  • Patent number: 10995033
    Abstract: Systems and methods according to present principles enhance aspects of applied plaster coats. In particular, the materials include a synthetic substitute aggregate (SSA), added to a cementitious base coat, for a plastering step prior to application of stucco or acrylic synthetic finishes or finish coats. The addition of SSA to a pre-blended cementitious base coat creates a light weight product which in some implementations is highly advantageous for the plastering industry.

  • Patent number: 10961695
    Abstract: A method for producing a sustainable building without the use of heavy equipment. Such a building may include an adjustable foundation to eliminate the need to flatten the building surface below. The frame may be constructed by using hand tools to assemble pre-rolled galvanized steel rods. A pre-cut perforated galvanized steel sheet can then be laid on the frame and sheathed with a pre-mixed mortar that may be created by mixing materials easily found in impoverished countries, such as natural lime, river sand, white clay, and fly ash. The roof may be layered with a thin solar film to allow for the incorporation of solar cells to harness solar energy and may further include a rainwater collection mechanism to allow for the roof to also collect clean rainwater.

    Abstract: A method of forming a material structure from structural units contained within a liquid solution in a spray head is described. The liquid solution includes a solvent and a solute, the solute comprising a plurality of the structural units, the structural units including monomer units, oligomer units, or combinations thereof. The method comprises forming droplets of the liquid solution including the structural units, and spraying the droplets on a substrate, thereby substantially increasing the reactivity of the structural units within the droplets relative to the structural units within the liquid solution in the spray head. The increase in reactivity can result from the droplets containing an excess of a particular ion, the ion excess resulting from a voltage applied to conductive walls of the device which dispenses the droplets. The material structure is then formed on the substrate from the more highly reactive structural units within the droplets.

  • Publication number: 20130064974
    Abstract: Methods and apparatuses for converting expanded polystyrene into a rigid material are disclosed herein. The methods of modifying EPS herein generally include placing EPS workload into a pressurized chamber and applying heat and pressure through a gas. The application of heat and pressure is held for a determined amount of time, the pressure of the internal chamber is then lowered below atmospheric pressure and a hot or cool step is administered. The resulting CPS product can be modified in a multiple number of ways depending on the desired end product.

  • Patent number: 8236865
    Abstract: A hydrophilic vinylidene fluoride resin composition, comprising: porous vinylidene fluoride polymer particles and a hydrophilic polymer having a weight-average molecular weight of at least 2×105 contained in the pores of the porous vinylidene fluoride polymer particles. The composition is preferably obtained by subjecting a slurry containing porous vinylidene fluoride polymer particles after suspension polymerization to an appropriate degree of heat treatment for adjusting the amount of residual polymerization initiator, then impregnating the Polymer particles with a hydrophilic monomer and polymerizing the monomer. The thus-obtained vinylidene fluoride resin composition exhibits persistent hydrophilicity and good processability.
