1. Overview of neutron shielding materials.
Neutron shielding materials are materials that are capable of absorbing or attenuating neutron radiation. Since neutrons are not charged, common shielding materials such as lead and concrete cannot effectively shield neutrons, so special neutron shielding materials need to be selected. Common neutron shielding materials include boron-containing polyethylene sheets, boron-containing polypropylene sheets, boron-containing polyamide fibers, etc.
Second, the performance characteristics of boron-containing polyethylene board.
Boron-containing polyethylene board is a commonly used neutron shielding material, which has the characteristics of good neutron shielding effect, corrosion resistance, wear resistance, radiation protection and so on. The neutron shielding effect of boron-containing polyethylene sheets mainly comes from boron, which can absorb neutrons and attenuate neutron radiation. At the same time, boron-containing polyethylene sheets also have good mechanical properties and processability, which can meet the requirements of neutron shielding with various complex shapes.
3. Neutron shielding effect of boron-containing polyethylene plate.
The neutron shielding effect of boron-containing polyethylene sheets is mainly determined by the boron content in them. In general, the higher the boron content, the better the neutron shielding. Depending on the shielding requirements, the thickness and boron content of the boron-containing polyethylene sheet can be adjusted. In common neutron shielding projects, the neutron shielding effect of boron-containing polyethylene plate can reach n 05 requirements.
Fourth, the application range of boron-containing polyethylene board.
As a commonly used neutron shielding material, boron-containing polyethylene sheet is widely used in nuclear industry, nuclear medicine, scientific research and other fields. In the nuclear industry, boron-containing polyethylene sheets can be used for neutron shielding in reactors, nuclear fuel reprocessing plants, nuclear test sites, etc.;In nuclear medicine, boron-containing polyethylene sheets can be used for neutron shielding in medical accelerators, radioactive equipment, etcIn the field of scientific research, boron-containing polyethylene sheets can be used for neutron shielding in laboratories, such as neutron scattering experiments, neutron photography, etc.
5. Manufacturing process of boron-containing polyethylene board.
The manufacturing process of boron-containing polyethylene board mainly includes batching, mixing, pressing, curing, cutting and inspection. During the batching and mixing process, polyethylene and boron elements need to be homogeneously mixedIn the pressing process, the mixed raw materials need to be put into the mold for high temperature and high pressure molding;During the maturation process, the pressed material needs to be cooled and stabilizedDuring the cutting and inspection process, the matured material needs to be cut and inspected to ensure that its quality and performance meet the requirements.
6. Market prospect of boron-containing polyethylene board.
With the continuous development of the nuclear industry and nuclear medicine, the market demand for neutron shielding materials is also increasing. As a commonly used neutron shielding material, boron-containing polyethylene sheet has a wide range of application prospects. In the future, with the continuous progress of technology and the continuous expansion of application fields, the market demand for boron-containing polyethylene board will continue to increase, and its technical level and production capacity also need to be continuously improved.
