Abstract

The grid line grinding material consists of a fabric layer (1) with a covering or resin and grinding grains. The crossing points (6) of the threads (3, 4) form grinding points spaced out in a grid over the surface (7) of the grinding material and leaving free points (8) at which there is no grinding effect. A gripping layer (10) on the grinding material makes it easier to handle. After the initial treatment and checking of the surface, the material is used manually to remove irregularities.

Description

Die Erfindung bezieht sich auf Gitterleinen-Schleifmaterial sowie auf ein Verfahren, insbesondere zur Nachbehandlung von kathodisch lackierten Oberflächen, bei denen das Gitterleinenschleifmaterial angewendet wird.The invention relates to grid line abrasive material and on a method, in particular for Aftertreatment of cathodically painted surfaces, at to which the wire mesh sanding material is applied.

Im Personenfahrzeugbau werden Karosseriebleche kathodisch tauchlackiert (Elektro-Coating), wobei eine Grundlackierung bis 30 mm Dicke erzeugt wird. Die Grundlackierung weist eine gewisse Rauhigkeit auf, in der eine weitere Lackschicht, der sogenannte Füller (Primer), gut haftet. Es können aber Rauhigkeitsspitzen vorkommen, die über den Füllerauftrag vorstehen und deshalb unerwünscht sind. Solche vorstehenden Rauhigkeitsspitzen werden üblicherweise vor dem Auftragen des Füllers weggeschliffen.Body panels are used in passenger vehicle construction cathodically dip-coated (electro-coating), one Base coat up to 30 mm thick is produced. The Base paint has a certain roughness in which another layer of paint, the so-called filler (primer), is good is liable. However, there may be roughness peaks that exceed head the filler order and are therefore undesirable. Such protruding roughness peaks are common sanded away before applying the filler.

Der Erfindung liegt die Aufgabe zugrunde, Gitterleinen-Schleifmaterial anzugeben, das sich in besonderer Weise für die Nachbehandlung von kathodisch lackierten Oberflächen vor dem Füllerauftrag eignet.The invention is based on the object Specify grid line abrasive material that is in special way for the after-treatment of cathodic painted surfaces before applying the filler.

Das Gitterleinen-Schleifmaterial umfaßt eine Gewebeschicht mit gitterförmig gewebten Fäden, die mit einem Überzug aus Harz und Schleifkorn versehen sind, wobei eine ausreichende Steifigkeit mit genügender Flexibilität zur Anpassung an zu überschleifende Oberflächen erzielt wird. Die überzogenen Gitterelemente bilden Kreuzungspunkte, welche die Schleifebene des Schleifmaterials bestimmen; der Schleifkornbesatz in der Schleifebene ist somit rasterhaft aufgebaut. Um das Gitterleinen-Schleifmaterial bequem an einem Kletthafthandpad oder einem Schleifteller zu halten, ist an der der Schleifebene gegenüberliegenden Seite der Gewebeschicht eine Kletthaftvelourschicht angebracht.The grid line abrasive material includes one Fabric layer with lattice-like woven threads, which with a Coating of resin and abrasive grain are provided, one sufficient rigidity with sufficient flexibility to Adaptation to surfaces to be smoothed is achieved. The Coated grid elements form intersection points, which the Determine the grinding plane of the abrasive material; the The abrasive grain in the grinding plane is therefore grid-like built up. Around the grid line sanding material comfortably holding a Velcro hand pad or a sanding pad, is on the opposite side of the grinding plane Fabric layer attached a Velcro velor layer.

Die rasterartig verteilten Schleifstellen bilden Inseln in der Schleifebene, die jeweils von "Freistellen" umgeben sind, in denen das Schleifkorn keine Wirksamkeit hat, weil es gegenüber der Schleifebene zurückgesetzt ist. Die Freistellen bilden gewissermaßen Lücken in der Schleifebene, in welche die Rauhigkeitsspitzen des Grundlacks eindringen können, so daß sie von den inselförmigen Schleifstellen seitlich erfaßt und weggeschlagen ("geköpft") werden können. Auf diese Weise ist es möglich, nur die Rauhigkeitsspitzen zu kappen, ohne die feine Grundrauhigkeit der Oberfläche zu beeinträchtigen.Form the grid-like distributed grinding points Islands in the grinding plane, each of "cut out" surrounded in which the abrasive grain has no effectiveness, because it is set back from the grinding plane. The Cutouts form gaps in the grinding plane to a certain extent, into which the roughness peaks of the base coat penetrate can so that they from the island-shaped grinding points can be gripped laterally and knocked away ("beheaded"). In this way it is possible to close only the roughness peaks cut without the fine roughness of the surface affect.

Die Dicke des kathodisch aufgebrachten Grundlacks ist nicht immer gleichmäßig, d. h. es kommen auch Bereiche mit zu dicker Lackschicht vor. Das neue Gitterleinen-schleifmaterial ist auch dazu geeignet, solche verdichten Lackbereiche zu bearbeiten, d. h. die Dicke zu reduzieren und dabei eine feine Grundrauhigkeit zu erzeugen, die in etwa der Grundrauhigkeit der übrigen kathodisch tauchlackierten Oberfläche entspricht.The thickness of the base coat is applied cathodically not always even, d. H. areas also come with thick layer of lacquer. The new grid line sanding material is also suitable for compacting such paint areas edit, d. H. reduce the thickness while doing one to produce fine basic roughness, which is roughly the same Basic roughness of the other cathodically dip-coated Surface corresponds.

Eine Gewebeschicht 1 ist zu einer Kreisform geschnitten, um eine Scheibe zu bilden, deren mittlere Ebene als Schichtebene 2 bezeichnet wird. Kunststofffäden oder Naturfäden 3, 4 sind miteinander zu einem Gitter verwebt und erstrecken sich teilweise oberhalb und teilweise unterhalb der Schichtebene 2. Das Gitter ist in Harz getränkt worden, dem Schleifkorn beigesetzt ist, so daß sich ein Überzug 5 über und zwischen den Gewebefäden 3, 4 gebildet hat. Nach Aushärten des Harzes vereinigt die Scheibe eine ausreichende Steifigkeit in der Schichtebene 2 mit genügender Flexibilität zur Anpassung an zu überschleifende Oberflächen, d. h. die Scheibe kehrt immer in ihre Ausgangslage zurück, wenn sie bei einem Arbeitsvorgang verformt worden ist.A fabric layer 1 is in a circular shape cut to form a slice whose middle level is referred to as layer level 2. Plastic threads or Natural threads 3, 4 are woven together into a lattice and extend partly above and partly below Layer 2. The grid has been soaked in resin, the abrasive grain is buried so that a coating 5 has formed over and between the fabric threads 3, 4. To Hardening of the resin combines the disc sufficiently Rigidity in layer level 2 with sufficient flexibility to adapt to surfaces to be smoothed, d. H. the Washer always returns to her starting position when she is at an operation has been deformed.

Die Gewebefäden 3, 4 bilden Gitterelemente, deren Kreuzungspunkte 6 in einer Ebene 7 liegen, welche die Schleifebene darstellt. Die Kreuzungspunkte 6 bilden ein Raster und sind von Freistellen 8 umgeben, an denen das Schleifkorn nicht zur Wirkung kommt.The fabric threads 3, 4 form lattice elements whose Crossing points 6 lie in a plane 7, which the Represents grinding plane. The crossing points 6 form one Grid and are surrounded by free spaces 8, where the Abrasive grain does not come into effect.

An der der Schleifebene 7 gegenüberliegenden Seite 9 ist an die Kunststoffgewebeschicht 1 eine Kletthaftvelourschicht 10 angebracht, beispielsweise mittels eines wasserfesten Klebers 11. Dadurch kann die Schleifscheibe besser gehandhabt werden, da man sie an einen Kletthafthandpad oder einen Schleifteller durch einfaches Auflegen anbringen kann.On the side 9 opposite the grinding plane 7 is a Velcro velor layer on the plastic fabric layer 1 10 attached, for example by means of a waterproof adhesive 11. This can remove the grinding wheel be handled better as you attach them to a Velcro hand pad or a sanding plate by simply putting it on can attach.

Die Größe der Schleifscheibe und die Körnung des Schleifmittels richten sich nach dem vorgesehenen Anwendungszweck. Es kommen Schleifscheiben mit einem Durchmesser zwischen 75 und 203 mm in Betracht. Auch andere geometrische Formen mit anderen Abmessungen sind nutzbar, weswegen allgemein von Gitterleinen-Schleifmaterial gesprochen werden kann. Zur Nachbehandlung von kathodisch tauchlackierten Oberflächen von Karosserieblechen wird eine Körnung im Bereich P180 bis P1000 bevorzugt. Die Schleifscheibe kann aber auch für feinere Oberflächen Schleifmittel oberhalb von P1000 aufweisen. Als Schleifmittel wird Alox, Aluminiumoxid, zum Schleifen von Karosserieblechen bevorzugt, weil die erzeugte Feinrauhigkeit für den nachfolgenden Füllerauftrag besonders geeignet ist. Für andere Anwendungszwecke können aber auch andere Schleifmittel verwendet werden, beispielsweise Siliciumcarbid (Sica), mit welchem ein schärferer Abrieb erfolgen kann. Alternativ wird bei Sica feineres Korn benutzt (im Verhältnis zu Alox), um Karosseriebleche zu schleifen.The size of the grinding wheel and the grit of the Abrasives are based on the intended Purpose. Grinding wheels come with one Diameters between 75 and 203 mm are considered. Others too geometric shapes with other dimensions can be used, which is why of lattice line abrasive in general can be spoken. For the after-treatment of cathodic Dip-coated surfaces of body panels become one Grain size in the range P180 to P1000 preferred. The Grinding wheel can also be used for finer surfaces Have abrasives above P1000. As an abrasive becomes Alox, aluminum oxide, for grinding body panels preferred because the generated roughness for the subsequent filler application is particularly suitable. For other applications can also use other abrasives are used, for example silicon carbide (Sica), with which can result in sharper abrasion. Alternatively, will Sica uses finer grain (in relation to Alox) to Grinding body panels.

Eine bevorzugte Anwendung des neuen Gitterleinen-Schleifmaterials besteht in der Nachbehandlung von kathodisch tauchlackierten Oberflächen von Karosserieblechen. Dabei geht man wie folgt vor:A preferred application of the new grid line abrasive material consists in the after-treatment of cathodic dip-coated surfaces of body panels. It goes do the following:

Die Gitterleinen-Schleifscheibe bzw. das Gitterleinen-Schleifmaterial wird über die gesamte lackierte Oberfläche gleichmäßig geführt, wobei Rauhigkeiten der lackierten Oberfläche, die über ein erwünschtes Maß hervorstehen, in die Freistellen 8 der Schleifscheibe geraten und von den Schleifstellen 6 abgeschliffen ("geköpft") werden. Nach diesem Überschleifen verbleibt eine lackierte Oberfläche mit feinen Rauhigkeiten. Die Oberfläche wird nunmehr mit einem fusselfreien Staubbindetuch abgewischt, um den entstandenen Staub von der lackierten Oberfläche zu entfernen. Der die Arbeiten ausführende Arbeiter überprüft die behandelte Oberfläche auf Unregelmäßigkeiten, insbesondere verdickte Bereiche des Untergrundlackes. Der Arbeiter führt die Schleifscheibe über solche verdickten Bereiche, um die Schichtdicke zu reduzieren. Die rasterartige Verteilung der Schleifstellen 6 auf der Schleifscheibe führt zu einer entsprechenden Grundrauhigkeit der überschliffenen Bereiche, wie es erwünscht ist. Der Fortgang der Arbeit wird immer wieder beobachtet, nachdem störender Staub weggewischt worden ist.The grid line grinding wheel or that Grid line abrasive material is painted over the entire Surface evenly guided, the roughness of the painted surface that is of a desired size protrude into the free spaces 8 of the grinding wheel and sanded from the grinding points 6 ("decapitated") become. After this smoothing, a lacquered remains Surface with fine roughness. The surface will now wiped with a lint-free dust cloth to the resulting dust from the painted surface remove. The worker carrying out the work checks the treated surface for irregularities, especially thickened areas of the base coat. The Worker guides the grinding wheel over such thickened Areas to reduce the layer thickness. The grid-like Distribution of the grinding points 6 on the grinding wheel leads to a corresponding basic roughness of the smoothed Areas as desired. The progress of the work will repeatedly observed after annoying dust wiped away has been.

Gitterleinen-Schleifmaterial mit feinerer Körnung (z.B. im Bereich P500 bis P1000) kann auch zum Überschleifen von Füllerlackierung benutzt werden. Zum gleichen Zweck kann auch Schleifmaterial, das für die Bearbeitung der kathodischen Tauchlackierung verbraucht ist, für die Füllerschicht weiterverwendet werden.Grid line abrasive material with finer grit (e.g. in the range P500 to P1000) can also be used for smoothing of filler paint. Can do the same also abrasive material used for machining the cathodic dip painting is used up for the Filler layer can continue to be used.
