Neutron Shielding Material--Boron-Containing Polyethylene--The Function and Main Properties of Boron-Containing Polyethylene Sheet

Polyethylene is a hydrocarbon containing a large number of hydrogen atoms, and the hydrogen content can reach 7. 92 × 10 22 atoms/cm 3

The polyethylene sheet itself does not have the effect of radiation protection. When boron is added during the processing of the polyethylene sheet, the processed sheet can be protected from radiation, which is called boron-containing polyethylene sheet. In the boron-containing polyethylene board, boron plays the main role of absorption. When the boron content is 10% and the thickness of the board is 15mm, the protective effect of the board on seeds has reached the requirements.

High temperature molding material of boron-containing polyethylene board, adding 3%-30% of boron carbide, customized according to your requirements

Regarding the thickness, the thickness of boron-containing polyethylene board is generally thick. The production process of polyethylene board is limited to 200MM, and sometimes the thickness of boron-containing board will reach 400MM or thicker. In order to prevent neutrons from penetrating neutrons, special splicing will be used. .

Boron-containing sheet Lead-boron polyethylene sheet application fields:

One, nuclear power plant wall panels. The effect of preventing neutron radiation and nuclear radiation has proved that it can completely replace imported products.

Second, it can be used as the cover plate of the radioactive source library, because it has an effect on radioactive substances such as neutrons and gamma rays.

Third, the pads, support blocks, etc. of drilling platforms and radiation shields in nuclear engineering construction.
