摘要： A composite, neutron absorbing, coated article, suitable for installation in storage racks for spent nuclear fuel and for other neutron absorbing applications, includes a backing member, preferably of flexible material such as woven fiberglass cloth, a synthetic organic polymeric coating or a plurality of such coatings on the backing member, preferably of cured phenolic resin, such as phenol formaldehyde or trimethylolphenol formaldehyde and boron carbide particles held to the backing member by the cured coating or a plurality of such coatings. Also within the invention is a method for the manufacture of the neutron absorbing coated article and the use of such an article. In a preferred method the backing member is first coated on both sides thereof with a filling coating of thermosettable liquid phenolic resin, which is then partially cured to solid state, one side of the backing member is then coated with a mixture of thermosettable liquid resin and finely divided boron carbide particles and the resin is partially cured to solid state, the other side is coated with a similar mixture, larger boron carbide particles are applied to it and the resin is partially cured to solid state, such side of the article is coated with thermosettable liquid phenolic resin, the resin is partially cured to solid state and such resin, including previously applied partially cured resins, is cured to final cross-linked and permanently set form.
摘要翻译： 适用于安装在废核燃料和其他中子吸收应用的存储架中的复合中子吸收涂层制品包括背衬构件，优选为柔性材料，例如编织玻璃纤维布，合成有机聚合物涂层或多个 背衬构件上的这种涂层，优选固化的酚醛树脂，例如苯酚甲醛或三羟甲基酚甲醛，以及通过固化的涂层或多个这样的涂层保持在背衬构件上的碳化硼颗粒。 本发明还有一种制造中子吸收涂层制品的方法和这种制品的用途。 在优选的方法中，首先在其两侧涂覆有背衬构件的可热固的液体酚醛树脂的填充涂层，然后将其部分固化成固体状态，然后用热固性液体树脂和 精细分散的碳化硼颗粒和树脂部分固化成固体状态，另一侧涂覆有类似的混合物，较大的碳化硼颗粒被施加到树脂上并将树脂部分固化成固态，制品的这一面被涂覆 使用可热固的液体酚醛树脂，将树脂部分固化成固态，并将这种树脂（包括预先涂敷的部分固化的树脂）固化成最终交联和永久固定的形式。
