DENSO-CHEMIE GMBH,, 509 Leverkusen 6, Felder straßeDENSO-CHEMIE GMBH ,, 509 Leverkusen 6, Felderstrasse Kombinat ioni;band für den KorrosionsschutzCombination tape for corrosion protection

I- Erdboden verlegte Rohrleitungen >asr sonstige Installationen kann man nach zwei Methoden gegen die Korrosion durch elektrochemischen Angriff schützen, nämlich durch Umhüllungen oder Umkleidungen (passiver Korrosionsschutz), die dem angreifenden Medium den Zutritt verwehren sowie durch das kathodische Korrosionsschutzverfahren (aktiver Korrosionsschutz), bei welchen die Elektronen für die im Kathodengebiet erfolgende Reduktion des für den Ablauf der Eorroslcs verantwortlichen Sauerstoffes durch galvanische Anod«·:» od«r durch eine Fremdstromanlage gelieitert werden* Beide Verfahren werden am zweckmäßigsten gleichseitig angewandt; sie sind dann besonders wirtschaftlich, wenn die Umhüllung der korrosionsgefährdeten erdverlegten Installationen hochwertig ist.I- Pipelines laid in the ground > As for other installations, there are two methods of protecting against corrosion caused by electrochemical attack, namely by sheaths or casings (passive corrosion protection), which prevent the attacking medium from entering, and by means of the cathodic corrosion protection process (active corrosion protection) to which the electrons for the reduction of the oxygen responsible for the process of erosion in the cathode area are supplied by galvanic anod "·:" or "r by an external current system. they are particularly economical if the casing of the underground installations at risk of corrosion is of high quality.

Die für eine Rohrleitung bestimmten Rohre erhalten neuerdings häufig im Herstellungswerk eine umkleidung <_ ta Kunststoff, wobei vor aller- Polyäthylen als Ausgang «material dient. Die Machisolierung der Rohrverbindungen auf der Baustelle, d. h. am oder im Rohrgraben, geht ebenfalls unter Verwendung von Kunststoff und zwar in Binden- und Bandagenform vonstatten.Intended for a pipeline pipes received recently frequently at the factory, a casing <_ ta plastic, serves as a starting aller- polyethylene "material. The mach insulation of the pipe connections on the construction site, ie on or in the pipe trench, is also carried out using plastic, namely in the form of bandages and bandages.

Bei dieser Nachisoliermethode unterscheidet man Varm- und Kaltverfahren. Wichtig für beide Machisoliermethoden ist wegen der Zielsetzung einer Abriegelung des Zutritts von Bodenflüssigkeit vollkommene Dichtigkeit des Bandmaterials selbst sowie seiner Überlappungsgebiete. Bei dem Kaltverfahren hat sich eine Schutzbinde auf der Basis synthetischer Kautschuke eingeführt, deren Überlappungsabschnitt in seinen beiden Lagen nach dam Wickeln dar Binden untrennbar miteinander verwächst.With this post-insulation method, a distinction is made between Varm and Cold process. This is important for both Mach insulation methods Because of the objective of blocking the entry of soil liquid, the strip material is completely impermeable itself as well as its areas of overlap. In the cold process has introduced a protective bandage based on synthetic rubbers, the overlap portion of which is in its two layers after the wrapping of the bandage inseparably fused together.

wicklungen von hoher Wasserdampfdichtigkeit in einem zweiten Arbeitsgang mit einer Folie aus Polyäthylen oder Polyvinylchlorid umwickelt.windings of high water vapor permeability in a second operation with a film made of polyethylene or polyvinyl chloride wrapped.

Man hat nun Versuche unternommen, Kombinationsbänder herzustellen, bei welchen der "mechanische Schutz" in Form von Kunststoff-Folien mit dem für den Korrosionsschutz im wesentlichen bestimmten Band unmittelbar verbunden ist. Bei dieser zwar vereinfachenden technischen Lösung erreicht man jedoch keine "Verwachsung" im Uberlappungsgebiet.Attempts have now been made to produce combination tapes, in which the "mechanical protection" in the form of plastic films with that for corrosion protection in the essential specific band is directly connected. Achieved with this technical solution that is simplistic However, there is no "agglomeration" in the overlap area.

Inhalt der vorliegenden Neuerung ist eine Ofeischichtenbandage, die aus einem inneren Band (l) auf der Basis synthetischer Kautschuke besteht. Dieses der Rohrleitung beim Wickeln zugekehrte Band ist mit einer zweiten Lage in Form einer Folie (2) oder einem Gewebe bzw. Vlies oder dergleichen aus synthetischer Faser, bzw. einer Kombination von Gewebe, Vlies oder dergleichen und Folie ausgestattet, welcher aussen ein Band (3) entsprechend der inneren Lage (l) aus synthetischem Kautschuk aufkaschiert ist. Auf diese Weise erreicht man beim Wickeln die für die Dichtigkeit der Umhüllung wichtige Verwachsung der beiden Lagen aus synthetischem Kautschuk und gleichzeitig den mechanischen Schutz durch die Zwischenlage in Folien- oder Gewebe- bzw. Vliesform oder in Gestalt einer Kombination von Folie und Gewebe. Die Folie besteht aus Kunststoff bzw. aus Metall oder einer Kombination von Kunststoff und Metall, wobei dieses Metall elektronegativer als das zu schützende metallische Objekt sein sollte.The content of the present innovation is an oven layer bandage, which consists of an inner band (l) based on synthetic rubbers. This the pipeline When winding facing tape is with a second layer in the form of a film (2) or a fabric or fleece or the like made of synthetic fiber, or a combination of fabric, fleece or the like and foil, which outside a band (3) corresponding to the inner layer (l) made of synthetic rubber is laminated. In this way, one achieves the seal for the winding the two layers of synthetic rubber and, at the same time, the mechanical intergrowth, which is important for the covering Protection through the intermediate layer in the form of a film or fabric or fleece or in the form of a combination of film and Tissue. The film consists of plastic or metal or a combination of plastic and metal, with this metal is more electronegative than the one to be protected metallic object should be.
