The harm of ultraviolet disinfection lamp to human body?

Ultraviolet disinfection lamp, many people know but really know really know less and less. Uv application has gained popularity in life, such as counterfeit detector, disinfection cabinet, chemical paint curing, instrument analysis and ultraviolet disinfection, ultraviolet sterilizer is mainly to meet in pipes, water flow through the uv sterilizer tube body, the water to kill microorganisms will be ultraviolet radiation, safe and effective, is drinking water, domestic water efficient disinfection equipment. After uv sterilizer is very easy to use and install, open the power switch, in-line uv lamp work, then automatically for antivirus operations through the water. A, principle of work: the hair of spectral lines are mainly 254 nm ( UVC) And 185 nm ( UVD) Two, 254 nm by exposure to the sun's ultraviolet rays to kill bacteria microbial DNA, ozone disinfection lamp is to use 185 nm uv, a. 2 air into 3 ( Ozone) , ozone has strong oxidation, direct oxidation for bacterial cell body, namely damage while suppressing the effect of its DNA, RNA of virus also have damage, for a variety of toxins have certain oxidation, lower toxicity, which can effectively kill bacteria. Ozone diffuse just because ultraviolet ray propagation along a straight line only, can make up for disinfection has the defects of a corner. Second, what are the harm to human body? 1, on the skin damage is less than 220 nm wavelength ultraviolet ray is absorbed by the skin keratin layer all almost, wavelength of 280 nm uv, the strongest effect on the skin, can cause erythema reaction. Suffered from strong ultraviolet radiation, can produce diffuse erythema, itching or burning sensation, and can form vesicles or edema. Systemic symptoms such as headache, fatigue, general malaise. Regularly suffers ultraviolet irradiation and even run a risk of skin cancer. 2, damage to the eyes of 250 ~ 320 nm uv radiation can cause acute keratoconjunctivitis. It is also the eyes & other; Stealth killer & throughout; Only eyes, mild foreign body sensation and mild discomfort, severe burning sensation or eye pain, and have a high photophobia, tears, etc. Caused repeated ultraviolet radiation, can cause chronic conjunctivitis, corneal deformation caused by visual impairment, long-term exposure may cause cataracts. Don't look straight tubes, ultraviolet germicidal lamp light because shortwave ultraviolet not through ordinary glass, wearing glasses can avoid injury to the eye. If not narrow-minded injured, generally harmless, like the sun burned, serious eye drops it help to recover. Ultraviolet disinfection lamp does not reflect the harm of human body on the uv sterilizer, uv sterilization lamp installed inside the cylinder, the cylinder by food-grade 304 stainless steel pipe manufacturing, will not through the cylinder, so that in use process will not cause harm to human body, can be at ease use. Three, long time of irradiation to the body what consequences? 1, for a long time will have certain consequences of ultraviolet disinfection, such as damage to our skin, dermatitis or other may be some cancer, and so on all of these are possible. Of course there will be for our eyes hurt, such as cataracts. So we still don't long time to be is better, shorter the time may have the effect of disinfection, once after a long time will cause certain harm to us. 2, ultraviolet light for a few minutes, no effect, but if it is a long period of time under uv germicidal lamp, there is a harm to human body, in general, especially in the case of unprotected, ultraviolet radiation to human body harm is very big, easy to cause the electro-optic ophthalmia and dermatitis, if long time keep ultraviolet light skin, serious may produce canceration, so suggest to pay attention to the uv protection. Four, of medical ozone generated by the harm to human body? Ozone of strong oxidizing of harmful effects to human health. After ozone is believed to breathe, can quickly into a highly reactive free radicals - Super oxygen radicals ( O2- ) , mainly make the unsaturated fatty acid oxidation, leading to cell damage. Ozone can make the person's airway epithelial cells in the process of lipid peroxidation arachidonic acid increased, resulting in inflammation of the upper respiratory tract lesions, studies have shown that exposure to 0. 09 PPM ozone, vital capacity, forced vital capacity, and two hours later the first second forced vital capacity decreased significantly; Concentration of 0. 15 PPM, more than 80% of people felt eyes and nasal mucosa stimulation, 100% appear have a headache and chest discomfort. Because ozone can cause upper respiratory tract inflammation, damage to the terminal bronchioles epithelial cilia, which reduces the defence function of the upper respiratory tract, so long-term exposure to a certain concentration of ozone also is easy to be secondary to the upper respiratory tract infection. Ozone concentration in 2 parts per million, the short contact time can appear respiratory tract irritation, coughing, headache.
ultraviolet light suppliers is an inevitable and critical part of being a manufacturer, and it's more complicated than just manufacturing products and serving customers.
