How much do you know about the damage andprotection of UV rays today, the staff of laser protective glasses bring us UVdamage and protection, because this is a question that we pay more and moreattention to. I hope this introduction can give us some help, then let's lookat what the specific content.
The wavelength of 100-400 nmelectromagnetic waves for ultraviolet spectrum, it is not visible to some onecan reach the ground ultraviolet wavelengths greater than 290 nm, shorter than290 nm ultraviolet light is absorbed by the ozone layer. In the productionenvironment as the object temperature above 1200 degrees, you can show theultraviolet radiation spectrum, such as smelting furnace, electric welding, gaswelding, mercury quartz lamp, ultraviolet lamp can emit ultraviolet. The effectof ultraviolet radiation on the body is related to the wavelength of radiation.Ultraviolet light has a great influence on the growth of human life and life.
Ultraviolet light can be divided into threeparts according to its wavelength:
Located between A wavelength 320-400 nm, AUV on our body is now on the composition effect of vitamin D have stimulativeeffect, but the A will lead to excessive ultraviolet light light inducedaggregation, restrain the immune system function, too little or lack of Aultraviolet light and simple with red and white cataract disease; B is locatedbetween 280-320 nm UV wavelength,
B UV impact to us body now make the skinbecomes red and short term decline in vitamin D production, long time bear maycause skin cancer, cataracts and restrain the immune system function;
C UV wavelength is located between 100-280nm; UV effects on humans are mainly reflected in the A UV and B UV inducedeffect. The UV index ultraviolet light intensity to the human body of the 0, 1,2 may affect the weakest security 3, 5, 6 and 4 weak normal medium 7, 8, 9 to10 strong strong strong body is beneficial to harmful ultraviolet side, alsohave harmful side. UV germicidal efficacy. The bacteria in the air and surfacebacteria by ultraviolet light can be killed after the time bound, the clinicaluse of the disinfection effect to the medical ward and. Excessive exposure toultraviolet light, harmful to the body. The effect on the skin such as UVfierce, can occur photodermatitis, skin erythema, itching, blisters, showingedema; the effect on the central nervous system, headache, dizziness, canpresent the temperature effect of advanced; in the eye, can causeconjunctivitis, keratitis, called photophthalmia. According to reports, a longtime a lot of exposure to ultraviolet rays can cause skin cancer and inducedcataract. With ultraviolet laser in medical, industrial processing is becomingmore and more widely used, the potential threat of ultraviolet light on day andnight increased. So in order to prevent ultraviolet damage, intense ultraviolettouch staff should take special protective masks, protective glasses andprotective gloves.
Theabove is the laser protective glasses for us to bring, for UV damage andprotection of the content. We hope that we will be able to help you in thefuture if we want to know more about the common sense and content of this kindof knowledge. Please pay more attention to us.
