Description

Verfahren zur Herstellung von Filterpressenplatten aus Phenol-Aldehyd-Kondensationsprodukten und Zusatzstoffen. Bei der Herstellung von Filterpressenplatten ist auf die Herstellung von Rillen bzw. Tianälen besondere Sorgfalt anzuwenden. Bei Bußeisernen Platten lassen sich solche Rillen leicht durch den Gießvorgang .erzeugen; bei hölzernen Platten wer den die Rillen mittel Stahlfräsern in das Holz hineingearbeitet; bei Hart.gunlinipiatten kann die gute Preßfähigkeit der benutzten lIartgulllillikollipositionen für diesen Zweck ausgenutzt werden.Process for the production of filter press plates from phenol-aldehyde condensation products and additives. In the manufacture of filter press plates is on the production special care must be taken in grooves and grooves. With penal iron plates can such grooves easily .generate by the casting process; with wooden ones Plates who cut the grooves into the wood using steel cutters; at Hart.gunlinipiatten can use the good compressibility of the used lIartgulllillikollipositionen be exploited for this purpose.

Keine dieser Methoden kann auf Platten Verwendung finden, welche aus Plietiol AIdehyd-Iiondensationsprodtikten und Zusatzstoffen, z. E. Asbest, Quarzpulver usw. bestehen. Solche Kompositionen lassen sich bekanntlich nicht gießen; auch ist ein rationelles Preßverfahren für derartige Werkstücke nicht bekannt. Die Bearbeitung mittels Staht-@verl:ze@ugen, z. B. durch Stahlfräser, scheitert an der überraschend großen 311ntitzung der Werkzeuge. So genügen schon einige NIilltttell Arbeitsdauer eines noch so ausgezeichneten Fräsers aus bestem Spezialstahl -in der obenerwähnten honipositionsinasse, uni diesen vollkommen stumpf tmil unbrauchbar zu machen. -Dies ist ein erheblicher technischer- Nachteil.
