Flexible nuclear radiation protecting screen

Abstract

The invention relates to a flexible nuclear radiation protecting screen which consists of a flexible metal inner core layer and two nonmetal coating layers, wherein the flexible metal inner core layer is packaged between the two nonmetal coating layers; the flexible metal inner core layer is three-dimensionally weaved by compound flexible alloy fibers; the compound flexible alloy fibers comprise metal inner core fibers and reticular-structure carbon fibers coating the metal inner core fibers; the metal inner core fibers comprise at least one lead alloy fiber, tungsten alloy fiber or tantalum alloy fiber; the nonmetal coating layer is formed by a thermoplastic resin and reticular reinforced fiber cloth in the thermoplastic resin through hot rolling; a hole and a round grommet are arranged at the edge part of the flexible nuclear radiation protecting screen. The flexible nuclear radiation protecting screen has excellent nuclear radiation protecting property, has the functions of retarding flame, preventing the inner core from fracturing and falling, resisting oil, preventing puncture and decontaminating, and can be widely applied to the daily radiation protection and nuclear emergency protection in the fields of nuclear stations, hospitals and military nuclear equipment.

Description

[0001] technical field [0002] The invention relates to the technical field of nuclear radiation protection, in particular to a flexible nuclear radiation protection screen. [0003] Background technique [0004] Nuclear science and technology have been widely used in many fields such as national defense, energy, industry, and medical treatment, bringing huge economic and social benefits, and increasing people's chances of being exposed to and threatened by various radiations. Nuclear and radiation safety issues It has become increasingly prominent and has attracted much attention. Radiation protection materials and equipment are the key to ensuring the safety of workers in radiation sites and the public, and are also an effective means to resolve the crisis of nuclear accidents. They are an important guarantee for military and civilian radiation safety protection and are in urgent need. [0005] In recent years, lead has been widely used in the field of nuclear radiation...

AI Technical Summary

Problems solved by technology

Lead screens, lead plates, lead glass, etc. can also be applied to mobile protective bodies or places that need to provide temporary protection, but the risk of radiation leakage is high, the construction is difficult, the utilization rate is low, and the formability is poor

Flexible protective screens and protective clothing based on lead powder rubber have the advantages of strong removable and detachable properties and good airtightness, but low protection efficiency (small linear attenuation coefficient) and poor stability (matrix is ​​easy to age, lead powder Easy to fall off), low reuse rate (after multiple folds, the creases are damaged), high cost of use (to ensure the effectiveness of protection, it needs to be replaced frequently)
