  • Publication number: 20250163838
    Abstract: An exhaust purification apparatus capable of improving stirring property of urea water and properly cooling an injection device is provided. The exhaust purification apparatus that purifies nitrogen oxides in exhaust gas includes an exhaust pipe that causes exhaust gas discharged from an engine to flow, a catalyst reactor (catalyst) provided in the exhaust pipe to reduce the nitrogen oxides in the exhaust gas, a through pipe provided in such a way as to penetrate the exhaust pipe, and an injection device provided inside the through pipe to inject a reducing agent for reducing exhaust gas into the exhaust pipe.

  • Patent number: 8372517
    Abstract: An acrylic thermoplastic resin composition is obtained by melt-kneading a methacrylic resin (A) and a polyvinyl acetal resin (B) at a resin temperature of not less than 140° C. while applying shear at a shear rate of 100 sec?1 or more, and then cooling the kneaded product to not more than 120° C. In the acrylic thermoplastic resin composition, at least the methacrylic resin (A) forms a continuous phase, and among glass transition temperatures of the acrylic thermoplastic resin composition, a glass transition temperature TgA P ascribed to the methacrylic resin (A) indicates a value between a glass transition temperature (TgA) of the methacrylic resin (A) alone and a glass transition temperature (TgB) of the polyvinyl acetal resin (B) alone. A film- or sheet-like molded article is obtained by molding the resin composition. An acrylic resin composite is obtained by laying a layer of metal and/or metal oxide on at least one side of the acrylic resin molded article.
