BeschreibungDescription
Es ist schon seit langem bekannt, Behälter, Rohrleitungen, Rührorgane, Pumpen und dergleichen, die mehr oder weniger großen Abrasionen ausgesetzt sind, mit einem entsprechenden Oberflächenschutz zu versehen, wobei Ausmauerungen oder Schutzüberzüge aus einer dicken Weichgummischicht eingesetzt werden.It has long been known to provide containers, pipelines, agitators, pumps and the like, which are exposed to more or less severe abrasion, with appropriate surface protection, using brick linings or protective coatings made of a thick layer of soft rubber.
Diese bekannten Abrasionsschutzeinrichtungen weisen relativ kurze Standzeiten auf, was zu häufigen Anlagenausfallzeiten führt. Bei Ausmauerungen ist noch zusätzlich von Nachteil, daß eine entsprechende Dimensionierung der Teile und damit zusammenhängend Gewichtsprobleme zu berücksichtigen sind und daß die Entsorgung der Ausmauerung bergmännische Arbeit erfordert.These known abrasion protection devices have a relatively short service life, which leads to frequent system downtimes. Another disadvantage of brick linings is that the appropriate dimensioning of the parts and the associated weight problems must be taken into account and that the disposal of the brick lining requires mining work.
Es wurden nun überaus standfeste und preiswerte Schutzüberzüge gegen Abrasion gefunden. Der erfindungsgemäße Abrasionsschutz auf der Basis von Gummi ist dadurch gekennzeichnet, daß an der Oberfläche der Gummischicht Aluminiumoxid (Al2O3) anwesend ist. Das Aluminiumoxid ist vorzugsweise in Form von Plättchen in der Gummierung eingebettet. Die Form der Plättchen ist an sich nicht kritisch; es können quadratisch, rund, rechteckförmig, trapezförmig, dreieckig und dergleichen ausgebildete Al2O3- Plättchen eingesetzt werden. Die Dicke der Plättchen beträgt im allgemeinen 0,5 bis 4 mm, vorzugsweiseExtremely stable and inexpensive protective coatings against abrasion have now been found. The rubber-based abrasion protection according to the invention is characterized in that aluminum oxide (Al 2 O 3 ) is present on the surface of the rubber layer. The aluminum oxide is preferably embedded in the rubber coating in the form of platelets. The shape of the platelets is not critical per se; square, round, rectangular, trapezoidal, triangular and similarly shaped Al 2 O 3 platelets can be used. The thickness of the platelets is generally 0.5 to 4 mm, preferably
1 bis 3 mm. Sie werden in das Gummimaterial eingebettet und einvulkanisiert. Das sehr harte Aluminiumoxid übernimmt die Abrasionsaufgaben und die Gummierung den Schutz gegen beispielsweise sauren und basischen Betrieb. Da die Al2O3-Plättchen starre Gebilde darstellen, sind zur Erreichung der erforderlichen Biegsamkeit der mit den Plättchen versehenen Gummierung mehr oder weniger große Abstände zwischen den Plättchen vorzusehen. Aus dem gleichen Grund wird man, je nach Anwendung des fertigen Abrasionsschutzes, die Größe (Durchmesser) der Plättchen auswählen und kleine, mittlere oder größere Plättchen einsetzen. Die Oberfläche der Gummischicht ist demnach vorzugsweise bis zu 80 bis 95 % mit Al2O3-Plättchen besetzt. Das Einpressen der Plättchen in die Gummischicht erfolgt bei einer Temperatur von 120 bis 150 "C. Die Gummischicht hat in der Regel eine Dicke von 2 bis 6 mm.1 to 3 mm. They are embedded in the rubber material and vulcanized in. The very hard aluminum oxide takes on the abrasion tasks and the rubber coating provides protection against, for example, acidic and basic operation. Since the Al 2 O 3 platelets are rigid structures, more or less large gaps must be provided between the platelets in order to achieve the required flexibility of the rubber coating provided with the platelets. For the same reason, depending on the application of the finished abrasion protection, the size (diameter) of the platelets is selected and small, medium or large platelets are used. The surface of the rubber layer is therefore preferably covered with Al 2 O 3 platelets up to 80 to 95%. The platelets are pressed into the rubber layer at a temperature of 120 to 150 "C. The rubber layer is usually 2 to 6 mm thick.
Der erfindungsgemäße Abrasionsschutz weist eine Reihe von Vorteilen auf. So hält er auch hohe Abrasionsbedingungen aus. Er gewährleistet also lange Standzeiten und dementsprechend minimierte Ausfallzeiten. Er ist trotz des an der Oberfläche eingebetteten Aluminiumoxids gut handhabbar und kann auf Behälterwände, Rohrleitungen, Pumpen, Rührer und dergleichen ohne Schwierigkeiten aufgebracht werden. Der erfindungsgemäße Schutzüberzug auf der Basis von Gummi kann ferner mit den üblichen Methoden hergestellt werden, und er ist auch sehr preiswert.The abrasion protection according to the invention has a number of advantages. For example, it can withstand high abrasion conditions. It therefore guarantees long service lives and minimizes downtime. Despite the aluminum oxide embedded in the surface, it is easy to handle and can be applied to container walls, pipes, pumps, stirrers and the like without difficulty. The protective coating based on rubber according to the invention can also be produced using conventional methods and is also very inexpensive.
Die Erfindung wird nun anhand von beispielhaften Ausführungsformen, dargestellt in einer Zeichnung mit den Figuren 1 und 2, noch näher erläutert, wobei jede Figur in Form einer schematischen Schnittansicht gestaltet ist.The invention will now be explained in more detail using exemplary embodiments, shown in a drawing with Figures 1 and 2, each figure being designed in the form of a schematic sectional view.
Der Abrasionsschutz nach Figur 1 besteht aus einer Gummischicht 1, in deren Oberfläche rechteckformige Al2O3-Plättchen 2 in geringem Abstand voneinander mit Hilfe von Haftbohrungen 3 eingebettet sind.The abrasion protection according to Figure 1 consists of a rubber layer 1, in the surface of which rectangular Al 2 O 3 platelets 2 are embedded at a short distance from one another by means of adhesive holes 3.
Figur 2 zeigt einen für eine Rohrauskleidung vorgesehenen Abrasionsschutz. Die rechteckformigen Al2O3-Plättchen sind auf der Oberfläche der gerundeten Gummibahn 1 eingebettet und in geringem Abstand voneinander angeordnet.Figure 2 shows an abrasion protection provided for a pipe lining. The rectangular Al 2 O 3 plates are embedded on the surface of the rounded rubber sheet 1 and arranged at a short distance from one another.
