Trial #2
To evaluate selected product on supplied parts.
One product was selected from the on-site visit. The product was diluted to 5% using DI water in 2000 ml beaker and heated to 130 F in a Branson 3510 ultrasonic tank filled with water. The solution was degassed for 5 minutes. A small, slotted basket was filled with dirty parts and immersed into the beaker. Parts were cleaned for 2 minutes using 40 kHz ultrasonic energy. Following cleaning, the parts in the basket were immersed into a two-stage heated tap water rinsing process. Parts were agitated for 15 seconds in each of the two rinse beakers. The cleaned and rinsed parts were then emptied into a large basket with slots to dry. In addition, excess water was removed by both shaking the larger basket of parts and through compressed-dry air at room temperature for 1 minute. Observations were made. Parts were sent back to client for final evaluations.
The parts looked very clean after two minutes of cleaning. No visible signs of oil were present. Likewise, following wipe testing with a white swab no oil was present. Photographs were also taken of each stage of the cleaning process.
Sea Wash Blue at 5% for two minutes removed most of the oil that was on the parts. Parts were sent back for client approval.
