What precautions should I take when using ozone sterilization? Seek more detailed explanation 20

When using ozone to disinfect the workshop, there are four things that need to be paid attention to.

The first is the ozone content in the air, which is the ozone concentration, which is usually measured in ppm or mg m3. If the concentration of ozone in the air does not reach a certain value, there is no disinfection effect at all. In general, there are two concepts of spatial ozone concentration, one is the theoretical concentration and the other is the measured concentration, and the difference between the two is very different.

Therefore, when designing an ozone disinfection program, it is important to find out what concentration value is actually needed.

The second is the uniformity of ozone distribution in space. This is an important issue that many ozone generators and users ignore. In a space, if the ozone distribution is more here and less there, then the ozone less area will definitely not achieve the planned disinfection effect.

From the definition of sterilization and disinfection, if the disinfection effect of one area in a space is not up to standard, it is actually equivalent to the disinfection effect of the entire area is not up to standard.

The third is the duration of action. If time permits, it is best to continue treatment for 30 minutes or more after reaching the specified ozone concentration.

The fourth is to choose an ozone generator with reliable quality. At present, the domestic ozone market is relatively chaotic, there is no shortage of fake and shoddy products, users had better choose those who have a certain brand awareness, have corresponding user cases, and are currently running stably manufacturers, do not be deceived by low prices and rhetoric.

Hello, friend who asked the question:

1: Ozone disinfection is safe and convenient to use, and pharmaceuticals can use ozone disinfection normally if they have the following conditions

1. There should be no flammable and explosive gas and conductive dust in the room. It is forbidden to install in dangerous areas where ammonia is easy to leak or there is a danger of occurring.

2. There is a 220V 50Hz AC power supply indoors. Some ozone equipment also requires 380V 50Hz AC power.

3. Ambient temperature requirements: -10 -33

4. Environmental humidity requirements: 55%.

5. The ground on which the machine is placed is required to be flat, and attention should be paid to placing the equipment smoothly on the ground or on the bracket.

6. Keep the working environment of the equipment ventilated and dry during the installation of the equipment, and the space must be equipped with an exhaust fan or air conditioner.

2. Do not use this product near high-precision electronic equipment when using ozone, as radio wave interference may cause misoperation and other problems of high-precision electronic equipment. Special care should be taken in the vicinity of hearing aids, pacemakers and other medical electronic devices, fire detectors, and other precision automatic control devices.

Do not disassemble or modify this product, as this will cause damage, leakage, and circuit failure of this product.

Avoid excessive moisture, water or other liquids entering this product may cause leakage and malfunction of this product.

Avoid wiping the device with volatile solutions or organic solvents, which may damage the surface of the device.

Qualified special grounding wire, safe and reliable grounding, the capacity of the line used is in line with the requirements to ensure the elimination of fire hazards. Equipment installers must be trained before they can be turned on for maintenance.

When using ozone, it is strictly forbidden for staff to work in a high-concentration ozone space environment, and staff should have protective measures when working in a space environment with ozone concentrations exceeding the relevant standards.

Remember that equipment maintenance or repair must be carried out in a state of power failure and exhaustion of air pressure to ensure the safety of personnel.

The answer from the ozone generator manufacturer "Guangzhou Olison Ozone Equipment Technology ****".

1.The concentration and output of the ozone machine are selected according to the volume of the space and the level of sterilization.

2.Seal the sterilization room during sterilization.

3.Personnel avoid the sterilization site during sterilization; Half an hour after the sterilization shutdown, you can enter the sterilization room, and I personally recommend the Huanwei ozone sterilizer, with a fully automatic control switch.

1. People must leave the scene during ozone disinfection.

Ozone has a significant killing effect on microorganisms in the air, including coronaviruses, but ozone needs to be concentrated at a concentration of 20mg m3 to achieve the purity of disinfection. However, the safe ozone concentration for humans is:

Therefore, when it is necessary to use ozone to sterilize and disinfect the home, it must be carried out in an unmanned state. If you need to disinfect when there is an occupancy, you must meet the industrial hygiene standards for ozone, and you must purchase a pumped ozone test to measure ozone concentrations.

2. It cannot be used beyond the volume range.

Different models of machines have their maximum disinfection range, and the use of ozone disinfection machine should not exceed its specified disinfection volume range, otherwise the disinfection effect will be affected.

3. The higher the humidity, the better the disinfection effect.

The higher the humidity of ozone, the better the sterilization effect, and the general requirement is more than 60%. This is due to the fact that the cell membrane swells and thins under high humidity, and its tissues are easily destroyed by ozone.

4. Do not enter immediately after the disinfection.

Use ozone sterilization and disinfection, be sure to avoid being inhaled as much as possible. After ozone disinfection of orange clusters, it must be shut down for 30 to 60 minutes or open the window for ventilation for 20 minutes, and the room can only be entered when the ozone smell is not smelled.

5. Ozone has a corrosive effect on metals and rubber.

Ozone corrodes ordinary rubber products, metal products, etc., and non-corrosion-resistant items and instruments and equipment must be removed from the disinfection environment of the machine.

After ultraviolet irradiation, a part of the oxygen in the air is decomposed into single-molecule oxygen, so that the single-molecule stove oxygen is combined with the surrounding oxygen to form ozone. Since this binding is unstable, the ozone is also unstable and is quickly emitted.

Ozone has strong oxidizing properties, is a stronger oxidant than oxygen, can undergo oxidation reactions at lower temperatures, such as oxidizing silver to silver peroxide, leading sulfide to lead sulfate, and potassium iodide reaction to form iodine. Turpentine, coal gas, etc. can spontaneously ignite in ozone. Ozone is a powerful bleach agent in the presence of water.

Unsaturated organic compounds are also prone to the formation of ozonions at low temperatures.
