I, indoor air disinfection methods
1, air disinfectant disinfection:
In the absence of the presence of people in the confined space of the air disinfectant you can choose: chlorine dioxide disinfectant, hydrogen peroxide disinfectant, peroxyacetic acid disinfectant, pay attention to the disinfection must be open windows after ventilation.
If there are people in the case of air disinfection: now only slightly acidic hypochlorite disinfectant, it is recommended to choose the "CELA water", 30 years of Japan's big brand heritage, you can take people to disinfect the air without the need for special ventilation.
Safe air disinfection
Medical research has shown that the pH value of the oral environment of a healthy person is between 6.20 and 6.80, which fully reflects the long-term use of human disinfection products can not be lower than 6.20 pH value of less than 6.20 on the mucous membranes and the skin will be damaged; pH value is higher than 6.80, the bactericidal effect of a serious decline, or even ineffective. CELA non-electrolytic micro-acidic hypochlorite water pH value mimics the human oral environment, no stimulation, no side effects, to ensure the safety of long-term use.
(Hypochlorous acid is the core bactericidal substance of human immune system - one of the effective bactericidal substances generated by human blood white blood cells phagocytosis, when bacteria invade into the body or epidermis is damaged, the white blood cells will begin to play a role in resisting foreign bacteria and viruses, at this time, the white blood cells will be secreted hypochlorous acid, specializing in destroying the bacteria and viruses of the cell wall, so that the bacteria and viruses can not survive, due to the same function as the human body, which is the so-called biocompatibility, and the human body is the same. Because of the same function with human body, it is the so-called biocompatibility, not harmful. It also has the advantages of broad-spectrum sterilization, strong killing power, high security, good environmental protection, mild and convenient.
Human and animals are eukaryotic organisms, the enzyme system is mostly hidden in the cell organelles, hypochlorite can not be directly contacted, and hypochlorite in the sterilization process is through the oxidation of bacteria and other microorganisms to disintegrate, and its products are water, sodium chloride (salt), organic sugar and trace carbon dioxide and other non-toxic substances, therefore, has no residue, non-toxicity and harm characteristics.)
2, centralized air conditioning system disinfection. The use of fans, refrigeration, heating, dehumidification, purification, etc., to regulate the indoor temperature, humidity, air cleanliness, freshness and air velocity, is the air-conditioning system and the microbial concentration of indoor air will be up to within the safety limit. This method is not advocated for the time being, because of the epidemic reasons, air conditioning can lead to cross-infection.
3, ultraviolet lamp disinfection. The chances of the interior being fully irradiated by sunlight is very small, but ultraviolet light reaches a certain wavelength is by the role of sterilization and poisoning. Now there is a mobile ultraviolet lamp, indoors can be carried out, but is not very convenient, because too strong ultraviolet light is not good for the human body, but also produce radiation, ultraviolet light will also accelerate the aging of some equipment.
4, ozone generator disinfection. Ozone disinfection principle is to rely on its strong oxidation, through such oxidation to destroy the cell structure of viruses and bacteria. Ozone has a good disinfection of indoor air micro-organisms, can remove odors, the method is simple. But ozone has a corrosive effect on metals, people have a certain degree of toxicity, disinfection, good protection, it is best to leave the room, disinfection until the room can not smell the smell of ozone before you can enter the room. 5, fumigation disinfection. Fumigation method using chemical disinfectants, the use of the agent will be diluted and divided into containers, placed in a closed space in the fire fumigation. After the agent volatilized, penetrate into every corner of the room, killing bacteria. This is not a high degree of operability, easy to cause fires, less advocated.Two, indoor air disinfection precautions
1, corrosive to the items, such as ozone and other disinfectants have damage to the items, the use of the concentration should not be too high, the amount of spray should not be too large. 2, the selection of disinfectants for air disinfection, it is best to use special aerosol air sanitizers, regular sprayer fog particles, disinfectants in the air for a short period of time, it is more difficult to achieve the desired disinfection effect. 3, with disinfectants for air disinfection need to close the doors and windows, the personnel should leave the disinfection place, disinfection is completed should first open the doors and windows to ventilate, such as disinfectants completely sterilized after going in.
