摘要:
A hinge for use in inorganically filled composite materials is provided. The hinge has an inorganically filled structural matrix comprising a water-dispersable organic polymer binder, an aggregate material, and a fibrous material. The hinge allows inorganically filled materials to be bent along a line without breakage of the material. The hinge is preferably formed by scoring a formed sheet of inorganically filled material. The hinge is particularly useful in containers that require bending of various container parts, such as in food containers and boxes made from inorganically filled materials.

A thin durable decorative coating is applied to a concrete substrate such as a floor by applying a 0.1 mm coating of runny cement-plus-fines (water:cement=1:1) to the substrate. Capillary suction by the substrate very rapidly dewaters the coating, which is compacted by atmospheric pressure and matures to form an inseparable coating on the substrate. The fines may include colourings, mica or other additives to enhance the final appearance.

Containers use in the storing, dispensing, packaging, and/or portioning of food and beverage products are disclosed. The disposable and nondisposable food and beverage containers are manufactured from aggregates held together by organic binders in order to be lightweight, insulative, inexpensive, and more environmentally compatible than those currently used for storing, dispensing, packaging, or portioning such products. The food and beverage containers of the present invention are particularly useful for dispensing hot and cold food and beverages in the fast food restaurant environment. The structural matrices of the food and beverage containers include a hydrated organic binder paste (formed by mixing the binder with water) in combination with appropriate aggregate materials, such as fibers to add flexibility and strength, glass spheres to make the product more lightweight and insulative, or clay to make the product extremely inexpensive yet strong. In addition, the structural matrix may include entrained air voids to make the final product even more lightweight and insulative. These combinations allow the manufacture of food and beverage at a cost which is economically justified in comparison to conventional paper, plastic, or styrofoam products.

Compositions and methods for manufacturing containers from sheets having a hydraulically settable matrix. Suitable compositions are prepared by mixing together a hydraulic binder, water, and appropriate additives (such as aggregates, fibers, and rheology-modifying agents) which impart predetermined properties so that a sheet formed therefrom has the desired performance criteria. Hydraulically settable sheets are formed from the mixture by extrusion, then calendering the sheets using a set of rollers and then drying the sheets in an accelerated manner to substantially harden the sheets. The resulting hydraulically settable sheets may have properties substantially similar to sheets made from presently used materials like paper, cardboard, polystyrene, or plastic. The sheets can be laminated, corrugated, coated, printed on, scored, perforated, cut, folded, rolled, spiral wound, molded, assembled and seamed to mass produce articles of manufacture from the sheets such as food and beverage containers.
摘要:
The quantity of water on the surface of sand particles is reduced by applying an impact force, e.g. centrifugal force created by a rotating disc. The sand particles thus treated are especially suitable for preparing a green concrete compound or a cement mortar by mixing them with water, gravel and cement.
摘要:
Methods for producing compositions that prevent, mitigate or delay the onset of corrosion of iron or steel (e.g., plain carbon steel) components used as reinforcement or otherwise at least partially embedded in carbonated concrete composite materials and objects based on carbonatable calcium silicate cement are disclosed.
摘要:
This invention relates to a biodegradable composition comprising a low carbon footprint binder comprising a silicate, and bio-based aggregates. The invention also relates to the binder thereof, products, including insulation material and wall boards/panels, formed from the binder and the composition, a method of preparing the binder and composition and/or the products, and a method of using the binder and composition and/or the products in construction.
摘要:
The disclosure provides a method of decreasing the water load needed to form a fibrous panel. The process includes admixing a mineral wool, a cellulose, and a binder to provide a pre-mixed slurry, admixing a mineral filler with water to provide a mineral filler slurry, admixing the pre-mixed slurry and the mineral filler slurry to form a dispersion, flowing the dispersion onto a foraminous support wire to provide a green board, dewatering the green board to form a dewatered green board and drying the dewatered green board to provide a fibrous panel.
摘要:
Methods, compositions, and systems for treating a well are included. A method comprises introducing a treatment fluid comprising a calcium aluminate cement, a cement set retarder, and water into a wellbore. The method further comprises removing a portion of the treatment fluid from the wellbore.
