Boron-containing polyethylene boards are specialized composite materials for neutron radiation shielding. They are made by mixing ultra-high-molecular-weight polyethylene with boron compounds, forming a composite shielding material with excellent radiation protection properties. This makes them a high-quality alternative to traditional shielding structures like concrete and lead.

Advantages:

In addition to their neutron radiation shielding function, boron-containing polyethylene boards retain the excellent physical and chemical properties of ultra-high-molecular-weight polyethylene:

1. Good low-temperature impact resistance: They maintain strong impact resistance even in low-temperature environments and are not prone to brittle fracture.
2. Wear resistance: Due to their unique polymer chain structure, pure ultra-high-molecular-weight polyethylene has better wear resistance than most metals and plastics.
3. Low friction and self-lubricating: The polymer chains have good self-lubricating characteristics, reducing motion resistance and saving energy.
4. Corrosion resistance: They can withstand corrosion from most acids, alkalis, and salts except strong oxidizers.
5. Anti-stick properties: The material has low surface tension and friction, so substances don’t easily stick to the board surface.

Applications:

Boron-containing polyethylene can be processed into shielding walls, equipment linings, protective modules, and shielding components, widely used in:

1. Transportation: Cabin walls and partitions in airplanes, trains, ships, etc.
2. Nuclear industry: Shielding walls for nuclear power plant control rooms, linings for spent fuel storage and transport containers, temporary nuclear waste storage, and radiation shielding maintenance for nuclear devices.
3. Medical field: BNCT (Boron Neutron Capture Therapy) treatment rooms, radioactive drug dispensing tables, radiation therapy auxiliary shielding structures.
4. Research facilities: Neutron physics labs, particle accelerator devices, neutron target stations, and small experimental reactors; provides shielding against various neutrons generated during device operation.
5. Industrial non-destructive testing: Casings for petroleum neutron logging equipment, neutron testing and imaging equipment shielding, and protective casings for nuclear instruments.
6. Special equipment: Lightweight neutron shielding for specialized devices; processed into shielding modules or protective boxes to achieve neutron radiation protection while keeping structural weight controlled.
