Quartz ultraviolet lamp

UV disinfection technology has unparalleled sterilization efficiency compared to other technologies. The sterilization efficiency can reach 99% -99.9%. However, traditional chemical disinfection methods such as chlorine and ozone typically take 20 minutes to 1 hour to achieve the bactericidal effect of ultraviolet C. Ultraviolet is a low energy electromagnetic radiation with a wavelength of 200-275nm. Ultraviolet sterilization lamp is a medical device that uses ultraviolet radiation for light sterilization, and its intensity should not be less than 70 μ W／c m2。 The suitable sterilization temperature is 15 ° C-40~C, and the relative humidity is 50%~60%. However, its scope of action is limited to the shallow surface of the object, and it can only have an effect in places and spaces where ultraviolet light radiates. Moreover, ultraviolet light has a certain stimulating effect on the eyes and skin of people.

When hospitals carry out air sterilization, ultraviolet sterilization lamps are generally used, and their ignition principle is similar to that of ordinary lighting eye lamps. It has the advantages of strong sterilization effect, convenient use, simplicity, portability, low cost, and easy popularization. The principle of its luminescence is to fill a vacuum treated quartz glass tube with mercury vapor, and the lamp tube is equipped with filaments at both ends. By applying voltage to both ends of the filament through a ballast, the mercury gas arc discharge is excited to generate ultraviolet light. The ultraviolet wavelength of ultraviolet tubes for medical sterilization is 254nm. Ultraviolet disinfection lamp refers to the use of ultraviolet light to kill bacterial propagules, spores, mycobacteria, coronaviruses, fungi, rickettsia, and chlamydia. Any surface, water, and air contaminated by these viruses can be disinfected with ultraviolet light.

1. The effective life of hot cathode is 8000 hours, and that of cold cathode is more than 20000 hours.

2. High quality quartz glass tube with a hydroxyl content of less than or equal to 50ppm and a UV transmittance of 90% or more.

3. Zirconium aluminum sheet technology can adsorb impurities in the tube and extend its service life.

4. Ultra low mercury technology, with a mercury content of less than or equal to 5mg, meeting EU standards.

1. Applicable scope

Mainly used for disinfection and sterilization (for air, objects, and water) and sewage treatment (environmental governance). In addition, it has many special uses such as bleaching, water decolorization, odor removal, participating in industrial oxidation reactions, and treating diseases.

2. Sterilization mechanism

Ozone is a strong oxidant, and the process of ozone sterilization belongs to biochemical oxidation reactions. There are three ways: ozone can oxidize and decompose the enzymes necessary for the internal oxidation of glucose in bacteria, causing them to inactivate and die; Directly interacting with bacteria and viruses, destroying their cell walls, DNA and RNA, disrupting bacterial metabolism and leading to death. (DNA ribonucleic acid; RNA deoxyribonucleic acid. A virus is a large molecule wrapped in a protein and contains only one type of nucleic acid. Extracted from "Fundamentals of Microbiology", Chemical Press, 1994 edition). Penetrating the cell membrane tissue, invading the lipoproteins acting on the outer membrane and lipopolysaccharides inside the cell membrane, causing bacterial permeability distortion and dissolution and death.

3. Advantages

Efficient and broad-spectrum. Ozone sterilization belongs to the bacteriolytic grade, with thorough sterilization, no residue, and a broad spectrum of sterilization. It can kill bacterial propagules, spores, viruses, fungi, etc., and can also destroy botulinum toxin. It not only has a strong killing effect on various bacteria, but also is very effective in killing molds.

Green sterilization, pollution-free. Ozone has poor stability and quickly decomposes into oxygen and individual oxygen atoms. A single oxygen atom combines to form an oxygen molecule without any toxic residue, so it is called a pollution-free disinfectant.

No dead corners. Ozone is a gas that can quickly diffuse throughout the entire sterilization space from top to bottom, with no blind spots during sterilization.

The killing effect of ozone on pyrogens. Ozone can not only directly kill viruses, but also kill pyrogenic viruses by killing the bacteria and microorganisms they parasitize.

4. Environmental requirements

It should not be used in the following places: places with direct contact with flammable and explosive gases (if necessary, gas conversion should be carried out in advance); Places with excessive dust; Places above 50 ℃ or below -20 ℃; Ozone generators in places with high humidity should be evacuated after operation.

5. Disadvantages and Prevention of Ozone Sterilization

Ozone has oxidizing properties on objects, mainly causing certain corrosion to natural rubber or natural rubber products, as well as copper products (in the presence of water vapor). For other materials, weak corrosion due to short ozone sterilization time can be ignored;

When the ozone generator is working, it is not advisable to introduce flammable gases that exceed the explosion limit;

The penetration of ozone is weak, and its ability to kill bacteria in the vertical depth of objects is low; Exposed materials and products with strong adsorption properties can affect the flavor of the product.

Application scope: This product has been used for sterilization and disinfection in medical, industrial and other fields for a long time, and the effectiveness of its application is naturally beyond doubt! Due to the wide range of applications of this product, I will briefly introduce it to you specifically for household use.

We suggest you use it in the following situations at home!

1. If there are patients at home (especially those with infectious or respiratory diseases)

2. For the elderly in the family

3. Having infants and young children at home

4. Living in a basement, semi basement, not ventilated, rarely able to reach sunlight.

5. Keep pets or other small animals at home

6. Family members have weak resistance and are prone to catching colds or diarrhea

7. The family has skin diseases. (Effective in killing mites)

8. The bathroom or kitchen at home is not ventilated and cannot be exposed to sunlight for years.

9. After hunting reptiles at home.

10. Disinfect before staying at home for a long time or moving into a new house! Family room disinfection (especially in shaded rooms where sunlight is not visible) thoroughly disinfects the indoor air of bedding, furniture, and supplies through ultraviolet radiation. Elderly, infants, patients, and pets in the home should be disinfected and disinfected regularly for a long time to ensure better family health.

This product can effectively disinfect rooms of 10-15 square meters. Please press the timer to leave the room and close the door in a timely manner (make sure to disinfect in an unoccupied room). Ultraviolet rays can burn your eyes and skin and avoid looking directly at the lit lamp tube with your eyes. After about 70 minutes of opening, this product automatically turns off, and you can enter the room. After disinfection, the indoor air is fresh and there is no need to open windows for ventilation.
