Current Project State
Recap of MSD I Project Changes
• Project scope changed from
part cleaning via mechanical
agitation system to the use
of ultrasonics
• Budget increased in
anticipation of more costly
purchases
Pre-Winter Hiatus
• Waiting for test results from
visit to Jamestown at end of
last meeting
Feasibility Test Setup
Equipment Highlights
Model: SC-6
Tank Capacity: 6 gallons
Tank Material: 316L SS
Tank Dimensions: 13” x 13” x 12”
Power: Standard 120V, 20A
Ultrasonic Power: 600 W
Transducer Type: 40 kHz piezoelectric
Heating Power: 1000 W
Loudness (insulated): 80 dB
Frequency Generator Output: 40.8 kHz
Cost: $3,462.00 (Peter quote)
Warranty: 5 yrs on transducers, 1 yr on
SS tank
Tank Conditions
•
•
•
Solution Used: SevereClean _____
– Composition not known
Amount of Solution: 4 gallons
Initial Bath Temperature: 137-140F
– Heating elements do not remain
on the entire time. After the
transducers are turned on, the
energy from the 600 watt sonics
transfers heat energy to the
bath.
Feasibility Test Procedure (just discuss)
•
•
Degassing time: 7 min
Part placed in tank with thick rubber
glove in a ‘clean side up’ orientation
(because transducers mounted on
bottom of tank)
– 1st removal from tank (and
inspected visually); time: 16 min
– 2nd removal from tank; time: 17
min
• Turning tinted orange/red on
the sides
– 3rd removal from tank; time: 22
min
• Comparing to one of the original
bar stock it looks shades lighter,
but obviously not completely
removed as compared to the
bare SS bottom face of the bar
– 4th removal from tank; time: 18
min
• Tested specimen is much lighter
in color, appears somewhat
polished
• The coating is not completely
removed, but we can tell
significant stripping has
occurred. We will now follow up
with a coating thickness check,
to evaluate the degree of
stripping.
– Total stripping time: 73 min (1 hr
13 min); degassing time was not
included
