RIT Team P13656: Agitator Redesign for Corrosive Environment - CTI Meeting

March 11th, 2013MSD II

Meeting Outline

• Current Project State– MSD I Recap and Project Changes– Feasibility Test Results

• Future Vision for MSD II– Testing Overview– Project Budget– Proposal– Additional Project Needs– Timeline– Deliverables

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 SetupEquipment Highlights

Model: SC-6Tank Capacity: 6 gallonsTank Material: 316L SSTank Dimensions: 13” x 13” x 12”Power: Standard 120V, 20AUltrasonic Power: 600 WTransducer Type: 40 kHz piezoelectricHeating Power: 1000 WLoudness (insulated): 80 dBFrequency Generator Output: 40.8 kHzCost: $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 stock.

• Temperature of bath is 150F

– 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

Feasibility Test Results

Total Time in Ultrasonic Bath: 73 min

Initial Coating Thickness: _____ microns

Final Coating Thickness: avg. ____microns

Future Vision for MSD II

• Testing Overview• Project Budget• Proposal• Additional Project Needs• Timeline• Deliverables

Testing Overview

• First Round– Variable Testing– Corrosion Testing– Capillary Test

• Solution Testing• Second Round– Scale-up Test

First Round Testing (Variable, Corrosion, and Capillary Tests)

• Details….sample size, data collection methodology (triangle), error mitigation, variables, etc.

• Will be conducted in RIT lab using small Branson ultrasonic cleaning unit

Second Round of Testing(Solution and Validation Tests)

• Conducted using larger scale production unit

• Test outline and objectives….what we’re planning on analyzing and initial thoughts on tank optimization
