摘要:
A method of producing pulp moldings having a paper-making process comprising the steps of assembling split mold halves (11, 12) having suction passageways (14) to form a paper-making mold (10), feeding pulp slurry of predetermined set feed concentration into the cavity (13) in the paper-making mold (10), and sucking the pulp slurry through the suction passageways (14) to form a pulp layer (15) on the inner surface of the paper-making mold (10), wherein the concentration of the pulp slurry in the cavity (13) in the initial and/or final period of formation of the pulp layer (15) in the paper-making process is lower than the above-mentioned set feed concentration of the pulp slurry.
摘要:
A process for producing a pulp molded article comprising inserting a hollow inflatable pressing member 81 which has been made small so as to have smaller cross-sectional contour into a cavity 4 of a mold 1 in which a pulp layer 7 has been formed, and feeding a pressurizing fluid into the inserted pressing member 81 to inflate the pressing member 81 thereby to press the pulp layer 7 onto the inner wall of the cavity 4.
摘要:
A method of producing a pulp molded article. The method feeds a pulp slurry to a cavity of a papermaking mold having a prescribed cavity shape to form a pulp preform including a main part having an opening and a separable part having a flange and connected to an edge of the opening. A pressing member is inserted into the preform, the pressing member is expanded to press the preform toward the papermaking surface, the preform is removed from the papermaking mold, and then the preform is cut at a joint between the separable part and the main part.

An element made by papermaking for use in the production of a casting cast which comprises an organic fiber, an inorganic fiber, and a binder. The contents of the organic fiber, the inorganic fiber, and the binder are preferably 10 to 70 parts by weight, 1 to 80 parts by weight, and 10 to 85 parts by weight, respectively. The binder is preferably an organic binder. The organic fiber is preferably pulp fiber.
摘要:
A part for casting obtained by converting base paper for paper tubing into a tube and containing an organic fiber, an inorganic fiber, and a binder. The part is preferably obtained by winding the base paper into tubing. The part preferably contains 10 to 70 parts by weight of the organic fiber, 1 to 80 parts by weight of the inorganic fiber, 10 to 85 parts by weight of the binder. The organic fiber is preferably pulp fiber.
摘要:
A method of producing a pulp molded article comprising a papermaking step in which a pulp slurry is fed to the surface of a papermaking mold having suction paths, and water contained in the pulp slurry is sucked through the suction paths whereby the pulp is deposited on the surface to form a wet preform, and a dewatering step in which the wet preform is dewatered, wherein the temperature of the fed pulp slurry is raised while the pulp is being deposited on the surface.

摘要:
An electrochromic dimming device is provided. The electrochromic dimming device includes an electrochromic element, a color development power source, a color discharge powder source, and a variable resistance. The color development power source supplies electric power to the electrochromic element when the electrochromic element develops color. The color discharge powder source supplies electric power to the electrochromic element when the electrochromic element discharges color. The variable resistance is disposed on a first current path without being disposed on a second current path. The first current path is formed from the color development power source through a ground via the electrochromic element, and the second current path is formed from the color discharge power source to the ground via the electrochromic element.
摘要:
An apparatus divides a photographed image of a sheet-like inspection object into blocks each of which has a size of a predetermined number of pixels by a predetermined number of pixels, calculates a longitudinal variance based on pixel values in a longitudinal direction in each block and a lateral variance based on pixel values in a lateral direction in the block, determines whether the block is a defect candidate using the longitudinal variance and the lateral variance as sheet-like inspection object defect determination evaluation values, and determines, based on one of a length and an area of the blocks determined as the defect candidates, whether the sheet-like inspection object has defect.
