    摘要: An extrusion die for producing multichanneled structures from an extrudable material. The die is composed of a series of pins that correspond to the shape of the channels in the structure. At one end of the pins, the area between the pins is open to define a discharge zone having the shape of the structure. At their opposite ends, the pins are connected about adjacent corners by a series of webs. Slots bordered by the pins and the webs define a series of feed passages that communicate with the discharge zone at areas of reduced width between adjacent pins.

    摘要: The present invention relates to a method of preparing an alumina hydrosol from an aluminum sulfate solution. The subject method comprises the steps of admixing a stoichiometric amount of a metal selected from the group consisting of calcium, strontium and/or barium in the form of a mixture of a hydrated chloride metal salt and a metal hydroxide with an aqueous aluminum sulfate solution, filtering the resulting metal sulfate precipitate from the above admixture, recovering a substantially sulfur-free aluminum-containing filtrate solution, admixing aluminum metal with the filtrate solution, and digesting the aluminum metal at digestion conditions with the filtrate solution to form an alumina hydrosol possessing the desired Al:Cl weight ratio.

    摘要: A honeycombed structure is extruded and wash coat applied to the interior channels of the structure before the honeycomb structure is separated from the die in which it is formed. This method produces the honeycombed structure using a die that includes a die body having an inlet and an outlet side, a plurality of parallel pins defined by the body that correspond to the shape of the channels in the honeycombed structure, and a discharge zone that communicates directly with the outlet side of the die and is defined by the open area between the pins. The extrudable material enters the discharge zone from a series of feed passages defined by the pins and a plurality of webs that interconnect the pins. Each pin has an interior duct with an opening at the end of each pin. A series of internal passages in the die body receive fluid from one or more ports on the periphery of the die and distribute the fluid to the ducts. Spraying the wash coat from the ends of the pins eliminates the need for a separate wash coat step after the honeycombed structure has been formed. In addition, wash coat is continually applied to the interior walls of the channel by the duct as the channel passes the end of the pin so that the entire length of the channel is covered with wash coat. This invention can be used in a wide variety of die configurations, but is especially suited for a die having segmented slots for feed passages and square channel forming pins defined in part by the segmented slots.
