Air ions vary in size, according to the size of the diameter of the particles can be divided into
1. small particle size negative ions (0. 001-0. 003um);
2. medium size negative ions (0. 003-0. 03um);
3. large size negative ions ( 0.003-0.03um);
3. Large particle size negative ions (0.03-0.1um);
The speed of their movement under the action of unit strength (V/m) electric field is called ion mobility, which is an important parameter to distinguish the size of the measured ion diameter. The smaller the diameter of air ions, the faster their migration speed.
From the above, it can be seen that the small size of the negative ion migration speed is the fastest, followed by medium size ions, large size negative ions are the slowest.
So buy negative ion products if the negative ion radiation range requirements, such as negative ion air purifier, hope that the negative ions can "run" far radiation space, you need to be able to produce the fastest migration speed of small particle size negative ions. Because the negative ions in the air survival time is very short, no more than 1 minute.
Tsinghua University, Tsinghua University, the Chinese Academy of Sciences experts Lin Jinming Professor of the book "environmental health and negative oxygen ions" is defined as follows: positive and negative air ions, according to its mobility can be divided into the size of large, medium and small ions. The ones that are beneficial to human body are small ions, also known as light ions, which have good biological activity. Only small ions or small ion groups can enter the organism.

Currently China's negative ion research in a leading position is Tsinghua University. Research on the latest breakthroughs in negative ion generation voltage the lowest in the country: the general minimum need to be about 2-3W volts, will produce ozone and nitrogen oxides and other toxic gases, and produce high-voltage static electricity, and Tsinghua University's only about 200-300 volts, will not produce ozone, nitrogen oxides, such as secondary pollution, will not contaminate the wall, will not cause damage to other electrical appliances, will not cause damage to the human body, such as affecting the function of cardiac pacemakers.

Tsinghua University research breakthroughs in negative ion migration distance of the farthest domestic: general 30cm, Tsinghua University's static emission distance is 3-4m, dynamic under the 5-6m.
Tsinghua University research breakthroughs in negative ions active concentration of the highest domestic: according to the needs of different places can be controlled to the negative ions emitted concentration. As a purification and health care needs, according to the international standard of the first-class tourist resorts is generally 1W-1.5W/cm3, as a medical sterilization effect, generally 5W/cm3 or more.
Negative ions have the following effects:
1, improve the function of natural killer NK cells that resist the activity of cancer cells, and inhibit the generation and mutation of cancer cells;
2, inhibit the generation of serum cholesterol, purify the blood, activate the macrophages, and prevent the deposition of lipids in the blood vessel wall;
3, inhibit the generation of achromatic tripletene, so that the body is less likely to cause allergic or inflammatory symptoms;
3, inhibit the generation of colorless tripletene, so that the body is not easy to cause allergies
4, inhibit the production of adrenaline, so that the expansion of peripheral blood vessels, improve blood circulation, maintain the stability of blood pressure;
5, to prevent atherosclerosis or liver dysfunction caused by the primary factor in the production of ---- lipid peroxide
6, so that the activation of various tissues and cells, and enhance immunity, for the maintenance of human health has a great role;
7, so that the activation of macrophages, preventing the deposition of lipids in the blood vessel wall;
7, make the cell metabolism, improve its natural healing power, prevent cell aging, create a young body and mind;
8, so that the body's accumulation of wastes or toxins and the cause of nerve, muscle pain and other causes of the material ---- weak acid is quickly broken down, so as to eliminate the pain and fatigue;
9, neutralization of the positive ions and make it restore, can eliminate muscle tension, Reduce mental stress, for insomnia has an extraordinary effect;
10, restore the elasticity of blood vessels, promote the smooth microcirculation of capillaries, improve the extremities of the cold syndrome;
11, so that the cell activation, improve allergies, strengthen the body's resistance, the root of the atopic dermatitis;
12, timely elimination of waste products in the skin, promote skin cell Activation, for beauty has a superb therapeutic effect;
13, so that the acidification of the organism into a weak alkaline, to promote the generation of cell tissue collagen, and decomposition, burning sugar, so for diabetes has an amazing effect.
