Abstract
Keramisch glas wordt ontspiegled door een proces van polijsten, wassen, metaalhoudende coatings en harding voor kleurvast gebruik in gashaarden om het effect van een open haard beter te benaderen.Ceramic glass is relaxed by a process of polishing, washing, metallic coatings and curing for colorfast use in gas fires to better approximate the effect of a fireplace.
Description
De uitvinding heeft betrekking op ontspiegeld glas voor gebruik in gashaarden.The invention relates to anti-reflective glass for use in gas fires.
Tenzij anders gedefinieerd hebben alle termen die gebruikt worden in de beschrijving van de uitvinding, ook technisch en wetenschappelijke termen, de betekenis zoals ze algemeen begrepen worden door de vakman in het technisch veld van de uitvinding. Voor een betere beoordeling van de beschrijving van de uitvinding, worden de volgende termen expliciet uitgelegd.Unless defined otherwise, all terms used in the description of the invention, including technical and scientific terms, have the meaning as generally understood by those skilled in the art of the invention. For a better assessment of the description of the invention, the following terms are explicitly explained.

Bijvoorbeeld, “een segment” betekent een of meer dan een segment."One", the "and" the "in this document refer to both the singular and the plural unless the context clearly assumes otherwise. For example, "a segment" means one or more than one segment.
Wanneer “ongeveer” of “rond” in dit document gebruikt wordt bij een meetbare grootheid, een parameter, een tijdsduur of moment, en dergelijke, dan worden variaties bedoeld van +/-20% of minder, bij voorkeur +/-10% of minder, meer bij voorkeur +/-5% of minder, nog meer bij voorkeur +/1% of minder, en zelfs nog meer bij voorkeur +/-0.1% of minder dan en van de geciteerde waarde, voorzoverre zulke variaties van toepassing zijn in de beschreven uitvinding. Hier moet echter wel onder verstaan worden dat de waarde van de grootheid waarbij de term“ongeveer” of “rond” gebruikt wordt, zelf specifiek wordt bekendgemaakt.When "about" or "round" is used in this document for a measurable quantity, a parameter, a duration or moment, and the like, variations are meant of +/- 20% or less, preferably +/- 10% or less, more preferably +/- 5% or less, even more preferably + / 1% or less, and even more preferably +/- 0.1% or less than and of the quoted value, insofar as such variations apply in the described invention. However, this must be understood to mean that the value of the quantity in which the term "approximately" or "round" is used is itself specifically disclosed.
De termen “omvatten”, “omvattende”, “bestaan uit”, “bestaande uit”, “voorzien van”, “bevatten”, “bevattende”, “behelzen”, “behelzende”, “inhouden”,“inhoudende” zijn synoniemen en zijn inclusieve of open termen die de aanwezigheid van wat volgt aanduiden, en die de aanwezigheid niet uitsluiten of beletten van andere componenten, kenmerken, elementen, leden, stappen, gekend uit of beschreven in de stand der techniek.The terms "include," "include," "consist of," "include," "contain," "contain," "include," "include," and are inclusive or open terms indicating the presence of what follows, and which do not exclude or prevent the presence of other components, features, elements, members, steps, known from or described in the prior art.
Het citeren van numerieke intervallen door de eindpunten omvat alle gehele getallen, breuken en/of reële getallen tussen de eindpunten, deze eindpunten inbegrepen.The citation of numerical intervals by the end points includes all integers, fractions and / or real numbers between the end points, including these end points.
Gashaarden worden steeds belangrijker, omdat traditionele houthaarden door milieunormen worden geweerd. De gashaarden worden meestal groot gemaakt om een mooi vlammenbeeld te krijgen.Gas fires are becoming increasingly important because traditional wood fires are kept out by environmental standards. The gas fires are usually made large to get a beautiful flame image.
Ze dienen niet enkel meer als verwarming maar ook als sfeerscheppers. Om die reden wil men ook de vlammen en evëntueël nagemaakte houtblokken kunnen zien alsof het een echte open houthaard was zonder glas.They no longer serve only as heating but also as atmosphere creators. For that reason, they also want to be able to see the flames and possibly fake logs as if it were a real open wood-burning stove without glass.
Met het meestal gebruikte keramisch glas, lukt deze indruk niet omdat het keramisch glas reflecteert.With the mostly used ceramic glass, this impression does not work because the ceramic glass reflects.
Het keramisch glas is nochtans heel nuttig in deze toepassing omdat de uitzettingsgraad omzeggens nul is en het glas hittebestendig is.However, the ceramic glass is very useful in this application because the degree of expansion is almost zero and the glass is heat-resistant.
Keramisch glas tussen 3 en 6mm dikte wordt gebruikt.Ceramic glass between 3 and 6 mm thickness is used.
B E2018/0031B E2018 / 0031
Voor deze toepassing moet keramisch glas gepolijst worden aan beide zijden zodat de anti-reflective coating perfect uniform aangebracht kan worden op het glasoppervlak.For this application, ceramic glass must be polished on both sides so that the anti-reflective coating can be perfectly uniformly applied to the glass surface.
Voor de coating ondergaat het keramisch glas een grondige wasbeurt met o.a. ceriumoxide.Before the coating, the ceramic glass undergoes a thorough wash with, among other things, cerium oxide.
Het gewone keramisch hittebestendig glas heeft een reflectie van 8%. Door de hier beschreven ontspiegelingscoating wordt de reflectie verminderd tot 0,7% in loodrechte positie.The ordinary ceramic heat-resistant glass has a reflection of 8%. The anti-reflective coating described here reduces the reflection to 0.7% in the perpendicular position.
Reflectie onder 1% neemt het menselijk oog niet waar.Reflection below 1% is not perceived by the human eye.
De ontspiegeling gebeurt dooreen coating van 5 lagen aan weerszijden van het keramisch glas, die voldoet aan de duuuzaamheidstesten volgens ISO9211 voorabrasie en coating adhesie, EN 12792 voor klimaatschommelingen, EN 1096-2 voor UV, condensatie en neutrale zoutsproei. De 10 coatings van metaaloxides worden aangebracht door een sputteringsproces. Deze coatings zijn metaaloxidelagen die de reflectie verminderen en die bovendien ook gedeeltelijk de infrarode straling tegenhouden. Daardoor geeft de gashaard tot 10% minder warmte wat nuttig is aangezien gashaarden meestal geoverdimensioneerd zijn en dikwijlss te sterk in de nabije omtrek verwarmen. Door de weerkaatsing van de infrarode straling, zorgen de metaaloxidecoatings voor iets hogere 15 temperaturen in de verbrandingskamer van de haard met een betere verbranding en en minder emissie van partikels als gevolg.The anti-reflective effect is achieved by coating 5 layers on both sides of the ceramic glass, which meets the durability tests according to ISO9211 pre-abrasion and coating adhesion, EN 12792 for climatic fluctuations, EN 1096-2 for UV, condensation and neutral salt spray. The 10 coatings of metal oxides are applied by a sputtering process. These coatings are metal oxide layers that reduce reflection and that also partially block infrared radiation. As a result, the gas fire provides up to 10% less heat, which is useful since gas fireplaces are usually over-dimensioned and often heat too strongly in the near perimeter. Due to the reflection of the infrared radiation, the metal oxide coatings cause slightly higher temperatures in the combustion chamber of the fireplace, resulting in better combustion and less particle emission.
Na het aanbrengen van de coatings, wordt het keramisch glas nog gehard in een oven met temperatuur tussen 650’C en 750°C gedurende 2 à 6 minuten. Dit zorgt voor grotere kieurvastheid, en verhindert onregelmatige verkleuring van het gecoate keramisch glas.After applying the coatings, the ceramic glass is still hardened in an oven with a temperature between 650 ° C and 750 ° C for 2 to 6 minutes. This ensures greater resistance to cracks, and prevents irregular discolouration of the coated ceramic glass.
De gecoate en geharde glasplaten worden van mekaar gescheiden gehouden met kurk.The coated and tempered glass plates are kept separate with cork.
