Length What are negative air ions?
Air is a mixture of gases, and its main components are nitrogen, oxygen, carbon dioxide and water vapor. Usually, all kinds of gas molecules in the air are stable and neutral, that is, uncharged. However, due to natural cosmic rays, ultraviolet rays, thunder and lightning, wind and waves, plants and so on. It will cause the surrounding air to ionize and produce negative ions, also called air negative ions. Air negative ions are essentially negatively charged air particles. Generally speaking, air negative ions refer to negative oxygen ions, which are formed by the combination of oxygen molecules in the air and free electrons. The discharge (lightning) phenomenon, photoelectric effect, combustion process, fountains, waves and waterfalls in nature can ionize the surrounding air and form negative ions.
2. What factors are related to the number of negative ions in the air?
In natural air, the number of negative ions is related to climate, geographical conditions and air pollution. According to the determination, the concentration of negative ions is the highest in June and September, the lowest in1-March, and the rest months are between the two. On the surface of the earth, the concentration of negative ions is generally several thousand per cubic centimeter. There are only 10-30 cinemas in big cities, 40-50 rooms in big cities, 100-200 green belts in streets, 400-600 cinemas in parks and 700-/kloc-0 /cm3 in suburbs.
3. What effect does negative air ions have on human body?
Air negative ions, like vitamins in food, have a very important influence on human life activities, so they are also called air vitamins. It can promote the growth and development of human body and prevent many diseases, mainly in:
(1) For respiratory system: improve lung function. After inhaling negative ions for 30 minutes, the absorption of oxygen in the lungs increased by 20%, and the elimination of carbon dioxide increased by about 14.5%.
(2) It has obvious hypotensive effect on cardiovascular system, which can improve myocardial function, increase myocardial nutrition, dilate peripheral capillaries and increase skin temperature.
(3) For the nervous system: it can refresh the mind, improve sleep, and has obvious sedative and analgesic effects.
(4) Metabolism: it can activate various enzymes in the body, reduce blood sugar and cholesterol after absorbing negative ions, increase blood calcium, urine volume, nitrogen and creatinine in urine, accelerate bone growth, and prevent scurvy, rickets and vitamin deficiency.
(5) For blood: it can increase white blood cells, red blood cells, hemoglobin, reticulocytes and platelets, slow down erythrocyte sedimentation rate, increase globulin, raise PH value and shorten coagulation time.
(6) Immunity: It can improve the body's reactivity, activate the function of reticuloendothelial system and increase the body's disease resistance.
4. What are the applications of negative air ions in medical care?
Inhalation of negative air ions is very common in the treatment of respiratory diseases. Foreign 1300 cases of bronchial asthma, after the treatment of responsible ion, the attack was controlled by 55%, the condition was relieved by 35%, and the effective rate was 10%.
Negative ions also have a good therapeutic effect on some respiratory infectious diseases. For example, pertussis in children, 25% of patients can be cured after 3-5 treatments, and some patients can be cured after 10- 15 treatments.
For chronic rhinitis and chronic pharyngolaryngitis, inhalation for 20-30 times each time has a good curative effect.
Other diseases treated by air negative ions include neurosis, insomnia, migraine, hypertension, dysmenorrhea, menstrual dermatitis, trauma and burns.
Negative ions are nontoxic and have no side effects. Generally speaking, it is ideal to use air negative ions as adjuvant therapy.
5. What are the main performance indexes of the negative ion generator?
The main indicators to measure the performance of air negative ion generator are:
(1) Negative ion concentration: refers to the number of negative ions contained in each milliliter of air, that is, one cubic centimeter. Index requirements: the concentration of negative ions at 30 cm away from the air outlet cavity should be greater than 10-5 cubic centimeters.
(2) Ozone content: keeping a small amount of ozone indoors is beneficial to people's health, while excessive ozone is harmful. According to the national standard, the ozone concentration should not be greater than 60ppb( 1ppm= 10-6, 1ppb=l0-9) at 5 cm in front of the window plane. The ozone content of a good negative ion generator should be less than 0.0 15ppm.
(3) Noise standard: refers to the negative ion generator with fan. The noise is generally between 45 and 60 decibels.
(4) Power supply: directly use commercial AC power supply or 3V~24V DC power supply.
(5) Power consumption: the products are large and small, with or without fans, and the power consumption is generally between 0.5 and 5W. ..
(6) Adaptive area: general10-60m2.
(7) Working mode: All negative ion generators can work continuously.
(8) Whether electrostatic slapping will cause injury and high radiation.
6. What are the functions of negative ion generator in health care?
(1) The negative ion generator can eliminate or alleviate people's bad emotions and improve work efficiency in clean rooms, precision instrument rooms, laboratories and other environments without air circulation.
(2) For people with high labor intensity, such as miners and athletes, the negative ion generator can make people less tired.
(3) error-prone personnel, such as typists, telephone operators, accountants, etc. You can use a negative ion generator to make your mind clear and your spirit happy.
(4) When watching TV programs, because the fluorescent screen emits a large number of positive ions, it is necessary to absorb the surrounding negative ions. Therefore, the negative ion content in the room is greatly reduced, and people will feel uncomfortable when watching TV for a long time. The negative ion generator can supplement the negative ions in the room.
7. How will the negative ion generator technology develop?
At present, the world's leading high-purity air negative ion technology is an "ion converter" technology invented by Japanese scientist Moriguchi, MD, who is known as the "first person of negative ions". It is a patented technology that uses the natural resources of the earth to generate natural air negative ions. It is understood that since 2006, the products and technologies related to this important invention have been introduced to China by the internationally renowned brand Celumet (Baidu can find the website of Celumet brand, and the introduction of negative ions is more comprehensive). The air negative ions produced by it are no different from those produced in nature, which is very suitable for regulating human body functions and plays an important role in improving physical fitness and maintaining health. At present, Sailumei brand has successively launched negative ion therapeutic apparatus, indoor negative ion vitamin convalescent machine, central air conditioning type and portable series of negative ion products.
