    Abstract: The method is for treating a marine object. A composition is provided that has an organic substance. The composition is applied to the marine object. The composition has a first layer and a second layer. A first organic substance on the first layer attracts bacteria. The bacteria consume the first organic substance and during this process use oxygen. The bacteria thus reduce an oxygen level in a boundary layer adjacent to a surface of the marine object. The first layer of the composition erodes to expose the second layer. The bacteria consume a second organic substance of the second layer.

  • Publication number: 20110033613
    Abstract: A method and composition are disclosed that provide protection of refractory materials used, e.g., in kiln and slagging coal-gasifier operations. Inert high-temperature melting crystalline compounds and glasses are used to fill defects on the surface and/or interior of the refractory material. At the operation temperatures, the inert crystalline compound mixes with slag and increases the viscosity and melting point temperature, reducing the ability of the slag to penetrate into the refractory, which minimizes breakdown of the refractory material. The same scheme can potentially be applied to sealing of geological formations, e.g., for CO2 sequestration, and repairing of engineering materials currently in service while continuing to operate in aggressive environments.

  • Patent number: 7782994
    Abstract: This invention relates to an inhibitor of lead-induced stress corrosion cracking including nickel boride in the secondary side of steam generator tubes in nuclear power plants and an inhibition method using the same, and more particularly, to an inhibitor of lead-induced stress corrosion cracking, in which nickel boride is added to secondary side cooling water of the steam generator in an amount of 0.2˜6 g/l, and to an inhibition method using the same. According to this invention, when the inhibitor of lead-induced stress corrosion cracking is added to the secondary side of the steam generator tube in nuclear power plants, stress corrosion cracking of the tubes, which occurs in the lead-containing neutral or caustic solution, and a crack growth rate are decreased, thus increasing elongation. Further, a stress corrosion cracking ratio is decreased, and therefore the stress corrosion cracking resistance of metal or alloy can be improved.

    Abstract: The invention concerns the use of cerium dioxide, especially in the form of discrete cerium dioxide particles with particle sizes in the range from 0.005 to 150 ?m, as inorganic radical trap to stabilize organic polymers, especially in the form of polymer-based formulations, varnishes, paints, coating compounds, or the like, against their photochemically, thermally, physically and/or chemically induced degradation by free radicals, especially against the effect of UV, advantageously in an optional combination with at least one UV-absorber and/or at least one additional radical trap. The radical-induced degradation of the organic polymers is effectively prevented by the use of cerium dioxide without the cerium dioxide itself becoming degraded. If a combination of cerium dioxide with an additional UV-absorber or radical trap is used, its effectiveness is extended through the presence of the cerium dioxide.

  • Patent number: 7459102
    Abstract: A corrosion inhibitor that includes several oxo-anion compositions useful for preventing the propagation of pit corrosion on aluminum and aluminum alloys. The oxo-anion compositions may include soluble polymeric oxidic acids comprising combinations of molybdenum, phosphorous, tungsten, and silicon. These compositions are useful as corrosion inhibitors in high-moisture, corrosive environments, such as radiators and cooling systems. For low-moisture environments, these oxo-anion compositions can be reacted with a counter-ion, such as various metals, including, but not limited to the rear earth metals, to form a soluble salt. The salt can then be adsorbed onto a carrier, such as paint pigments, which can then be applied to the surfaces of aluminum and aluminum alloys. These surface adsorbates then become sparingly soluble and are gradually released over time in the presence of an aqueous corrosive agent so as to prevent propagation of pit corrosion.

  • Patent number: 7247658
    Abstract: Surprisingly effective additive formulations for the reduction of highly undesirable yellowing or other discoloration of white, uncolored, polyurethane foam articles are provided. White polyurethane foam exhibits a susceptibility to yellowing and discoloration to a great extent, particularly in relatively short periods of time, than other types of polymeric articles. The inventive additives impart excellent low-discoloration properties over appreciable amounts of time of regular exposure to harmful elements, thereby according the pertinent industry a manner of providing white polyurethane foams for longer periods of time. Methods of producing such reliably white-colored polyurethane foams are also provided.
