Unique insulation articles including corrosion inhibitors and methods of producing the same are disclosed. One exemplary embodiment is an article of manufacture comprising an insulation mat comprising a cured combination of a plurality of randomly oriented fibers and a binder, the insulation mat extending between a first surface and a second surface, a veil attached to the first surface, the veil structured to inhibit physical movement of the cured combination through the veil, a metal sheet attached to the second surface by a water-containing adhesive contacting the metal sheet and the second surface, and a corrosion inhibitor composition deposited on the cured combination of the insulation mat, the corrosion inhibitor composition being effective to modify toward neutral a pH of the cured combination in contact with water from the water-containing adhesive.

This application relates to making magnesium oxychloride boards. A magnesium oxychloride slurry is mixed by directing magnesium chloride, magnesium oxide, at least one phosphate, at least one inorganic salt, and water into a mixer and mixing these ingredients together to form a slurry. At least one filler is then mixed with the slurry. The slurry is directed to a mold. The mold is formed with the slurry to form a magnesium oxychloride board. The magnesium oxychloride board is then cured.

Laterally-coalesced foam slabs and methods and apparatus, including foaming dies, for making and using such foam slabs.

Methods of and systems for forming pipe insulation are disclosed. The pipe insulation has properties that are non-homogenous through its thickness.

A two layer and/or a three-layer device is disclosed that allows samples therein to remain at a warmer or a colder temperature than would be ordinarily possible without the use of the two or three-layer device. The two-layer device contains an interior layer that comprises the sample, and a middle or intermediate layer that comprises chemical species that undergoes an exothermic or endothermic reaction. The three layer device further has an outer layer that contains an insulating layer. When the three layer device is used for samples, the temperature of the sample can remain at a temperature around 11° C. or less for at least about 5.5 to 6 hours.

A heat-insulation sheet includes a first silica xerogel layer, a second silica xerogel layer, and a composite layer. The first silica xerogel layer includes a first silica xerogel, and the second silica xerogel layer includes a second silica xerogel. The composite layer is located between the first silica xerogel layer and the second silica xerogel layer, and includes at least one type of unwoven fabric fibers, and a third silica xerogel. The third silica xerogel is located in a spatial volume of the unwoven fabric fibers.

A heat insulation material includes a laminate obtained by stacking fiber layers that include heat-resistant fibers, the fiber layers being bound with a thermosetting resin, wherein the laminate does not include a thermoplastic resin that has a heat-resistant temperature lower than that of the thermosetting resin, or includes only a small amount of a thermoplastic resin that has a heat-resistant temperature lower than that of the thermosetting resin.

A passivating flexible insulation blanket positionable about a pipe includes an insulation core, an enclosing fabric, and a non-consumable passivator. The insulation core is substantially hydrophobic and includes a microporous material. The enclosing fabric fully encapsulates the insulation core to form a capsule or pouch about the insulation core. The non-consumable passivator is non-consumable such that there is no appreciable change to a mass of the non-consumable passivator after an extended time of activation. The non-consumable passivator is deposited into the insulation core and has a composition soluble in water. The non-consumable passivator includes a leachable component that leaches from the insulation core and is capable of neutralizing acidic components. The leachable component is water soluble and is capable of reacting with a surface of the pipe to form a protective coating on the pipe to aid in inhibiting corrosion formation on the surface of the pipe.

The present invention describes various methods for manufacturing gel composite sheets using segmented fiber or foam reinforcements and gel precursors. Additionally, rigid panels manufactured from the resulting gel composites are also described. The gel composites are relatively flexible enough to be wound and when unwound, can be stretched flat and made into rigid panels using adhesives.

A bionic nested structure fiber composite material includes a first fiber resin layer and a second fiber resin layer which are arranged in parallel, the first fiber resin layer and the second fiber resin layer are formed by a fiber bundle infiltrated with resin, and a bonded fiber unit is arranged between the first fiber resin layer and the second fiber resin layer, the bonded fiber unit are evenly distributed in a radial direction and a weft direction, the bonded fiber unit includes an inner core layer bonded fiber bundle, a middle core layer bonded fiber bundle and an outer core layer bonded fiber bundle, and the bonded fiber unit is performed 3D integrated layer-by-layer inner and outer nesting-and-weaving to form bionic nested structure.
