Description

Säurebeständiger Druck- und Saugschlauch Es sind verschiedene gummiähnliche elastische Werkstoffe bekanntgeworden, die gegen anorganische Säuren weitgehend beständig sind, wie z. B. Polyisobutylene, Polyvinylchloride mit Weichmachern und Polyäthylene.Acid-resistant pressure and suction hose There are various rubber-like ones elastic materials have become known that are largely resistant to inorganic acids are resistant, such as B. Polyisobutylenes, polyvinyl chlorides with plasticizers and Polyethylene.

Die Herstellung von einfachen gespritzten Schläuchen aus diesen Werkstoffen ist verhältnismäßig einfach. Schwierigkeiten bereitet dagegen die Herstellung von Druck- und Saugschläuchen, weil man werkstoffmäßig nicht auf die in der Gummitechnik übliche Konfektionierungsart zurückgreifen kann. Die bisher als Stütze üblichen Metallspiralen können innen frei liegend nicht verwendet werden wegen der Empfindlichkeit gegen anorganische Säuren. Versuche haben gezeigt, daß auch eine in der Schlauchwandung eingebettete Metallspirale im Laufe der Zeit von durchdiffundierenden Säuren angegriffen wird, wobei sich im Schlauch durch Wasserstoffentwicklung Blasen bilden.The production of simple injection-molded hoses from these materials is relatively easy. On the other hand, the production of Pressure and suction hoses, because the material used in rubber technology can fall back on the usual type of packaging. The ones previously used as a support Metal spirals cannot be used if they are exposed on the inside because of their sensitivity against inorganic acids. Tests have shown that there is also one in the hose wall embedded metal spiral attacked by diffusing acids over time bubbles forming in the tube due to the evolution of hydrogen.

Es wurde nun gefunden, daß man einen in jeder Beziehung einwandfreien Druck- und Saugschlauch aus den oben bezeichneten Werkstoffen erhält, wenn als Stütze eine Wendel aus weichmacherfreiem Polyvinylchlorid verwendet wird, die entweder frei auf der Innenwandung des Schlauches liegt oder als aus Kunststoff teestehende Stütze mittels geeigneter Klebstoffe bzw. Lösungsmittel mit dem Schlauchmaterial verbunden bzw. in die Schlauchwandung eingebettet ist. Die Bedeutung eines so aufgebauten Druck- und Saugschlauches wird besonders durch das angeführte Beispiel i klar. Danach hat der Kunststoffschlauch lediglich auf der Innenseite, frei liegend, eine Polyvinylchloriddrahtstütze, die dann mit dem Schlauch fest verbunden ist. Ein auf diese Weise aufgebauter Schlauch kann unmittelbar als Druckschlauch verwendet werden. Die in Frage kommenden Kunststoffe können mit Metall nicht so fest verbunden werden, daß sich die Verbindungsstelle bei Druckbeanspruchung nicht löst.It has now been found that one is impeccable in every respect Pressure and suction hose made of the materials specified above is given if used as a support a helix made of plasticizer-free polyvinyl chloride is used, either lies freely on the inner wall of the hose or as a tea-standing made of plastic Support by means of suitable adhesives or solvents with the Hose material is connected or embedded in the hose wall. The meaning a pressure and suction hose constructed in this way is particularly indicated by the Example i clear. After that, the plastic hose only has on the inside, exposed, a polyvinyl chloride wire support, which is then firmly connected to the hose is. A hose constructed in this way can be used directly as a pressure hose be used. The plastics in question cannot do this with metal be firmly connected so that the connection point is not under pressure solves.

Auch in den Fällen, wo die Spirale in der Schlauchwandung eingebettet ist, ist eine innige Verbindung des harten Polyvinylchloriddrahtes mit dem elastischen Werkstoff gemäß der Erfindung möglich. Um die Druckfestigkeit eines Schlauches nach der Erfindung zu erhöhen, kann derselbe zusätzlich mit einem Polyvinylchloridgeflecht versehen werden, das ebenfalls mittels geeigneter Lösungsmittel oder Klebstoffe mit der äußeren Schlauchwandung verbunden werden kann. Beispiel i Auf einem Metalldorn entsprechend der lichten Weite des gewünschten Schlauches wird ein Polyvinylchloriddraht wendelförmig gewickelt und an den Enden befestigt. Ein entsprechend großer Schlauch aus Polyisobutylen wird innen mit einer Benzöllösung eines Gemisches aus Polyisobutylen und Polyvinylchlorid bestrichen und auf den Dorn aufgezogen und bandagiert. Durch nachträgliches Erhitzen preßt sich die Wendel in die Schlauchwandung, mit der sie gleichzeitig verklebt wird. Beispiel 2 Auf einen Metalldorn wird ein Schlauch aus Pölyvinylchlorid aufgezogen und mit einem Polyvinylchloriddraht wendelförmig umwickelt. Die Wendel und der Schlauch werden mit einer Paste aus Polyvinylchlorid mit Weichmacher bestrichen und mit einem zweiten Schlauch aus Polyvinylchlorid überzogen und fest bandagiert. Durch nachträgliches Erhitzen auf eine für die Gelatinierung der Paste notwendige Temperatur erhält man eine vollkommene feste Verbindung zwischen den drei Bestandteilen des Schlauches.Even in cases where the spiral is embedded in the hose wall is, is an intimate connection of the hard polyvinyl chloride wire with the elastic Material according to the invention possible. In order to determine the compressive strength of a hose of the invention, the same can be added with a polyvinyl chloride braid be provided, which also by means of suitable solvents or adhesives can be connected to the outer hose wall. Example i On a metal mandrel a polyvinyl chloride wire is used according to the clear width of the desired hose helically wound and attached at the ends. A correspondingly large hose from polyisobutylene is inside with a benzene solution of a mixture of polyisobutylene and polyvinyl chloride coated and drawn onto the mandrel and bandaged. By subsequent heating presses the coil into the hose wall with which it is glued at the same time. Example 2 A hose is made from a metal mandrel Polyvinyl chloride drawn up and wrapped in a spiral shape with a polyvinyl chloride wire. The coil and the hose are made with a paste of polyvinyl chloride with plasticizer smeared and covered with a second tube made of polyvinyl chloride and solid bandaged. By subsequent heating on one for the gelatinization of the paste necessary temperature you get a perfect solid connection between the three components of the hose.
