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

[0057] The embodiment of the present invention also provides a preparation method of the anti-ionizing radiation container, comprising:

[0058] S10, respectively providing the solution of the first resin system, the mixed solution of the second resin system and shielding filler, and the solution of the third resin system;

[0059] S20, loading the solution of the first resin system on the first fiber to obtain a first fiber prepreg, and loading the mixed solution of the second resin system and barrier filler on the second fiber to obtain a second fiber prepreg , and loading the solution of the third resin system on the third fiber to obtain the third fiber prepreg;

[0060] S30, laying up the first fiber prepreg on the bottom layer, then alternately stacking the second fiber prepreg and the metal layer 226 on the first fiber prepreg, and stacking the first fiber prepreg on the top layer Three-fiber prepreg, forming a preformed structure;

[0061] S40, performing curing and ...

Embodiment 1

[0097] (1) Surface modification of the metal layer 226: take a thin tungsten sheet with a thickness of 0.1 mm, and polish the surface of the tungsten sheet with sandpaper to improve its surface roughness. Place the polished tungsten sheet in a beaker filled with concentrated sulfuric acid for 30 minutes of acid etching, then rinse the surface of the tungsten sheet with clean water for 3 minutes, and dry it in an oven at 80°C for about 1 hour to obtain a surface-modified tungsten sheet.

[0098] (2) Surface modification of shielding filler: in parts by weight, take 100 parts of rare earth oxide, 100 parts of solvent and 5 parts of silane coupling agent, and the solvent is one of acetone and alcohol organic solvent or Several kinds; under normal temperature conditions, the above materials are uniformly mixed by mechanical stirring to obtain a shielding filler mixture; the shielding filler mixture is distilled under reduced pressure at 80°C to remove the solvent, and ball milled b...

Embodiment 2

[0105] Same as the steps of steps (1)-(3), (5)-(7) of Example 1, the difference is that step (4) is:

[0106] (4) Preparation of fiber prepreg: First, cut a plain basalt fiber fabric of a certain size, and apply the solution of the first resin system, the mixed solution of the second resin system and shielding filler, or the solution of the third resin system evenly on the On the fiber fabric, the fiber fabric is completely soaked to obtain the first fiber prepreg, the second fiber prepreg and the third fiber prepreg. Brush and squeeze the fiber fabric with a brush to make it evenly wet and expel air bubbles.

Abstract

The invention provides an anti-ionizing radiation container. The container includes an end cap and a container body, and the end cap is used for sealing the container body; and the container body includes a bottom wall and side walls fixedly connected with the bottom wall, the bottom wall and the side walls respectively comprise laminated plate bodies, each laminated plate body comprises an innerwall, a middle structure and an outer wall which are sequentially arranged from the interior to the exterior in an overlaid manner, the inner wall is a first fibrous resin material layer, the middle structure comprises second fibrous resin material layers and a metal layer alternately arranged from the interior to the exterior in an overlaid manner, and the outer wall is a third fibrous resin material 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 waste water accounts for a large proportion of radioactive waste, and radioactive waste liquid needs to be stored in storage tanks. In addition to meeting the general requirements, such storage tanks should also meet high radiation shielding requirements to protect operations. The safety of personnel and the normal operation of peripheral equipment. For the storage device of radioactive waste wat...
