Basic features of B4C
Boron carbide (B4C) is an inorganic substance with a solid structure, generally made up of boron and carbon elements. Its excellent residential properties in numerous applications make it a vital practical material. The density of B4C has to do with 2.52 g/cm ³, which is lighter than other common protecting products. On top of that, the melting point of B4C is as high as 2450 ° C, allowing it to preserve great structure and performance in heat environments.
B4C has an extremely high neutron absorption cross-section, and its protecting result on fast neutrons is particularly significant. Neutrons are usually not bound by traditional products such as lead or light weight aluminum, and B4C can efficiently absorb neutrons and transform them into gamma rays, therefore reducing the harmful impacts of radiation. For that reason, B4C becomes an optimal selection for making neutron protecting materials.

The role of polyethylene
Polyethylene (PE) is a common polycarbonate that is commonly utilized in numerous areas because of its great optical, chemical and electrical insulation residential properties. In nuclear radiation security, integrating B4C with polyethylene can not just boost the toughness and use resistance of the product, yet additionally minimize the total weight of the product, making it easier to mount and apply.
When polyethylene shields neutrons, it slows them down by colliding with them. Although the neutron absorption capacity of polyethylene is much less than that of B4C, its deceleration and buffering residential or commercial properties can be completely used in the design of composite materials to improve the overall securing impact.
Preparation procedure of B4C polyethylene board
The process of producing B4C polyethylene composite panels includes multiple steps. Initially, high-purity B4C powder have to be prepared through high-temperature solid-phase synthesis. After that, the B4C powder is mixed with polyethylene resin in a specific percentage. During the blending process, B4C bits are uniformly distributed in the polyethylene matrix by using mechanical stirring and hot pushing.
After molding, annealing is executed. This process aids launch internal anxiety and boost the general efficiency of the material. Ultimately, the finished B4C polyethylene panels are cut right into the required specifications to facilitate succeeding building and usage.
