Medical research shows that it is small particle negative ion that has a medical care effect on the human body. Because only small particle size negative ions can easily pass through the body's blood-brain barrier and exert its biological effects. The reason why the air anion in nature creates many longevity villages is because the small particle size anion ratio is high, and the small particle size anion has a negative ion bath environment over the longevity area because of its high activity and long migration distance.
Small particle size negative ions are mainly found in natural environments with relatively few pollutants and good air mobility. The reason why the environment in places such as forests and parks can effectively form a high-concentration small particle size negative ion environment. The main reasons are: First, there are many sources of negative ions and wide distribution(plants, water sources, rocks, etc. are all sources of negative ions), and second, there are fewer pollutants in the environment(green plants can effectively adsorb and decompose pollutants). The third is a good air circulation environment(unlike the city, there are too many tall buildings that interfere with air circulation). All factors are combined to make the negative ions in space less likely to form large particle size negative ions, and a good environment is also better than the negative ions have better mobility and activity.
So how should we effectively identify small particle size negative ions?
Referring to the definition of "Environmental Health and Negative Oxygen Ions" written by Professor Linjinming of Tsinghua University and expert of the Chinese Academy of Sciences, the ion mobility is greater than 0.4 cm2 /(V 's) for small ions and less than 0.04 cm2 /(V' s) for large ions, Between the two are medium ions. Charged atomic groups or molecular groups that are close to the size of molecules belong to small air ions. The ion mobility of the middle finger is defined as the speed at which the negative ion moves under the action of the unit strength(V/m) electric field. Ion mobility is an important parameter for distinguishing the diameter of the measured Ion. The smaller the diameter of air ions, the faster their migration speed, and the greater the distance and range of their movement, the longer the existence time. Ion mobility is an important parameter for expressing the size of the ions to be measured. The ion motion speed is inversely proportional to the ion diameter, and the ion mobility is proportional to the ion motion speed, so the ion mobility is inversely proportional to the ion diameter. For our living environment, our outer layer of the earth has a fixed electrostatic atmosphere ionosphere(our communication only allows long-distance transmission, in fact thanks to the reflection of the signal layer to the signal layer). The ionosphere is positive, On the contrary, our earth is negatively polar before it maintains a state of dynamic equilibrium. Therefore, in this natural electric field environment, positive ions and negative ions will be in a free motion state(Brownian motion), and small particle negative ions have better mobility because they have better mobility in this electrostatic field, so they have better activity., farther migration distance, Therefore, negative ions are formed in the life cycle from formation to disappearance(negative ions are formed by oxygen molecules that obtain free electrons, so under the influence of other environmental factors, the obtained free electrons will lose their oxygen molecules at any time. That is to say, the negative ion has a survival time. First, it can move freely at a longer distance. Secondly, due to the longer survival time, the small particle size negative ion can effectively form a healthy and superior overall environmental space.
