1, the ultraviolet ray of ultraviolet disinfection lamp will have a certain influence on human body irradiation, so it cannot directly irradiate human body. Pay attention to let the children leave when disinfecting.

2, ultraviolet irradiation should have time limit, and ensure sufficient ultraviolet intensity, irradiation time is generally 30~60 minutes. Every cubic meter needs 1.5w ultraviolet disinfection lamp, that is, every 20 cubic meters of space needs a 30W ultraviolet disinfection lamp, and so on.

3. The environment also has an influence on the sterilization effect of the ultraviolet disinfection lamp, and the output intensity of ultraviolet rays is the largest when the temperature is between 27 degrees Celsius and 40 degrees Celsius. High humidity or dust will reduce the sterilization ability of the disinfection lamp. Therefore, the sterilization environment needs to be kept clean and dry. Disinfection lamps need to be wiped with alcohol every two weeks.

4, often need to replace the disinfection lamp, ultraviolet disinfection lamp has slow leakage phenomenon, after using 8000 hours, need to replace the lamp in time, usually once a year.

It's best to close the doors and windows, close the curtains, open the quilt, books, etc. When using ultraviolet disinfection lamp to achieve the best sterilization effect.

Matters needing attention

1, it must be electrified for 3~ 10min, and it can be applied only after the luminescence is stable.

2. Don't let ultraviolet rays shine on your eyes to avoid injury.

3. When loading and unloading the lamp tube, avoid direct contact with the surface of the lamp tube by hand, so as to avoid timely pollution and affect its ability to penetrate ultraviolet rays.

4, should often use gauze or absorbent cotton dipped in alcohol to wipe the lamp, to keep its surface clean and transparent.

Extended data

The advantages of ultraviolet disinfection are as follows:

1, the physical and chemical properties of water are basically unchanged without introducing impurities into the water;

2. The chemical composition of water (such as chlorine content) and temperature changes generally do not affect the disinfection effect;

3, does not increase the smell and taste in water, and does not produce disinfection by-products such as trihalomethane;

4. Wide sterilization range, high speed and short treatment time. Under a certain radiation intensity, common pathogenic microorganisms can be killed in just over ten seconds, which can kill some germs that cannot be inactivated by chlorine disinfection, and also have a certain control effect on some higher aquatic organisms such as algae and red worms.
