Fat, Fatty Oil, Fatty Oil Acid Or Salt Thereof Containing Patents (Class 106/38.24)
  • Patent number: 8882898
    Abstract: The present invention is directed to an emulsified release agent for use in manufacturing of wood products from wood fibers or chips with pMDI adhesives, where the application process for the release agent would normally agitate the release agent. The emulsified release agent is simple to manufacture, has good stability and storage, provides effective release between the wood product and the metal surfaces, allows for production of wood products from wood fibers or chips at high temperature, without causing excessive press buildup and improves the physical properties of the wood product and shortens press time. The emulsified release agent composition for use with a pMDI adhesive comprises an emulsified mixture of: (a) an alkali metal salt of a fatty acid having 8-18 carbon atoms, and (b) an alkali metal salt of a phosphate ester having 6-22 carbon atoms and having an HLB number of 4 or less.

  • Publication number: 20140224444
    Abstract: The present invention provides processes for die casting metals which are more energy efficient and less expensive than the current metal die casting processes. The die casting processes discussed herein utilize a water-soluble die release fluid and hydraulic equipment which uses water-insoluble hydraulic fluid. By doing so, the hydraulic fluid and die release fluid present in the waste collected from the die casting process can be collected via separation techniques. One or both of the collected hydraulic fluid and die release fluid may then be re-used in the same die casting process, another die casting process, or another processes altogether.

  • Patent number: 7273086
    Abstract: In a lubricant composition suitable for use in the manufacture of aluminum alloys comprising lubricant base selected from the group consisting of solid lubricants, liquid lubricants, grease lubricants, emulsion lubricants, and dispersion lubricants, the improvement wherein the lubricant composition further comprises: an effective amount of water and surfactant. It is believed that mixing oil with water and surfactant provides a method for uniformly distributing the surface oxide at the meniscus for casting applications. Uniform distribution of the oxide at the meniscus reduces vertical fold formation that can lead to cracks in the aluminum ingot. In addition, the mixture promotes uniform heat transfer around the mold. Uniform heat transfer around the mold allows the solidifying aluminum alloy to stay in contact with the mold longer and form stronger ingot shells. A process for continuous or semi-continuous casting of aluminum alloys via the use of this lubricant composition is also disclosed.
