Definitions

  • the invention relates to a method according to the preamble of patent claim 1.
  • the desired metal soaps only form part of the impregnation mixture and several impregnation processes with subsequent drying or removal of excess impregnation mixture are usually required (e.g. by rotating the impregnated grinding wheel and ejecting excess portions of the impregnation mixture).
  • suitable solvents water or organic solvents
  • ceramic-bonded disks with a relatively large pore volume primarily a structure 7 or larger, are treated with metal soaps until the volume of the metal soaps introduced corresponds to at least 5% of the total volume of the grinding disk.
  • plastic-bonded grinding wheels provided that they have a corresponding structure.
  • Montanic acids C 22 ... to C 34 with melting points above 80 ° C. can also be used as fatty acids, as can hydroxy compounds of the listed compounds, 12-oxystearic acid being mentioned as an example.
  • the possibility according to the invention of introducing metal soaps into correspondingly porous grinding wheel bodies is that the soap is formed in the grinding wheel or in the honing body by chemical reaction. This has the advantage that only small amounts of water have to be removed, and that the soaps are obtained in a compact form, so that only a single impregnation may be sufficient. Furthermore, the addition of small amounts of binder can be dispensed with here.

Claims (6)

1. Procédé pour améliorer le rendement de meulage des outils de meulage et de pierrage à liant céramique ou plastique par l'utilisation de savons métalliques dans les porosités des outils de meulage et de pierrage, en particulier de sels de l'acide stéarique avec des métaux mono- ou polyvalents, caractérisé en ce que le savon métallique est formé à l'intérieur des porosités à partir d'un mélange réactionnel exempt de savons métalliques constitué d'acide gras ou d'un composé d'hydroxyde-acide gras ou d'un savon d'ammonium de la formule générale (CnH2n+1-COOH) avec n 211 et d'un composé métallique sélectionné dans le groupe des oxydes ou hydroxydes ou carbonates, en liquéfiant le mélange réactionnel par échauffement et en l'introduisant sous vide dans les porosités, après quoi la réaction pour la formation du savon métallique se déroule avec apport de chaleur supplémentaire, suivie de l'expulsion des produits de réaction secondaires.
2. Procédé selon la revendication 1, caractérisé en ce que le composé métallique est de l'hydroxyde de sodium et qu'un échauffement au-delà de 71°C provoque dans les porosités la formation de stéarate de sodium et d'eau selon la formule de réaction suivante:
Figure imgb0008
3. Procédé selon la revendication 1, caractérisé en ce que le mélange réactionnel est constitué d'un bain de stéarate d'ammonium et de la quantité stoechiométrique de l'oxyde métallique ou de l'hydroxyde métallique.
4. Procédé selon la revendication 3, caractérisé en ce que l'hydroxyde métallique est du LiOH, ce qui conduit à la réaction suivante:
Figure imgb0009
5. Procédé selon la revendication 1, caractérisé en ce que le composé métallique est sélectionné dans le groupe des oxydes, hydroxydes ou carbonates des métaux des premiers et deuxième groupes principaux et respectivement secondaires de la classification périodique des éléments.
6. Procédé selon la revendication 1, caractérisé en ce que le mélange réactionnel est constitué d'acide stéarique ou d'acide hydroxystéarique ou de stéarate d'ammonium et d'un composé métallique.
