    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.

  • Publication number: 20110067602
    Abstract: A simple and easily useable system for reverting an uncured colored concrete material back to a gray color, by merely determining the original pigment and loading initially used to color the concrete material. The system utilizes a collection of pigment mixtures that can be selected and combined as needed to revert virtually any colored concrete back to a gray color, thus eliminating or reducing the expulsion of non-gray or colored concrete and/or dirty rinse water. Additionally, the volume of rinse water needed to clean out gray concrete is significantly less than that needed to clean out colored concrete.
