The purpose of this trial is to find cleaning chemistries that would be suitable for Metal Wire Manufacturer's needs.
30 coupons of three different substrates (6061 Al, 302 SS and 316 SS) were weighed and then contaminated with the Magnacool CC Oil. The coupons were weighed again, and the oil was allowed to set on the substrate overnight (20 hours). 10 general cleaning chemistries were chosen to be tested. Each cleaning chemistry was used at its minimum recommended concentration (.5% to 5%). For each cleaning solution, one of each substrate was cleaned. Cleaning was done at 120 F for five minutes in a beaker of cleaning solution without any agitation. The coupons were then rinsed for 30 seconds in a tap water bath set at 110 F. After rinsing the coupons were run under air knives for one minute and further dried in a convection oven for 15 minutes at 140 F. The coupons then cooled down for one hour and were weighed to get a percent removal. The coupons were examined under a black light to notice any fluorescing of oil.
SUBSTRATE MATERIAL: #1- 6061 Aluminum Coupons, #2- 302 Stainless Steel Coupons, #3- 316 Stainless Steel Coupons
CONTAMINANTS: Magnacool CC CONTAMINATING PROCESS USED: Oil applied on with swab and allowed to set for 20 hours
Trial Results:
Even though minimal cleaning conditions were used, most cleaners performed well. The Magnacool CC is a relatively easy fluid to remove.
