Product Description
Product Description
distinguishing feature
Boron carbide (chemical formula B4C) is an extremely hard ceramic material with a Mohs hardness of 9.3 which can absorb a large number of neutrons without forming any radioisotopes, so it is ideal for neutrons in nuclear power plants Absorber, the role of lead is particularly effective in shielding gamma radiation. In the ultra-high molecular weight polyethylene radiation-resistant lead-boron board, on the one hand, due to the shielding effect of lead on gamma radiation, the reaction cross section of boron to low-energy neutrons is relatively large. , the low-energy neutrons have been basically completely absorbed by boron before the hydrogen reaction has occurred; on the other hand, ultra-high molecular weight polyethylene is a hydrocarbon with a high hydrogen content and has a good ability to weaken fast neutrons. Can effectively absorb radiation energy. Therefore, adding lead and boron components to UHMWPE has a comprehensive shielding effect of shielding fast neutrons, thermal neutrons and gamma radiation.●Technical indicators Radiation-resistant lead-boron polyethylene board product technical indicators |
