    Abstract: The method for flame coating tubular elements provides for arranging a said tubular element (2) to be coated at a coating station, providing an applicator unit (3), operating in the coating station, in an inactive configuration, spaced from the tubular element (2), the applicator unit (3) carrying at least one thermoplastic powders flame applicator device (4) and being alternatively operable between the inactive configuration and an active configuration, approached radially to the tubular element (2). After having brought the applicator unit (3) towards the tubular element (2), the method provides for operating the same unit (3) in the active configuration, so as to peripherally engage the element (2) itself. The applicator device (4) is turned on, the thermoplastic powders are fed and the applicator device (4) is operated in motion around and/or along the tubular element (2) so as to flame coating it with a controlled flow of thermoplastic powders.

    Abstract: The present invention provides a method for manufacturing a decorative construction plate, the method including subjecting a metal siding material including: a metallic substrate on which a recess-projection pattern having a height difference of 0.5 mm or more is formed and on which an ink receiving layer formed from a resin composition is provided; a core material; and a back-side material, to flame treatment by exposing the metal siding material to flame with an output of 250 kJ/h to 12000 kJ/h per 10-mm width of a flame port of a burner so that the surface temperature of the substrate does not exceed 300° C., followed by performing inkjet printing using an active ray curable ink.

    Abstract: The purpose of the present invention is to provide a method for manufacturing a painted metal plate which is resistant to surface stain due to rain streaks. The painted metal plate manufacturing method comprises: a step of forming a coating film on a surface of a metal plate, the coating film having an arithmetic mean roughness Ra of 0.3 to 3.0 μm as calculated according to JIS B0601:2013, and a surface Si atomic concentration of less than 1.0 atm % as measured by X-ray electron spectroscopy using an AlKα beam as an X-ray source; and a step of subjecting the coating film to flame processing at 30 to 1000 kJ/m2.
