摘要:
The invention of this application provides an artificial stone wall material comprising an inorganic fine particle component having a size range of 180 μm to 9.5 mm and an inorganic finer particle component having a size range of less than 180 μm and a resin component. The resin component containing 5 wt % or more of a transparent inorganic fine particle component as the inorganic particle component and a concavo-convex surface wherein a maximum height between concavity and convexity ranges 1 mm to 100 mm. Further, the transparent inorganic fine particle component, which is exposed on the concavo-convex surface, is studded with sparkling points which change based on irradiation and movement of natural light or artificial light. The artificial stone wall material provides a novel means for finishing a wall surface which permits easy design of a wall surface and projection of the effect of the design.
摘要:
A liquid composition, active curing additive for water or solvent borne surface coatings and sealants such: latex products, paints, putties, caulks, sports track and court construction, asphalt or coal tar seal coating, asphalt paving, micro-seal, roof tars, asphalt emulsions, crack sealants, and the like is provided. The additive functions to significantly reduce the amount of time required for the surface coating to cure and thereby allows the coated or sealed surface to be quickly returned to service. Preferably, the additive is composed of a composition of water; calcium chloride granules; citric acid granules; and an ammonium dispersing composition. Alternatively, aluminum sulfate may be utilized in place of calcium chloriade and citric acid. This formulation, when added to a liquid surface sealant or coating, will create an active process within the film of the said sealant or coating which draws water out of the film extremely fast, thereby reducing the amount of time required for the surface coating or sealant to cure.

摘要:
An electrically conductive material used for shielding against electromagnetic waves and comprising a binder, a mixture of graphite and amorphous carbon, and sand. It has been shown that this mixture has enhanced shielding properties, particularly in the 100 MHZ range. The graphite/carbon mixture preferably makes up 25-75% of the total weight of the material. The binder may be cementitious. Said material may also be used in conductive floors, electrical heating equipment, light conductors, heating elements, ground connections, resistors, capacitors and antennas.

The present invention relates to a process for producing briquetted and pressed granular material and the use thereof for coloring building materials, such as concrete, and organic media, such as paint systems, plastics and colored pastes.
摘要:
Methods and systems for readily and economically manufacturing hydraulically settable articles, particularly containers, from microstructurally engineered hydraulically settable mixtures wherein the mixture is extruded into a sheet that is feed through a plurality of sets of rollers so as to form the sheet into the desired thickness. The sheet is then pressed between a male die of a desired shape and a female die having a substantially complimentary configuration of the male die shape to immediately fashion a portion of the sheet into a form stable shape for the desired article. To assist in imparting form stability, the dies can be heated or cooled. Once the article has obtained form stability, the article is removed from the dies and dried under heated air to gain strength. The article can then be cut from the sheet and receive printing or a coating, if desired, prior to packaging, shipping, and use.
摘要:
Containers incorporating a hydraulically settable structural matrix including a hydraulically settable binder such as cement for use in the storing, dispensing, and/or packaging of food and beverage products are disclosed. The disposable and nondisposable food and beverage articles of manufacture have high tensile, compressive, and flexural strengths, and are lightweight, insulative (if desired), inexpensive, and more environmentally compatible than those currently used. These disposable containers and cups are particularly useful for dispensing hot and cold food and beverages in the fast food restaurant environment. The structural matrix of the food and beverage containers includes a hydraulic cement paste (formed from the reaction of water with, e.g., a portland-type cement) preferably in combination with a rheology-modifying plasticizer, such as methylhydroxyethylcellulose, various aggregate materials, and fibrous materials, which provide desired properties at a cost which is economical.
摘要:
A cementitious mixture includes hydraulic cement, fly ash, and an effective amount of unfired nature finely divided material, such as a clay, containing at least about 35% alumina, to accelerate the early strength of a mix. A method of accelerating early strength in a cementitious mix comprises the adding of alumina in the form of an unfired raw material, such as clay, in an effective amount in such mix.
摘要:
A composition of matter comprising naturally-occurring humic allophane soil or Ando soil as an essential ingredient admixed with a binder material, said composition is useful in preparation of solid media effective as deodorant, absorbent, adsorbent and the like for treating fluids, in particular contaminated water and malodor air.
