I want a wellness room with more negative oxygen ions. How are negative oxygen ions mainly produced?

How to generate negative oxygen ions:

The concentration of negative ions in the air has a great relationship with the ionized and excited state of air molecules. The so-called ionization is the process of forming positively or negatively charged particles in the atmosphere; the so-called excitation is the process in which atoms absorb a certain amount of energy from the outside world, causing the valence electrons of the atoms to jump to a higher energy level. The electrons gain a certain amount of kinetic energy from the outside world and interact with the air. Atomic collision is an important condition for the excitation and ionization of air atoms. There are two types of negative oxygen ions in the air, natural and artificial.

1. Ways to generate negative oxygen ions under natural conditions:

(1) Negative ions are generated in natural phenomena

The atmosphere is affected by ultraviolet rays, cosmic rays, and radiation Under the influence of factors such as substances, thunderstorms, storms, soil and air radiation, ionization occurs and electrons are released. The electrons are absorbed by the earth and then released, and soon combine with neutral molecules in the air to become negative ions, or anions. .

Natural negative ions (that is, negative ions that play a good and reducing role in the body) have great antioxidant effects and reducing power. The reason why the air after rain is particularly fresh is because lightning ionizes the air, thereby producing a large amount of ecological-grade negative oxygen ions.

(2) Negative ions are generated in high-speed flow

In natural processes such as waterfall impact, thin waves, and heavy rain, water flows at high speed under the action of gravity, causing water droplets to break , water molecules break apart and lose electrons to become positive ions. Oxygen molecules in the surrounding air capture these electrons and become small-sized negative ions.

This is also the reason why the concentration of negative oxygen ions around waterfalls, seashores, fountains, etc. is particularly high.

(3) Negative ions are generated during plant growth

The "tip discharge" effect of coniferous plants will ionize the surrounding air and produce a large amount of negative oxygen ions.

Forest trees can also ionize the air and produce negative ions.

In addition, terpenes and aromatic substances secreted by some trees, flowers and plants can ionize the air to produce abundant negative oxygen ions.

(4) Negative ions are generated in crustal rocks

Some crustal rocks can release a certain amount of negative ions. For example, natural fiber gypsum mines with well-developed crystals can be hand-made into pure natural air purifiers - crystal gypsum lamps.

2. Artificial methods to generate negative oxygen ions

(1) Ultraviolet irradiation method

Ultraviolet light generated from quartz mercury lamps can ionize the air, and its electrons pass through The photoelectric effect occurs on nearby metal or dust particles, and negative ions are generated by adhesion. This ultraviolet light also produces ozone.

(2) Thermionic emission method

When certain materials such as metals are heated to a certain temperature, they will emit electrons. The number of electrons emitted is determined by the thermionic emission characteristics and temperature. . These ejected electrons create ions by attaching to oxygen and small dust particles. Most of the negative ions produced by this method are large charged ions, and only a small part are small ions that can activate human physiological energy.

(3) Radioactive material irradiation method

Radioactive materials can be used to generate negative ions in the air. Among them, radioactive isotopes that emit alpha particles are the most effective ion generators. For example, an alpha particle of polonium 210 can produce about 150,000 ion pairs, which can exclude electrons from nitrogen and oxygen. Among the ions obtained, negative oxygen ions dominate.

(4) Corona discharge method

It refers to adding a high potential difference between two electrodes. One of the electrodes is a sharp needle with a small diameter, surrounding the needle. The high electric field of the needle-shaped electrode will generate a large number of positive and negative ions. If the pointed needle-shaped electrode is a negative electrode, the positive ions will be quickly absorbed, and the negative ions will be repelled to the opposite electrode, producing air negative ions of corona discharge. Most of the popular negative ion generators on the market currently use the corona method to generate negative ions. The electrodes are bipolar, generally the negative electrode is in the shape of a needle, and the positive electrode is in the shape of a ring. This type of technology is still based on early research, with little innovation, generally low negative ion concentration, poor expansion performance, and high ozone concentration.

(5) Water ionization method

Using the jet effect of high-pressure water, a fine stream of water is sprayed from the nozzle into the air. When it splits, it forms air negative ions.

Our country has successfully developed a powerful negative ion fountain, which uses a high-pressure water jet ejection device to emit more than 100 trillion negative ions from a nozzle with a diameter of 2mm, forming an electronegative climate environment above tens of thousands of square meters of ground. This kind of equipment is usually installed on fountains in city squares, parks, hotels, sanatoriums and pavilions, as well as on modern musical fountain pools, forming a negative ion treatment area and is not suitable for home use.
