A kind of anti-radiation stainless steel plate and its preparation method and application

Abstract

The invention provides a radiation-resistant stainless steel plate, which is prepared by injection molding or compression molding after mixing several composite balls and stainless steel powder, wherein the structure of the composite ball includes a hollow spherical shell and a core, and the inner wall of the hollow spherical shell There is a gap between the core and the inner core; the anti-radiation stainless steel plate provided by the present invention is made by mixing composite balls with the ability to shield gamma rays and neutrons with stainless steel powder, which reduces the weight of the plate on the one hand. Density, on the other hand, makes the plate have the ability to shield gamma rays and neutrons at the same time, and, because the interior of the composite ball has a gap, there is room for the helium generated when shielding and absorbing neutrons, effectively avoiding the helium Cracks occur inside the plate, which can increase the boron content of the plate, thereby improving the ability to shield and absorb neutrons.

Description

technical field [0001] The present application relates to the field of anti-radiation materials, in particular, to a anti-radiation stainless steel plate and a preparation method and application thereof. Background technique [0002] Traditional anti-nuclear radiation materials usually include lead, steel, and cement, but the proportion of the above materials is relatively large, which makes the anti-radiation equipment prepared from them very heavy and wastes resources. The process will not only pollute the environment, but also cause harm to the operator's body. In addition, due to the many types of radiation, lead and cadmium have better protection against gamma rays, but weaker protection against high-energy neutrons, and boron has better protection against neutrons, but In the prior art, the content of boron in the steel is less than 2%, because when boron processes neutrons, helium gas is generated, and helium gas is generated inside the material, which is easy to cau...

AI Technical Summary

Problems solved by technology

[0002] Traditional anti-nuclear radiation materials usually include lead, steel, and cement, but the specific gravity of the above-mentioned materials makes the anti-radiation equipment prepared from them very bulky, and the large amount of use is a waste of resources, and both lead and cadmium are toxic substances. The process will not only pollute the environment, but also cause harm to the health of the operators.

In addition, because there are many types of radiation, lead and cadmium have better protection ability to gamma rays, but weaker protection ability to high-energy neutrons, and boron element has better protection ability to neutrons, but In the prior art, the boron content in steel is less than 2%, because boron will generate helium gas when it processes neutrons, and the helium gas is generated inside the material, which is easy to cause material cracking, resulting in nuclear radiation leakage, so boron The content can only be in a lower range, resulting in poor neutron protection
