To evaluate successful cleaners on the third supplied oil using immersion cleaning.
Five successful products from the first two oil removal trials were evaluated on the third oil. The products were diluted to 5% in 600 ml beakers using DI water and heated to 130 F on a hot plate.
Fifteen pre-weighed coupons were coated with US Oil Company US Blanking Oil 250 using a hand held swab. Coupons were weighed a second time to determine the amount of oil added. Three coupons were cleaned in each solution for five minutes using minimal stir bar agitation. Coupons were rinsed for 15 seconds in a tap water bath at 120 F and dried using a Master Appliance Heat gun at 500 F for 30 seconds. Once dry coupons were weighed a final time and product efficiencies were calculated.
All five products removed over 85% of the blanking oil from the cold rolled steel coupons. Three of the five removed over 95%. The follow table lists the amount of oil added, the amount remaining and the efficiency for each coupon cleaned.
|Cleaner||Initial wt||Final wt||% Removed|
|Surface Cleanse 930||0.3495||0.0360||89.70|
|Sea Wash Blue||0.4008||0.0042||98.95|
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
All five products will be used on the fourth supplied oil.
