With the development of human science and technology, based on the current knowledge of human beings, it is concluded that the main influencing factors of human health are as follows: the first genetics, the second mentality, the third diet, the fourth environment, the fifth exercise, Among them, heredity is congenital, two and five can be completely adjusted artificially, and the impact of diet and environment on human health is largely affected by the objective environment.
When it comes to the environment, we have to mention microorganisms, which mainly exist in the air, water and soil. The microorganisms that cause diseases in humans and animals are called pathogenic microorganisms, and there are the following 8 categories
There are few opportunities for humans to directly contact the soil. The impact of human health in the objective environment is mainly air and water. At present, the technology of human water treatment is quite mature. We can say that the biggest threat to human health is the air, because there are a large number of microorganisms in it. There are, especially pathogenic microorganisms. Therefore, we have strict grade requirements for air sterilization in the production of medicine and food, such as ISO14644-1. There are three sterilization methods, namely physical sterilization, chemical sterilization and mixed sterilization.
- dry heat sterilization,
- moist heat sterilization,
- high pressure steam sterilization
- ethylene oxide,
- glutaraldehyde and formaldehyde,
- hydrogen peroxide
The body’s own immune system is like the body’s guardian. When it encounters bacteria and viruses in the external environment, it will automatically kill them. When the number of bacteria and viruses is too large for the body’s immune system to compete, our body will Sick, so we can say that in order to be healthy we have to do everything possible to eliminate or reduce these disease-causing bacteria and viruses. In the classic sterilization method, ozone is called a green fungicide. Why? Ozone is a very strong gas oxidant and bactericidal and disinfectant, which can effectively make microbial cells produce a variety of oxidation reactions from the outside and inside, directly destroy their ribonucleic acid (RNA) or deoxyribonucleic acid (DNA) substances, and kill them completely. Kill bacteria and mold microorganisms, and after sterilization, ozone will turn into oxygen, and oxygen is beneficial to the human body.
CE Environment Technology Co., Ltd. – www.ceenvironment.com The industrial ozone sterilization and disinfection has requireemnt for CT value, C called CO3 is the ozone concentration, and T is the maintenance time after the ozone concentration reaches the standard. For example, ozone drinking water disinfection requires CT=1.6, C=0.4ppm, T=4 minutes, while in daily life The requirements for the environment are far from necessary to meet the industrial sterilization standards. The main purpose of using ozone in our daily life
- Purify the air
- Food preservation
- Removal of odor, smell, smoke
How does a high voltage discharge ozone generator produce ozone?
There are two core electronic components inside the ozone generator, namely the high-voltage package and the discharge electrode. First, the high-voltage package will increase the voltage of the power supply. There is static electricity, and electricity will form an electric field, and the electric field will have an electric field strength, which is expressed by the formula as E=K*Q/R^2(k=9.0×10^9N.m^2/C^2) or E=U/ D (uniform electric field), we know from the formula that the closer the distance to the electrode, the greater the electric field intensity. As the voltage increases, when the electric field formed by the electric charge on the electrode reaches the ionized air, it means that the electric field strength forms When the energy is sufficient to decompose oxygen molecules into oxygen atoms, the air is ionized, that is to say, the air conductor conductor can conduct electricity, and these decomposed oxygen atoms will quickly combine with the oxygen molecules in the air to form ozone; at the same time, by the formula we It is known that the air in the place closer to the electrode is first ionized. Why do we talk about this distance? The greater the amount of electricity, the larger the range of air ionization. At present, the air ionization distance of small ozone generators in the industry is usually controlled by voltage. About 2 mm away from the electrodes, so that no electric shock will occur. (Industrial ozone generators have high demand for ozone and high voltage requirements, so an insulating layer, glass or quartz glass should be added to the electrodes)
In the refrigerator, in addition to killing or inhibiting the growth of mold and preventing rot, ozone also has the effect of preventing aging and other preservation. The mechanism is that ozone can oxidize and decompose the ripening agent-ethylene gas C2H4 breathed out by fruits and vegetables. Ethylene intermediate product It also has an inhibitory effect on microorganisms such as mold. Ozone can play a role in sterilization and mildew prevention and rapid decomposition of ethylene to slow down metabolism; while in kitchens and bathrooms, ozone plays a role in removing fishy odors, mainly by oxidizing them. Ammonia compounds.
The mini ozone generator CE-CY-30G has DC5V, four battery power supply or car USB power supply, and its working time has two settings.
Method 1: Work for 10 minutes, stop for 20 minutes, and cycle within 12 hours
Method 2: Automatically shut down after 4 hours of continuous work
Is it safe to use the mini ozone generator CE-CY-30G in these places? First of all, let’s look at the limits of the safe concentration of ozone in major countries in the world, that is, the concentration and time of ozone that the human body can normally and continuously contact.
International Ozone Association: 0.1ppm, contact time for 10 hours
United States: 0.1ppm, contact time 8 hours
Germany, France, Japan: 0.1ppm, contact time for 8 hours
China: 0.15ppm, contact time for 10 hours
We know that in the air, the concentration of ozone is 1ppm=2.144mg/m3, the decomposition half-life in the air at normal temperature and normal pressure is about 20~30 minutes, and the hourly ozone output of CE-CY-30G mini ozone generator is 3 mg , one hour of work for 20 minutes, the ozone output is 1 mg, 50% of the decay is oxygen in one hour, and the remaining 0.5 mg. The volume of toilets, cars, wardrobes is usually three cubic meters, or even larger, and it is ventilated, so it is converted by 3 cubic meters , so for 0.5mg in a 3 cubic meter, CO3=0.5mg/3m3/2.144mg/m3=0.08ppm, which is lower than the safe concentration, and that it has not considered ventilation, therefore, the mini ozone generator is beneficial and harmless to the human body.
What is the difference between ozone type air purifiers and HEPA filtered air?
- The principle of the ozone type air purifier is to ionize the oxygen in the air to generate ozone, and then the ozone will sterilize 360 degree without dead ends when the air flows, and ozone can kill all bacteria and viruses.
2. HEPA is a folding mechanical air filter, it is a physical filter function to remove dust, pollen, mold, bacteria and any particles in the air with a size of 0.3 microns (µm), but it has no active sterilization function , when there is no air passing through, there is no sterilization effect.
