摘要:
The present invention is directed to a process for depositing at least one layer (3) based on tungsten and/or on molybdenum by chemical vapor deposition on a non-conductive substrate (1), such as glass, ceramic, glass-ceramic, or polymer, which includes providing at least one tungsten- and/or molybdenum-containing precursor in the form of a metal halide and/or of an organometallic compound, and at least one reducing agent, such as hydrogen or silane, to form the at least one metal layer. The present invention also relates to the substrate obtained by the preceding process and its applications, especially for producing a glazing, mirrors, or emissive screens.

A transparent glass substrate (1, 1null, 1null) coated with one or more thin layers (6, 16, 28) is disclosed, wherein the thin layer most distant from the glass substrate is a composition comprising silicon nitride, carbonitride, oxynitride or oxycarbonitride, said thin layer most distant from the glass substrate being covered by a second layer (7, 17) which protects against high-temperature corrosion. --
摘要:
A laminated safety glass windscreen, which can also be used as a reflector in a HUD system, comprises at least first and second panes and a thermoplastic intermediate layer which joins these panes together. The cross-section of the intermediate layer is in the shape of a wedge, decreasing in thickness from top to bottom. The thermoplastic intermediate layer may be composed of two sheets, one of which is provided with a colored filtering strip and has a wedged cross-section conditioned by the appearance of this filtering strip. The other sheet has a wedged cross-section such that the two sheets together have the prescribed convergence angle for using the windscreen as a reflector.
摘要:
The invention relates to a method of processing an electrochemical device having at least one carrier substrate (1) provided with a stack (2) of functional layers, including at least one electrochemically active layer (4) which is capable of reversibly and simultaneously inserting ions and electrons and is arranged between two electroconductive layers, in particular a device of the electrochromic type. The processing consists in locally inhibiting the functionality of at least one of the functional layers, with the exception of one of the electroconductive layers (3, 8), so as to delimit an inactive peripheral region in the stack (2).
摘要:
A glazing assembly is provided made of at least one transparent substrate having a stack thereon that includes an alternation of n functional layers and nnull1 coatings, wherein the functional layers have reflection properties in the infrared and/or solar radiation and where nnull1 and where, in order to maintain the quality of the stack when the substrate is subjected to a heat treatment step, at least one of the following must be satisfied: the coating placed on top of at least one of the functional layers includes at least one barrier layer providing a barrier to at least oxygen and water; and at least one absorbent or stabilizing layer made of a material capable of absorbing or stabilizing the consituent material of the functional layer forms a part of either the coating placed on top of the functional layer and under the barrier layer or the coating placed beneath the functional layer; and a method for production of the glazing assembly.
摘要:
The present document describes a process for manufacturing a pane of laminated glass without recourse to an autoclave. The pack of layers are composed of stacked layers (6, 7, 8), is raised to the softening temperature of the thermoplastic interlayer of the pack of layers in a preheat channel (1). The preheated pack of layers is put under vacuum in a vacuum assembly station (2) for the purpose of extracting the gas from the spaces separating the layers (6, 7, 8). After the gas has been extracted, the edge of the pack of layers, which is held under vacuum, is mechanically compressed inside the vacuum box and is thus sealed. Finally, the pack of layers is brought to atmospheric pressure and its temperature further increased in a postheat channel (4).
摘要:
A process for laminating multi-layer pre-forms into laminated glazing assemblies is provided. The pre-forms are first subjected to a vacuum in an inlet lock. Then, the pre-forms are heated to an assembly or bonding temperature in a heating chamber, while still being subjected to vacuum. Next, the pre-forms are pressed using pressing pieces in a pressing chamber, which is also subjected to vacuum. A greater pressure is exerted along the edges of the laminated glazing assemblies so as to bond the edges, preferably by using membranes. In an outlet lock which follows the pressing chamber, the laminated glazing assemblies are again vented to atmospheric pressure. An apparatus suitable for carrying out the process is also provided. The apparatus has chambers which are connected together by conveyors so as to achieve a quasi-continuous flow of material.
摘要:
The subject of the invention is a process for manufacturing compounds based on one or more silicates of alkali metals, such as Na and K and/or alkaline earth metals such as Ca, Mg, and/or on rare earths, such as Ce, optionally in the form of mixed silicates which combine alkaline-earth metals, such a Ca, with the alkali metal(s) and the rare earth(s), by conversion of silica and of halides, especially of one or more chlorides, or sulfate or nitrate, of the said alkali metals and/or of the said rare earths and/or of the said alkaline-earth metals, such as NaCl, KCl or CeCl4. The heat needed for the conversion is supplied, at least partly, by one or more submerged burners. The subject of the invention is also an apparatus for carrying out the process and for its use.
