Trial Number 0

Trial Purpose:

To evaluate selected products for lubricant removal

Date Run:

10/09/2002

Experiment Procedure:

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.

Trial Results:

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.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

The four products that removed over 97% will be used in the next phase of testing using ultrasonic energy.
