高密度聚乙烯中子屏蔽材料工厂介绍

High-density polyethylene neutron shielding material

高密度聚乙烯中子屏蔽材料采用的是高温模压工艺，高密度聚乙烯不仅可有效慢化快中子,同时又是良好的中子屏蔽材料，当快中子与屏蔽体中氢原子核发生弹性碰撞时,最容易将其能量传递给氢原子核而损失能量,从而将快中子慢化为慢中子和热中子。所以,普通聚乙烯是屏蔽快中子最好的慢化剂。 

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护中子及γ射线，具有抗辐射性能好，无活化产物，次级γ射线能量低，机械性能高，耐腐蚀，无毒无味，抗冲击，耐低温和化学稳定性。聚乙烯、含硼聚乙烯板主要用于各大核电站 、核反应堆、中石油、军队、中科院、研究室、医院及核实验用产品罐、中子束准直器、中子捕集器以及核反应堆的控制棒材料及核屏蔽材料等研究领域。作为屏蔽中子，射线，辐射屏蔽吸收的材料。
