Boron-containing ultra-high molecular weight polyethylene polyethylene board is made by mixing boron carbide powder and
lead powder
evenly in A new type of composite shielding material is made of high-molecular polyethylene materials through high-speed stirring, kneading, plasticizing, and
hot pressing
.
Advantages of boron-containing polyethylene boards
Polyethylene is a hydrocarbon with high hydrogen content and good ability to attenuate fast neutrons. Boron
absorbs
thermal neutrons and lead. The shielding of radiation is particularly effective, so the lead-boron polyethylene board has a comprehensive shielding effect of shielding fast neutrons, thermal neutrons and radiation. The popularization and application of boron-containing polyethylene boards help to simplify the shielding structure and reduce the weight of the shielding body. volume.
The boron-containing polyethylene board has good engineering properties, good dimensional stability, and relatively satisfactory radiation resistance. The operating temperature is ~℃. The shielding performance of thermal neutrons, fast neutrons, and radiation is significantly better than that of polyethylene. Research shows that polyethylene containing Boron radiation-proof polyethylene boards can effectively prevent the harm caused by nuclear radiation and neutron radiation to individuals and society.
