Problems solved by technology

Natural rubber, neoprene, butyl rubber and other rubber are mostly used as the main materials in the existing radiation protection gloves. Under the combined effects of organic solvents and other chemicals and radiation aging, the service life is often difficult to exceed 1 month, and some even 1 Lost value within a week and needs frequent replacement
Frequent replacement not only leads to an increase in direct use costs, but also a substantial increase in post-processing costs

Abstract

The invention provides a chemical-resistant multi-layer radiation-proof glove which is of a multi-layer structure and comprises at least one neutron protective layer, at least one X-ray and gamma-rayprotective layer and at least one polyvinyl alcohol layer, and the polyvinyl alcohol layer is a middle layer. The chemical-resistant multi-layer radiation-proof glove has excellent anti-radiation capability and radiation aging resistance, can effectively protect the radiation of X-rays, gamma-rays, neutrons, deuterium, tritium and the like, and can also effectively protect organic solvents and other chemicals, so that the service life of the radiation glove is greatly prolonged; therefore, the life health of nuclear industry employees can be better protected.

Description

technical field [0001] The invention belongs to the technical field of protective equipment, in particular to a chemical-resistant multilayer radiation-proof glove. Background technique [0002] In nuclear fuel reprocessing technology, chemical separation and purification methods are used to separate fissile plutonium isotopes, uranium, and precious metals from irradiated nuclear fuel. The chemical separation and extraction technologies often use tributyl phosphate, n-octylbenzene, etc. Organic solvents and chemicals such as N,N-diisobutylcarbamoylmethylphosphine oxide and malonamide. The radiation-proof gloves worn by workers during the processing process are required not only to have good radiation protection and radiation aging resistance, but also to have good resistance to chemicals such as organic solvents. Natural rubber, neoprene, butyl rubber and other rubber are mostly used as the main materials in the existing radiation protection gloves. Under the combined effec...
