摘要:
A building element (1) that is suitable for use as a structural element in wet areas or external decking. The building element (1) comprises a rigid substrate (2) having an upper face (3). Over the first face (3) lies a radiation curable resin (4) into which a layer of reinforcing material (5) is at least partially embedded. The reinforcing material (5) and resin (3) can be applied separately or together onto the first face (3) of the rigid substrate (2) or in some cases can be applied to both faces. An apparatus and method for producing the building sheet are also disclosed.

A novel gypsum wallboard having a textile reinforcing material embedded within a gypsum core together with randomly oriented chopped glass fibers, as well as a novel process for constructing such gypsum wallboards.
摘要:
A composite building article is configured with one or more subsurface interfacial zones provided to improve the durability of the article. Each subsurface interfacial zone is made of a matrix of fiber cement and radiation curable material. The radiation curable material forms an interlocking network with the fiber cement to provide a interfacial zone against ingress of environmental agents that can degrade the article. The number, configuration and distribution of the subsurface interfacial zones can vary dependent on the desired characteristics of the final product. The subsurface interfacial zones also improves the adhesion between exterior coatings and the substrate as the interfacial zones can be integrally formed with the substrate as well as exterior coating layer.
摘要:
Cement wallboards and methods for their preparation are disclosed. The wallboards comprise two scrim layers and one mat layer. The wallboards have a smooth surface, are strong, lightweight, and easy to score and snap. Tiles can be readily adhered to the boards. The wallboards can be used in general commercial and residential construction, and are particularly attractive for use in high water/moisture areas such as bathrooms and shower enclosures.
摘要:
Schichtplatte (100), umfassend eine Mittelschicht (1) und zwei Außenschichten (2;3), bei der die Mittelschicht aus polymerem Kunststoff besteht, in sich flexibel ist und eine grobzellige, wabenartige Struktur mit offenen Zellen (4) zur Ober- und Unterseite der Mittelschicht hin aufweist. Die Außenschichten bestehen aus einem abgebundenen, mit Kunststoffzusätzen flexibilisierten Mörtel und sind mit einem Bahnmaterial armiert, wobei die Außenseite (5) der ausgehärteten Außenschicht putzartig rau gehalten ist. Die Schichtplatte kann gebogen werden, ohne dass die Außenschichten abplatzen.
摘要:
A reinforced, lightweight, dimensionally stable panel capable of resisting shear loads when fastened to framing equal to or exceeding shear loads provided by plywood or oriented strand board panels. The panels employ a core of a continuous phase resulting from the curing of an aqueous mixture of calcium sulfate alpha hemihydrate, hydraulic cement, an active pozzolan and lime, the continuous phase being reinforced with alkali-resistant glass fibers and containing ceramic microspheres, or a blend of ceramic and polymer microspheres, or being formed from an aqueous mixture having a weight ratio of water-to-reactive powder of 0.6/1 to 0.7/1 or a combination thereof. At least one outer surface of the panels may include a cured continuous phase reinforced with glass fibers and containing sufficient polymer spheres to improve nailability or made with a water-to-reactive powders ratio to provide an effect similar to polymer spheres, or a combination thereof.
摘要:
In one embodiment, a reinforced fiber cement article comprising a fiber cement piece and a reinforcing fixture bonded to a portion of the fiber cement piece for improving the performance, strength and durability of the fiber cement piece. The reinforcing fiber cement article could be used as or in conjunction with a siding plank assembly, which further comprises an interlocking feature that allows the siding plank to be stacked with other siding planks in a manner such that a uniform and deep shadow line is created. The interlocking feature sets the gauge of the exposed plank face and allows for leveling of the plank during installation. The reinforcing fixture could also serve as a thick butt piece or a plastic spline that produces a deep shadow line. A cementitious adhesive is used to bond the reinforcing fixture to the fiber cement piece.
摘要:
Sealable liquid-tight containers and methods for economically manufacturing such containers for storing and dispensing substances and any other purposes for which conventional sealable liquid-tight containers are utilized. The containers are readily and economically formed from mixtures of hydraulically settable binders such as hydraulic cement, gypsum and clay with water. Appropriate additives can also be added to the mixture which impart desired characteristics and properties to both the mixture and the hardened containers. The mixtures can be utilized to form containers by various methods. One method involves forming the containers without substantial mixing of the mixture, compacting the mixture and hydrating the mixture. Other methods involve molding the mixture, extruding the mixture and forming sheets from the mixture to be converted into containers. The components may also be dried, coated, lined, laminated and/or receive printing.
摘要:
Compositions, methods and systems for manufacturing arcticles, including containers and packaging materials, from hydraulically settable and inorganically filled materials are disclosed. Suitable compositions are prepared by mixing together a hydraulically settable binder or organic binder, water, and appropriate additives, such as aggregates, fibers, and rheology-modifying agents, which impart predetermined properties so that an article formed therefrom has the desired performance criteria. The desired article can be molded from the mixture using a variety of moding processes including: die pressing, injection modling, blow molding, jiggering, wet sheet molding, and dry sheet molding. The sheet forming processes require the mixture to first be fashioned into a sheet, such as by the use of an extruder (12) or rollers, after which the sheet is formed, it is hardened. Printed indicya and a coating can then the applied.
