A method of making a foamed glass body, including preparing an admixture of powdered glass, at least one carbonate based foaming agent, and at least devitrification inhibitor, heating the admixture to a first temperature to soften the glass, heating the admixture to a second, higher temperature to foam the softened glass into a foamed glass body, and cooling the foamed glass body, wherein the temperature of the foamed glass body always remains too cold for silica crystal growth. The crystal silica content of the so-formed foamed glass body is less than 1 weight percent.

Method of reducing the occurrence of crystalline silica in foamed glass by the introduction of chemical additives

Inorganic polymers are produced from silicate (&#x2014;Si&#x2014;O&#x2014;) and/or phosphonate (&#x2014;P&#x2014;O&#x2014;) bonds, commonly found in rocks and glass, to create new polymeric materials for rubbers, fibers, and plastics. These inorganic polymers have various advantages over organic counterparts including abundance on the earth's crust, and properties including nonflammability, low toxicity, recyclability, and excellent thermal and chemical resistance.

Inorganic ionomers made from minerals

A method of treating a surface to remove unwanted material therefrom, including providing a foamed glass article formed from a starting mixture including glass, a carbonate foaming agent, and a devitrification agent selected from the group potassium phosphate, potassium phosphate tribasic, sodium phosphate and combinations thereof, and contacting the surface with the foamed glass article while providing relative movement between the surface and the article. The crystal silica content of the foamed glass body is less than 1 weight percent. The surface is treated by sanding, rubbing, scraping, degreasing, polishing, cleaning, smoothing, depilling, grooming, stripping, degumming, and combinations thereof. The surface is selected from the group comprising wood, metal, plastic, fiberglass, porcelain, glass, enameled surfaces, ceramic, concrete, or tile, and belongs to a member of the group comprising pools, spas, griddles, grills, fryers, bottles, glassware, cement pieces, marble, granite, monuments, skin, animal hides, textiles, garments.

Very low crystalline silica foamed glass and methods of using the same

Modular plastic structural composites formed from a mixture of (A) high density polyolefin and one or both of: (B) a thermoplastic-coated fiber material, or (C) polystyrene, poly(methyl methacrylate), or a combination thereof. Composites molded in the form of I-Beams and bridges constructed therefrom are also disclosed.

Use of recycled plastics for structural building forms

A method of making a foamed glass body, including preparing an admixture of powdered glass, at least one carbonate based foaming agent, and at least devitrification inhibitor, heating the admixture to a first temperature to soften the glass, heating the admixture to a second, higher temperature to foam the softened glass into a foamed glass body, and cooling the foamed glass body. The crystal silica content of the so-formed foamed glass body is less than 1 weight percent.

An immiscible polymer blend that includes an amount of poly(trimethylene terephthalate) (PTT) and an amount of poly(methylmethacrylate) (PMMA). A method for preparing an immiscible polymer blend by (a) identifying a first polymeric component and a second polymeric component as immiscible when blended; (b) combining the first polymeric component and the second polymeric component; and (c) mixing the first polymeric component and the second polymeric component to produce an immiscible polymer blend that includes structures in the blend having a maximum size of less than about 1,000 &#x3bc;m is also presented. An article that includes an immiscible polymer blend of poly(trimethylene terephthalate) (PTT) and poly(methylmethacrylate) (PMMA) and an article formed from an immiscible polymer blend prepared by the method of the present invention are also presented.

An immiscible polymer blend including a first polymer component including a paint polymer phase and a second polymer component immiscible with the first polymer component and selected from polyolefins and polymethylmethacrylate (PMMA). A method of recycling paint by blending a first polymer component including a paint polymer phase with a second polymer component immiscible with the first polymer component and selected from polyolefins and polymethylmethacrylate (PMMA) is also presented.

Method of recycling paints as a component of an immiscible polymer blend

A system for and method of analyzing a cullet stream prior to batch formulation in glass manufacturing. Cullet is fed onto a conveyor where a real-time composition analysis is performed. Contaminants are optionally removed, and a determination is made as to whether the cullet batch color is consistent with a predetermined tolerance threshold. If necessary, the glass batch formulation is modified in view of the cullet analysis. Virgin raw materials requirements of the modified glass batch formulation may then be communicated to the batch controller before sending batch ingredients to the mixing stage and completing the overall glass manufacturing process.

System for and method of batch analysis and optimization for glass manufacturing

Certain preferred embodiments of the present invention provide a system for and method of analyzing and cleaning a cullet stream prior to bottle manufacturing. In accordance with certain aspects of the present invention, the system includes a raw materials feeder, a mixing stage, a melting stage, a bottle-forming stage, a cooling/annealing stage, an inspection stage, and a batch controller. The raw materials feeder further includes a cullet bin within which is cullet supply, a feeder, an analysis device, and removal assembly. Certain preferred embodiments of the method include the steps of feeding cullet onto the conveyor, performing real-time composition analysis of the cullet, removing contaminants from the cullet, determining whether the cullet batch is consistent with a predetermined tolerance threshold, adjusting the glass batch formulation, sending the batch ingredients to the mixing stage, and then completing the overall glass manufacturing process.

A method of determining the constituents and impurities in mixed-color cullet to facilitate use of mixed-color cullet in glass manufacture is provided. A glass batch formulation is adjusted based on the measured characteristics of supplied mixed-color cullet. More specifically, certain preferred aspects of the present invention include the steps of providing quantity of mixed-color cullet, collecting at least one sample of the mixed-color cullet, performing, either singularly or in combination, particle size analysis, particle color analysis, or organics analysis of the mixed-color cullet, optionally storing the analysis results, determining a glass batch formulation, providing the cullet specification and the batch formulation to a glass manufacturer, and adjusting glass batch formulation based on the cullet specification to ensure consistent glass quality.
