含硼聚乙烯防护中子辐射墙壁板拼接组成方案

含硼聚乙烯防护中子辐射墙壁板具有良好的工程性能、尺寸稳定性好，具有较满意的耐γ辐射性能，使用温度为80~100℃，屏蔽热中子、快中子和γ辐射性能明显优于聚乙烯，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。

Application field and market analysis:
It can be used for nuclear power plant spent fuel and nuclear experiment product tank, neutron beam collimator, neutron trapper, medical and health and other aspects as radiation shielding and absorption materials.
At present, China's nuclear power construction has entered the stage of large-scale construction from the initial stage, but on the whole, there are still some problems in China's nuclear power construction, such as small scale, low autonomy and so on. The planned installed capacity of nuclear power in China will increase from 1% to 4% of the total installed capacity of electric power. The construction of nuclear power station mainly adopts the combination of introducing foreign technology and independent construction, and there is a strong demand for the localization of auxiliary equipment and materials. The neutron absorption plate produced by our company has been used by domestic and foreign users for many years, and the use effect has proved that it can completely replace the imported products, which is of great value It has a good market prospect.

含硼聚乙烯防护中子辐射墙壁板中，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，含硼聚含硼聚乙烯防护中子辐射墙壁板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.
