Trial Purpose:
To evaluate selected products on third set of spindles using ultrasonic cleaning
Date Run:
05/11/2006Experiment Procedure:
One of the three products was diluted to 5% using DI water and the other was diluted 50% in 600 ml beakers. The cleaning solutions were heated to 130 F in an ultrasonic tank.
The supplied parts were coated with a water based paint mixture. One end of spindle was immersed into a cleaning product and cleaned for 30 minutes using a 40 kHz ultrasonic tank. Visual observations were made at 5, 10, 20 and 30 minutes. After the cleaning, the part was rinsed in a tap water spray for 15 seconds at 120 F and air dried for 30 seconds at room temperature. The parts were then rubbed with a gloved hand to determine how easily the paint could be removed.
Trial Results:
The products removed most of the paint from the supplied parts. The observations made for each product are listed in the table below.

Success Rating:
A follow up test, usually based on company input.Conclusion:
Both products removed most of the oil and paint from the spindles after 30 minutes of ultrasonic cleaning.
