    摘要: Process for increasing the water retaining ability of fibrous paper stocks. The process includes knead dispersing a fibrous paper stock having a stock concentration of at least about 20% and a temperature greater than about 45null C. A treatment for the knead dispersing is at least about 10 seconds. The process further includes completing a post-treatment phase to a machine tub of a paper machine in a reaction time of no longer than about 30 minutes.

    摘要: A method and a dispersing machine for hot dispersing a highly consistent fibrous stock. The machine includes at least one stationary stator that includes a plurality of annular concentric rows of stator teeth. At least one rotating rotor is provided that includes a plurality of annular concentric rows of rotor teeth. An annular dispersing zone is formed by the stator teeth and the rotor teeth whereby the rotor teeth are adapted to rotate adjacent the stator teeth such that a distance is maintained between the stator teeth and the rotor teeth in the annular dispersion zone. An inlet is provided that allows the fibrous stock to enter the dispersion machine. A milling element is centrally arranged on the rotor. The milling element is arranged near the inlet and defines a milling zone. An annular chamber is arranged between the dispersion zone and the milling zone. At least one conduit allows a heating medium to enter the annular chamber. At least one rotatable annular centrifugal row of teeth is arranged between the milling element and the annular chamber. The method includes transporting the fibrous stock via the inlet to the milling zone, rotating the milling element to subject the fibrous stock to milling, allowing the fibrous stock to pass by the at least one rotatable annular centrifugal row of teeth, subjecting the fibrous stock to the heating medium in the annular chamber, and moving the fibrous stock through the dispersion zone.

    摘要: Process and apparatus for dispersing fibrous paper stock that includes delivering an aqueous fibrous paper stock, pressing some water out of the aqueous fibrous paper stock to form a highly consistent coarse fibrous paper stock, and introducing the highly consistent coarse fibrous stock into an effective area of a mallet roll having circulating mallets which cooperate with fixed peripheral impact sections. In this manner, the highly consistent coarse fibrous stock is loosened and distributed. The process also includes transporting the highly consistent fibrous paper stock into a dispersing machine, and dispersing the highly consistent fibrous paper stock in a dispersing machine.
