Description
Verfahren zum Behandeln von Feuerwehrschläuchen und nach diesem Verfahren behandelter Feuerwehrschlauch. Es ist bereits ein Verfahren patentiert (Schweizer Patent Nr. 2124g3), nach welchem trockene Feuerwehr-Hanfschläuclie mit einer gummiartigen Flüssigkeit von innen Heraus imprägniert niid damit wasserdielit gemacht werden.
Bei dein Verfahren gemäss vorliegender Erfindung hingegen werden die Feuerwehr schläuche vorerst mit einer Lösung imprä gniert, welche die Feuerwehrsehläuclie was serabstossend macht und sie gegen Fäulnis schützt, worauf diese Schläuche finit einer ein Abdichtungsmittel enthaltenden Flüssigkeit gefüllt werden, welche in die Poren und in allfällige Öffnungen, z. B. Risse, im Schlauch eindringt und nach einiger Zeit wieder ent leert werden, wodurch die Feuerwehrschläu che nach dein Trocknen wasserdicht werden.
Der nach diesem Verfahren abgedichtete Feuerwehrschlaueli kennzeichnet sich durch eine Imprägnierung, die wasserabstossend wirkt und gegen Fäulnis schützt, und der im Innern eine Sehiclit aufweist, welche den Feuerwehrschlauch abdichtet.
Mit nachfolgendem Beispiel wird gezeigt, wie das Verfahren der vorliegenden Erfin dung praktisch ausgeführt werden kann.
Der zu behandelnde Feuerwehrschlauch aus Hanfgewebe wird in ein Imprägnierbad gelegt, das mit einer paraffinhaltigen Lösung gefüllt ist. Diese dringt in die Poren des Ge webes. Nach einiger Zeit wird der Schlauch aus dein Bad herausgenommen. Derselbe ist durch diese Imprägnierung wasserabstossend geworden und ist gleichzeitig gegen Fäulnis besser gesehfitzt. Der Feuerwehrschlauch wird sodann aufgehängt, am. untern Ende ver schlossen und mit einer kautschukhaltigen Flüssigkeit, z. B. vulkanisierbarem Kautschuk milch, sogen. Latex , gefüllt.
Diese Flüssig keit dringt ebenfalls in die Poren des Hanf schlauches, durch kleine Öffnungen, Risse hindurch und erstarrt an den Stellen, an wel chen sie durch dieselben mit Luft in Berüh rung kommt.
Dadurch werden die Öffnungen, Risse verschlossen. Es entstehen so an den vorher undichten Stellen verstärkte Kautschukschich ten. Daraufhin wird der Schlauch entleert. Man lässt ihn vollständig trocknen. Sodann schüttet man von oben her Talkum-Streupul- ver in den Schlauch.
Ein so behandelter Feuerwehrschlauch zeichnet sich durch grosse Haltbarkeit aus. Weil das Hanfgewebe wasserabstossend ge macht ist, kann dasselbe nicht von aussen her durchnässt werden; das Gewebe kann somit weniger in Fäulnis übergehen. Die unbehan delten Feuerwehrschläuche können, wenxi durchnässt, im Winter einfrieren und da durch Schaden nehmen. Der Feuerwehr sehlauch nach der vorliegenden Erfindung kann nicht einfrieren.
Durch die Behandlung der Innenwand der Feuerwehrschläuche mit der kautschuk- haltigen Flüssigkeit wird diese Innenwand glatt. Eine solche Wandung bietet dem durch fliessenden Wasser weniger Reibungswider stand; es geht daher im Schlauch weniger Druck verloren; die Reichweite des Wasser strahls ist grösser; die Leistung ist höher.
Nach dein vorliegenden Verfahren können nicht nur Hanfschläuche, sondern auch Schläuche aus Flachs, Baiunwolle, Ramie und Lederschläuche verbessert werden.
Process for treating fire hoses and fire hoses treated according to this process. A process has already been patented (Swiss patent no. 2124g3), according to which dry fire brigade hemp hoses are impregnated with a rubber-like liquid from the inside out and made water-resistant.
In your method according to the present invention, however, the fire brigade hoses are first impregnated with a solution that makes the fire brigade hoses repellent and protects them against rot, whereupon these hoses are filled with a liquid containing a sealant, which is filled into the pores and into any openings , e.g. B. cracks, penetrates the hose and after some time again ent emptied, whereby the fire hoses are waterproof after your drying.
The fire brigade rogue sealed according to this process is characterized by an impregnation which has a water-repellent effect and protects against rot, and which has a Sehiclit inside which seals the fire hose.
The following example shows how the method of the present invention can be practiced.
The fire hose to be treated, made of hemp fabric, is placed in an impregnation bath filled with a paraffin-based solution. This penetrates into the pores of the tissue. After a while, the hose will be removed from your bathroom. This impregnation has made it water-repellent and at the same time is better protected against rot. The fire hose is then hung up, closed at the lower end and treated with a rubber-containing liquid, e.g. B. vulcanizable rubber milk, absorbed. Latex, filled.
This liquid also penetrates into the pores of the hemp hose, through small openings, cracks and solidifies at the points where it comes into contact with air.
This closes the openings and cracks. This creates reinforced layers of rubber at the previously leaky spots. The hose is then emptied. Let it dry completely. Then pour talcum powder into the hose from above.
A fire hose treated in this way is characterized by its great durability. Because the hemp fabric is made water-repellent, it cannot be soaked from the outside; the tissue is less likely to go into putrefaction. The untreated fire hoses can, if soaked, freeze in winter and be damaged as a result. The fire hose according to the present invention cannot freeze.
Treating the inner wall of the fire hoses with the rubber-containing liquid makes this inner wall smooth. Such a wall offers the flowing water less frictional resistance; less pressure is therefore lost in the hose; the range of the water jet is greater; the performance is higher.
According to your present method, not only hemp tubes, but also tubes made of flax, cotton, ramie and leather tubes can be improved.
