To identify a cleaner to remove C-Eblis cutting oil from steel parts
Eight cleaners were selected based on vendor information and from the lab's database of effective testing trials.
Each solution was diluted to 5% using DI water and heated to 130 F on a hot plate.
Twenty-four preweighed steel coupons were coated with C-Eblis Cutting Oil (64742-53-6, 64742-52-5) using a hand held swab. Coupons were weighed again.
Three coupons were immersed in each solution and cleaned for 5 minutes using stir-bar agitation. Following cleaning, the coupons were rinsed in tap water at 120 F for 30 seconds and dried using a Master Appliance Heat Gun,model HG-301A, at 500 F for one minute.
Once coupons were dry, a final weight was recorded and efficiency was calculated.
Two of the products removed just over 80% of the oil from the coupons using stir bar agitation. The other cleaners removed between 70 and 75%. The following table lists the individual effectiveness for each coupon.
|Cleaner||Coupon 1||Coupon 2||Coupon 3||Average||Std Dev|
After removing the agitation from the cleaning solutions, the oil migrated out of the solution to the top where it could be easily removed.
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
Daraclean 283 and Inproclean 3800 were moderately successful in removing the C-Eblis cutting oil from the steel coupons. With the addition of a more aggressive agitation method (ultrasonics) the cleaners should be more effective in cleaning the oil.
Green Stuff and Beyond 2001 will also be evaluated in the next test.
