Description
Technical Field
The invention belongs to the technical field of ray detection, and particularly relates to a photoresponse label.
Background
The ray detection is a nondestructive flaw detection technology, and the principle is as follows: the object to be inspected is placed between the radiation source (X-ray or gamma ray) and the imaging negative (usually a film coated with silver iodide). Due to possible defects, the thickness or density of each part of the object to be detected may be different, and therefore, the weakening degree of the ray of the object to be detected is different. If the weakened ray is projected on an X-ray film, a picture (X-ray film) showing the thickness variation of the object and the internal defect condition can be obtained after development.
In the process of ray detection, multiple detections at the same position may occur due to operator errors, unsmooth communication and the like, and then the results of film waste, work time delay and the like occur. It is therefore desirable to develop a means to alert the operator whether a test has been performed at this point, avoiding repetition.
Disclosure of Invention
The present invention is directed to solving at least one of the problems of the prior art described above. To this end, the invention proposes an optically responsive tag, which is a disposable tag, which cannot be used for other detection points after one detection point uses one tag. In addition, after being irradiated by rays, the label can emit phosphorescence to display corresponding marks, and the marks correspond to the detection points one by one, so that an operator can be prompted, and repeated detection of the same detection point and omission of the detection points can be avoided.
According to one aspect of the present invention, there is provided an optical response label including a disposable adhesive layer, a luminescent layer, and a cover layer, which are sequentially disposed.
According to a preferred embodiment of the present invention, at least the following advantages are provided:
(1) according to the light response label provided by the invention, the disposable adhesive layer has strong adhesiveness and low strength, so that cohesive failure of the disposable adhesive layer can occur in the removal process; therefore, the disposable adhesive layer has the function of preventing transfer.
(2) According to the light response label provided by the invention, the light emitting layer has the effect of stimulated luminescence, so that when the detection site near the light response label is detected (irradiated by rays), the light emitting layer can continuously emit light to remind an operator, further, the repeated detection of the same site in the ray detection work can be avoided, and the work efficiency is improved.
In some embodiments of the present invention, the disposable adhesive layer is a composite layer composed of one or two of foam double faced adhesive tape and pearl cotton double faced adhesive tape.
The disposable adhesive layer is strong in cohesiveness and low in foam or pearl cotton strength, so that after the disposable adhesive layer is attached to the surface of an object, if removal is attempted, cohesive failure of the disposable adhesive layer can occur, and the disposable adhesive layer has an anti-transfer effect.
Because the disposable adhesive layer has the anti-transfer characteristic, the following phenomena are avoided: and manually transferring the label to the position easy to detect, and further detecting the position easy to detect for multiple times, and omitting detection at the position difficult to detect.
Because the disposable adhesive layer has elasticity, the luminous layer is embedded in the disposable adhesive layer, and the disposable adhesive layer also has the function of protecting the luminous layer.
In some embodiments of the present invention, the light-responsive label is further provided with a release layer which is opaque to light on a surface of the cover layer.
In some embodiments of the present invention, the release layer is at least one of black UV gloss oilpaper and black silicone oilpaper.
The release layer can protect the disposable adhesive layer from being polluted and maintain the viscosity.
The release layer can also prevent light from passing through, so that the failure of the luminous layer is avoided.
When the disposable probe is used, the release layer is peeled off, and the disposable adhesive layer is attached to the position nearby the to-be-detected site.
In some embodiments of the present invention, the material of the light emitting layer is a light emitting material, and the light emitting material emits light for more than or equal to 60 min.
In some embodiments of the present invention, the luminescent material comprises at least one of a sulfide, an oxide, and a phosphate.
In some embodiments of the present invention, the luminescent material comprises (ZnS: Cu), (ZnS: MnCu), (ZnS: Cu, Eu, Br), (CaS: Eu), (CaS: Ce), (MgAl)11O9:Ce、Tb)、(SrAl2O4: eu) and (Sr)0.78Eu0.22)O·2(Al0.73Dy0.2Ce0.07)2O3·0.6P2O5At leastOne kind of the medicine.
The luminous layer can continuously emit light for 60 min-15 h after receiving the irradiation of natural light, X rays or gamma rays, so that an operator can judge whether the detection is finished according to whether the photoresponse label emits phosphorescence or not in the process of ray detection, and further, the repeated operation and the work delay are avoided.
The visible light or ultraviolet light can also excite the luminescent material in the luminescent layer, so that the prompting effect of the light response label on a ray detection operator is influenced; therefore, the covering layer needs to have one-way light transmission, namely, one side facing the light emitting layer can transmit light, and the other side cannot transmit light; the light-emitting layer is not affected by natural light, and light emitted by the light-emitting layer can be observed.
In some embodiments of the present invention, the cover layer includes a microlens layer, a substrate layer, and a reflective layer, which are sequentially disposed from the vicinity of the light emitting layer, and the reflective layer is provided with a light transmitting hole.
In some preferred embodiments of the present invention, the microlens layer is composed of a plurality of lenses distributed in an array.
In some preferred embodiments of the present invention, the reflective layer is composed of a plurality of reflective surfaces distributed in an array.
In some embodiments of the present invention, the material of the substrate layer in the covering layer is glass or an organic material.
When natural light irradiates the reflecting layer, the natural light is reflected, that is, on the surface of the reflecting layer, the reflected light occupies most of the light, and the transmitted light occupies a small proportion, so that the reflecting layer is opaque; when light irradiates the micro-lens layer, the light passes through the lens layer and the light-transmitting holes, that is, the surface of the micro-lens layer is mostly transmitted, and the reflected light is a small part, so that the micro-lens layer can transmit light.
The micro lens also has a light-gathering effect, so that the gathering degree of the phosphorescence of the light-emitting layer is improved, and the observation by people is facilitated.
When the base material is glass, the glass has fragile property, so that the anti-transfer function is achieved.
In some embodiments of the present invention, the cover layer includes a refractive index adjustment layer and a glass layer stacked in this order from the light emitting layer, and the glass layer and the refractive index adjustment layer are fragile and have a function of preventing transfer.
In some embodiments of the present invention, the refractive index adjustment layer includes a first refractive layer having a refractive index of 1.5, a second refractive layer having a refractive index of 3.1, a third refractive layer having a refractive index of 1.2, a fourth refractive layer having a refractive index of 3.5, and a fifth refractive layer having a refractive index of 2.2, which are stacked in this order from the glass layer.
Because the sub-layers of the refractive index adjusting layer have different refractive indexes, two surfaces have different reflectivity to light, and one-way light transmission is realized, namely the surface of one side where the glass layer is located has strong reflectivity and weak transmissivity to light, and the surface of one side where the fifth refraction layer is located has strong transmissivity and weak reflectivity to light.
In some preferred embodiments of the present invention, the area of the cover layer is larger than the area of the light emitting layer in order to further protect the light emitting layer from excitation prior to use.
