Protective structure and mounting technology of ray protective wall

Abstract

The invention belongs to the technical field of ray protecting, and discloses a protective structure of a ray protective wall. The protective structure of the ray protective wall comprises a wall body, and further comprises a ray protective layer arranged to be attached to the wall surface of the wall body and a fixing structure fixedly connecting the ray protective layer and the wall body. An independent fixing structure is adopted to be connected with the wall body, so that the ray protective layer is stably arranged to be attached to the wall body, the method of traditionally adopting a rayprotective material to conduct whitewashing on the wall body is overturned, and the problem of protective defects caused by cracking of the painted wall bodies is effectively avoided; protruding structures and groove structures on ray protective bricks are designed in a mutually fit mode, especially the protruding structures adopt sine curve structures, thus the situation that rays penetrate through gaps in connecting positions between the bricks can be totally prevented, seamless joint is formed between the ray protective bricks, and the effect that the rays are totally prevented after the ray protective bricks are piled is ensured; and the ray protective layer poured through ray protective slurry is high in compactness, the ray protective function is excellent, operation is easy, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of radiation protection, in particular to a protection structure and an installation process of a radiation protection wall. Background technique [0002] With the wide application of radiation in medical and health, national defense, scientific research, industry, agriculture and other fields, especially X-rays have become the most widely used ionizing radiation. Radiation technology has brought huge economic benefits to society, but on the other hand, Due to its high energy and strong penetrating power, it has different degrees of damage to human physiological functions, and the definition of radiation brought by it is also known to the general public, so it is particularly important to do a good job in radiation protection projects. [0003] The traditional X-ray protective material is lead, but lead is poisonous, has poor mechanical properties, unstable geometric dimensions, is easy to deform, sag, and i...

AI Technical Summary

Problems solved by technology

[0003] The traditional X-ray protective material is lead, but lead is poisonous, has poor mechanical properties, unstable geometric dimensions, is easy to deform, sag, and is not shockproof, and it is easy to creep after a long time. Therefore, lead cannot be constructed alone, and clamping materials must be used. made, and the proportion of lead is large, resources are relatively scarce, the cost of use is high and the construction procedure is complicated

[0004] The radiation protection wall in the prior art generally achieves the purpose of shielding radiation by painting the wall. The plastering material is mixed with barium sulfate powder and curing agent into a viscous shape, and then the viscous shielding material is painted on the wall. However, the thickness of this kind of wall painting is usually not enough, the shielding effect is average, and the painted wall is easy to crack, forming a space for rays to escape, so painting the wall requires a lot of maintenance costs

[0005] X-ray shielding protective plates have also appeared in the prior art, and plates are used to replace walls, but the specifications and sizes of plates are highly targeted, and quantitative production cannot be produced, and the production process is complicated, requiring the use of various shielding agents and adhesives and other materials are mixed to obtain the required composite sheet. For example, in the prior art, there is a sheet made of quartz powder, zinc powder, sulphoaluminate cement, barium sulfate and other raw materials through complex processes. It is light in weight, The effect of absorbing X-rays is good, but sulfoaluminate cement is a special cement, the source of raw materials is limited, and the production cost is high. Secondly, in order to make it easy to generate air bubbles in the production process, so that there are pores inside the board, zinc powder is added to the raw materials , in order to achieve the effect of thermal insulation, sound insulation and light weight, but this kind of process control is difficult, and it is difficult to obtain a shielding protective plate (wall) that meets the overall shielding effect. stability
