Problems solved by technology

Traditional anti-ionizing radiation materials have many disadvantages: metals, heavy metals, and concrete all have the characteristics of high density and high quality, and poor mobility; for strong corrosive waste liquids and coastal working environments, metal materials are easily corroded, resulting in reduced performance and shortened lifespan ; High energy consumption in the manufacturing process, long manufacturing cycle, etc.
This can no longer meet the requirements of modern nuclear equipment and nuclear facilities for containers such as light weight, small size, environmental friendliness, and multi-function.

preparation example Construction

[0062] The embodiment of the present invention also provides a preparation method of the anti-ionizing radiation container, comprising:

[0063] S10, providing the solution of the resin system and the inner lining layer 210;

[0064] S20, loading the solution of the resin system on the fiber and the metal wire;

[0065] S30, winding the fiber loaded with the resin system solution and the metal wire on the outer surface of the inner liner 210 to form a preformed container body 200;

[0066] S40, performing curing treatment on the preformed container body 200 to form the container body 200; and

[0067] S50, assembling the container body 200 and the end cap 100.

[0068] In step S10, the solution of the resin system includes the resin system and a solvent, and the solvent may be an organic solvent such as ethanol, toluene, acetone, ethyl acetate, etc., preferably a highly volatile organic solvent. The solvent can be determined according to the type of the resin.

[0069] In ...

Embodiment 1

[0085] (1) Material preparation: 100 parts by weight of tetraglycidylamine epoxy resin (AG80) and 58 parts by weight of diaminodiphenylsulfone (DDS) curing agent were weighed. The curing agent is dissolved by adding a small amount of acetone, and the acetone solution of the dissolved curing agent is mixed with the tetraglycidylamine epoxy resin until the solution is uniform and clear to obtain a mixed solution of the resin and the curing agent. Take by weighing 16 parts by weight of micron-sized erbium oxide (Er 2 o 3 ) shielding filler (particle size 5-7μm), 15 parts by weight of acetone and 5 parts by weight of KH560 silane coupling agent, KH560 silane coupling agent is dissolved in acetone, then add erbium oxide shielding filler, at a temperature of 10 ° C ~ Stir evenly at 40°C and activate at a constant temperature to prepare a modified shielding filler solution. Mix the modified barrier filler solution with the mixed solution of resin and curing agent, and adjust the so...

Embodiment 2

[0093] The same as the steps of steps (1)-(2), (4)-(7) of Example 1, the difference is that step (3) is:

[0094] (3-1) Winding of the fiber layer 222: Make the fiber pass through the dipping tank 510 and the ultrasonic device 520 filled with the solution of the resin system prepared in step (1) at a certain pulling speed. The fiber bundles of pre-impregnated fibers are paralleled at the winding nozzle 540 after passing through the tension roller 530, and are wound on the alloy lining layer 210 according to the combination of spiral winding and hoop winding, and are wound layer by layer to the designed number of layers , to obtain the fiber layer 222 .

[0095] (3-2) Tungsten wire layer winding: passing through the dipping tank 510 and the ultrasonic device 520 filled with the solution of the resin system prepared in step (1). The fiber bundle of the prepreg tungsten wire passes through the tension roller 530 and is paralleled at the wire winding nozzle, and is wound on the a...

Abstract

The invention discloses an anti-ionizing radiation container, which comprises an end cap and a container body. The end cap is used for sealing the container body, the container body comprises a linerlayer and a fiber and metal wire composite layer wound on the outer surface of the liner layer, the fiber and metal wires are loaded with a resin system, and the fiber and metal wires cover the outersurface of the liner layer. The invention also discloses a preparation method of the anti-ionizing radiation container.

Description

technical field [0001] The invention relates to the field of nuclear power, in particular to an anti-ionizing radiation container and a preparation method thereof. Background technique [0002] In recent years, with the development of the nuclear power industry, the safe disposal of radioactive waste from nuclear power plants has become a matter of great concern to the public. Realizing radioactive waste reduction treatment, deep purification and safe disposal of radioactive effluent will bring huge economic, social and environmental benefits. For nuclear power plants, radioactive wastewater accounts for a large proportion of radioactive waste, and radioactive wastewater treatment using adsorption columns, membrane technology, etc. usually needs to be carried out in pressure vessels. This type of pressure vessel must not only meet the universality of pressure vessels In addition to the requirements, high radiation shielding requirements should be met to protect the safety o...
