What is the Bristle Blasting Process?

Bristle Blasting is a new process that uses a specially designed
rotary bristle tool for achieving both corrosion removal and an
anchor profile.

How does the tool perform blasting operations?

The rotating bristles are DYNAMICALLY TUNED to the power
tool, which results in impact and immediate retraction of bristle
tips from the corroded surface (see high speed photography).

How is this process similar to the abrasive grit blasting
process?

The bristle tips are designed to strike the corroded surface with
kinetic energy that is equivalent to grit blast media, thereby
generating a texture and visual cleanliness that mimics the grit
blasting process

Process Description and Principles of Operation
The bristle blasting process is a new innovation that both removes corrosion and generates an anchor profile by using a
specially designed rotary bristle tool. This tool consists of hardened wire bristle tips that are bent forward and
dynamically tuned to a hand-held power tool which operates at approximately 2,500 rpm. The mechanical
principles upon which the bristle blasting tool is based are summarized as follows: Bristle tips are designed to strike the
corroded surface with kinetic energy that is equivalent to standard processes that use grit blast media. Immedia-tely after
the bristle tips strike the corroded steel surface, they retract (i.e., "rebound") from the surface, which re-sults in both
corrosion removal and a micro-indentation that exposes fresh surface. Consequently, surfaces that have been treated by
the bristle blasting tool have a texture and visual cleanliness that mimics those obtained by traditional grit blasting
processes.

Common Applications
Although the bristle blasting process is ideally suited for spot-repair applications, it can also be readily applied to larger
surface areas where the use of other metal cleaning processes may be prohibitive or impractical. The pro-cess provides an efficient means for the removal of corrosion, mill scale, defunct protective coatings, and for post-weld cleaning operations. These applications frequently arise in a wide range of fabricating and infrastruc-ture-support operations, such as onshore/offshore well drilling installations, bridge refurbishment, the fabri-cation and repair of naval/marine vessels,
and industrial maintenance applications.
