1. Definition of Boron containing Ultra High Molecular weight Polyethylene (UHMWPE): Boron-containing ultra-high molecular weight polyethylene (UHMWPE) is a new type of composite neutron absorption material, which is composed of boron carbide powder and lead powder uniformly stirred through high speed stirring, kneading, plasticizing and hot pressing. It is a new type of hard neutron absorbing material developed by China Institute of Engineering Physics. It has been used for neutron and γ -ray protection in scientific research and nuclear engineering construction. The physical and chemical properties, radiation resistance and neutron absorption effect of the product have been fully studied and have independent intellectual property rights. 2. Advantages of boron-containing polyethylene panels: Polyethylene is a hydrocarbon with high hydrogen content and good ability to attenuate fast neutrons. Boron absorbs thermal neutrons, and lead absorbs neutrons from γ radiation. Therefore, lead-boron polyethylene plates have fast neutron absorption. The comprehensive neutron absorption effect of thermal neutron and γ radiation. The popularization and application of boron-containing polyethylene plate is helpful to simplify the neutron absorption structure, to reduce the weight of neutron absorption screen and to reduce the absorbed neutron volume. The boron polyethylene plate has good engineering properties, good dimensional stability and satisfactory γ radiation resistance. The performance of absorbing thermal neutron, fast neutron and γ radiation is obviously superior to that of polyethylene when the temperature is 80 ~ 100 ℃. The results show that the boron-containing radiation-proof polyethylene plate can prevent the harm caused by nuclear radiation and neutron radiation to individuals and society. 3. Application domain and market analysis Used as spent fuel for nuclear power plant and nuclear test tank, neutron beam collimator, neutron trap.
1.含硼超高分子量聚乙烯板的定義： 含硼超高分子量聚乙烯板是將碳化硼粉和鉛粉均勻地攪拌在高分子聚乙烯材料當中通過高速攪拌、捏合、塑化、熱壓而成的，是一種新型的復合吸收中子的材料。 它是中國工程物理研究院開發的一類新型硬質吸收中子的材料，已用于科研、核工程建設的中子及γ射線防護。該產品的理化性能和抗輻照性能及吸收中子效應作了充分的實驗研究，具有自主的知識產權。 2.含硼聚乙烯板的優點： 聚乙烯是碳氫化合物，含氫量高，對快中子有良好的減弱能力，硼吸收熱中子、鉛對γ輻射的吸收中子特別效果，因此，鉛硼聚乙烯板具有吸收快中子，熱中子和γ輻射的綜合吸收中子的效果，含硼聚乙烯板的推廣應用有助于吸收中子結構的簡化，能夠減輕屏吸收中子的重量，縮小吸收中子體積。 含硼聚乙烯板具有良好的工程性能、尺寸穩定性好，具有較滿意的耐γ輻射性能，使用溫度為80~100℃，吸收熱中子、快中子和γ輻射性能明顯優于聚乙烯，研究表明含硼防輻射聚乙烯板能夠防止核輻射及中子輻射給個人及社會造成的危害。 3.應用領域及市場分析： 用作核電站乏燃料及核實驗用產品罐、中子束準直器、中子捕集器。      |
