含硼板PE板B4C中子吸收板

宁津县鸿宝化工有限公司新研制成功含硼聚乙烯板材，具有防中子辐射、防核辐射等产品，并获得国家专利，研究表明含硼防辐射聚乙烯板能够有效的防止核辐射及中子辐射给个人及社会造成的危害
含硼聚乙烯是一种相对廉价的中子屏蔽材料，对其中子屏蔽特性已进行过一维基准 实验。与其他中子屏蔽材料一样，该材料在中子的作用下产生γ射线。相对于屏蔽中子而言，γ射线是二级剂量。 而在含硼聚乙烯球中，主要是硼起吸收作用。硼对低能中子的反应截面比较大，在还没有发生氢的反应之前低能中子基本已被硼完全吸收，含硼聚乙烯在质量百分比为10﹪、厚度为15cm时，含硼聚乙烯对中子的屏蔽效果已达到要求。在此基础上再增加含硼量或者厚度，中子的积分泄露量基本不发生变化。 宁津鸿宝化工有限公司通过对本实验的终结论在对含硼聚乙烯的百分比与厚度上再次做了一系列的研发，具有抗辐照性能好，无活化产物，次级γ射线能量低；化学稳定性好，耐腐蚀，、无气味；机械强度高，表面光滑、便于去污、机械加工方便、易于安装维修的特点。
Ningjin Hongbao Chemical Co., Ltd. has recently developed boron containing polyethylene sheet, with high performance products, such as neutron radiation protection and nuclear radiation protection, and has obtained a national patent. The research shows that boron-containing radiation-proof polyethylene plate can effectively prevent the damage caused by nuclear radiation and neutron radiation to individuals and society. Boron-containing polyethylene is a relatively cheap neutron shielding material A one-dimensional benchmark experiment has been carried out on the subshielding characteristics. Like other neutron shielding materials, the material produces γ-rays under the action of neutrons. γ-rays are second-order doses relative to neutrons being shielded. Boron plays an important role in the absorption of boron-containing polyethylene balls. The reaction cross section of boron for low-energy neutrons is relatively large, and the low-energy neutrons have been completely absorbed by boron before the reaction of hydrogen has taken place. When the mass percentage of boron-containing polyethylene is 10% and the thickness of boron polyethylene is 15cm, The shielding effect of boron-containing polyethylene to neutron has reached the requirement. On this basis, the integral leakage of neutrons is basically unchanged by increasing boron content or thickness. Through the final conclusion of this experiment, Ningjin Hongbao Chemical Co., Ltd. has done a series of research and development on the percentage and thickness of boron containing polyethylene again. It has good radiation resistance, no activation products and low secondary γ -ray energy. Good chemical stability, corrosion resistance, Non-toxic, odorless, high mechanical strength, smooth surface, easy decontamination, easy machining, easy installation and maintenance.
