廠家直銷b4c含硼聚乙烯板-量大優(yōu)惠

B4C含硼聚乙烯板含硼量2——50%可按照客戶要求加工定制

聚乙烯抗輻射含硼板中,主要是硼起吸收作用。硼對低能中子的反應截面比較大,在還沒有發(fā)生氫的反應之前低能中子基本已被硼完全吸收,含硼聚乙烯在質量百分比為10﹪,厚度為15cm時,含硼聚乙烯對中子的屏蔽效果已達到要求。在此基礎上再增加含硼量或者厚度,中子的積分泄露量基本不發(fā)生變化.

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
