Production method of woven alloy lead fiber yarn chip safety shoes of nuclear radiation shielding products

Abstract

The invention discloses a production method of woven alloy lead fiber yarn chip safety shoes of nuclear radiation shielding products and relates to the technical field of nuclear radiation protection biological shielding. The production method disclosed by the invention comprises the following steps: adopting the shaped nuclear radiation shielding products, namely woven alloy lead fiber yearn chips as shoe cores, respectively sticking inner materials and upper surfaces on the inner side surfaces and the outer side surfaces of the shoe cores, drying, then sewing the upper surfaces with the inner materials, respectively coating anti-nuclear radiation glue serous fluid at the sewed parts and needle holes, clamping uppers after the anti-nuclear radiation glue serous fluid is fixed, and finally shaping the shoes. The products have the advantages of light weight, convenience in formation of shoe shapes, convenience in bending during walking of a user wearing the shoes and effect of being less prone to falling down.

Description

technical field [0001] The invention relates to the technical field of biological shielding for nuclear radiation protection. Background technique [0002] Studies have shown that the external radiation of nuclear power plants is mainly γ-rays, which mainly come from the fission products of nuclear reactions and the pipelines and valves activated by neutrons. Due to the appearance of activated corrosion products in the pipelines, radioactive particles in the pipelines are deposited, making the control area The environmental dose in many maintenance work places is relatively high, which increases the external exposure dose of the staff, which is generally relieved by shielding. Therefore, in the selection of shielding materials, strive to be efficient, safe, cheap and space-saving, usually steel, lead, ordinary concrete and heavy concrete are selected. The strength of steel is better, but the price is higher; concrete is cheaper than heavy metals, but the density is small, a...

Problems solved by technology

[0003] At present, the shielding products (such as lead shoes) used in the biological shielding system in the control area of ​​nuclear power plants in operation are mainly "solid metal block lead plates without gaps" rolled and formed in the clamps of normally made shoes. There are low lead equivalent, poor conformal performance, a lot of waste, and low resource utilization; t
