What is negative ion?
So-called negative
ion is electronegative corpuscule. For example, corpuscule with
positive electricity in the air is called positive ion, while corpuscule
with negative electricity in the air is called negative ion.
But corpuscule is atom with electron in pelagic air. In the air, tiny water
molecules and oxygen molecules with negative electricity can combine to
generate negative ions that can promote the metabolism
when coming into human blood through lung. That’s why people will feel better
when they are in forest or close to waterfall.
What
factors does the concentration of negative ions in the air have
relation with?
In the natural air, the concentration of negative
ions depends on the climate, geographical conditions and atmosphere
pollutions, etc. According to tests, the concentration of negative ions
reaches its highest data from June to September, and reaches its lowest
data from Jan. to March. In the rest months, it varies between the two data
above. Generally, on the surface of the earth, the concentration of negative
ions is about several thousand pcs per one cubic centimeter. It is only
10~30pcs/cm3 in metropolitan theater, 40~50pcs/ cm3
in metropolitan room, 100~200pcs/cm3 in the green belt, 400~600pcs/cm3
in the park, 700~1000/ cm3 in the suburb and 20000pcs/cm3
or more in the seashore, valley, waterfall area.
Negative ion in the air is absolutely necessary
to human being just like sunshine. The life of negative ion
is very short, it’s about a few minutes in clean air and
only a few seconds in dirty environment or even shorter. In
the open fields, seashores, country, water and spring areas
its life can reach to more than 20 minutes, because in these
areas the air pressure is smaller and the dust is fewer, so
more negative ions can be generated from the air. The World
Health Organization advises that the concentration of negative
ion in fresh air shouldn’t be below 1000~1500pcs/cm3.
However, due to too many cement road surface, large vehicle
flow rate, industrial pollutions and high population density,
etc., the concentration of positive ions such as suspending
granules, germina and dust, etc., will increase, and the concentration
of negative ions will obviously decrease. That can lower the
quality of air and affect health level of human body.
What
symptoms will the decrease of the concentration of negative
ions in rooms cause?
1. When you get up in the morning,
if you feel hard to breathe, nausea, light headedness, or
your blood pressure is higher than usual
2.There is some smell excitative to your nose
or eyes, and this smell is hard to dispel for a long time.
3.Insomnia, dysfunction of autonomic nerve,
functional nerve disease, feeling dizzy or headachy or fretful.
4.Inappetence, functions of immunity lower,
body resistibility lowers, easy to feel tired, always catch
cold, the skin is sensitive.
5.You don’t smoke, but you always feel
uncomfortable with you throat, always cough, and can’t
breathe smoothly.
6.Plants at home are difficult to live, most
of your family members have the same disease that will disappear
or affect you less when you leave away from home.
Learning from the nature, people start to generate negative
ions through artificial ways. These man-made negative ions are put into
around the air around to purify the air and improve living environment.
The equipment with man-made way to generate negative ions is called air
negative ion generator or negative
ion generator.
Working
elements of negative ion generator
The generation of negative ions is that negative
ion generator makes low pressure through boosted circuit to direct
current negative high pressure, and utilizes tip direct current high pressure
to produce high corona, rapidly release mass electrons, which will be immediately
caught by oxygen molecule (O2) in the air, and forms high strength negative
ion group, and combines with bug cells in the air to transfer energy from
inside the cell, modify structure, cause its death, and centralize breathable
particles in the air, such as smog, dust and pollen, etc and naturally subside,
so as to reach the aim of purifying air.
What performance
index does negative ion generator have?
Main performance index to measure good or bad of negative
ion generator:
(1) Concentration of negative
ions: containing negative ions volume for per ml air, namely
pcs/cm3. Requirement of index:
the concentration of negative ions in the place where is 20cm
away from the uptake should be bigger than 105 pcs/cm3.
(2) Ozone content: It is benefit for human body health
to maintain minim ozone, if it is excessive, it will be harmful. According
to national standard the strength of ozone, in the place where is 5cm
away from the window plane, it is not bigger than 60ppb (1ppm=106,
1ppb=109). The content of ozone for better negative
ion generator should be smaller than 0. 05ppm.
(3) Power supply: Using directly alternating
current for the city electricity or direct current 3V~24V.
(4) Consumed power: The products have big
and small difference and consumed power is generally 0.5W~1W.
(5) Application area: Generally 10 ---20m2.
(6) Working way: The negative ion generators
can work in succession. Longer working time will generate negative ions
continuously.
How to
choose negative ion generator
(1) Adopt a semiconductor radio,
magnify its volume, and close to the negative ion generator,
products with good performance will not bring disturb to the
radio outside 30cm, that proves the negative ion generator
won’t happen high-frequency electric magnetic field and
ultrasonic wave.
(2) Good negative ion generator has very
strong smoke elimination and dust removal function. Close to the export
of negative ion generator with lighting cigarette, the
cigarette rising will pour to the finger, not diffusing to the air, one
minute later, cigarette tail and finger are smoked yellow, that proves
performance of this negative ion generator is good.
(3) Cover one new plastic food bag on hand,
when hand closes to the export of the negative ion generator,
the plastic film will be stuck on hand closely, even though
turn off the generator, the function of adsorbing hands can
also keep for some time. The products with bad performance
do not have this kind of phenomenon.
Method
to test the existence of negative ion
1. Put negative ion generator products just
frontage of air ion concentration tester and can test its concentration.
2. Put hand 5cm in front of the carbon fibre
output negative high-voltage line, you will feel a stream
of cool wind.
3. Put negative ion generator in the
environment with peculiar smell, you will find some time later the peculiar
smell is eliminated obviously.
4. Fetch a transparent container with lid,
put negative ion generator into it, turn off after being electrified
for 5 seconds, and then input smog among it, then open the
switch of the power, you will find the smog in the transparent
container will be purified in speediness.
Precautions
for using negative ion generator
The human body should try one's best to avoid
closing to the high-pressure output end before grounding (carbon
fibre head), for fear generating the pole board effect. This
kind of phenomenon is normal and has no harm to human body.
Functions
of negative ion
(1)Eliminate smoke and de-dust.
The negative ion can neutralize burnt smoke, "second hand
smoke ", lampblack and floating dust belonging to the positive
ion in the air rapidly.
(2)Improve the air structure: People need
13 hundred million negative ions per day, but our room, office,
place of entertainment, etc. environment can only offer about
2~20 hundred million negative ions. That often causes breathing
diseases, such as the pneumonia, tracheitis, etc.
(3)Improve the lung function: After inbreathing
negative ions for 30 minutes, the lung can increase 20% oxygen
absorption, and get rid of 14.5% more the carbon dioxide.
(4)Improve the myocardium function: Obviously
function of lowering pressure can make people inspired and
increase working efficiency.
(5)Accelerate metabolism: Can accelerate metabolism
and improve sleep.
(6)Strengthen human body's resistance against
diseases: Negative ion can improve the response of the human
body and strengthen human body's resistance against diseases.
(7)Air negative ion can relax and cure irritability
pollenosis, bronchus, the upper respiratory tract mucous membrane
inflammation, etc.
(8)Have auxiliary and therapy function to
respiratory system disease/menopause symptom, and no side
effect.
(9)Neutralize high-pressure static of TVs
and computer screen to prevent short sight effectively. At
the same time reduce the harm of dusts to TVs and computers.
Application of negative ion generator
Widely used for hair dryer, air conditioner,
electric fan, sports apparatus, computer, power-saving
lamp, ceiling lamp, vending machine, air
clean machine, view basin, artificial flower, kitchen
ventilator, hairdressing, etc. household appliances field.
