Definitions
- Backed abrasives are generally described in manufactured in such a way that on a flexible carrier, like paper, fabric or vulcanized fiber, a binder, such as animal glue or phenol-formaldehyde resin into which the abrasive grain is electrostatic or is scattered mechanically. After curing this so-called basic bond is the abrasive grain in its position fixed on the carrier. Then it will a second bond layer, the so-called cover bond, applied, also from animal glues or resols mixed with fillers. This second bond layer gives the abrasive grain its final firm anchoring on the beam.
- the use of different types of fillers in binding systems for abrasives such as those mentioned Glues or resols happen for various reasons. So in addition to stretching through cheaper fabrics like e.g. B. chalk, also improving each Drying and curing processes and an improvement the mechanical properties of the bonds.
- grinding active fillers such as. B. cryolite or potassium fluoroborate, one depending on the respective material, more or less great improvement in grinding performance achieved because these substances the grinding process positive influence.
- the addition takes place in finely ground form in the cover binding.
- the maximum processable size is determined by the usual mixing and application procedures determined.
- DE-PS 3 112 954 C2 grinding active substances in solid abrasives also in the form of granules or Pellets used.
- the object of the invention is to provide an abrasive to show the questionable type, which is not the aforementioned Is subject to restrictions and still with a lower proportion of abrasive grain and thus reduced Cost grinding performance comparable to that Provides abrasives according to the prior art.
- This task is performed on the abrasive after Preamble of claim 1 solved in that the Additional grains about the same grain size as that Have abrasive grains and one or more of the a lower hardness than the abrasive grains Fabrics chalk, cryolite, dried aluminum oxide suspension or single crystal magnesium oxide. It was surprisingly found that the grinding performance significantly increased through this training can be. The additional grains do not have to be possess abrasive properties. So it's for them Additional grains no particular hardness required. As well are grinding active properties, such as. B. at Known cryolite is not required.
- the spatial arrangement of abrasive grain and Additional grain selected so that the tips of the abrasive grain and the additional grain lie in one plane if possible and so that they can be used simultaneously in the grinding process.
- the advantage of the abrasive according to the invention is not only a matter of considerable savings expensive abrasive grain, but above all in one significant increase in grinding performance.
- the application is according to the usual state of the art of additional grains in the size of the used Abrasive grains together with the cover binding only under major difficulties possible, so that the invention Abrasives advantageously produced in this way is that the additional grains used with the Abrasive grain are mixed and this mixture is electrostatic or mechanically sprinkled into the basic weave becomes.
- the two components also in two or more consecutive Scattering processes are applied.
- the cover binding is then roller-coated applied, these 50% by weight a phenol resole and 50% by weight synthetic Cryolite with an average particle size of 15 ⁇ m consists.
- the amount applied is 460 g / sqm.
- the cover binding is also cured in a known manner.
- the abrasive thus obtained is then made flexible and to an endless belt of 2000 mm in length and 50 mm made up.
- the test is carried out by grinding against a rotating one Round rod of 30 mm diameter made of C 45, material no. 1.0503 according to DIN 669 under a load of 35 N, grinding at intervals of 5 min each becomes.
- the test is ended when the sanding per Interval drops below 50 g.
- a test tape according to Example 1 is produced, with a mixture of 50 vol .-% zirconium corundum of grain size 36 (according to AINSI) and 50 vol .-% one on the same Grain size sifted on sifted chalk as additional grain becomes.
- the applied amount is 680 g / qm.
- the test is carried out as in Example 1 under a load of 40 N. The test is ended when the sanding drops below 100 g per interval.
- a test tape according to Example 1 is produced, however, a mixture of 60 vol .-% cryolite granules as additional grain, sieved to grain size 36 and 40 Vol .-% zirconium corundum is scattered.
- the test is done against a rotating round rod of 30 mm diameter made of stainless steel (material no. 1.4301 rolled and quenched, ADW 2, DIN 17440 - 7/85). It is in eight intervals of 5 minutes each, a total sanding 1203 g achieved.
- Sprinkled with pure zirconium corundum Comparative band achieved in the same period a sanding of only 660 g.
- a test tape according to Example 1 is produced, however, a mixture of 55 vol .-% zirconium corundum Grain size 36 and 45 vol .-% of a dried, finely divided Alumina suspension according to DE-PS 3 604 848 C2 as additional grain sifted to the same grain size, is scattered.
- the tape is completed as in the previous examples.
- the service life of the abrasive according to the invention is 25 intervals compared to only 12 intervals of the comparison tape.
- a test tape according to Example 1 is produced, with a mixture of 50 vol .-% sintered corundum grain size 36 and 50 vol .-% monocrystalline magnesium oxide the same grain size is scattered as additional grain.
- the test is carried out against a rotating round rod from 30 mm diameter made of 42 CrMo4 (material no. 1.7225). 20 intervals of 1 min each are ground under a pressure of 35 N. The removal is 642 g; a comparison belt with pure sintered corundum only grinded to 545 g in the same period.
