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.

Excellent features of { crane outrigger pads , high molecular polyethylene outrigger pads } 1. The wear resistance ranks first in plastics, 4 times higher than nylon 66 and PTFE, and 6 times higher than carbon steel; 2. The impact strength ranks first among plastics, which is 2 times that of PC and 5 times that of ABS, and can maintain high toughness at liquid nitrogen temperature (-196 ℃); 3. The self-lubricating property is equivalent to that of PTFE, and the friction coefficient is only 0.07-0.11; 4. The shock energy absorption value is high among all plastics, and the noise reduction effect is very good; 5. It has high chemical stability and can withstand various corrosive media within a certain temperature and concentration range Ultra-high molecular weight polyethylene outrigger pads and anti-skid pads solve the shortcomings of high cost, non-wear resistance, heavy weight and short life of the previous wooden and steel pads, and are deeply loved and favored by the majority...
