含硼聚乙烯是用于防中子、射线的高分子复合屏蔽材料,由于这种材料具有强度高、密度均匀、耐酸碱腐蚀、中子屏蔽性能优越的特点,因此,在中子屏蔽防护中应用广泛。Boron-containing polyethylene is a polymer composite shielding material for neutron and ray protection. Due to its high strength, uniform density, acid ...
Examples are given in which the ethylene polymer is polyethylene.
Natural polymer examples include cellulose, silk, wool, DNA, proteins, and latex from a rubber tree plant. Polyurethane, polyethylene, nylon, and vulcanized rubber are synthetic, or man-made, polymers. Polymers are formed by a process called polymerization, a chemical reaction in which molecules ...
