Patent number: 11369927Abstract: A method for reducing gel in a polymer kneaded compound flowing in a polymer flow duct includes flowing a polymer kneaded compound in a polymer flow duct to a gel reduction mechanism including a gel reduction member having one or more through holes defining a squeezing flow path having a flow path cross-sectional area smaller than the polymer flow duct. The squeeze ratio S1/S2 of the squeezing flow path is 25 to 177.8, where S1 is a flow path cross-sectional area of the polymer flow duct and S2 is a sum total of flow path cross-sectional area of the squeezing flow path, to generate an extensional flow in the kneaded compound.Type: GrantFiled: November 9, 2018Date of Patent: June 28, 2022Assignee: Kobe Steel, Ltd.Inventors: Yoshinori Kuroda, Tsugushi Fukui, Kazuo Yamaguchi, Takaya Uda, Katsunori Takahashi, Sayaka Yamada

Patent number: 10899040Abstract: A continuous mixer includes a barrel with a hollow interior, and a pair of mixing rotors housed in the barrel and that rotate in mutually different directions, each mixing rotor including a mixing portion with plural mixing flights formed about an axial center of the mixing rotor and projecting radially outward. The mixing rotors have a center distance therebetween smaller than a rotation outer diameter of each of the respective mixing flights. An inter-rotor clearance, which is the smallest clearance between the mixing portions at each rotation phase of the mixing rotors in a cross section perpendicular to axial directions of the both mixing rotors, has a dimension allowing an extensional flow to be generated in a material passing through the inter-rotor clearance. The continuous mixer can reliably and efficiently mix a material having a large viscosity difference between a dispersed phase and a matrix phase.Type: GrantFiled: July 27, 2011Date of Patent: January 26, 2021Assignee: Kobe Steel, Ltd.Inventors: Kazuo Yamaguchi, Takaya Uda, Yoshinori Kuroda, Tsugushi Fukui
