  • Patent number: 10732330
    Abstract: The invention relates to high efficiency diffusion lighting coverings useful in LED lighting applications. The diffusing lighting coverings are made of organic diffusing particles homogeneously dispersed in a transparent polymer matrix. The primary organic diffusing particles are refractive index mis-matched to the matrix polymer. The refractive index contrast between the polymer matrix and diffusion particles, and particle size are selected to provide a high efficiency (minimized particle loading). The high efficiency diffusion coverings provides excellent light diffusion, high hiding properties and high light transmission. The secondary diffusion particles may optionally be added to further improve selected target properties of the covering. Nano-sized ZnO inorganic particles may also function as diffusion particles and optical brighteners as well UV stabilizers.

    Abstract: A dry ground calcium carbonate filler or additive made by dry grinding calcium carbonate in the presence of an organo-amine and then surface treating the ground calcium carbonate with a dispersant and the method of making the same is disclosed. Dry ground calcium carbonate filler or additive made by dry grinding calcium carbonate in the presence of an organo-amine such as triethanolamine and then surface treating the ground calcium carbonate with a dispersant such as sodium polyacrylate when added to a polyester polymer composition yields a lower viscosity of the polymer system than without the addition of triethanolamine followed by surface treating the ground calcium carbonate with a dispersant.

  • Publication number: 20150086769
    Abstract: A composite product includes gypsum in an amount of 60 to 90% by weight, fibers in an amount of 1.5 to 26% by weight substantially homogeneously distributed through the composite, and a rheology-modifying agent in an amount of 0.5 to 6% by weight. The composite is caused or allowed to cure to form a cured composite. The cured composite is a fire resistant component used in a fire-rated door core, a fire-rated door or a fire-rated building panel. The fire resistant component may include a building panel, a door panel, a door core, a door rail, a door stile, a door lock block, a door border, or a door insert.

  • Patent number: 8980982
    Abstract: A plastic packaging component is provided that is formed of a resin containing an electromagnetic spectrally detectable additive mixed with the resin. The resin formed into a plastic packaging component of an aerosol package lid, an aerosol spray button, an aerosol spray tube, a trigger sprayer, an integrated lid-sprayer, a grease cartridge, a grease cap, plastic fiber toweling, a packaging strap, a pail lid, a jar cap, or a brush. A process for detecting a displaced packaging component in an organic production stream is provided that includes adding to a resin an electromagnetically detectable additive intermixed with the resin and forming the additive loaded resin into the plastic packaging component. The production stream is then scanned for the detectable signal of the additive. Upon detecting the additive, an alarm signal is provided that the production stream contains the displaced packaging component.

  • Publication number: 20150051330
    Abstract: The present invention discloses a 3D printing powder produced by laying a gypsum powder; coating a water-soluble resin powder on the gypsum powder, and the water-soluble resin powder forming a colloid in water; pressing the water-soluble resin powder and the gypsum powder flatly to form a mixed layer; and adding water to the mixed layer. The mixed layer formed by using a water-soluble resin powder such as oxazoline resin, polyoxyethylene, or polyvinyl alcohol and pressing the water-soluble resin powder with the gypsum powder, so that the structural strength of 3D printing finished goods can be improved for several times, and the finished goods will not be deformed by external forces or smudged by colorants easily, and the finished goods can have smooth surfaces.
