Trial Number 7

Trial Purpose:

To evaluate a client requested product for cleaning buffing compounds from their brass parts.

Date Run:

12/11/2006

Experiment Procedure:

One product was diluted to two concentrations, 5 and 10% using DI water in 250 ml beakers. Solutions were immersed in a water bath heated to 130 F and degassed using a Branson 3510 ultrasonic tank for five minutes. Six parts were immersed in each solution and cleaned with 40 kHz ultrasonic energy. Parts were rinsed in a tap water spray for 15 seconds at 120 F and dried using room temperature air for 30 seconds. Visual observations were made for both sets of cleaned parts and compared to each other.

Trial Results:

Concentration Observation
5% The buckles looked very clean
  The stripes also looked very clean
  One of the bars still had some buffing compound remaining.
   
10% The buckles looked very clean
  The stripes also looked very clean
  One of the bars still had some buffing compound remaining -
  less than the 5%

Success Rating:

A follow up test, usually based on company input.

Conclusion:

The Hubbard Hall Ultrasoak 127 was very effective on most of the part types cleaned. Both the 5 and 10% dilutions had some trouble removing all the buffing compound from the back of the double bars.
