Trial Number 3

Trial Purpose:

To evaluate vendor recommended cleaner for all three contaminants.

Date Run:

07/12/1999

Experiment Procedure:

The client supplied cleaner was made into a 5% solution by volume using DI water in 400 mL Pyrex beakers and heated to 130 F on a hot plate.
Three preweighed coupons were contaminated with the each of the three contaminants and weighed again. Coupons were cleaned using the client supplied cleaner using stir-bar-agitation for five minutes. Coupons were rinsed in 120 F tap water for 30 seconds and dried using a Master Appliance Corp, Hot-air gun model HG-301A for one minute at 500 F. After cooling to room temperature, final weights were recorded and cleaning efficiencies were calculated.

SUBSTRATE MATERIAL: Aluminum Coupons (5052)
CONTAMINANTS: Tuf Draw Vanishing Film 2889 (CAS #: 64741-65-7); Lubricant Mix [Hydroil AW-3 9petroleum hydrocarbon), Express Gear Lubricant F]; Tower Oil & Technology Company LS-H-213 (CAS #: 8052-41-3)

Trial Results:

The Ultra Blue 100 cleaning solution was effective in removing the two drawing compounds, yet it could not clean the lubricant mix very well. Table 2 lists the calculated cleaning efficiencies for the three contaminants.

Coupon 1 100.06 74.77 100.11
Coupon 2 100.1 73.37 100.09
Coupon 3 100 72.9 100.04
Average 100.05 73.68 100.08

Success Rating:

A follow up test, usually based on company input.
