Method for repairing delamination and moisture by heat, pressure and adhesive
A method for repairing aircraft window laminates in which two plies have become separated to create a void, and wherein moisture may have entered through an edge of the window laminate and into the void. The method includes the steps of: placing the window laminate in a vacuum bag and inserting the vacuum bag containing the window laminate into an oven or autoclave for a minimum of ten minutes at a minimum temperature of 120 degrees Fahrenheit to remove the moisture between the plies; removing the vacuum bag and window laminate from the oven, and removing the window from the vacuum bag; forcing a needle on a syringe through the edge of the window laminate in the area of the void; and injecting an adhesive in the syringe into the void to fill the void with the adhesive.
Roof Cover Board Derived From Engineered Recycled Content
An improved cover board product with a panel comprised of three discrete layers: a top surface layer comprised of either paper or a fiberglass web, a bottom surface layer comprised of either paper or a fiberglass web, and a core layer comprised of discrete paper fragments and polypropylene fragments, which are connected by use of a thermoplastic bonding resin, including polyethylene. The bonding resin is generally attached in a random pattern to less than 100% of the paper fragment and polypropylene fragment surface area. The paper fragments are generally shaped as irregular plates. The polypropylene fragments can have multiple shape types. The two different fragment types are randomly distributed in the core layer relative to each other. The core layer includes small voids in and around the particles, which improves flexibility. The core layer is attached to the top and bottom surface layers by use of a thermoplastic adhesive, including polyethylene.
Carbon nanotube sheet structure and method for its making
A carbon nanotube (CNT) sheet containing CNTs having a median length of at least 0.05 mm and an aspect ratio of at least 2,500; L arranged b a randomly oriented, uniformly distributed pattern, and having a basis weight of at least 1 gsm and a relative density of less than 1.0. The CNT sheet is manufactured by applying a CNT suspension in a continuous pool over a filter material to a depth sufficient to prevent puddling of the CNT suspension upon the surface of the •filter material, and drawing the dispersing liquid through the filter material to provide a uniform CNT dispersion and form the CNT sheet. The CNT sheet is useful in making CNT composite laminates and structures having utility for electromagnetic wave absorption, lightning strike dissipation. EMI shielding, thermal interface pads, energy storage, and heat dissipation.
Building board having high fastener sealability
A building board, particularly a gypsum board, can have a high fastener sealability if protected by the combination of thin layers of an extruded polymer film and a thermoplastic coating layer. The combination of extruded polymer film and thermoplastic coating layer is designed such that the gypsum board can also tolerate overdriven fasteners, thus exceeding the requirements of ASTM D1970-15.
Porous backplane for electro-optic display
A backplane for an electro-optic display including an electrode and a substrate. The substrate may be porous to liquids, e.g., water, and may formed, from cellulose or a similar hydrophilic polymer. The electrode is desirably also porous to the same liquid as the substrate, so that the electrodes do not form liquid-impervious areas on the substrate. For example, when the liquid is water (or an aqueous solution) the electrodes may be formed of a hydrophilic carbon black, which may be coated or screen-printed on to the substrate.
FLOUR BINDER FOR GYPSUM BOARD, AND RELATED METHODS, PRODUCT, AND SLURRIES
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.
METHOD OF PRODUCING A PLANT GROWTH SUBSTRATE
The present invention relates to a method of producing a coherent growth substrate product formed of man-made vitreous fibres (MMVF), comprising the steps of (vi) providing MMVF; (vii) providing an uncured binder composition; (viii) providing a superabsorbent polymer; (ix) forming a mixture of the MMVF, the uncured binder composition and the superabsorbent polymer; (x) curing the uncured binder composition in the mixture to form the coherent growth substrate product; wherein the uncured binder composition comprises at least one hydrocolloid.
Underbody shield compositions and articles that provide enhanced peel strength
A thermoplastic composite article comprising a porous core layer comprising a plurality of reinforcing fibers, a lofting agent and a thermoplastic material is provided. In certain instances, the article further comprises a skin layer disposed on the core layer and an adhesive layer between the core layer and the skin layer. In some configurations, the adhesive layer comprises a thermoplastic polymer and an effective amount of a thermosetting material to provide a post-molding peel strength between the skin layer and the post lofted core layer of at least 0.5 N/cm (in either or both of the machine direction or cross direction) as tested by DIN 53357 A dated Oct. 1, 1982.
CONDENSING ASSEMBLY, VACUUM DRYING DEVICE, AND METHOD FOR MANUFACTURING A DISPLAY SUBSTRATE
A condensation assembly includes a condensation plate and a plurality of sumps. The condensation plate includes a plate body and a plurality of protrusions on a surface of the plate body, and the plurality of protrusions are spaced apart. The plurality of sumps are disposed at a side of the plurality of protrusions away from the plate body. Each sump of the plurality of sumps is disposed opposite to at least one of the plurality of protrusions, and has an opening facing the at least one protrusion disposed opposite to the sump. There is a gap between the plurality of sumps and the condensation plate.
LIGHTWEIGHT, REDUCED DENSITY FIRE RATED GYPSUM PANELS
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.
