Theapplication and characteristic of ultraviolet ray and infrared ray, ultravioletray and infrared ray is the laser with the most contact in our daily life, sowhat kind of application and characteristic does it have?. Ultravioletradiation is the electromagnetic wave wavelength is shorter than the purple,its main function is chemical action, infrared electromagnetic wave is betterthan red light wavelength, its main function is to heat effect, their spectrumis wide, but not a single frequency in a frequency range.
Infraredlight is an electromagnetic wave, when it goes through the way of radiationradiation to the object, by the radiation energy absorbed by the object istransmitted to the objects within the atoms and molecules that make theseparticles attack irregular movement, the heating effect caused by the object,called a far infrared effect, also known as the warming effect. Once the effectof the same time, the object will also occur in other chemical, physical andother changes, which is called the absorption of far infrared radiationproduced by the two effect, also known as secondary effects.
Infraredray on human skin, subcutaneous tissue with a penetrating force. Externalinfrared radiation produced by the human body can make the skin andsubcutaneous tissue of the corresponding increase in temperature, promote bloodcirculation and metabolism, promote human health.
Theeffect of infrared rays on the heat, anti-inflammatory and regeneration of thetissue has been affirmed by the clinic, and the effect of infrared rays on theskin is different from that of ultraviolet rays. Ultraviolet light is mainlycaused by photochemical reactions and optical immune response, and the infraredradiation generated by the reaction is due to molecular vibration andtemperature caused by the rise of. Infrared heat radiation caused by thepenetration of the skin beyond the uv. The amount of radiation of 25% ~ 65% canreach the epidermis and dermis, from 8% to 17% can reach subcutaneous tissue.
Infraredheat radiation through the effect of making the skin temperature,telangiectasia, congestion, increase skin water evaporation and other directimpact on the formation of skin. The main performance of red papules, prematureskin aging and pigment disorders. Increased skin temperature, telangiectasia,congestion, increase skin water evaporation and other direct impact on theformation of skin.
Infraredcan also strengthen the UV damage to the skin, accelerate the aging process ofthe skin. Use the same sunscreen products and the same energy UV radiationintensity, the measured outdoors under natural sunlight SPF value (SPF) wassignificantly lower than that of the sunscreen efficacy measured in thelaboratory under artificial light, which is due to natural sunlight, the dualrole of the skin by ultraviolet and infrared line caused. The effect ofinfrared rays and ultraviolet rays on accelerating tissue degeneration is the same.Infrared can also promote the development of UV induced skin cancer.
