ABRASIVE BRISTLE, METHOD FOR THE MANUFACTURE THEREOF, BRUSH WITH ABRASIVE BRISTLES AND METHOD FOR THE SURFACE TREATMENT OF A WORKPIECE WITH A BRUSH HAVING ABRASIVE BRISTLES

摘要

For the manufacture of an abrasive bristle, a plastic material is melted, and a granular material made of abrasive particles is mixed into the melt. The melt is extruded together with the abrasive particles into a filament, and the filament is subsequently treated and cut up. The plastic material may be a high-temperature-resistant polymer with a continued use temperature of ≧150° C. and for the melt with the abrasive particles to be extruded at a temperature of ≧280° C. A brush equipped with corresponding abrasive bristles can be used for the surface treatment of a workpiece, whereby the brush is rotated with a speed in the range of 3,000 rpm to 12,000 rpm and is brought into contact with the surface to be treated.

主权项

1. A method for manufacture of an abrasive bristle, the method comprising:
melting a plastic material and mixing a granular material made of abrasive particles into the melt; extruding the melt with the abrasive particles into a filament; and treating and cutting the filament, the plastic material comprising a high-temperature-resistant polymer with a continued use temperature greater than or equal to 150° C., and the melt with the abrasive particles being extruded at a temperature greater than or equal to 280° C.
