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 mobility, detachability, and good airtightness, but low protection efficiency (small linear attenuation coefficient) and poor stability (matrix is ​​easy to age, lead powder is easy to Falling 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)
Radiation protection products based on metal fiber filaments with radiation protection functions will overcome the above-mentioned shortcomings, but related products are rarely seen

Embodiment 1

[0011] Example 1 : Lead-based alloy fiber wire with a diameter of 0.4mm is used as the inner core, carbon fiber is selected as the cladding layer, and the lead-based alloy fiber / carbon fiber composite fiber wire is obtained through core-clad weaving. On the loom, the composite fiber filaments are woven to form nuclear radiation protection fabrics.

[0012] The radiation protection performance of the fabric was tested on the NaI spectrometer, and the radioactive source was Cs-137. After testing, the radiation protection ratio is -5.8%.

Embodiment 2

[0013] Example 2 : The lead-based alloy fiber wire with a diameter of 0.3mm is used as the inner core, the polyamide fiber is selected as the cladding layer, and the lead-based alloy fiber / polyamide fiber composite fiber wire is obtained through core-wrapping weaving. Tungsten alloy fiber wire with a diameter of 0.3mm is used as the inner core, high-density polyethylene is selected as the cladding layer, and tungsten alloy fiber / high-density polyethylene fiber composite fiber wire is obtained through core-spun weaving. Using lead-based alloy fiber / carbon fiber composite fiber as the warp and tungsten alloy fiber / high-density polyethylene fiber as the weft, the composite fiber is woven on a loom to form a nuclear radiation protection fabric.

[0014] The radiation protection performance of the fabric was tested on the NaI spectrometer, and the radioactive source was Cs-137. After testing, the radiation protection ratio is -5.1%.

Embodiment 3

[0015] Example 3 : take the lead-based alloy fiber wire with a diameter of 0.3mm as the inner core, select polyester fiber as the covering layer, and weave through the core to obtain the lead-based alloy fiber / polyester fiber composite fiber wire. On the loom, the composite fiber filaments are woven to form nuclear radiation protection fabrics.

[0016] The three-layer fabric is superimposed and composited at a cross angle of 60° to form a three-layer nuclear radiation protection fabric. The radiation protection performance of the superimposed three-layer fabric was tested on the NaI spectrometer, and the radioactive source was Cs-137. After testing, the radiation protection ratio is -10.8%.

Abstract

A nuclear radiation protection fabric relates to the technical field of nuclear radiation protection. The nuclear radiation protection fabric comprises a woven fabric formed by weaving composite cello silks with a nuclear radiation protection function. The composite cello silks with the nuclear radiation protection function comprise metal filaments inner cores with the nuclear radiation protection function, and at least one layer of coating layer with a reticular structure is weaved outside the metal filaments inner cores. The nuclear radiation protection fabric has an excellent radiation protection performance, good flexibilityand gas permeability and is very comfortable, can be wildly used as daily radiation protection and nuclear emergency protection in the fields of nuclear power stations, hospitals, military nuclear equipments and the like.

Description

technical field [0001] The invention relates to the technical field of nuclear radiation protection, in particular to a nuclear radiation protection fabric. Background technique [0002] 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 has become increasingly prominent and has received 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. [0003] my country has accumulated certain technology and experience in traditional radiation protection materials, ...
