Description
Verfahren zum Herstellen von Folien Die Erfindung betrifft ein Verfahren zum Herstellen von Folien aus plastischen Cellulosemassen, insbesondere solchen, welche Celluloseäther oder -ester, z. B. Acetylcellulose oder Nitrocellulose, als Grundlage haben und von verhältnismäßig geringer Dicke, nämlich im fertigen Zustande o,o8 bis o,9 mm stark, sind. Es ist bekannt, Folien durch Ausstoßen einer plastischen Cellulosemasse aus einem entsprechend gestälteten Mundstück unter nachfolgendem Strecken der Folie herzustellen.Method for producing foils The invention relates to a method for the production of foils from plastic cellulose masses, especially those which cellulose ethers or esters, e.g. B. acetyl cellulose or nitrocellulose, as Have a basis and of relatively small thickness, namely in the finished state 0.08 to 0.9 mm thick. It is known that foils by ejecting a plastic Cellulose mass from a correspondingly shaped mouthpiece below Stretch the film to manufacture.
Demgegenüber besteht die Erfindung darin, daß die plastische Masse vor dem Ausstoßren auf eine erhöhte, mindestens 4.5° betragende Temperaturerhitzt und die Folie sofort nach dem Verlassen des Mundstückes in einem gekühlten, zweckmäßig 15° nicht übersteigenden Härtebad zum Erstarren gebracht wird. Hierdurch werden Folien vollkommen gleichmäßiger Dicke und von vorzüglicher Beschaffenheit erhalten, die insbesondere als Zvwischenschichten für Verbundglas Verwendung finden können.In contrast, the invention consists in that the plastic mass heated to an elevated temperature of at least 4.5 ° before ejection and the foil immediately after leaving the mouthpiece in a cooled, expedient 15 ° hardness bath is made to solidify. This will be Sheets of perfectly uniform thickness and of excellent quality are preserved, which can be used in particular as intermediate layers for laminated glass.
Die Verarbeitung der plastischen Masse kann z. B. in der in der Zeichnung schematisch dargestellten Einrichtung erfolgen. Aus einem Behälter i wird die plastische Masse' durch einen Kolben a unter Druck durch ein. schlitzartiges Mundstück 3 ausgestoßen. Daran schließt sich eine Härteeinrichtung, z. B. ein Bad ¢, an, in dem Tragwalzen 5 für die plastische Folie S vorgesehen sind. Die Folie gelangt sodann über eine frei aufgehängte Belastungswalze 6, die sie anspannt zwischen angetriebenen Walzen 7, die zur Fortbewegung der Folie dienen, hindurch in ein zweites Bad oder eine Kammer 8 mit Tragwalzen 9 und endlich zu angetriebenen Spannwalzen ro. Hierbei können die einzelnen Teile mit Einrichtungen versehen werden, um die Temperatur zu regeln, z. B. Doppelmänteln, Schlangen usw., doch sind diese in der Zeichnung der Einfachheit wegen weggelassen.The processing of the plastic mass can, for. B. in the drawing facility shown schematically take place. A container i becomes the plastic one Mass' through a piston a under pressure through a. slot-like mouthpiece 3 ejected. This is followed by a hardening device, e.g. B. a bath ¢, in the support rollers 5 are provided for the plastic film S. The film then passes over a freely suspended loading roller 6, which it tensions between driven rollers 7, which are used to move the film, through into a second bath or a Chamber 8 with support rollers 9 and finally to driven tension rollers ro. Here you can the individual parts are provided with devices to regulate the temperature, z. B. double coats, snakes, etc., yet these are in the drawing for simplicity because of omitted.
Die auf mindestens ¢5° erwärmte plastische Masse p wird aus dem Behälter 1 durch das Mundstück 3 als eine halb formbeständige Bahn S von teigartiger Beschaffenheit in das gekühlte Härtebad q. gepreßt, in dem eine weitgehende Entfernung der Lösungsmittel und infolgedessen eine gewisse Härtung der Folie stattfindet, so daß sich dadurch ihre Formbeständigkeit erhöht. Aus dem Bad tritt die Folie in die Kammer 8, die zweckmäßig ein zweites Härtebad enthalten kann, und danach zwischen den Walzen ro aus, um dann in einzelne Stücke von gewünschter Größe geschnitten und getrocknet zu werden.The plastic mass p, heated to at least ¢ 5 °, is removed from the container 1 through the mouthpiece 3 as a semi-dimensionally stable web S of dough-like nature in the cooled hardening bath q. pressed, in which a substantial removal of the solvent and consequently a certain hardening of the film takes place, so that thereby their dimensional stability increases. From the bath, the film enters the chamber 8, which can expediently contain a second hardening bath, and then ro between the rollers off, then cut into individual pieces of desired size and dried to become.
Das Härtebad besteht beispielsweise aus Methylalkohol und Wasser; Glycerin und Wasser; Natriumchlorid und Wasser; Rohrzucker und Wasser; Rohrzucker, Wasser und Methylalkohol.The hardening bath consists, for example, of methyl alcohol and water; Glycerin and water; Sodium chloride and water; Cane sugar and water; Cane sugar, Water and methyl alcohol.
Die Temperatur des Härtebades kann zwischen einer Temperatur dicht oberhalb seines Gefrierpunktes und q.0° C gehalten werden. Zweckmäßig aber beträgt sie nicht mehr als 150.The temperature of the hardening bath can be between a temperature dense above its freezing point and q.0 ° C. Appropriately, however they do not exceed 150.
