A coating created entirely from plant-derived ingredients is disclosed. Illustrative embodiments of the coating may be particularly well suited for use on leather-like materials created from epoxidized natural rubber-based formulations. Illustrative embodiments of the coating created may be comprised of substantially the reaction product between epoxidized vegetable oil and a polyfunctional naturally occurring acid (such as citric acid). Illustrative embodiments this reaction product may be used to produce porosity-free castable resins and vulcanize rubber formulations based on epoxidized natural rubber. Materials made from disclosed materials may be advantageously used as leather substitutes.

A sound damping wallboard and methods of forming a sound damping wallboard are disclosed. The sound damping wallboard includes a gypsum layer having a first side with a first gypsum surface, a first encasing layer at least partially covering the first gypsum surface to form a first encasing layer portion, and a sound damping layer on the first side covering at least part of the first encasing layer portion.
摘要:
A cellular structure may include a plurality of cells each cell of the plurality of cells having a sixteen-cornered cross section. The sixteen-cornered cross section may include sixteen sides and sixteen corners. Each cell may include a plurality of longitudinal walls extending between a top and a bottom of the cell, the longitudinal walls intersecting to create corners of the cell.

A lightweight antiballistic plate assembly includes a ceramic antiballistic plate that is strengthened with a superhard protective layer attached to the strike face of the antiballistic plate. In one embodiment, a strike face of the plate has a layer of superhard material, such as polycrystalline diamond (PCD), attached by sintering. In one embodiment, the ceramic antiballistic plate is made from a mixture of silicon carbide and superhard protective strike face comprising a material selected from the group consisting of polycrystalline diamond (PCD), polycrystalline cubic boron nitride (PCBN), thermally stable polycrystalline diamond and combinations thereof.

Disclosed herein is a sound absorbing structure which includes at least one sound-permeable nanofiber layer and at least one sound absorbing layer; in which, the sound-permeable nanofiber layer is placed alongside of the sound absorbing layer.
摘要:
A three-dimensional object comprises substantially planar or flat substrate layers that are folded and stacked in a predetermined order and infiltrated by a hardened material. The object is fabricated by positioning powder on all or part of multiple substrate layers. On each layer, the powder is selectively deposited in a pattern that corresponds to tiles that each have a slice of the object. For each slice, powder is deposited in positions that correspond to positions in the slice where the object exists, and not deposited where the object does not exist. The tiles of each substrate layer are folded and aligned in a predetermined order. Multiple folded substrate layers mat be combined into a single stack. The powder is transformed into a substance that flows and subsequently hardens into the hardened material in a spatial pattern that infiltrates positive regions, and does not infiltrate negative regions, in the substrate layers.
摘要:
A laminated packaging material for food packaging, comprises a core layer of paper or paperboard, which on a first side intended to be directed towards the outside of a packaging container, has, in the following order, a dry pre-coating for receiving a printed décor of an aqueous, pigment-based, ink-jet printing ink, a pigment-based ink-jet printed ink décor layer and further laminated onto the printed décor layer, a protective outermost layer of a thermoplastic polymer. Also disclosed is a method for manufacturing of the packaging laminate and to a packaging container that is made from the laminated packaging material as well as to a pre-coating composition for use in the laminated packaging material and in the manufacturing thereof.
摘要:
An ovenable paper container containing an inner liner, an outer liner, and an intermediate or corrugated paper layer positioned between the inner liner and the outer liner. The ovenable paper container can be used to heat and/or cook food and then be used as a serving container without the danger of causing burns.
摘要:
There is described a method of creating a transparent polymer window (W) with a field of lenses (L) in a security paper substrate (1), the method comprising the steps of (i) providing a security paper substrate (1), (ii) forming an opening (10) into the security paper substrate (1), (iii) laminating a transparent film (5; 5*) onto a first side (I) of the security paper substrate (1) in such a way as to close the opening (10) at one end, and (iv) filling the opening (10) with transparent polymer material (2). In one embodiment, the transparent film (5) comprises a field of lenses (L) and is laminated onto the first side (I) of the security paper substrate (1) in such a way as to form lenses (L) on the first side (I) of the security paper substrate (1) in register with the opening (10). In another embodiment, the field of lenses (L) is replicated into the transparent polymer material (2) applied in the opening (10) in such a way as to form lenses (L) on a second side (II) of the security paper substrate (1), opposite to the first side (I), in register with the opening (10). Also described is a device designed to fill the opening (10) formed into the security paper substrate (1) with the transparent polymer material (2) and a processing machine comprising the same.
