Trial Purpose:
To evaluate the effectiveness of client selected cleaners.
Date Run:
10/10/2000Experiment Procedure:
All the products were used at full strength in 600 ml beakers. The solutions were heated to 105 F on a hot plate. Preweighed coupons were coated with the listed contaminants and weighed again. Three coupons with one contaminant were submersed into a beaker agitated with a magnetic stir bar. Cleaning lasted for 5 minutes followed by a tap water rinse at 120 F for 30 seconds and finally allowed to dry overnight at room temperature. Final clean weights were measured and cleaning effectiveness was calculated.
SUBSTRATE MATERIAL: The surface materials used are listed in Table 1.
Substrate Code ID#
aluminum AL 202-5086 H-32
stainless st SS 202-17-4 HR-68
CONTAMINANTS: The contaminants tested are listed in Table 2.
Table 2. Contaminants Used
Contaminant Code CAS#
flux, Ersin 5831 RMA FX 67-56-1, 8050-09-7, 67-63-0
lubricant, 423 LU 64742-47-8
oil, Tap Magic cutting OI 112-62-9
grease, ksl-111 GR 64742-57-0, 64742-62-7, 8052-42-4
Trial Results:
Two of the products, SW 1 and SW3, removed over 80% of the oil applied to the coupons. One product, SW3, was successful in removing the grease and lubricant. The coupons with the lubricant showed cleaning in excess of 100%. This increased efficiency could be due to a couple of things, coupon damage (etching) or dirty precleaned coupons. The dirty baseline coupons appears to be the cause of the elevated results. Table 4, 5 and 6 lists the results for each cleaner.
