Description
Verfahren zum Erzeugen sehr dünner Glasfolien Es ist bekannt, dünne Glasfolien durch Blasen herzustellen. Die Folien fallen aber ziemlich ungleichmäßig aus, auch sind sie oft mehrfach 'gekrümmt, so daß sie sich nicht flach legen lassen. Das letztere ist darauf zurückzuführen, daß sich die geblasenen Ballone oft schlan.Clenartig krümmen.Method for producing very thin glass films It is known that thin Manufacture glass foils by blowing. However, the foils fall quite unevenly off, and they are often curved several times so that they cannot be laid flat. The latter is due to the fact that the blown balloons are often slender bend.
Die Erfindung hat die Aufgabe, die Herstellung solcher Fol:.en zu erleichtern und insbesondere die Herstellung gleichmäßig dün-Z, t' zi ner Folien zu ermöglichen.The invention has the task of producing such fol: .en to facilitate and in particular the production of evenly thin-Z, t'zi ner foils to enable.
Die Erfindung kann auch dazu angewendet werden, besonders dünne Folien, beispielsweise Folien mit einer Dicke von weniger als 5 li., zu erhalten. Diese Folien haben eine höhere spezifische Festigkeit und sind viel biegsamer als dickere Folien. Auch kann die Erfindung an gewendet werden, um größere Ballone mit weniger stark gekrümmten Folienflächen zu erhalten.The invention can also be used to obtain particularly thin films, for example films with a thickness of less than 5 li. These foils have a higher specific strength and are much more flexible than thicker foils. The invention can also be used to obtain larger balloons with less strongly curved film surfaces.
Erfindungsgemäß wird der erhitzte Glaskörper während des Ausblasens der Einwirkung von Ultraschall ausgesetzt.According to the invention, the heated glass body becomes during the blowing out exposed to the action of ultrasound.
Die Erfindung soll an Hand der Zeichnung näher erläutert werden. Das an einem Ende zugeschmolzene und erhitzte Glasrohr i, das an eine Druck-quelle- angeschlossen ist, wird zu einem Ballon 2 ausgeblasen. Der Gasinhalt des Ballons w.,rd beim Ausblasen beispielsweise durch eine nach dem Prinzip der Ma-"netostrik a -tion arbeitende Ultraschallquelle 3 in hochfrequente Schallschwingungen versetzt, deren Amplitude und Fre4uenz der jeweiligen Glassorte angepaßt wird. Außerdem kann auch das Glasrohr i während des Ausblasens durch eine Ultraschallquelle in Schwingungen versetzt werden, indem man es beispielsweise mit einer geeigneten übertragungsvorrichtung4 für den Ultraschall verbindet. Unter Umständen empfiehlt es sich, gleichzeitig mehrere Ultraschallquellen auf den auszublasenden Glaskörper oder auf den Gasraum in dem Glaskörper während des Ausblasens in verschiedenen Richtungen mit verschiedener Phase oder Frequenz einwirken zu lassen.The invention will be explained in more detail with reference to the drawing. The glass tube i, melted shut at one end and heated, which is connected to a pressure source, is blown out to form a balloon 2. The gas content of the balloon w., Rd when blown out, for example, by an ultrasonic source 3 operating on the principle of magnetostrics, is set into high-frequency sound oscillations, the amplitude and frequency of which is adapted to the respective type of glass Blowing out can be made to vibrate by an ultrasound source, for example by connecting it to a suitable transmission device4 for the ultrasound. It may be advisable to simultaneously apply several ultrasound sources to the glass body to be blown out or to the gas space in the glass body while blowing in different directions in different directions Let phase or frequency act.
Die Erfindung bietet den Vorteil, daß die Ballone gleichmäßiger, dünner und größer ausgeblasen werden können, namentlich wenn man in einem beheizten Raum oder mit erhitztem Gas bläst. Auch kann rascher als sonst geblasen werden, weil Ultraschall die Cberführung der Glasschmelze in die Folienform erleichtert und beschleunigt.The invention offers the advantage that the balloons are more uniform, thinner and can be blown out larger, especially if you are in a heated room or blows with heated gas. It is also possible to blow faster than usual because Ultrasound facilitates and accelerates the transfer of the molten glass into the film form.
