CA 2748511

An abrasive disc includes a backing layer on a first major surface, a water- impermeable abrasive layer on a second major surface, and a water-absorbable, compressible, resilient, porous foam layer sandwiched in between the backing layer and the abrasive layer. The disc further includes a plurality of perforations. The disc is used to abrade a surface. Fluid is absorbed into the abrasive disc. The fluid is then released to the surface by compressing the abrasive disc against the surface in an abrading motion. The fluid is allowed to mix with and absorb surface swarf; and compression on the abrasive disc is released, reabsorbing the fluid and trapping swarf inside the disc.

L'invention porte sur un disque abrasif, qui comprend une couche de support sur une première surface principale, une couche abrasive imperméable à l'eau sur une deuxième surface principale, et une couche de mousse poreuse, élastique, compressible, absorbant l'eau, prise en sandwich entre la couche de support et la couche abrasive. Le disque comprend en outre une pluralité de perforations. Le disque est utilisé pour abraser une surface. Du fluide est absorbé dans le disque abrasif. Le fluide est ensuite libéré à la surface par compression du disque abrasif contre la surface dans un mouvement d'abrasion. On laisse le fluide se mélanger avec les copeaux de surface et les absorber ; et on détend la compression sur le disque abrasif, ce qui provoque une réabsorption du fluide et piège les copeaux à l'intérieur du disque.
