Trial Purpose:
To evaluate successful cleaners on supplied parts
Date Run:
10/10/2002Experiment Procedure:
Three products from the previous trial were selected for cleaning supplied parts. Two were diluted to 5% and one was diluted to 3% using DI water in 1500 ml beakers. All three products were heated to 130 F on a hot plate. Each solution was degassed for 5 minutes in a Crest 40 kHz ultrasonic tank. Several supplied parts were cleaned in each solution for 5 minutes using ultrasonic energy. Parts were rinsed in tap water at 120 F for 15 seconds, dried using air blow off at room temperature for 15 seconds, followed by a Master Appliance Heat Gun at 500 F for 30 seconds. Once dry parts were visible inspected and wiped with a white towel to determine cleanliness.
Contaminant: Milacron Marketing Company CIMTECH® 310 metal working fluid concentrate (102-71-6, 78-96-6, 26896-20-8)
Trial Results:
Both Citranox and Daraclean 282 appeared to remove the fine layer of black contamination present on the dirty parts. Upon wiping the surface with a kimwipe soaked with acetone resulted in no visible black on the parts cleaned in Citranox and very little for the Daraclean cleaned products. The wipe test of the Aircraft & Metal Cleaner cleaned parts resulted in the appearance of the black residue.
Success Rating:
A follow up test, usually based on company input.Conclusion:
Citranox worked the best out of the three cleaners, followed closely by Daraclean 282.
