摘要:
Disclosed are solar-reflective roofing and other building materials having high reflectance of near-infrared radiation and high transmission of radiation in the visible light range and a substantial emissivity so as to reduce the heat island effects experienced by the articles while also maintaining an aesthetically pleasing appearance. Also disclosed are related methods for fabrication of such materials.
摘要:
The present invention relates to the technical field of waterproof materials, and particularly to a high-strength wind-resistant skid-resistant waterproof underlayment. The high-strength wind-resistant skid-resistant waterproof underlayment comprises a first non-woven fabric layer, a first film layer, a first asphalt layer, a gridding cloth layer, a second asphalt layer, a second non-woven fabric layer, a second film layer and a third non-woven fabric layer laminated successively; the first film layer and the second film layer are waterproof elastic films respectively. The object of the present invention is to provide a high-strength wind-resistant skid-resistant waterproof underlayment. The waterproof underlayment formed by structures such as a first film layer and a second film layer and the like can be fixed through nails on a roof made of a wood structure, etc., and the construction is quick, convenient, and labor-saving, and the waterproofness is good.
摘要:
A roofing shingle includes strata that are stacked and laminated together by adhesive. Each of the strata may have a strata width that differs from the other strata. Each of the strata may include a substrate, a top asphalt layer on top of the substrate, granular matter on the top asphalt layer, a bottom asphalt layer on a bottom of the substrate, and mineral matter on the bottom asphalt layer.

The present invention relates to a waterproof material, wherein film layers are set between non-woven fabric layers, an asphalt layer is set between the film layers, and a net reinforcement layer is set within the asphalt layer. The advantages of the present invention include: (1) film layers are formed by laminating it on the compositing surfaces of the upper and lower non-woven fabric layers, which overcomes the drawback of water leaking in the background art, prevents the leaking of asphalt into the non-woven fabric or out of the non-woven fabric during the compositing process, so that the environmental pollution during transportation and application is avoided; (2) a glass-fiber netlike reinforcement layer is set within the asphalt layer, so that not only the tensile strength and compressive strength of the asphalt layer, but also the tensile strength and tear strength of the roofing underlayment material are improved; (3) the thickness and number of film layers are set to ensure the temperature-resistance and puncturing-resistance of film layers.
摘要:
A method, system and device for reproducing sound. The device may include an elongated strip of material having a ridge substantially extending the length and width of the elongated strip. The elevation of the ridge may vary along the length of the elongated strip to produce sound when contacted by a wheel of a vehicle travelling substantially along the length of the elongated strip.
摘要:
A flashing material for a building structure is provided. The flashing material includes a flexible water-resistive membrane having an upper textured surface with a series of separate, laterally paced-apart, elongate spacers bonded thereto. The elongate spacers can be polymeric filaments that define an air space and drainage paths across the upper surface of the membrane. Preferably, the filaments have a series of depressions formed therein that provide transverse drainage paths across the filaments. Sill, decking and other building structure assemblies and methods of making the flashing material are provided.
摘要:
A plate-shaped structural component has a concrete substrate that contains a reinforcement mesh of several micro-plies with a respective mesh width of approximately 5 to 60 mm. At least one additional panel is attached sandwich-like on the concrete substrate by mechanical anchoring and by adhesive connection.
