摘要： A method for making a three-dimensional object by means of layer-wise application and selective solidification of a pulverulent building material The method includes applying a layer of the pulverulent building material onto a build area by an application device The application device includes a recoating unit movable across the build area in an application direction. The method further includes solidification of the applied powder layer at positions corresponding to a cross-section of the object to be made, and repeating the steps of applying and selective solidification until the object is completed. The pulverulent building material to be applied onto the build area is heated locally by a radiant heater before being applied.

摘要： Sintered product having a relative density of greater than 90%, with, to more than 80% of the volume thereof, a stack of flat ceramic platelets, the assembly of the platelets having a mean thickness of less than 3 μm, having a width of greater than 50 mm, and including more than 20% of alumina, as a percentage on the basis of the weight of the product. The width of the product is the largest dimension measured in the plane in which the length of the product is measured, along a direction perpendicular to the direction of the length. The length of the product is the largest dimension thereof in a plane parallel to the general plane in which the platelets extend.

摘要： A concrete composition and method include a portion of fine aggregate bearing a coating of a polymer or an admixture, which may be a continuous coating layer or a layer of powdered, discrete particles embedded in a binder. The polymeric coating may be an admixture in powdered form, a super absorbent polymer (insoluble in water, but absorbing water), or another polymer such as the acrylamides, co-polymers thereof, polyacrylamides, or the like (soluble in water). The coating absorbs water, but particles are too small to form significant voids. Water is absorbed into the concrete mix in far greater proportions (e.g. w/c ratio over 0.5) improving workability, doubling workability time, and improving ultimate compressive stress (strength).

摘要： 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.

摘要： Methods for improved ceramics component casting. One such method may include vacuuming a ceramic-based slurry mixture and/or vacuuming a component mold. The vacuuming of the ceramic-based slurry mixture and the component mold may be to remove air bubbles from the respective elements. More specifically, the vacuuming may remove air bubbles from the ceramic-based slurry mixture and from a cavity of the component mold, respectively. The method may also include disposing the ceramic-based slurry mixture into the cavity of the component mold, and continuously vacuuming the cavity of the component mold including the ceramic-based slurry mixture for a predetermined time to remove any additional air bubbles included in the ceramic-based slurry mixture. Finally, the method may include forming a ceramic component within the continuously vacuumed cavity of the component mold over the duration of the predetermined time. The ceramic component formed from the ceramic-based slurry mixture.

摘要： A manufacturing method includes: a dry mixing step of dry mixing a raw material by batch processing; a wet mixing step of adding liquid to a dry mixture obtained at the dry mixing step, the liquid including at least one type of water, surfactant, lubricant and plasticizer, while wet mixing; a kneading step of kneading a wet mixture obtained at the wet mixing step; and a forming step of extruding a kneaded mixture (forming raw material) obtained at the kneading step to make a ceramic formed body. In the kneading step, the liquid is further added during kneading of the wet mixture.
