高密度聚乙烯中子屏蔽材料工廠介紹

High-density polyethylene neutron shielding material

高密度聚乙烯中子屏蔽材料采用的是高溫模壓工藝，高密度聚乙烯不僅可有效慢化快中子,同時又是良好的中子屏蔽材料，當快中子與屏蔽體中氫原子核發生彈性碰撞時,最容易將其能量傳遞給氫原子核而損失能量,從而將快中子慢化為慢中子和熱中子。所以,普通聚乙烯是屏蔽快中子最好的慢化劑。 

High-density polyethylene neutron shielding materialis a product specially designed for nuclear and radiation shielding applications, its neutron shield properties have been tested and certified.As same as other shielding materials ,this material can produce Y-ray under the action of neutron, and Y-ray dose is second grade relative to shielding neutron.Borated polyethylene costs low and light-weight-ed,so it is the best material to replace lead to shield neutron.The boron content is from 2% to 20% by weight according to applications and customer's requirements.

     高密度聚乙烯中子屏蔽材料主要用于防護中子及γ射線，具有抗輻射性能好，無活化產物，次級γ射線能量低，機械性能高，耐腐蝕，無毒無味，抗沖擊，耐低溫和化學穩定性。聚乙烯、含硼聚乙烯板主要用于各大核電站 、核反應堆、中石油、軍隊、中科院、研究室、醫院及核實驗用產品罐、中子束準直器、中子捕集器以及核反應堆的控制棒材料及核屏蔽材料等研究領域。作為屏蔽中子，射線，輻射屏蔽吸收的材料。
