防中子辐射屏蔽**板 Y辐射聚乙烯板 防中子辐射屏蔽**板 Y辐射聚乙烯板中,主要是硼起吸收作用。硼对低能中子的反应截面比较大,在还没有发生氢的反应之前低能中子基本已被硼完全吸收,含硼聚乙烯在质量百分比为10%、厚度为15cm时,含硼聚乙烯对中子的屏蔽效果已达到要求。在此基础上再增加含硼量或者厚度,中子的积分泄露量基本不发生变化。 防中子辐射屏蔽**板 Y辐射聚乙烯板的主要优点:防中子辐射或是防核辐射,能够有效的防止核辐射给家庭及社会造成的危害、防辐射、在隔离辐射的同时具有聚乙烯板的的各种优点。 山东艾堡森较新研制成功含硼聚乙烯板材,具有防中子辐射、防核辐射等高性能产品,并获得国家**,研究表明含硼防辐射聚乙烯板能够有效的防止核辐射及中子辐射给个人及社会造成的危害,并具有以下特点: A、较高的耐磨性:由于其*特的分子结构,耐磨性**一般的金属塑料产品,是碳钢的6.6倍,不锈钢的5.5 倍,黄铜的27.3倍,尼龙的6倍,聚四氟的5倍。 B、不粘性:表面张力大磨擦系数小,无极性,所以与常见物质不亲和,因此不易粘 含碳化硼量:百分之十(以重量计) 密度:≥1.028g/cm3 密度差:≤0.01g/cm3 热变形温度(载荷ρ=0.46Mρa):72℃ 线膨胀系数:8.933×10-51/℃ 耐热温度:126℃(DTA测量值) 抗热强度:≈24MPa 冲击强度(缺口):≈19KJ/m2 Boron plays an important role in the Y radiation polyethylene plate, which is a special plate for neutron radiation shielding. The reaction cross section of boron to low-energy neutrons is relatively large. Before the reaction of hydrogen, low-energy neutrons have been completely absorbed by boron. When the mass percentage of boron containing polyethylene is 10% and the thickness is 15cm, the shielding effect of boron containing polyethylene to neutrons has reached the requirements. On this basis, with the increase of boron content or thickness, the integrated leakage of neutrons basically does not change. The main advantages of Y radiation polyethylene board for neutron radiation shielding: neutron radiation protection or nuclear radiation protection, which can effectively prevent the harm of nuclear radiation to the family and society, radiation protection, and has various advantages of polyethylene board at the same time of radiation isolation. Shandong aibaosen has successfully developed the latest boron containing polyethylene sheet, which has high-performance products such as neutron radiation protection and nuclear radiation protection, and has obtained the national patent. The research shows that the boron containing radiation protection polyethylene sheet can effectively prevent the harm of nuclear radiation and neutron radiation to individuals and society, and has the following characteristics: A. Extremely high wear resistance: due to its unique molecular structure, its wear resistance is higher than that of general metal plastic products, 6.6 times of carbon steel, 5.5 times of stainless steel, 27.3 times of brass, 6 times of nylon, 5 times of polytetrafluoroethylene. B. Non stick: large surface tension, small friction coefficient, non polarity, so it is not compatible with common substances, so it is not easy to stick Boron carbide content: 10% (by weight) Density: ≥ 1.028g/cm3 Density difference: ≤ 0.01g/cm3 Thermal deformation temperature (load ρ = 0.46M ρ a): 72 ℃ Linear expansion coefficient: 8.933 × 10-51 / ℃ Heat resistant temperature: 126 ℃ (DTA measurement value) Thermal strength: ≈ 24MPa Impact strength (notch): ≈ 19kj / m2
