Abstract
The utility model relates to a lead-free and environment-friendly high energy ray shielding container which comprises a container body, a lining cover and a shield cover, wherein the container body, the lining cover and the shield cover are made of shielding materials in injection molding or hot extrusion molding. A groove is arranged in an opening of the container body. A flange which is matched with the groove in shape and size is arranged on the lower edge of the shield cover. The shield cover covers above the container body, the lining cover is arranged between the container body and the shield cover, and therefore the space formed after combination can be used for storage and prevention of a high energy ray source. After the shield cover is taken off, the lining cover can effectively shield high energy ray slanting and protect an operator. The lead-free and environment-friendly high energy ray shielding container effectively avoids the problems of lead pollution and high cost of tungsten alloy processing, has the advantages of being good in high energy ray shielding effect, free of lead and environment-friendly and can be used in the field of detection, a chemical industry, security, medical treatment and a nuclear industry.
Description
Technical field
The utility model relates to the alpha ray shield technical field, particularly relates to a kind of leadless environment-friendly high-energy ray cask flask, has the storage of high-energy ray field of employment, protective shielding container mainly for detection of, security, medical treatment, chemical industry, nuclear industry field.
Background technology
In recent years, lead-containing materials has a wide range of applications in industry, and its toxicity affects the mankind and other biology day by day.A large amount of high pollution, high toxicity, low intensive lead that use will be eliminated rapidly at present; And the tungstenic material of high comprehensive performance, environment-protecting asepsis will be optimal equivalent material.Pure tungsten or its alloy have good X ray shield effectiveness, but its fusing point are higher, the machine-shaping difficulty, and poor toughness, matter is crisp, and shape and size are revised more complicated after the moulding.Therefore, be difficult to utilize tungsten or its alloy to be made into the cask flask of complicated shape.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of leadless environment-friendly high-energy ray cask flask, conveniently radiant matter is got dress.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of leadless environment-friendly high-energy ray cask flask is provided, comprises vessel, lining lid and cover cap by shielding material injection mo(u)lding or hot extrusion molding; Described vessel opening part is provided with groove; Described cover cap lower edge is provided with the flange that cooperatively interacts with described groove shapes size; Described cover cap covers on described vessel top; Perforate in the middle of the described lining lid, and between described vessel and cover cap.Described lining covers can effectively shield the high-energy ray oblique fire, the protection operator after cover cap takes away.
Described shielding material is nylon 6 engineering plastic, is surrounded by tungsten powder or tungalloy powder in the described nylon 6 engineering plastic.
The profile of described leadless environment-friendly high-energy ray cask flask is spherical, or cylindricality, or square.
Tungsten (or tungalloy) powder/nylon 6 composite material has good high-energy ray screening ability, but is the nylon 6(PA6 that injection moulding is extruded) the engineering plastics tungsten powder or its alloyed powder that coat difficult moulding be prepared from.This compound substance is to have good high-energy ray shielding material, and X ray, gamma-rays and radioactive isotope radiation are had excellent attenuation and absorption ability, can be suitable with lead.Utilize this compound substance, can be injection molded into that the complicated high-energy ray (source) of shape stores, shielding container, have widely in fields such as medical science diagnosis and treatment, nuclear energy uses, article safety check, industrial flaw detections, potential application.
Beneficial effect
Owing to adopted above-mentioned technical scheme, the utility model compared with prior art, have following advantage and good effect: the utility model utilizes tungsten (or tungalloy) powder/nylon 6 composite material, by injection moulding or hot extrusion, the preparation of the techniques such as cast is than the advantage of complicated shape, the leadless environment-friendly high-energy ray cask flask that obtains comprising vessel and cover the cover cap of radiation source efficiently solves tungsten (or tungalloy) and is difficult to processing, has avoided using the plumbous pollution that brings.Wherein, tungsten (or tungalloy) powder/nylon 6 composite material Mi Du＞=10.0g/cm
3, shielding properties is with quite plumbous, and radiation resistance is good.
Description of drawings
Fig. 1 is structure cut-open view of the present utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment of the present utility model relates to a kind of leadless environment-friendly high-energy ray cask flask, as shown in Figure 1, comprises by the vessel 1 of shielding material injection mo(u)lding or hot extrusion molding, lining and covers 2 and cover the cover cap 3 of radiation source.Described vessel 1 opening part is provided with groove, and described cover cap 3 lower edges are provided with the flange that cooperatively interacts with described groove shapes size, and vessel 1 can concavo-convexly match with cover cap 3, and formed space can be used as storage after the combination, the protection high-energy ray is used.Described lining lid 2 can effectively shield the high-energy ray oblique fire after cover cap 3 takes away, the protection operator.The nylon 6(PA6 that injection moulding is extruded but shielding material is the high-energy ray shielding composite) the engineering plastics tungsten powder or its alloyed powder that coat difficult moulding be prepared from.That is to say that shielding material is nylon 6 engineering plastic, be surrounded by tungsten powder or tungalloy powder in the described nylon 6 engineering plastic.This Realization of Product be to adopt certain pressure, with tungsten (or tungalloy) powder/nylon 6 composite material at a certain temperature, injection moulding or hot extrusion, cast forms.This leadless environment-friendly high-energy ray cask flask has been avoided the leakage of high-energy ray, and shield effectiveness is good, can be used for detecting chemical industry, security, the fields such as medical treatment, nuclear industry.The profile of the high-energy ray of leadless environment-friendly described in Fig. 1 cask flask is cylindricality, need to prove, profile of the present utility model can also be other shapes such as spherical or square, and concrete shape can be made as required.
