  • Patent number: 8440747
    Abstract: Cold-pressed mats of lignocellulosic material having a Push Off Test extension equal to at least 85% of that of a mat made with a urea-formaldehyde resin are produced from a lignocellulosic material and binder system. These mats are produced at ambient temperature by separately adding each component of the binder system to the lignocellulosic material, blending the lignocellulosic material and binder system to coat the lignocellulosic material with the binder system, forming the coated lignocellulosic material into the desired form and applying pressure to the formed lignocellulosic material to obtain the desired thickness. The binder system includes: (i) at least one polyfunctional isocyanate and (ii) at least one aqueous dispersion of an adhesive or tackifier.

  • Patent number: 8410194
    Abstract: The biopolymer additive, in combination with water, functions as a soil conditioner that affects soil erosion and water infiltration. The biopolymer additive is derived from complex galactomannon-rich succulent plants. The succulent-derived (biopolymer) additive (SDA) may be used alone or in combination with polymers and copolymers of polyacrylamide (PAM). The combination of the SDA and PAM has a synergistic effect so that the resulting composition yields unexpected results and is a more effective treatment than either SDA or the PAM alone.

  • Publication number: 20130072600
    Abstract: A fire retardant molding contains a thermoplastic compound and an inorganic flameproof agent that is mixed with the thermoplastic compound and which acts by separating from water, having a proportion in the range of 10 wt % to 90 wt %. The fire retardant molding is produced by mixing the thermoplastic material with an inorganic flame-proofing agent, the flame-proofing agent having a proportion in the range of 20 wt % to 80 wt %, and by outputting the compound obtained by mixing, in particular as a flat product. The fire retardant molding is advantageously used, for example, in or on land-based vehicles, water-based vehicles, aircraft and buildings.

  • Publication number: 20130065053
    Abstract: Disclosed are composite pellets for extrusion molding wherein fusion does not occur between the pellets, and there is no variation in size and density. A molten material obtained by an extruder for a raw material containing a thermoplastic resin and wood powder is extruded into a strand shape through a die nozzle of the extruder, and cut into a predetermined length to form a pellet. At this time, the extrusion amount, the diameter of each nozzle hole, and the number of nozzle holes are adjusted so that the linear velocity (?d) of the molten material in each nozzle hole of the die nozzle is in the range of 12 to 50 cm/sec. Further, regardless of the variations in particle diameter, etc., a stable amount of the composite pellets are supplied to the extruder, and smoothly introduced to a screw of the extruder. The composite pellets and 12-hydroxystearic acid containing a metal of Ca, Mg, or Zn are agitated together, and 0.03 to 0.

  • Patent number: 8349919
    Abstract: A dry mixture for use with water has been developed to be used as an erosion control spray matrix for reducing erosion of sandy soils while awaiting development of a root system of plants to hold the soil in place. The dry erosion control mixture includes alpha-calcined calcium sulfate hemihydrate, a non-gypsum binder polymer; biodegradable fibers; and wood fiber mulch. An erosion control slurry is applied to an area of soil in need of erosion-control. After obtaining the dry erosion control mixture, it is mixed with water to form erosion control slurry. The ratio of the composition to the water is preferably from about 1:8 to about 1:12. Seed is distributed over the soil and the erosion control slurry is applied over the distributed seed.
