厂家直销b4c含硼聚乙烯板-量大优惠

B4C含硼聚乙烯板含硼量2——50%可按照客户要求加工定制

聚乙烯抗辐射含硼板中,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.

Boron plays an important role in the absorption of radiation-resistant board of polyethylene. The reaction cross section of boron to low energy neutrons is relatively large. Before hydrogen reaction, low energy neutrons have been completely absorbed by boron. When the mass percentage of boron containing polyethylene is 10% and the thickness is 15cm, the shielding effect of boron containing polyethylene to neutrons has reached the requirements
