摘要:
Hydrophilic, pulverulent thermal-insulation material containing from 5 to 30% by weight, based on the hydrophilic, pulverulent thermal-insulation material, of an IR opacifier and from 70 to 95% by weight, based on the hydrophilic, pulverulent thermal-insulation material, of aggregated particles of a hydrophilic silica having a BET surface area of 200-600 m 2 /g and a thickening of at least 5000 mPas, wherein the thickening is determined in a dispersion of the silica in an unsaturated polyester resin, process for the production thereof, and use for producing a thermal-insulation sheet or thermal- insulation granules.

Disclosed is a building board with increased heat and fire resistance. Boards constructed in accordance with this disclosure have lower densities while at the same time containing larger amounts of anti-shrinkage materials. In one embodiment, a board was constructed with a density of less than 1,750 lbs/msf while at the same time including anti-shrinkage additives in amounts greater than 14% by weight of the core material. The inventors have discovered that beneficial, and heretofore unexpected, levels of fire resistance can be achieved by using increased amounts of anti-shrinkage additives in lower density building boards.

A method for continuously forming gypsum-based panels of high fixing strength comprises the steps of: • forming a mixture comprising stucco, non-pregelatinized migratory starch, glass fibre, fluidizer and water; • casting the mixture in a continuous band; • maintaining the band under conditions sufficient for the stucco to form an interlocking matrix of set gypsum; • cutting the band to form one or more wet panel precursors; and • drying the wet panel precursor to form one or more gypsum-based panels. • The weight ratio of water to stucco in the mixture is less than 0.7; • the stucco is present in the mixture in an amount of over 60 wt% relative to the total solids content of the mixture; • the starch is present in the mixture in an amount of over 3 wt% relative to the the stucco; • the glass fibre is present in the mixture in an amount of over 1 wt% relative to the stucco; • the fluidizer is is present in the mixture in an amount of at least 0,1 wt% relative to the stucco; and the density of the gypsum-based panel is greater than 700 kg/m.

Verfahren zur Herstellung eines mit Ammoniak behandelten, hydrophilen Wärmedämmformkörpers, bei dem man einen hydrophile Kieselsäure aufweisenden Wärmedämmformkörper mit Ammoniak behandelt, bei dem man den Wärmedämmformkörper in eine Kammer einbringt und solange gasförmigen Ammoniak zuführt, bis die Druckdifferenz Δp ≥ 20 mbar beträgt. Verfahren zur Herstellung eines hydrophobe Kieselsäure enthaltenden Wärmedämmformkörpers, bei dem man den mit Ammoniak behandelten, hydrophilen Wärmedämmformkörper mit einer Organosiliciumverbindung behandelt.
摘要:
The present invention relates to nanoparticles and their use to form nanocomposite material, in particular bionanocomposite material, specifically wherein the nanoparticles are formed using plant virus attached to a scaffold of cellulosic material and / or cellulose derived materials, in particular wherein said cellulosic material further comprises plant cell components, for example hemicellulose, pectin, protein or combinations thereof.
摘要:
A partition is adapted to support a fixture and has a front surface to which the fixture may be affixed and a back surface that faces away from the fixture. The partition comprises a plasterboard and a reinforcing board, the reinforcing board being located between the plasterboard and the front surface, and the plasterboard comprising at least 1 wt% fibre and at least 1 wt% polymeric additive.
