摘要:
A molded article having a small difference in thermal conductivities between a central section and a section located at an outer peripheral surface side; and a method for producing the same; wherein, a plate-shaped molded article includes an aluminum-silicon carbide composited section in which a metal including aluminum was impregnated into a silicon carbide porous body, wherein a difference in the densities, by Archimedes' principle, of a central section of the aluminum-silicon carbide composited section and of at least a portion of an outer side section located further toward the outside peripheral surface side than the central section is 3% or less.
摘要:
A method for realising a ceramic slab, comprising the following steps: arranging on a first deposition plane (50) a decorated layer (L2) provided with a decoration (200), gradually depositing the decorated soft layer (L2) from a head (H) to a tail (T); gradually transferring the soft layer (L2) by deposition from the first deposition plane (50) to a second deposition plane (83), placed at a lower height than the first deposition plane (50), starting from the tail (T) of the second soft layer (L2), gradually realising a second layer (L3) on the second deposition plane (83).
摘要:
A method of preparing stackable block structures from raw concrete mixes and block structures prepared in accordance with the method, wherein the process utilizes a mold box configured to form the block on its side surface. The mold box is arranged to travel along the surface of a moving conveyor belt, with the box having an open top, an open bottom, and lateral side panels supported on the conveyor belt surface, and with the panels having core bar receiving openings formed therein. The core bars are introduced and removed from the mold box along an axis which is parallel to the surface of the core bars and to the motion axis of the conveyor belt, and with the core bars configuring one of the two opposed side surfaces of the stackable block. A reciprocating top shoe arranged for reciprocatory up and down motion engages and configures the top surface of the raw concrete mix held within the walls of the mold box.
摘要:
The invention relates to a method for the mass decoration of ceramic products, comprising the following steps: spreading, superposed on one another, a layer (L) of granular or powder material and a decorative layer (3) on a support surface (2); transferring the layer (L) from the support surface (2) to an accumulation belt (T1), contiguous and aligned to the support surface (2), which is located at a lower height than the support surface (2), wherein the accumulation belt (T1) is mobile in advancement at a speed that is different from the advancement speed of the support surface (2), so that a variation in the thickness and longitudinal extension of the layer (L) is produced; pressing the layer (L) and the decorative layer (3).
摘要:
The invention relates to a method and a system (10) for forming pressed articles by pressing powder or granules, the system comprising the following apparatuses: a powder discharge assembly (12); a no-cavity press assembly (20) including: an bottom plate (22) that is the same size or greater than the pressed articles, a constraining means to isolate a portion of powder, and a top punch (24); and a conveyor (14) to transport the powder and/or pressed articles.
摘要:
An article comprising a hydrated matrix containing 100 parts by weight of cement and around 80-120 and preferably around 100 parts by weight of sand with a grain size of less than 1 mm, and alkali-resistant reinforcing glass fibres in a proportion of around 3-4 wt %, preferably 3.5 wt %, relative to the hydrated matrix. The article, which has a density no greater than 1.85, may be used as a covering panel for buildings, and particularly as an imitation slate covering panel.
