Anti-radiation shielding uhmwpe board , anti-neutron shielding material manufacturer, production and processing, radiation room, research room, shielding wall.
Boron-containing ultra-high molecular weight polyethylene board is a new type of composite shielding material that is made by stirring boron carbide powder in high molecular polyethylene materials through high-speed stirring, kneading, plasticizing, and hot pressing. It has a good ability to weaken fast neutrons. Boron absorbs thermal neutrons and lead is particularly effective in shielding radiation. Therefore, the carbon anti-radiation boron carbide polyethylene plate anti-neutron shielding plate has the ability to shield fast neutrons, thermal neutrons and radiation. The comprehensive shielding effect of the boron-containing polyethylene board is helpful to simplify the shielding structure, can reduce the weight of the shielding body, and reduce the volume of the shielding body.
In the boron-containing ultra-high molecular weight polyethylene board , boron is mainly used for absorption. The reaction cross-section of boron to low-energy neutrons is relatively large. The low-energy neutrons are basically completely absorbed by boron before the hydrogen reaction occurs. When the boron-containing polyethylene has a mass percentage of 10 and a thickness of 15 cm, the boron-containing polyethylene is centered The shielding effect of the child has reached the requirement. On this basis, if the boron content or thickness is increased, the integral leakage of neutrons will basically not change. The technical indicators of the product are:
