摘要:
Board, characterized in that it consists at least of a substrate which is formed at least of a gypsum-based and/or cement-based basic material layer with a compressive strength of 30 kg/cm 2 and a resin-based covering provided on at least one side of the substrate, in the form of a laminate layer directly pressed onto the substrate, also named "DPL" (Direct Pressure Laminate).
摘要:
The present invention pertains to a layered structure intended to be used for protecting wind turbine blades against lead ing edge erosion. The layered structure is capable to resist the impact energy of incoming particles and/or rain drops and to damp the kinetic energy of such impacting object so that the covered structure does not suffer any negative effect upon the impact. The layered structure of the present invention is beneficial since, amongst other benefits, it reduces operating cost and wind turbine downtime. The present invention also provides a method for producing the layered structure of the present invention. It also pertains to the use of the layered structure of the present invention for protecting the leading edge of wind turbine blades against erosion.
摘要:
A reinforced insulation assembly is disclosed. The assembly includes insulation, a reinforcement layer, and an adhesive for attaching the reinforcement layer to a surface of the insulation. The reinforced layer is fully immersed within the adhesive and penetrates the surface of the insulation.

The present disclosure provides a multilayer film. In an embodiment, the multilayer film includes a sealant layer. The sealant layer includes from (i) 50 wt% to 95 wt% ethylene copolymer having a density of at least 0.918 g/cc and (ii) from 50 wt% to 5wt% of a 1-butene polymer having a density of at least 0.913 g/cc.
摘要:
A three-dimensional substrate has a first surface, a second surface, land areas and comprises three-dimensional protrusions extending outward from the second surface of the three-dimensional substrate. The three-dimensional protrusions are surrounded by the land areas. The three-dimensional substrate is a laminate comprising at least two layers in a face to face relationship. The second layer comprise a tissue layer facing outward from the second surface of the three-dimensional substrate. The tissue layer comprises at least 80% pulp fibers by weight of the tissue layer.
摘要:
A group of glass compositions in the Li 2 O-Al 2 O 3 -SiO 2 -B 2 O 3 family that can be chemically strengthened in single or multiple ion exchange baths containing at least one of NaNO 3 and KNO 3 for a short time (2-4 hours) to develop a deep depth of layer (DOL). In some instances, the DOL is at least 70 µm; in others, at least about 100 µm. The ion exchanged glasses have a high damage resistance (indentation fracture toughness ranging form greater than 10 kgf to greater than 50 kgf) that is better than or at least comparable to that of sodium aluminosilicate glasses.
