Description
Technical field
The utility model relates to X-ray Testing Technology field, specifically a kind of for distinguishing the camera bag whether film exposes.
Background technology
Radiographic inspection is industrial to metal or nonmetal common method of carrying out testing for internal quality, it utilizes the high-energy ray such as X ray or gamma-rays to penetrate workpiece to be checked, its internal information is projected on film, then by after film rinsing, evaluation film image judges the defect such as crackle, pore, slag inclusion of inside workpiece.Film is encapsulated in camera bag usually, avoids it to be subject to the interference of visible ray light wave.But in the site work of reality, due to the confusing communication between the carelessness of operating personnel or different teams and groups, whether the camera bag be usually hard to tell at hand uses, and do not have again ready-made method to carry out differentiation checking to it, thus the egative film in a camera bag has been carried out the exposure of more than twice or twice by mistake, cause an egative film occurring two width or the above superimposed image of two width, " twins " that are namely commonly called as.Both waste film like this, waste man-hour again.
Utility model content
The utility model is for above problem, provides a kind of for distinguishing the camera bag whether film exposes.
The utility model solves the technical scheme that its technical matters adopts:
For distinguishing the camera bag whether film exposes, comprising camera bag body, being provided with Unidirectional transparent layer outside described camera bag body, the transparent surface of described Unidirectional transparent layer is coated with phosphor layers, and described phosphor layers is connected with outside described camera bag body.
Further, the material of described phosphor layers is phosphor powder or aluminate.
Further, the area of described Unidirectional transparent layer is greater than the area of described phosphor layers, and the edge of described Unidirectional transparent layer is pasted onto the edge of camera bag body side.
Described Unidirectional transparent layer comprises the Unidirectional transparent glass of Unidirectional transparent film, silver-plated or pad pasting.
The utility model camera bag dress is adopted to cut out film to be detected; Before exposing film, first observe in the dark state in the Unidirectional transparent layer on camera bag to have and do not have visible ray, as found, the phosphor layers of Unidirectional transparent layer inside has visible ray, then show that the film in this camera bag exposes; As there is no visible ray, then show that the film in this camera bag is unexposed.
In the utility model, Unidirectional transparent layer selects its side transmittance to be 0%, opposite side transmittance is greater than 70%, then the phosphorus being greater than one side coating 1-2 gram of 70% at its transmittance forms phosphor layers, with adhesive tape, the Unidirectional transparent layer being coated with phosphor layers is pasted and fixed on the outside of camera bag body not affect the position of film image again, make the light tight face of Unidirectional transparent layer expose to the open air in outside air, avoid the visible ray in phosphorus absorbing environmental.
Due to the electronics of phosphorus after absorption high-energy radiation by ground state transition to excited state, and at de excitation gradually of follow-up a period of time, and discharge visible ray in the process of de excitation.In ray detection work, operating personnel use X ray or gamma-rays to start exposure to the camera bag that film is housed, and the phosphorus now on camera bag starts to absorb high-energy ray, its internal electron by ground state transition to excited state; When after end exposure, the electronics de excitation of excited state falls after rise, constantly discharges visible ray in the process.If which operating personnel distinguish is used, then directly carry out follow-up work, if whether staff has used some camera bag threw doubt upon, or different teams and groups personnel are when taking mutually film and can not determine, only need (to cover in more black place or direct hand and expose an aperture) in the dark state and observe phosphorus and whether release visible ray and easily can distinguish whether this camera bag exposes, thus effectively prevent the generation of " twins " situation, save film and time.
Different phosphoruses have different stress time and de excitation time, different phosphoruses can be chosen according to the frequency of utilization of camera bag, conventional time shutter, to ensure its complete de excitation before using next time, thus reach avoid same film multiexposure, multiple exposure and can in lower task reusable object.During as needed to reuse at short notice when camera bag, the phosphorus of use including but not limited to II-VI race quick-acting phosphor powder in short-term taking zinc sulphide as representative, its firing time 3-15 second, sunset glow time 0.5-1 hour; When camera bag has longer use interval and time shutter, the phosphorus of use can be the aluminate being doped with rare earth element, its firing time 3-15 minute, sunset glow time 6-15 hour.
The utility model makes simple, and a camera bag body only needs phosphorus 1-2 gram, and it is with low cost, is worthy to be popularized.In addition, this camera bag can be reused.
