Description
Verfahren zur Herstellung eines isolierenden Überzuges auf heissen und kalten Flüssig keitsleitungen aller Art sowie nach diesem Verfahren hergestellter Überzug. Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung eines iso lierenden Überzuges auf heissen und kalten Flüssigkeitsleitungen aller Art sowie auf einen nach diesem Verfahren hergestellten Überzug.
Nach der Erfindung wird Natronwasser- glas und Schlackenwolle zu einer zähflüssi gen, streichfertigen Masse verarbeitet, welche in mehreren Anstrichen auf die zu isolie rende Leitung aufgetragen wird.
Nach einer bevorzugten Ausführungsart des Verfahrens werden 750 Gewichtsteilen Natronwasserglas etwa 250 Gewichtsteile Schlackenwolle beigemischt und das Ganze durch Umrühren zu einer zähflüssigen, streichfertigen Masse verarbeitet.
Vor dem Aufbringen des Isolationsmittels auf die zu isolierende Leitung wird dieselbe zunächst von Fett und Rost gründlich ge reinigt. Hierauf wird die Masse mittels eines Pinsels auf die Leitung aufgestrichen und der Anstrich während fünf bis sechs Stun- den trocknen gelassen. Hiernach erfolgt ein zweiter Anstrich, den man wieder trocknen lässt.
Hierauf wird einem Teil der aus Na tronwasserglas und Schlackenwolle bestehen den zähen Flüssigkeit so viel von einem aus Gips, Champagnerkreide und Ockerfarbe be stehenden Pulver beigemischt, bis die ent stehende Masse bis zu einer ihre Streich fähigkeit nicht behindernden Konsistenz ein dickt.
Das der Natronwasserglas-Schlacken- wollenmisehung zugesetzte Pulver enthält zweckmässig etwa 30 Gewichtsteile Gips, 20 Gewichtsteile Champagnerkreide und 5 Gewichtsteile Ockerfarbe. Statt Champagner kreide kann dem Pulver auch Talkum beige mischt werden.
Die so entstandene Masse wird nun eben falls auf die Leitung aufgestrichen und trocknen gelassen. Die Flüssigkeitsleitung ist nun mit einem vorzüglichen Wärme- und Kälteisolationsmantel von etwa 2 mm Schicht dicke versehen, welcher sich sowohl für heisse wie auch für kalte Flüssigkeitsleitungen sehr gut bewährt, vorausgesetzt., dass die Leitun gen nicht starken Fibrationen unterworfen sind.
Sollen stark fibrierende Leitungen isoliert werden, so wird auf die entfettete und iso lierte Leitung zunächst ein Anstrich aus Natronwasserglas-Schlaehen-,volle aufgetra gen und dieser während etwa drei Stunden trocknen gelassen.
Hierauf wird die nun schon angetrocknete Schicht mit einer Bandage umwickelt, und zwar in steilen Windungen, welche sich an den Längsrändern nur wenig überdecken. Hiernach wird einem Teil der aus Natron- wasserblas und Schlackenwolle bestehenden Flüssigkeit ein aus Gips, Champagnerkreide (oder Talkum)
und Ockerfarbe bestehendes Pulver beigemischt und die so entstandene Masse mittels eines Pinsels auf die Bandage aufgestrichen und trocknen gelassen. Nöti genfalls kann der so hergestellte Isolations mantel mit einem weiteren aus Na.tronwasser- glas und Schlackenwolle bestehenden An strich versehen werden.
Ein wie vorstehend beschrieben herge stellter Isolationsmantel ist durchaus feuer sicher und hat den Vorteil, dass er weder fault noch rostet; ausserdem kann kein Unge ziefer darin nisten. Es ist auch möglich, für die Herstellung des Isolationsmantels alte Bandagen zu verwenden.
Gegenüber den ban- dagierten Leitungen bekannter Systeme er möglicht das erfindungsgemässe Verfahren eine Einsparung an Bandagematerial bis zu <B>80% .</B> Während das Natronwasserglas und die Schlackenwolle schon vor der Verwen- dung gemischt werden können, ist es zweck mässig, die Pulvermischung dem Natron- wasserglas-Schlackenwolle-Gemisch erst un mittelbar vor der Verarbeitung bezw. vor dem Anstrich zuzusetzen.
Process for the production of an insulating coating on hot and cold liquid lines of all types and coating produced by this process. The present invention relates to a method for producing an insulating coating on hot and cold liquid lines of all kinds and to a coating produced by this method.
According to the invention, soda water glass and slag wool are processed into a viscous, ready-to-paint mass, which is applied in several coats to the line to be insulated.
According to a preferred embodiment of the method, 750 parts by weight of soda waterglass are admixed with about 250 parts by weight of slag wool and the whole is processed by stirring to form a viscous, ready-to-spread mass.
Before applying the insulation to the line to be insulated, the same is first thoroughly cleaned of grease and rust. The compound is then brushed onto the pipe with a brush and the paint is left to dry for five to six hours. This is followed by a second coat, which is allowed to dry again.
A portion of the viscous liquid consisting of soda waterglass and slag wool is then mixed with a powder consisting of plaster of paris, champagne chalk and ocher paint until the resulting mass thickens to a consistency that does not impede its spreadability.
The powder added to the soda waterglass slag mix suitably contains about 30 parts by weight of gypsum, 20 parts by weight of champagne chalk and 5 parts by weight of ocher paint. Instead of champagne chalk, the powder can also be mixed with beige talc.
The resulting mass is now just if brushed on the line and allowed to dry. The liquid line is now provided with an excellent heat and cold insulation jacket about 2 mm thick, which has proven itself very well for both hot and cold liquid lines, provided that the lines are not subject to strong vibrations.
If lines with strong fibrillation are to be insulated, then a coat of soda waterglass tubing is first applied to the degreased and insulated line and this is allowed to dry for about three hours.
The layer, which has now dried on, is then wrapped with a bandage in steep turns that only slightly overlap at the longitudinal edges. After that, part of the liquid consisting of soda water bubble and slag wool is mixed with plaster of paris, champagne chalk (or talc)
and ocher color are mixed in and the resulting mass is brushed onto the bandage with a brush and left to dry. If necessary, the insulation jacket produced in this way can be provided with a further coating consisting of sodium water glass and slag wool.
An insulation jacket made as described above is completely fire-safe and has the advantage that it neither rot nor rust; in addition, no vermin can nest in it. It is also possible to use old bandages for the production of the insulation jacket.
Compared to the taped lines of known systems, the method according to the invention enables a saving of tape material of up to <B> 80%. </B> While the soda waterglass and the slag wool can be mixed before use, it is useful to the powder mixture the soda waterglass slag wool mixture only immediately before processing respectively. add before painting.
