To evaluate selected products for lubricant removal
Eight cleaners were selected from the lab's database of effective testing and from clients previous testing based on supplied input. Seven were diluted to 5% and one was diulted to 3% (Citranox) in 600 ml beakers using DI water. Each solution was heated to 130 F on a hot plate. Twenty-four preweighed coupons were coated with Milacron Marketing Company CIMTECH® 310 metal working fluid concentrate (102-71-6, 78-96-6, 26896-20-8) using a hand held swab. Coupons were then reweighed using a Denver Instruments A250 balance to determine the amount of contaminant added. Three coupons were immersed into each solution and cleaned for 5 minutes using stir bar agitation. Coupons were rinsed for 15 seconds in a tap water bath at 120 F and finally dried using a Master Appliance Hot Air gun at 500 F for 30 seconds. After the coupons were dried, final weights were recorded and efficiencies calculated for each cleaning solution.
All eight products removed over 92% of the contaminant from the aluminum coupons after 5 minutes of soaking. Four products removed over 97%. The table below lists the amount of contaminant applied, the amount remaining and the efficiency for each coupon cleaned.
