Provided is a technique relating to a slurry for a non-aqueous secondary battery adhesive layer that enables simple detection of an adhesive layer formed on a battery member while also causing a secondary battery to display good battery characteristics. The adhesive layer is formed using a slurry for a non-aqueous secondary battery adhesive layer that contains a polymer (A), an organic coloring material, and water, and in which the organic coloring material has a proportional content of not less than 0.1 parts by mass and not more than 50 parts by mass per 100 parts by mass of the polymer (A).

A reduced weight, reduced density gypsum panel that includes high expansion vermiculite with fire resistance capabilities that are at least comparable to (if not better than) commercial fire rated gypsum panels with a much greater gypsum content, weight and density.

The present invention is directed to a flame-retardant building panel comprising a body having a first major surface opposite a second major surface, an inorganic coating atop the first major surface, the inorganic coating comprising a flame retardant component that includes a phosphate compound, and a metal complexing agent. In other aspect, the invention is a method of forming a flame-retardant building panel comprising: a) applying an inorganic coating composition to a major surface of a body; and b) drying the inorganic coating composition at an elevated temperature.

Disclosed is an acid-modified flour and a method of making the acid-modified flour. The acid-modified flour is desirably prepared using a dry milling process. A starting flour is combined with a strong acid to form a mixture. The mixture is heated. A neutralizer is added to increase the pH of the mixture. If desired, the mixture can be dried and any agglomerates can be removed. The acid-modified flour can be used as a binder in a slurry for preparing one or more gypsum layers in a gypsum board.

A method for manufacturing a substrate having a resin layer, including, in this order: (1) providing the resin layer formed on a support, the support being larger than the outer size of the substrate; (2) bonding the resin layer supported on the support to the substrate; (3) removing an end portion of the resin layer disposed on the end portion of the support and in no contact with the substrate, by a solvent capable of dissolving the resin layer; and (4) peeling off the support from the resin layer.

Disclosed herein is an improved cover board product with a panel comprising a top surface layer comprised of paper or a fiberglass web; a bottom surface layer comprised of paper, a fiberglass web, nylon film, polyester film, polypropene film, or textiles; and a core layer comprised of paper and thermoplastic fragments connected by a thermoplastic bonding resin. The thermoplastic bonding resin is in a random pattern to less than 100% of the paper and thermoplastic fragment surface area.

A method for preparing a bifunctional film, including: (a) drying a first polymer solution to form a film to form an anti-adhesion layer, and (b) drying a second polymer solution over the anti-adhesion layer to form a film to form an attachment layer. The first polymer solution includes a first hydrophobic solution and a first hydrophilic solution, and in the first polymer solution, the weight ratio of the solute of the first hydrophobic solution to the solute of the first hydrophilic solution is 1:0.01-1. Moreover, the second polymer solution is composed of a second hydrophilic solution.

Object of the present invention is a process for manufacturing a membrane adapted for coupling to a fabric or other supports that can be used in the field of the clothing or furnishing, and so-obtained product.

The present invention belongs to the technical field of energy conversion devices, which provides an rGO-PEI/PVDF pyroelectric thin film, and the method for preparing the film, as well as a self-energized bracelet produced based on such film, which utilizes the reduced graphite oxide after modified by polyethyleneimine (PEI) (rGO-PEI) as photothermal conversion material, and the silver-plated polarized polyvinylidene fluoride (PVDF) film as pyroelectric conversion material. The rGO-PEI photothermal material is fixed to the surface of the PVDF through a transparent film, and prepare the self-energized bracelet based on it. The obtained bracelet has an output power of up to 21.3 mW/m2, and does not require additional mechanical devices to control the temperature during operation, wherein, the thermoelectric conversion, rectification, storage and application are realized through temperature fluctuation produced by absorbing sunlight during doing outdoor sports, utilizing temperature difference of air flow, and sweeping gesture, etc.
