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. Immediately after the bristle tips strike the corroded steel surface, they retract (i.e., "rebound") from the surface, which results 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.Understanding 3 key features of the
Bristle Blasting Process
Q: What is the Bristle Blasting Process?
A: Bristle Blasting is a new process that uses a specially
designed rotary
bristle tool for achieving both corrosion removal and an
anchor profile.
Q: How does the tool perform blasting operations?
A: The rotating bristles are DYNAMICALLY TUNED to the power
tool,
which results in impact and immediate retraction of bristle
tips from the
corroded surface.
Q: How is this process similar to the abrasive grit blasting
process?
A: 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.
