Definitions
- 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.
- 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.
- filler the so-called filler
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the Grinding wheel can also be used for finer surfaces Have abrasives above P1000.
- an abrasive becomes Alox, aluminum oxide, for grinding body panels preferred because the generated roughness for the subsequent filler application is particularly suitable.
- 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.
- 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:
- 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.
- Grid line abrasive material with finer grit 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.
