Description

Verfahren zum Verspiegeln von Glas- oder anderen Oberflächen aus nichtleitenden Stoffen. Es ist bekannt, daß man zum Verspiegeln von Glas und anderen nichtleitenden Stoffen die zu verspiegelnden Flächen aufs sorgfältigste reinigen muß. Hierzu werden die verschiedensten Mittel verwendet, insbesondere Säure, Ätzlauge, Alkohol. Es ist auch vorgeschlagen worden, um eine besonders nachdrückliche Reinigung dieser Flächen zu erzielen, hierfür Flußsäure zu verwenden.Process for mirroring glass or other non-conductive surfaces Fabrics. It is known that one can be used to mirror glass and other non-conductive Fabrics must carefully clean the surfaces to be mirrored. To do this will be the most diverse means are used, in particular acid, caustic solution, alcohol. It has also been suggested to do a particularly vigorous purification of this To achieve surfaces to use hydrofluoric acid for this.

Es hat sich nun überraschenderweise herausgestellt, daß man in viel einfacherer und zweckmäßigerer Weise die zu verspiegelnden Flächen für eine glatte Verspiegelung geeignet machen kann, wenn man sie erfindungsgemäß vorher mit einer dünnen Formaldehydlösung behandelt. Wendet man diese Vorbehandlung an, so kann man in den allermeisten Fällen jede weitere Vorreinigung des Glases entbehren. Bei der Behandlung mit Formaldehyd treten die ersten Keime, z. B. Silberkeime, auf dem Glase in außerordentlicher Regelmäßigkeit auf, so daß sich auf diesen Silberkeimen die weiteren Silberteilchen in außerordentlicher Gleichmäßigkeit abscheiden. Das neue Verfahren ,eignet sich sowohl zur Herstellung von Silberspiegeln und Spiegeln anderer Edelmetalle wie auch zur Herstellung von Kupferspiegeln usw. Das Verfahren bedeutet nicht bloß einen technischen, sondern auch einen beachtenswerten wirtschaftlichen Erfolg, da man sowohl an Chemikalien wie auch an Arbeitskräften durch die geringere Zahl von Einzeloperationen Ersparnisse erzielt. Für die Zwecke der Erfindung eignet sich schon eine Formaldehydlösung, die z. B. z ccm Formalin in r o 1 Wasser enthält. Man braucht zum Spülen kein destilliertes Wasser zu verwenden.It has now been found, surprisingly, that one can work in a lot Easier and more appropriate way the surfaces to be mirrored for a smooth Can make mirroring suitable if you according to the invention beforehand with a treated with a thin formaldehyde solution. If you apply this pretreatment, you can In the vast majority of cases, there is no need for any further pre-cleaning of the glass. In the Treatment with formaldehyde shows the first germs, e.g. B. silver germs on the glass with extraordinary regularity, so that the separate further silver particles with extraordinary uniformity. The new Process, is suitable both for the production of silver mirrors and mirrors of others Precious metals as well as for the production of copper mirrors etc. The process means not just a technical one, but also a notable economic one Success because you have fewer chemicals and fewer workers Number of individual operations achieved savings. Suitable for the purposes of the invention a formaldehyde solution that z. B. contains z cc of formalin in r o 1 of water. There is no need to use distilled water for rinsing.

Beim Verspiegeln von Glas oder anderen Oberflächen aus nichtleitenden Stoffen hat Formaldehyd bisher nur als Bestandteil der Verspiegelungsflüssigkeit Anwendung gefunden.When mirroring glass or other non-conductive surfaces Formaldehyde has so far only contained substances as a component of the mirroring liquid Application found.
