Microwave reflective panel, elements comprising such a panel, and method for obtaining them
A panel for glazing including a rigid support, substantially transparent to radiation in the visible range, and including at least one surface, including a periphery, and one or more edges, the panel includes a metallic fabric stretched over the at least one surface. Also, a glazing including such a panel, a sealing device of a heat treatment chamber including such a glazing, a heat treatment device using microwaves including such devices, and methods for producing the panel, the glazing, the sealing device and the heat treatment device.
The present invention relates to a method for obtaining an enamelled panel (1) having a silky feel and a matt appearance, comprising the steps of taking a rigid support (2) comprising at least one surface (3, 4), taking or preparing at least one enamel composition comprising a vitrifiable material, and silica particles, depositing the enamel composition on all or part of said at least one surface (3, 4) of the support (2), in order to form an enamel layer (5), having an upper face (6) from which the silica particles protrude, forming a surface roughness made of bumps and recesses, drying the enamel layer (5), vitrifying the enamel layer (5) through the action of heat, and chemically surfacing the upper surface (6).
The present invention relates to a method for producing a decorative panel (1), comprising the steps of taking a substrate (2) made of glass, comprising at least one first surface (4 or 5), preferably also a second surface (4 or 5), opposite said first surface (4 or 5), and optionally also at least one first edge (6, 7, 8, 9); taking one or more solid metal films (3), made of one or more metals or metal alloys; taking a laser source (13) capable of generating a pulsed laser beam (12); directly plating at least said first surface (4 or 5), by arranging said metal film or films (3) facing, at a distance or in contact, said at least first surface (3 or 4) between the substrate (2) and the laser source (13), and by applying said laser beam (12) to the metal film(s) (3) in order to transfer the metal(s) or metal alloy(s) directly onto the at least first surface (4 or 5), according to a given pattern, in order to form a coating comprising a metal layer (14) covering all or part of the at least first surface (4 or 5), the metal layer (14) comprising an upper surface (15); and surfacing said upper surface (15) of the metal coating (14) in order to modify the surface condition thereof, so as to give it the visual aspect and/or the feel of a metal that has been machined.

A method is provided for corner contouring of flat glass substrates in a continuous feed-through process by a contouring tool. The method includes the steps of: synchronization of the movement of the contouring tool to the continuous feed-through movement of the flat glass substrate, contouring of a corner of the flat glass substrate, wherein a relative movement between the contouring tool and the flat glass substrate is performed so as to overlap the continuous feed-through movement.
