Wearable Abrasive Surfaces for Dry Applications
摘要:
Abrasive articles are disclosed that may be used in low speed dry sanding applications. The abrasive articles disclosed may be made entirely from abrasive materials or alternatively may be made by fastening abrasive surfaces to handles or tools. The abrasive articles of the present invention have abrasive surfaces with controlled wear rates that renew themselves during use. The self renewing abrasive surfaces of the present invention may be prepared by pressing a mixture of abrasive particles, hollow micro-particles and a minimal amount of binder together into a mold and subsequently allowing the binder to harden. The resulting abrasive articles are long lasting and may be made low in cost.
