What are the disinfection services for indoor air disinfection?

Regular window ventilation is an effective disinfection service method to reduce indoor microbial density. Under the condition of indoor air circulating with the outside world, microorganisms can be reduced by more than 70% in the first 30 minutes, and 1 hour can be reduced by more than 90%, and bacteria can hardly be found after 2 and a half hours. This shows that ventilation is a very simple and effective method to purify indoor air, but it also has limitations. To achieve this effect, we must ensure that the weather is fine. ?

2, vinegar disinfection method: vinegar contains a variety of ingredients such as acetic acid, which has a certain bactericidal ability and can be used for indoor air disinfection services. You can use 100 ~150g vinegar per100 square meter. Add water twice, put it in a bowl and steam for 30 minutes. When boiling fumigation, it is best to close the doors and windows. Fumigation 1-2 times a day for 3 days. ?

3. Fumigation and disinfection and spraying disinfectant

Chemical disinfectants commonly used for air spray and fumigation disinfection include chlorine-containing disinfectants, peracetic acid, glutaraldehyde and chlorine dioxide. Because of the cold climate in winter and spring, families seldom open windows for ventilation. In order to eliminate indoor odor and kill pathogenic microorganisms, various air fresheners provide convenience for families. And many air fresheners are marked with sterilization effect. So many people think that air fresheners can not only improve the indoor environment, but also purify the air and sterilize it. However, according to the analysis of disinfection service experts, although the air freshener can obviously cover up the odor, it can not remove the malodorous substances in the air, and some will also produce secondary pollution.

Chlorine dioxide disinfectant is also an excellent and harmless environmental disinfectant. The concentration of spray disinfection is 200-500ppm, and the action time is about 15-30 minutes. It has a pungent smell similar to chlorine gas, which is strongly irritating and will cause eye and respiratory irritation after contact. Inhalation of high concentration can cause pulmonary edema, which can lead to death and seriously damage the respiratory tract.

4, ultraviolet germicidal lamp disinfection

The service mode of ultraviolet germicidal lamp disinfection is not only economical and efficient for household air disinfection, but also convenient for opening and controlling after installation without damaging household items. Considering the harm of ozone to human body, it is generally appropriate to use ozone-free ultraviolet germicidal lamp, and use a reflector under the lamp to make it shine on the ceiling to prevent human eyes from directly seeing the light source, because direct irradiation of both eyes will cause certain harm to eyes. The sterilization time of ultraviolet rays is short, and it takes only ten seconds to kill general pathogenic microorganisms under a certain radiation intensity, so it is not easy to achieve uniform irradiation in the whole treatment space with irradiation shadow area.

5. Vaporized hydrogen peroxide sterilizer

Fantong Biotechnology Company developed a vaporized hydrogen peroxide sterilizer to solve the disinfection problem caused by indoor air pollution. Hydrogen peroxide has bactericidal effect because of its redox effect, especially for anaerobic bacteria, which is very suitable for indoor air disinfection and surface disinfection. Vaporized hydrogen peroxide sterilizer vaporizes 35% hydrogen peroxide liquid into hydrogen peroxide vapor through high-temperature flash evaporation, which forms condensation in the space of injection space and the surface of objects, and quickly and effectively kills pathogenic microorganisms through the released strongly oxidizing free radicals. Studies have shown that vaporized hydrogen peroxide has a broad-spectrum bactericidal effect, which can kill bacteria, bacterial spores, fungi, viruses and other microorganisms. The air sterilization rate is over 99.9%, and the hydrogen peroxide in the air after disinfection is decomposed into oxygen and water vapor, which is harmless to people and the environment, pollution-free and residue-free, very environmentally friendly, and does not damage indoor articles and equipment, and does not need to be washed with clean water to remove residues.

Compared with other environmental disinfection services, vaporized hydrogen peroxide disinfection has a more thorough disinfection effect, the disinfection gas spreads evenly without dead angle, and the air and surface are fully covered for disinfection, without irritation, pollution and residue, which has good compatibility with materials and equipment and reduces the corrosion hazards of indoor items and equipment.

Experiments show that vaporized hydrogen peroxide, as a new disinfection service technology, has great advantages over traditional formaldehyde fumigation and chlorine dioxide gas disinfection in sterilization effect, personnel safety, material compatibility and environmental friendliness. At present, it is rapidly becoming the choice of biological purification methods in pharmaceutical, biotechnology and medical and health industries. In order to adapt to the disinfection service in different environments, the company has introduced portable sterilizers and intelligent disinfection robots, which are small in size, simple in operation and flexible and convenient to move, and can satisfy the disinfection of air and objects in different environments, and provide professional disinfection services for hospitals, schools, public places, hotels, biological laboratories and other places.
