Borated UHMWPE Neutron Shielding :

The boron-containing polyethylene plate produced by our company is mainly used in the fields of nuclear power plants, nuclear reactors, CNPC, military, Chinese Academy of Sciences, research laboratories, hospitals and nuclear test products cans, neutron beam collimators, neutron traps and nuclear reactors Control rod material and nuclear shielding materials research fields. As a shielding neutron, radiation, radiation shielding material absorption.

We can according to customer requirements to add boron carbide boron trioxide borax and lead content of 5% -50% can be customized production, and can be processed according to customer requirements or drawings Finished sheet thickness is 350mm More than 350mm we can design splicing Program

Produced by boron-containing ultra-high molecular weight polyethylene plate it has good anti-radiation properties, no activation products, secondary γ-ray energy is low; chemical stability, corrosion resistance, non-toxic, odorless; high mechanical strength, , Easy to decontamination, easy machining, easy to install and maintain the characteristics of neutrons integral leakage basically does not change.

Ultra-high molecular weight polyethylene is a very high wear resistance, creep resistance, self-lubricating, anti-stamping ability, light weight, the
Materials in the wear-resistant, load-bearing, energy absorption, anti-aging, shock absorption and a mold and so on than the PTFE skateboard more superiority. this

Description

Boron-containing polyethylene board BPE sheet is a good neutron protection material to replace paraffin and borax. It is made by mixing boron-containing board and boron carbide powder in high molecular polyethylene materials through high-speed stirring, kneading, plasticizing, and hot pressing. A new type of composite protective material.

The boron-containing polyethylene plates BPE sheet has high-performance products such as anti-neutron radiation and nuclear radiation protection. Research shows that the boron-containing radiation-proof polyethylene sheet can prevent the harm caused by nuclear radiation and neutron radiation to individuals and society. It can be processed in conventional special shapes.

In boron-containing polyethylene, 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 mass percentage of boron-containing polyethylene is 10% and the thickness is 15cm, the boron-containing polyethylene pairs The protective effect of neutrons has reached the requirements.

Application areas:

The boron-containing polyethylene sheets produced by our company are mainly used in major nuclear power plants, nuclear reactors, China National Petroleum Corporation, Chinese Academy of Sciences, research laboratories, nuclear experiment product tanks, neutron beam collimators, neutron traps, and control rod materials for nuclear reactors. Research fields such as nuclear protection materials. As a material that protects against neutrons, rays, and radiation absorption.
