Definitions

  • the present invention relates to a method for processing surfaces of structures such as sheets, plates and the like, in which the surface is prepared by grinding or brushing for subsequent coating, oxidation or gluing, and a structure produced therewith in accordance with the preambles of claims 12 and 13.
  • surfaces are treated by applying a protective layer, for example in the form of lacquer as paint.
  • a protective layer for example in the form of lacquer as paint.
  • the properties of surfaces can also be changed by applying a coating of a different metal, protected against corrosion.
  • the surface is contaminated as a result of the inherent peculiarities of the production, for example in the case of metal sheets, with a fat-containing layer which was applied during the rolling process.
  • This layer subsequently prevents perfect adhesion of paints as well as artificial oxidation, whether in the air or in a plunge pool with a reaction liquid.
  • these so-called rolling greases are removed by means of solvents in order to achieve better adhesion.
  • a roughening of a surface has also already been proposed by the method according to GB-A-495 421.
  • a harder fabric is pressed in and then removed again. This also inevitably creates harmful hardening of the surface.
  • the object of the invention is to provide a method for processing the surface of structures, such as solid plates and sheets and the like, by means of which the surface forms an excellent base for subsequent coating operations without notable hardening. Another task is to create a structure that meets these requirements.
  • impressions 5 have approximately the same size and thus the same depth and they dominate the appearance of the surface and give it a more regular structure; in the case of thin sheets, they have a depth which is equal to or less than the average depth of the grooves 1 and 3. With thicker structures, the depth of penetration can exceed the average depth of the grooves.
  • the grooves 1,3 run at an angle of 90 °; they can also be generated in an angular range of 90 ° ⁇ 45 °.
  • the impressions 5 shown in FIG. 2 have been applied deeper than necessary for better visibility.
  • a plurality of knurled rollers arranged in series with the same or different tip design and arrangement are used, thus achieving a surface-covering treatment of the surface.
  • the knurled tips can also be conical instead of pyramid-shaped.
  • FIG. 3 which has been recorded in abbreviated form with a "Perthometer” roughness measuring device from Feinprüf GmbH, D-3400 Göttingen, and represents a tactile section of the surface in which the roughness depths due to the crosswise grinding process can be seen, the structure of the Surface can be read out.
  • the surface of the sheet is divided into a multiplicity of intersecting mountains 2 and valleys 4 by the cross grinding.
  • the surface provided with a cross-cut was subsequently machined with a knurling tool of the type mentioned above.
  • This machining process allows the tips to have a precisely adjustable roughness depth d without the base material being significantly hardened by the impressions of the tips of the knurling tool.
  • the larger differences between the mountains 2 and valleys 4 result in a large surface on the flanks, which thereby enables excellent adhesion of paints or oxidation. This is particularly so because the minimum width of the valleys 4 in the resulting gaps is large enough for the coating material or oxidizing agent to enter safely to guarantee.
  • the formation of undesired caverns is excluded.
  • the pitch can be chosen between 0.2 and 04 mm.
  • several knurled passes can of course also be carried out or several knurled rollers with identical or different tips and penetration depths can be guided in a row. This enables an optimized structure of surface enlargement.
  • the tips are preferably displaced both transversely and lengthwise, so that a regular image is again formed.
  • the impressions mutually influence one another and the displaced material can also escape into the impressions previously generated.
  • the depth of penetration of the knurled tips into the material surface corresponds to the mean depth of the grooves 1.3; it can also be somewhat smaller or larger and depends on the material, its thickness and the surface and the type of coating.
  • the flat area at the bottom of the impressions 5 results from the slight flattening of the knurled tips in order to minimize their wear. The flat areas are only visible because of the 100x magnification.
  • metal surfaces be prepared for coating in this way.
  • plastic plates or plastic surfaces of plates to which, for example, a metal layer or a metal coating is to be applied with good adhesion can be advantageous. If the requirements for the liability of the coating are less stringent, grinding can also be replaced by a brushing process.
  • a 0.7 mm thin, smooth sheet 9 made of oxygen-free roofing copper is longitudinally sanded in two passes with a sanding belt from SIA AG, 8500 Fettfeld, Switzerland, type 1920, SIARAL F, corundum paper on linen, grain size 80.
  • the speed of the sanding belt compared to the copper sheet at a surface pressure of approx. 0.7 bar is 30 m / s.
  • the maximum depth of the grooves is 0.3 mm.
  • the ends of the tips 11 can be flattened (cf. impressions in FIG. 4).
  • the tips 11 therefore penetrate mainly into the groove flanks and not into the lower-lying sheet metal area, which has been left untouched by the grinding process, and break up the flanks of the mountains 2 that were previously smoothed by partial melting due to the resulting pushing forces, so that microscopic gaps at the impressions arise, the width of which is of the order of a few hundredths of a millimeter.
  • the knurled roller 7 is displaced such that the tips 11 are placed and pressed in between the already existing impressions 5 in both the transverse and longitudinal directions.
  • the arrangement of the tips 11 on the surface of the roller 7 can be selected such that the center thereof approximately with the intersection in a first group A1, A2, A3 of equidistant parallel lines with the same or different equidistant distances at an angle delta of 90 ° ⁇ 45 ° parallel straight lines of a second group B1, B2, B3, .. coincide and the equidistances of this straight line correspond to approximately one to five times the dimension of the impressions 5 taken in the longitudinal direction.
  • a sheet 9 prepared in this way, which is coated with a protective lacquer, ensures a surprisingly better adhesion of the layer compared to conventional surface processing, which withstands high mechanical stresses and weather influences.
  • a roller with a smooth jacket can also be used.
  • a sheet metal or the like covered with points is placed around the jacket of the roller and connected to it. The connection can be made in such a way that a new sheet is drawn on when the knurled tips wear out.
