Embodiment 1

[0107] Using equipment such as that available from the Rando Machine Company of Macedon, New York under the trade designation "RANDO WEBBER", a product having a thickness of about 677 g / m was formed. 2 A lofty, random airlaid web of a blend of 90% F1 and 10% F2 by weight. The web was further needle punched, rolled in a knitting machine, and a prebond coating with the composition shown in Table 1 was applied to the airlaid fabric to achieve about 274 g / m 2 dry additional weight. The prebond is then cured in an oven. At about 579g / m 2 A make layer precursor having the composition shown in Table 1 was applied to a prebonded airlaid web. The formed urea-formaldehyde particles MIN at about 347g / m 2 An additional weight of 100 Å was applied to the uncured primer layer precursor, via particle drops, on each side of the primer-coated web. The abrasive-coated web is then cured in an oven. A size layer precursor of the composition shown in Table 1 was applied to the abrasive-coate...

Embodiment 2

[0111] Using "RANDO WEBBER" equipment to form with about 293g / m 2 lofty, random airlaid web of F3 by weight. The web is further needled into the scrim in the knitting machine, rolled, and rolled at about 290 g / m 2 A make layer precursor having the composition shown in Table 1 was applied to the airlaid fabric at a dry add-on weight of . The formed urea-formaldehyde particles MIN at about 323g / m 2 An additional weight of 100 Å was applied to the uncured primer layer precursor, via particle drops, onto the top side of the primer-coated web. The abrasive-coated web is then cured in an oven. A size layer precursor of the composition shown in Table 1 was applied to the abrasive-coated web to provide about 258 g / m 2 Additional weights of dry size layers were added and the additional layer precursors were subjected to final curing in an oven. Figure 10 is a photograph of the fibrous abrasive article of the present invention. Figure 11 and Figure 12 Photographs of the fibrou...

Embodiment 3

[0113] Will be commercially available from 3M Company under the trade name 3M SCOTCH-BRITE SURFACE CONDITIONING DISC ACRS but without a slurry coating weight of about 798 g / m 2 The airlaid needle punched nonwoven fabric was further coated with the make coat precursor having the composition shown in Table 1 at about 355 g / m 2 The dry add-on weight of 100% is applied to airlaid, punched and coated fabrics. The formed urea-formaldehyde particles MIN at about 226g / m 2 An additional weight of 100 Å was applied to the uncured primer layer precursor, via particle drops, onto the top side of the primer-coated web. The abrasive-coated web is then cured in an oven. A size layer precursor of the composition shown in Table 1 was applied to the abrasive-coated web to provide about 246 g / m 2 Additional weights of dry size layers were added and the additional layer precursors were subjected to final curing in an oven. Figure 13 is a photograph of the fibrous abrasive article of the pres...

Abstract

The present disclosure provides an abrasive article. The abrasive article includes a base. The abrasive article also includes a plurality of soft-shaped abrasive particles distributed around the base.

Description

Background technique [0001] Abrasive articles such as abrasive belts, abrasive sheets, and grinding wheels can be used to abrade workpieces. However, some workpieces are constructed of multiple materials. Typical abrasive articles are not capable of selectively abrading a single material of a workpiece. Accordingly, there is a need to develop abrasive articles capable of selectively abrading workpiece materials. SUMMARY OF THE INVENTION [0002] The present disclosure provides an abrasive article. The abrasive article includes a base. The abrasive article also includes a plurality of soft-shaped abrasive particles distributed around the base. [0003] The present disclosure also provides a method of using the abrasive article. The abrasive article includes a base. The abrasive article also includes a plurality of soft-shaped abrasive particles distributed around the base. The method includes contacting the abrasive article with a workpiece. The method also includes m...
