摘要:
The present invention concerns a device (10) for the surface treatment of a substrate (1) by dielectric barrier discharge that enables the generation of a cold filamentary plasma at atmospheric pressure, comprising a reaction chamber, in which are positioned means for supporting and/or moving the substrate (2) and at least two electrodes (3, 4) arranged in parallel on either side of the means for supporting and/or moving the substrate (2), of which one electrode (3) is intended to be brought to high voltage and a counter-electrode (4) to be earthed. It is characterised in that the counter-electrode (4) has a width (l ce ) and a length (L ce ) that are respectively smaller than the width (l e ) and the length (L e ) of the electrode (3), and in that the counter-electrode (4) is positioned so that it is enclosed in an orthogonal projection (5) of the electrode (3) on a plane containing the counter-electrode (4). The invention also concerns a surface treatment process, in particular for layer deposition, that calls for such a device.

The present disclosure relates generally to anti-soiling compositions, methods of applying anti-soiling compositions, and equipment for applying anti-soiling compositions. In some embodiments, the present disclosure relates to a method of forming a durable coating on a glass substrate, comprising: (1) applying a coating composition to a glass substrate, the applied coating composition having a thickness of greater than 4 microns; the coating composition consisting essentially of about 0.25% to about 10% by weight of non-oxidizing nanoparticles, an acid, and water; (2) allowing the coating composition to remain on the glass substrate for at least an amount of time sufficient to permit at least some of the nanoparticles to bond to the glass substrate; (3) reducing the thickness of the coating composition to about 0.25 to 4 microns, and (4) evaporating at least some of the water to form the durable coating.
摘要:
Die Erfindung betrifft ein Verfahren zur Herstellung einer pastösen SiO 2 -Masse unter Verwendung eines SiO 2 -Schlickers, das einfache Zwischenlager- und Transportbedingungen zulässt ohne dass dadurch die Verarbeitbarkeit des Schlickers zur pastösen SiO 2 -Masse beeinträchtigt wird. Erfindungsgemäß wird dazu vorgeschlagen, dass ein homogenisierter SiO 2 -Grundschlicker einem Trocknungsschritt unter Bildung einer SiO 2 -Trockenmasse unterzogen und anschließend mittels eines Wiederbefeuchtungsschrittes zu der pastösen SiO 2 -Masse weiterverarbeitet wird, wobei der Wiederbefeuchtungsschritt die Zugabe von Flüssigkeit auf die SiO 2 -Trockenmasse unter Ausbildung einer pastösen knetbaren SiO 2 -Masse mit einem Feststoffgehalt von mehr als 85 Gew.-% umfasst. Die Erfindung betrifft weiterhin die Verwendung einer pastösen SiO 2 -Masse als Reparaturmasse.
摘要:
A chemical vapor deposition process for the deposition of a silica layer on a glass substrate is provided. The process includes providing a glass substrate. The process also includes forming a gaseous precursor mixture comprising a silane compound, oxygen, water vapor, and a radical scavenger and directing the precursor mixture toward and along the glass substrate. The mixture reacts over the glass substrate to form a silica coating thereon.
摘要:
Ein Glas (1), versehen mit einer Korrosions-Schutzschicht (2), soll insbesondere für technische Anwendungen besonders geeignet sein und durch die aufgebrachte Korrosions-Schutzschicht (2) mit vergleichsweise einfachen Mitteln besonders wirksam gegen Korrosionseffekte und insbesondere gegen unerwünschte Auslaugung geschützt sein. Dazu ist die Korrosions-Schutzschicht (2) erfindungsgemäß porös ausgeführt und weist eine Porosität, gemessen durch den Anteil des Porenvolumens am Gesamtvolumen der Schicht (2), von mindestens 30 % auf.

The invention relates to a method for producing a porous coating on a glass surface, wherein an aqueous potassium silicate solution is applied to the glass surface and a porous silicate coating is formed on said glass surface. The pH of the potassium silicate solution is controlled and the formation of the silicate coating is carried out in a process atmosphere of which the relative humidity is controlled.
