Description
Technical field
The utility model belongs to photochemistry and material science, be specifically related to a kind of ultraviolet ray spot strength indicator mainly being formed by photochromic layer and slide glass, especially a kind of when touching ultraviolet ray, can be by the ultraviolet existence of variable color visually-perceptible, and the difference of different perception uitraviolet intensities that can be by variable color color, warning user carries out the indicating device of the ultraviolet protection of different stage.
Background technology
Ultraviolet ray is the general name of electromagnetic wave spectrum medium wavelength from 10nm to 400nm radiation, can not directly cause people's vision.It is physioptial a kind of that ultraviolet ray belongs to.Natural main ultraviolet ray source is the sun, and artificial ultraviolet light source can be produced by multiple gases arc source (as low pressure mercury arc, high-pressure mercury arc lamp).Ultraviolet ray is divided into according to wavelength: near ultraviolet ray UVA, middle-ultraviolet lamp UVB and far ultraviolet UVC.The ultraviolet ray of different wave length is different to the penetration degree of human body skin.Ultraviolet wavelength is shorter, and larger to human skin harm, short wave ultraviolet can pass corium.
Far ultraviolet: being called for short UVC, being also called short wave ultraviolet, is the ultraviolet light of wavelength 200-280nm.Short wave ultraviolet is absorbed by ozonosphere when through earth surface stratosphere, can not reach earth surface.
Middle-ultraviolet lamp: being called for short UVB, is the ultraviolet light of wavelength 280-320nm.This type of ultraviolet very big part is absorbed by epiderm skin, can not infiltrate skin inside again.Because it is containing can be higher, to skin, can produce strong optical damage, the corium blood vessel dilatation of illuminated position, can there is the symptoms such as redness, bubble in skin.The permanent skin that irradiates there will be erythema, inflammation, skin aging, and severe patient can cause cutaneum carcinoma.Ultraviolet B radiation is known as again ultraviolet sunburn (red) section, is the ultraviolet wave band of answering emphasis prevention.
Near ultraviolet ray: being called for short UVA, is the near ultraviolet ray of wavelength 320-400nm.Near ultraviolet ray is eager to excel more than ultraviolet B radiation to the penetrability of clothing and human body skin, and the melanin that can reach deep dermis ，Bing Ke his-and-hers watches skin zone position works; thereby cause that dermal melanin is calm; make skin darkening, played defence ultraviolet ray, the effect of protection skin.Thereby long wave ultraviolet is also known as " tanned section ".Though near ultraviolet ray can not cause skin acute inflammation, slow to the effect of skin, can accumulate for a long time, be one of reason causing skin aging and grievous injury.
As can be seen here, preventing the skin damage that ultraviolet ray irradiation causes to human body, is mainly the irradiation that prevents ultraviolet (UV) B; And prevent UVA ultraviolet ray, be for fear of skin tanning.America and Europe, it is believed that skin pitch-dark be vigorous and graceful symbol, so will add suntan on the contrary in cosmetics, and do not consider the protection to long wave ultraviolet.This viewpoint changes in recent years, owing to recognizing that long wave ultraviolet is to the issuable long-term grievous injury of human body, so people start to strengthen the protection to long wave ultraviolet.When ultraviolet ray is irradiated, degree and time that eyes are injured are directly proportional, be inversely proportional to the square distance of irradiation source, and relevant with the crevice projection angle of light.When skin, can there is photodermatitis in ultraviolet ray strong effect, occur erythema, itch, blister, oedema, ophthalmodynia, shed tears etc. on skin; Serious also can cause cutaneum carcinoma.In central nervous system, can there are headache, dizziness, hyperthermia etc. in action of ultraviolet radiation.Act on eye, can cause conjunctivitis, keratitis, be called photophthalmia, also likely bring out cataract, the ultraviolet ray producing in welding process can make welder suffer from electric ophthalmia.
For ultraviolet radiation measuring method; more general measuring technique is to adopt photoelectric sensor method now; sunray is by sensor protection window; through ultraviolet filter film; only have the ultraviolet light of a wave band can penetrate filter coating; other wave band light ray cut; semiconductor ultraviolet detection device changes the ultraviolet signal seeing through into electric signal output; through converter, send into single-chip microcomputer, process as calculated, finally result output display [is recorded in: Elaine Chao; Nie Fei; Malaysian is glad etc. electronic measurement technique, 2008,31 (1): 112-114.].
At present, also there are some to adopt photochemistry variable color to measure ultraviolet method, such as forming with chlorinated polymers (as PVC) and leuco dye, chlorinated polymers is subject to ultraviolet radiation to discharge HCl acid source, acid source will make leuco dye colour developing and play indicative function and [be recorded in: Qian Shuijuan, Hong Guisheng. imaging material, 1986,5:019.], the method actual measurement be the radiation dose of ultraviolet radiation, when measured intensity, must be fixedly radiated time, then it is compared with standard color block, there is comparability its numerical value side; A shortcoming of the method is that reaction is irreversible, and indicator is disposable use only, must not reuse.
Granted publication number is made ultraviolet ray indication film for the disclosed technical scheme employing of the Chinese utility model patent ability of reverse photochromism compound of CN202396661U, can be affixed in articles for daily use, is applicable to for warning pre-antiultraviolet, avoids skin tanning; It does not limit access times, can unlimitedly use in theory.But because uitraviolet intensity is only relevant with its variable color degree of depth, color distortion is also little, so vision insensitive.
