To evaluate baking soda blasting as a method to clean the brushed aluminum from trains.
Date Run:
03/09/1999
Experiment Procedure:
Two brushed aluminum parts were brought to a facility in Springfield that operates an Armex Cleaning and Coating Removal System. The media being used with this blasting equipment was Arm & Hammer Baking Soda from Church & Dwight Co. The system operates with a pressure of 100 psi and a delivery of 150 cubic feet per minute of the baking soda. The part was placed into the cleaning chamber. The time required to clean the parts was under 15 seconds. Parts were rinsed for 10 seconds with a tap water spray.
Parts were easily cleaned using the Armex system. The parts have been returned to the client for inspection.
Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
Conclusion:
Baking soda blasting could be used to provide an initial base line cleaning for the brushed aluminum. Additional product literature has been included with this report.
