摘要:
A machine and method for the surface treatment of a base ceramic article having at least one surface to be treated; wherein a first printing assembly applies a first layer of adhesive material on at least part of the surface to be treated; a first depositing assembly deposits a second layer of powder material on at least part of the first layer so as to remain stuck to the first layer; and a second printing assembly applies a third layer, which comprises (in particular, consisting of) an adhesive and/or covering material, on at least part of the second layer.
摘要:
A method and apparatus to treat a dried unfired article comprising a ceramic precursor composition substantially held together by a binder, to be resistant to binder soluble solvent based processing. The method includes depositing a fluid on the article surface, and polymerizing the deposited fluid to form a polymer thin layer on the surface. The fluid may be an aerosol, a vapor, a fog, a mist, a smoke, or combinations thereof. An apparatus to perform the method and an article resistant to binder soluble solvent based processing are also provided. The article can be an unfired honeycomb body that includes a dried composition of ceramic precursor substantially held together by a binder and a layer disposed on a surface of the unfired honeycomb body. The surface to be exposed in the green state to a binder soluble solvent and the layer protects the binder from solubilization by the solvent.

Embodiments of the invention comprise a method of making a construction board (also known as wallboard) and a device for making same. The resulting construction board is formed by mixing of at least magnesium oxide, magnesium chloride, and a binding agent into a slurry, adding particulized solid material while funneling the slurry, and extruding the slurry comprising the particulized solid material.

A method is disclosed of producing ballast pavers for use in a roof system. A concrete mixture may be provided. The concrete mixture may be shaped into an uncured paver including a top surface. A reflective coating may be applied to the top surface. The uncured paver may be heated in a kiln to cure the concrete mixture. The reflective coating being substantially cured upon removal from the kiln.

Processes for coating concrete bricks with exposed surfaces having sharply delineated portions of contrasting color and/or texture by periodically and regularly forming atomized particles of a viscous cementitious slurry and directing same on to portions of surfaces of each of a plurality of green concrete bricks in groups located stationary in regular fashion for a brief period and thereafter firing the thus coated uncured brick. The processes include steps for rapidly and/or sequentially varying the colors applied to the different groups of bricks during successive cycles of coating the successively treated different groups of such brick.

Provided are a method of manufacturing a ceramic article in which the improvement of mechanical strength, wear resistance, and machinability is achieved using a direct modeling system, and a ceramic article. The manufacturing method includes the steps of: (i) arranging powder containing ceramics as a main component on a base; (ii) irradiating a part or an entirety of the arranged powder with an energy beam to melt and solidify the powder, to thereby obtain an intermediate modeled article; (iii) causing the modeled article to absorb a metal component-containing liquid to impregnate the modeled article therewith; and (iv) subjecting the modeled article having absorbed the metal component-containing liquid to heat treatment.
摘要:
The present invention describes a ceramic tile with raised patterns and a method for producing raised patterns on a ceramic tile that comprises printing one ink followed by printing a second ink characterised by being insoluble in the previous ink, so as to form a raised pattern with a height of 50 micrometres to 500 micrometres. Finally, the ceramic tile is fired at a maximum temperature of 850° C. to 1300° C.
