How is uv germicidal lamp germicidal?

  The principle of sterilization of uv germicidal lamp

Uv germicidal lamp and fluorescent lamp luminescence principle is the same, mercury atoms in the lamp tube are excited attack mercury characteristic spectrum line, low pressure mercury vapor first attack 254nm and 185nm ultraviolet, sterilization lamp lamp tube is made of permeable purple glass or quartz glass, make ultraviolet light through the lamp tube transmission.

The 254-nm wavelength of ultraviolet light is simply absorbed by the object, and the effect is on the genetic material of the organism‘s DNA, causing the DNA to be damaged and causing the bacteria to die.

The 185nm wavelength of ultraviolet light and air effect can attack a strong oxidizing effect of ozone, can be used to kill bacteria, and ultraviolet light can meet a very high intensity, in a short time to kill bacteria and viruses.
 

Common use of uv germicidal lamp

Uv germicidal lamp germicidal use is very wide, hospital, school, nursery, cinema, bus, office, home, it can purify air, eliminate musty flavour, still can produce a certain amount of negative oxygen ion in addition.

The air in the room sterilized by ultraviolet ray is very fresh. In public places, through ultraviolet disinfection, can avoid some germs by air or by the object surface spread.
 

Correct use of uv germicidal lamp

1. Sterilization of the surface of articles

Special lamps and lanterns are used for assembling ultraviolet light source. The ultraviolet lamp produced by professional manufacturers can greatly reduce the injury accidents caused by ultraviolet lamp radiation. Below the condition that nobody is in the room, can take uv germicidal lamp to hang type illuminate, below satisfying illuminate condition, had better use uv germicidal lamp close range illuminate, should make the object surface that be irradiated by ultraviolet ray direct illuminate, and should achieve sufficient illuminate dose. The irradiation time should not be less than 30 minutes to effectively sterilize the irradiation area.

2. Sterilize the air in public places

(1) Irradiation mode and time. Under the condition of unmanned, the uv germicidal lamp can be used to suspend or mobile direct irradiation to kill pathogens that may adhere to the air suspension and object surface. The effective irradiation distance should not be less than 1 meter when indoor hanging uv germicidal lamp is used for disinfection. The exposure time shall not be less than 30 minutes.

(2) In the process of use, should keep the surface of uv germicidal lamp clean, generally every 1 to 2 weeks will be wiped with alcohol cotton ball, timely clean lamp tube surface dust, oil. 

(3) When sterilizing indoor air with uv germicidal lamp, the indoor should be kept clean and dry to reduce dust and water mist. The indoor temperature should be kept between 20°C and 40°C. When the relative humidity is more than 60%, the irradiation time should be appropriately extended.

(4) After irradiation, open the window for ventilation for 20 minutes.
 

Protective measures and first aid measures of using ultraviolet sterilizing lamp

In the use process, we should pay attention to the following points:

(1) Uv germicidal lamp can be considered to sterilize and disinfect articles that may carry pathogens.

(2) In the process of sterilization lamp use, avoid direct irradiation of the human body or plants and animals, to prevent skin burns or plant wilt.

(3) Do not look directly at the ultraviolet lamp tube to prevent eye swelling or burns.

(4) After the completion of disinfection, it is recommended to ventilate the room for 20-30 minutes.

(5) Buy professional uv germicidal lamp manufacturers qualified and effective products, understand the installation requirements of ultraviolet products, in order to ensure the reasonable and effective use of ultraviolet lamp.
