  • Patent number: 10881077
    Abstract: Compacting expanded perlite fines in the presence of a small amount of binder (starch and/or clay) and water, followed by drying, produces particles with low density, good integrity, and surprisingly higher absorption by volume than non-compacted expanded perlite or non-swelling clay. Furthermore, addition of a small amount of clumping agent (e.g., guar gum) to the compacted granules results in a clumping litter with low density, good integrity and comparable clumping ability to traditional clay clumping litter.

  • Patent number: 8075684
    Abstract: An aqueous liquid solution containing soluble salts of coloring metals—particularly manganese and ferric nitrate along with a sugar source and fulvic and/or humic acid can be readily applied to rock, soil or artificial construction surfaces impart a natural color tone to such surfaces. In this manner the visibility manmade disturbances is quickly and easily reduced and disturbed areas readily blend into the natural background. The liquid solution can be readily sprayed on rock or other surfaces. When the ambient temperature is warm natural color will develop in 4-8 days.

  • Patent number: 8029615
    Abstract: A pearlescent pigment includes a ceramic flake coated with a metal oxide. The metal oxide is, preferably, an oxide of titanium, iron, tin, chromium1, zirconium or a combination thereof, and the refractive index of the metal oxide coating is preferably at least 0.5 higher than that of the ceramic flake. The pearlescent pigment may be included in a coating applied to a metallic or plastic surface to give the surface a lustrous or pearlescent optical effect.

  • Patent number: 8025724
    Abstract: The invention provides a sulphur pellet comprising at least one H2S-suppressant, comprising in the range of from 60 to 100 wt % elemental sulphur, based on the total weight of the pellet. The invention further provides a process for the manufacture of sulphur pellets comprising at least one H2S-suppressant, comprising the steps of: (a) mixing elemental sulphur, one or more H2S-suppressants and optionally a filler in a mixing unit to obtain a mixture; (b) shaping and/or palletizing the mixture obtained in step (a) in a palletizing unit to obtain H2S-suppressant-comprising sulphur pellets. The invention further provides a process for the manufacture of a sulphur-comprising asphalt paving mixture comprising the steps of: (i) preheating bitumen at a temperature of between 140 and 180° C.; (ii) preheating aggregate at a temperature of between 140 and 180° C.

  • Patent number: 8024953
    Abstract: There is provided a lubricant for hot plastic working, which contains 20 to 40 mass % of iron oxide and 10 to 30 mass % of sodium silicate, wherein impurities are 3 mass % or less, and the lubricant contains 40 to 60 mass % of water. By virtue of combined action of these components, the lubricant exhibits excellent lubricity and suppliability and does not adversely affect the corrosion resistance of product. The lubricant is suitably used for lubricating a guide shoe in piercing-rolling, for example, a high-Cr steel and achieves a great effect of preventing a seizure flaw from occurring on the outer surface of product by being applied directly to the outer surface of a workpiece just before piercing rolling, preferably, within one second before starting piercing rolling.

  • Patent number: 8016935
    Abstract: An anticorrosion ferrite-based pigment, derived from a hydrometallurgical purification process of EAF dust. EAF dust is generated in an electric arc furnace for carbon steel production by processing scrap metal, direct reduced iron and/or pre-reduced hematite, and using CaO-rich slag; from a condensation reaction of metals vapors of Fe, or Zn and of Mn, Mg, Si and/or Al, and suspended CaO particles and oxygen. The pigment contains a non-toxic amount of lead, and includes condensed metal oxides, comprising ferrites MOFe2?3, M being Zn, Fe, Mn and Mg, and combinations thereof. The condensed oxides have ferrite structures preserved from the EAF dust, and form aggregates thereof. The pigment includes CaO entrapped by the ferrite structures and being partially available to react with humid air and/or water to protect the substrate against corrosion. The pigments are coated or uncoated. They are used for antifouling or paint formulations.
