医用含硼聚乙烯A含硼防辐射屏蔽材料A防中子屏蔽板

含硼聚乙烯是一种高效的防中子屏蔽材料，将碳化硼粉和铅粉均匀的搅拌在超高分子量聚乙烯（UHMWPE）材料中，通过高速搅拌、捏合、塑化、热压而成。硼是一种微合金元素，有吸收中子的作用，聚乙烯是碳氢化合物，含氢量高，对快中子有良好的慢化作用。

Boron-containing polyethylene is an efficient neutron shielding material. Boron carbide powder and lead powder are uniformly stirred in ultra-high molecular weight polyethylene (UHMWPE) material, which is made by high-speed stirring, kneading, plasticizing and hot pressing. Boron is a microalloy element, which can absorb neutrons. Polyethylene is a hydrocarbon with high hydrogen content, which has a good moderating effect on fast neutrons.
