Protective plate material for X ray

Abstract

A method for preparing X ray protection slab includes mixing magnesium sulfate with water as per certain ratio uniformly, adding a match amount of lead oxide or iron oxide in mixed material, agitating said material uniformly to be a semi-fluid adhesion matter with shielding function and then using template to form said semi-fluid adhesion matter for obtaining protection slab.

Description

technical field [0001] The invention relates to a radiation protection material and a production method thereof, in particular to an X-ray protection plate and a production method thereof. Background technique [0002] With the development of science and technology, all kinds of radiation are widely used in various fields of economic development, especially in medicine, scientific research, equipment flaw detection, etc., where hospitals generally use X-rays as orthopedic diagnosis One of the methods, but long-term exposure to X-rays will cause certain harm to the human body, so special radiation protection measures will be adopted in hospitals and other units that use X-rays. [0003] The traditional protective material is lead, but due to the low mechanical properties and soft texture of pure lead, its products are easy to deform and sag, so it cannot be used alone as a protective material.

AI Technical Summary

Problems solved by technology

[0003] The traditional protective material is lead, but due to the low mechanical properties and soft texture of pure lead, its products are easy to deform and sag, so it cannot be used alone as a protective material

In the prior art, some use other materials as the inner lining bracket, and the outer lead skin is used as the plate of the protective material. Although this can achieve a certain protective effect, the lead is completely exposed to the air and is very easy to be oxidized, resulting in long-term exposure. Lead poisoning of relevant personnel in this environment will seriously affect their health

In the process of making the protective plate, it is necessary to fix it with nails, etc., which will result in poor protection effect at the nail hole, and even cause radiation leakage

Another is to use lead and barium compounds as shielding materials and process them into radiation shields. However, the raw materials of such products are not easy to prepare, the production cost is high, and they are easy to deform, especially in humid environments. , Anti-alkali and anti-halogen are very serious, seriously affecting the service life of the protective plate

In the prior art, in order to avoid the occurrence of anti-alkali and anti-halogen phenomena, the board after demoulding and shaping is immersed in water for 24-48 hours, and then it can be used after at least 24 hours of drying procedure, which not only prolongs the manufacturing cycle, but also There are still frequent anti-alkali and anti-halogen phenomena, and the effect is not very satisfactory
