摘要:
A plant (20) comprising at least one mixing machine (23), a rolling surface (21), a conveying surface (22), at least one first pair of rolling rollers (24A), in which the rollers are rotatably arranged parallel to each other at a pre-selected distance and at least one of them is motorized, and means (25) for conveying a paste formed in said mixing machine (23) into the vicinity of said first pair of rolling rollers (24A).
摘要:
A permeable, resin-bonded composition is described, which finds utility as a porous element in a gas-injection nozzle. The permeable composition is notably useful in a canless, resin-bonded, gas-injection nozzle, characterized by an impermeable, resin-bonded composition replaces the metal can. Advantageously, the resin-bonded compositions include an oxygen getter for scrubbing oxygen before the oxygen can reach the molten steel. A method of manufacturing the nozzle is described and includes copressing a standard, resin-bonded composition around the permeable, resin-bonded composition. The pressed piece may be cured at temperatures below about 800 °C.

A first alumina honeycomb structure, characterized in that it has an impurity content of 2 wt % or less and contains alumina as a primary component; and a second alumina honeycomb structure, characterized in that it contains alumina as a primary component in an amount of 98 wt % or more, the Na-containing compounds in an amount of 0.02 wt% to 1.0 wt % in terms of Na2O, the balance of the structure being impurities.
摘要:
The invention concerns in particular a composition designed for making an article comprising one or more superimposed layers having each a thickness less than 5 centimeters, containing a hydraulic binder and at least one compound selected among an organic compound including at least two hydrophilic functions and a hydrophobic chain, and a polyamide oligomer. The use of said additives in the presence of hydraulic binder enables manufacture of articles and coatings having good protection against water uptake, satisfactory resistance to humidity and good mechanical properties such as rupture strength.

摘要:
A composite panel having front and back faces, the panel comprising facing reinforcement, backing reinforcement and matrix material binding to the facing and backing reinforcements, the facing and backing reinforcements each independently comprising (i) one or more reinforcing sheets and/or (ii) one or more generally planar arrays of longitudinally arranged, spaced apart, reinforcing rods which are interconnected by means for resisting increase of the spacing distance between adjacent rods, at least one rod array (ii) being present in the facing and/or backing reinforcement wherein the means for resisting increase of the spacing distance between adjacent rods is transverse filamentary interlacing of rods in the array, the facing reinforcement being located on or embedded in matrix material adjacent to the front face of the panel, the backing reinforcement being located in a plane or planes substantially parallel to the plane or planes of the facing reinforcement, and being substantially coextensive therewith, and spaced therefrom by matrix material.

A composite panel having front and back faces, the panel comprising facing reinforcement, backing reinforcement and matrix material binding to the facing and backing reinforcements, the facing and backing reinforcements each independently comprising one or more reinforcing sheets, the facing reinforcement being located on or embedded in matrix material adjacent to the front face of the panel, the backing reinforcement being located in a plane or planes substantially parallel to the plane or planes of the facing reinforcement, and being substantially coextensive therewith, and spaced therefrom by matrix material, the facing and backing reinforcements being interconnected to resist out-of-plane relative movement. The reinforced composite panel is useful as a barrier element for shielding structures, equipment and personnel from blast and/or ballistic impact damage.
摘要:
An elongated honeycomb filter (F100) is formed from a sintered porous ceramic body, and has a ratio L/S between a filter length L in a flow direction of a processed fluid and a filter cross-section S in a direction perpendicular to the flow direction of 0.06mm/mm 2 to 0.75mm/mm 2 . Also disclosed is a filter assembly comprising a plurality of filters, and an exhaust gas purification apparatus including the filter assembly.
