A decorative substrate includes a base, and a texture layer arranged on the base. A plurality of grating grids are arranged on a surface on the side of the texture layer from the base. The plurality of grating grids includes a plurality of grating structures annularly arranged around a central point. Each grating structure includes a plurality of strip-shaped protrusions, which are sequentially arranged in a radius direction of a circle with the central point as its center. In the grating grids, each strip-shaped protrusion includes a first surface close to the central point, and a second surface away from the central point. The first surface and the second surface are connected to a third surface of the strip-shaped protrusion. An included angle formed by the first surface and the third surface is less than or equal to an included angle formed by the second surface and the third surface.

A laminating device, a processing method for the electrode plate assembly, and a thermally bonding device for electrode plates are provided. The laminating device includes a laminating platform, a first driving roller assembly, and a second driving roller assembly. A first spacing d1 is arranged between the first driving roller assembly and the second driving roller assembly. A length of each of the electrode plate units is L, d1 is less than L, or d1 is greater than L, and a ratio between d1 and Lis a non-integer.

A multilayer tube for transporting fluid is disclosed. The multilayer tube includes a first layer including a polyolefin blend including a first polypropylene and a second polypropylene. The first polypropylene and second polypropylene copolymer have different and non-overlapping melt flow indices. The multilayer tube includes a second layer including a thermoplastic vulcanizate including a thermoplastic resin and an at least partially cured elastomer.

A core structure (300) for a composite panel for an aircraft, for example a door fairing for a landing gear bay, including a sandwich structure in which core cells (301) are sandwiched between first and second body sides (skins 303, 305). The core cells are square or rectangular in shape and each have a void formed by cell walls (307). The first and second body sides and the cell walls include laminated composite material of multiple layers. Drainage holes (320) in the cell walls form one or more direct drainage paths (P2, P3) for the flow of fluid from the core structure. The core cells include first and second sheets of cells reversibly mounted to each other, such that the void of each cell is formed in part by the first sheet and in part by the second sheet.

According to various embodiments, an electronic device may include: a first housing; a second housing; a hinge device connecting the first housing and the second housing in a foldable manner; and a flexible display disposed to be supported by the first housing and the second housing, and including a display panel and a protection layer laminated on the display panel. The protection layer of the flexible display may include a first layer laminated on the display panel; a second layer laminated on the first layer; a third layer laminated on the second layer; and a coating layer formed on an upper surface of the third layer, wherein the third layer has a thickness greater than a thickness of the second layer.

The presently disclosed subject matter generally relates to recyclable insulation material for shipping containers, groceries bags, etc., machines for making the recyclable insulation material, and methods for the making the recyclable insulation material. In one aspect, an insulation product may include a first layer and a first continuous paper sheet formed into a first plurality of flexible loops disposed on and attached to the first layer and defining a first plurality of air channels that extend in a direction that is substantially perpendicular with a machine direction of the insulation product. A take up factor of the first continuous paper sheet to the first layer may be greater than 1:1.

The present invention relates to a panel element, such as a floor panel, a wall panel, a ceiling panel or a decking panel. The panel element comprises a first substrate made of a synthetic composite material comprising at least 20% by weight of mineral material, and a second substrate made of a distance material embedded or recessed in the first substrate. The distance material has a bulk density which is lower than a bulk density of the synthetic composite material. The panel element comprises at least two opposing side edge portions formed solely by the first substrate. A method for forming a panel element and an extrusion device configured to form a panel element are also provided.

A corrugated tubular member 1 has a corrugated surface shape on an outer circumferential surface 2. At least a part of the corrugated tubular member 1 in a radial direction is formed as a foamed layer 4. The entirety of the corrugated tubular member 1 including the outer circumferential surface 2 and an inner circumferential surface 3 in a thickness direction is integrally molded. The corrugated tubular member 1 satisfies the following (a) or (b). (a) The corrugated surface shape is formed on the inner circumferential surface 3 in addition to the outer circumferential surface 2, and 3L<2L is satisfied. (b) The inner circumferential surface 3 does not have the corrugated surface shape.

A method for manufacturing a synthetic non-perforated drainable material is disclosed herein. Generally, the method includes injecting a coating material with air, applying the air-injected coating material to the first side of the material, and curing the air-injected material such that it adheres. Once cured, the material has a highly efficient drainage rate that remains consistent throughout the life of the material.

The presently disclosed subject matter generally relates to recyclable insulation material for shipping containers, groceries bags, etc., machines for making the recyclable insulation material, and methods for the making the recyclable insulation material. In one aspect, an insulation product may include a first layer and a first continuous paper sheet formed into a first plurality of flexible loops disposed on and attached to the first layer and defining a first plurality of air channels that extend in a direction that is substantially perpendicular with a machine direction of the insulation product. A take up factor of the first continuous paper sheet to the first layer may be greater than 1:1.
