What are the things that need to be thought about in the whole process of ultraviolet disinfection i

Notes:1The ultraviolet light of the ultraviolet germicidal lamp will have a certain impact on the human body, and cannot be directly irradiated to the human body. Be careful to let young children out when disinfecting.

2.The space that needs to be disinfected needs to be exposed to ultraviolet rays for a sufficient time, and to ensure that the ultraviolet rays are of sufficient intensity, irradiation time: 30 minutes to 60 minutes. Ultraviolet germicidal lamps per cubic meter required.

Both: 20 square meters of space needs 30W ultraviolet germicidal lamp, and so on.

3.The environment also has an impact on the germicidal effect of ultraviolet germicidal lamps, and the output intensity of ultraviolet rays is strongest between 27 and 40 degrees Celsius. High humidity or dust will reduce the ultraviolet germicidal lamp.

Bactericidal ability. Solid sterilization environments need to be kept clean and dry. Ultraviolet germicidal lamps.

Wipe with alcohol every 2 weeks.

4.It is not enough to rely on the intensity of germicidal ultraviolet lamps based on the wrong blue light or the presence or absence of ozone. Regular testing with a UV intensity meter is required.

When the intensity is less than 50 w cm2, the ultraviolet germicidal lamp needs to be replaced, the ultraviolet germicidal lamp has a slow leakage phenomenon, and the lamp needs to be replaced immediately after 8000 hours of ultraviolet germicidal lamp use, generally once every 1 year.

5.When using ultraviolet germicidal lamps for sterilization, it is best to close the doors and windows, close the curtains, and turn on the quilts and books. In order to achieve a better sterilization effect.

The use of ultraviolet germicidal lamps in kindergartens can better protect the healthy growth of babies, and kindergartens need to pay special attention to the above points in the use of ultraviolet germicidal lamps.

It is best to disinfect with ultraviolet light at night.

The hanging height of the UV lamp. It should be hung vertically, meters above the ground.

2.The range of ultraviolet lamps is used, germicidal ultraviolet lamps.

The line emitted from the inner surface is blind residual C wave crack dust, and its wavelength range is 200-270nm, and the center wavelength of sterilization is. at ultraviolet intensity.

and when the irradiation time is sufficient, it can kill all microorganisms.

3.The cumulative time of each ultraviolet lamp is 1000 hours of grinding source rolling, and if it exceeds 1000 hours, it should be replaced with a new one in time. If it is newly replaced, the replacement time should be indicated, and the use time should be accumulated again.

4. During the use of ultraviolet lamp, the surface of the ultraviolet lamp should be kept clean, generally once every two weeks with alcohol cotton ballsasafras, and when it is found that there is a gray layer and oil stain on the surface of the lamp, it should be tested at any time.

5. The disinfection time of ultraviolet lamp should be 30 to 60 minutes each time.

Ultraviolet disinfection lamps radiate ultraviolet light with a wavelength of outward. This band of ultraviolet light has the strongest sterilization ability and can be used for disinfection and sterilization of water, air, clothing, etc. The specifications of ultraviolet disinfection lamps commonly used in pig farms are 15W, 20W, 30W and 40W, and the voltage is 220V, which is mainly used for disinfection and sterilization of personnel, and is generally installed in disinfection locker rooms, veterinary rooms and laboratories.

Generally, it is disinfected once a day, after the children are all out of school, 30 minutes to an hour, and it is fine.

Ultraviolet disinfection lamps are used to kill bacterial propagules, spores, mycobacteria, coronaviruses, fungi, rickettsial and chlamydia, etc., and all surfaces, water and air contaminated by the above viruses can be disinfected with ultraviolet light. Ultraviolet disinfection lamps are mainly divided into: high pressure, medium pressure and low pressure.

Disinfection application, mainly low pressure. According to the national standard, the average life expectancy is 8000 hours. Some excellent products have reached 13,000 hours of life.

Generally, it is disinfected once a day, before the children arrive at school or after school, for 30 minutes to an hour at a time.

The baby's physical health is a special concern for every parent, and when the baby goes to kindergarten, the bacterial condition of the kindergarten tableware is also a problem that parents are worried about. Therefore, for the kindergarten staff, it is necessary to regularly disinfect the tableware used by the children in the kindergarten, and if it is not disinfected in time, it will cause gastrointestinal diseases in children. And in the process of sterilizing kindergarten tableware, what is the correct disinfection method?

The tableware in the kindergarten usually needs to be disinfected the most, otherwise it will cause many diseases, the most common is diarrhea.

The general tableware requirements for kindergartens are: tableware must be disinfected once every meal.

What are the methods of disinfection of tableware in kindergarten?

We share with you some common methods for kindergartens to choose from.

Method 1: Boiling disinfection method: Cover the item with water, soak for 15 minutes after boiling.

Method 2: Steam method: steam for 30 minutes after boiling water.

Method 3: Soak in disinfectant solution for 5 10 minutes.

Method 4: Disinfection cabinet disinfection.

Generally, it is more economical to choose a disinfection cabinet, and the disinfection effect is also very good.

This kindergarten tableware disinfection must be paid attention to, especially in summer, due to the large number of mosquitoes, if not often disinfected, it is easy to cause kindergarten students to have collective diarrhea.

Kindergarten collective diarrhea accident is extremely common, if such a thing occurs, not only the parents of students will find the school, but also the department will investigate the kindergarten, and even revoke the kindergarten.

Therefore, the daily disinfection of the kindergarten must be paid attention to and must be carried out.

Common methods of tableware disinfection:

1. Boiling and disinfection: put the washed and clean tableware in boiling water for 2-5 minutes;

2. Steam disinfection: put the washed and clean tableware into the steam cabinet or box, and disinfect it for 5-10 minutes when the temperature rises to 100;

3. Oven disinfection: such as infrared disinfection cabinet, etc., the temperature is generally about 120, and the disinfection takes 15-20 minutes.

4. Chemical disinfection: even if there is a lot of tableware disinfection with tableware disinfectant.

Ultraviolet disinfection is longer. Disinfectant can also be used.

Hope it helps!

Record the date of ultraviolet disinfection, the time when the lights are turned on, the time when the lights are turned off, the cumulative time and the signature of the disinfection personnel, which can be designed according to these contents, and record them in time after disinfection every day, which is very convenient.
