Basic qualities of B4C

Boron carbide (B4C) is a not natural substance with a solid structure, primarily made up of boron and carbon aspects. Its outstanding homes in numerous applications make it a crucial functional product. The density of B4C is about 2.52 g/cm ³, which is lighter than other usual shielding products. Additionally, the melting point of B4C is as high as 2450 ° C, allowing it to maintain good framework and efficiency in high temperature settings.

B4C has an extremely high neutron absorption cross-section, and its securing effect on rapid neutrons is especially substantial. Neutrons are normally not bound by conventional materials such as lead or aluminum, and B4C can successfully take in neutrons and convert them right into gamma rays, consequently minimizing the hazardous results of radiation. Therefore, B4C ends up being an optimal choice for producing neutron shielding materials.

The function of polyethylene

Polyethylene (PE) is a common thermoplastic that is widely used in different fields as a result of its excellent optical, chemical and electrical insulation properties. In nuclear radiation security, integrating B4C with polyethylene can not just enhance the strength and put on resistance of the material, however additionally decrease the overall weight of the product, making it less complicated to set up and apply.

When polyethylene shields neutrons, it slows them down by ramming them. Although the neutron absorption ability of polyethylene is much less than that of B4C, its slowdown and buffering buildings can be totally made use of in the layout of composite materials to improve the total protecting impact.

Preparation process of B4C polyethylene board

The process of making B4C polyethylene composite panels includes several steps. First, high-purity B4C powder should be prepared with high-temperature solid-phase synthesis. After that, the B4C powder is blended with polyethylene resin in a specific proportion. Throughout the mixing process, B4C bits are evenly distributed in the polyethylene matrix by utilizing mechanical stirring and hot pushing.

After molding, annealing is executed. This process helps release internal stress and improve the overall performance of the material. Ultimately, the finished B4C polyethylene panels are reduced into the needed specs to facilitate subsequent construction and use.
