Description

Kunstharzplatten, 2. B. Platten aus Phenolformaldehyd- oder Harnstoffkondensationsprodukten u. dgl., wurden bisher so poliert, daß man zunächst die vom Block geschnittenen 5 oder gesägten Platten oder auch die durch Pressen hergestellten Platten, mit Schmirgel plan schliff und hierauf die kleinen Unebenheiten, die der Schmirgel hinterlassen hatte, mit in Wasser aufgeschlemmtem Bimssand entfernte. Dann wurde auf Schwabbelscheiben und Hochglanzpolierscheiben die erforderliche Hochglanzpolitur erzeugt. Dieses letztere Verfahren ist ziemlich langwierig und kostspielig, und vor allem ist der erreichte Poliereffekt für viele Zwecke ungenügend.Synthetic resin panels, 2. B. panels made of phenol formaldehyde or urea condensation products and the like, have hitherto been polished by first cutting the blocks cut from the block 5 or sawn panels or the panels made by pressing, with emery sanded flat and then the small bumps left by the emery, removed with pumice sand suspended in water. Then was on buffing discs and high-gloss polishing discs produces the required high-gloss polish. This latter method is rather tedious and expensive, and most importantly is the polishing effect achieved insufficient for many purposes.

Es ist ferner bekannt, Platten aus Celluloid zwischen hochglanzpolierten Blechen unter Erhitzung zu pressen, wobei die Platten eine dauerhafte Hochglanzpolitur erhalten.It is also known to place sheets of celluloid between highly polished metal sheets Pressing by heating, giving the plates a permanent high-gloss polish.

Die Erfindung besteht darin, Kunstharzplatten (nach dem bekannten Planschleifen und der bekannten Behandlung mit einer Aufschlemmung von Bimsstein in Wasser oder anderen Flüssigkeiten oder auch einer Behandlung mit anderen feuchten Schleifmittelzusammensetzungen) in Polierpressen von der Art der Celluloidpolierpressen zwischen hochglanzpolierten Metallblechen in der Wärme einem hohen Druck zu unterwerfen, wobei sich die Politur der Metallbleche auf die Kunstharzplatten überträgt. Die voraufgeheride Behandlung mit einer Aufschlemmung von Bimsstein und Flüssigkeiten oder mit ähnlichen feuchten Schleifmitteln ist zur Erzielung einer ausreichenden Politur Vorbedingung, weil ohne diese bei der nachfolgenden Pressung so hohe Drucke und Temperaturen erforderlich würden, daß eine Deformierung, unter Umständen sogar ein Bruch der Platten unvermeidlich ist.The invention consists in making synthetic resin plates (after the known surface grinding and the known treatment with a suspension of pumice stone in water or other liquids or treatment with other wet abrasive compositions) in polishing presses of the type of celluloid polishing presses between highly polished ones To subject metal sheets in the heat to a high pressure, with the polishing of the metal sheets on the Resin plates transfers. The previous treatment with a slurry of Pumice stone and liquids or similar wet abrasives is used to achieve a Sufficient polish is a prerequisite, because without this during the subsequent pressing so high pressures and temperatures would be required that deformation, under Under certain circumstances, even a break in the plates is inevitable.

Die nach dem neuen Verfahren bei Kunstharzplatten erreichte Hochglanzpolitur übertrifft die in der Einleitung erwähnte, mit Schwabbeln erzielte Politur bei weitem.The high-gloss polish achieved with synthetic resin panels using the new process is exceeded the polish achieved with buffing mentioned in the introduction by far.
