Trial Number 0

Trial Purpose:

To evaluate client products for grease, cutting oil and quench oil cleaning

Date Run:

09/03/2002

Experiment Procedure:

Based on client request four products were selected to clean three contaminants:
Oil - Citgo Quenching Oil 22 (64741-89-5, 8052-42-4)
Oil - Citgo Kutwell 40 (64742-52-5, 64742-53-6)
Grease - Formax Manufacturing Corp F-26 grease stick polishing lubricant (68815-16-7, 67701-27-3, 64742-52-5, 102-71-6). Thirty-six preweighed coupons were coated with each contaminant in sets of three using a hand held swab. A second weighing was performed to determine the amount of contaminant added.
Each product was poured into three 600 ml beakers. Coupons were immersed into a beaker and cleaned for 5 minutes using stir-bar agitation. Coupons were then rinsed in a tap water bath at room temperature for 15 seconds and dried using a Master Appliance Heat Gun at 500 F for 1 minute. After coupons were dry final weights were made and efficiencies were calculated.

Trial Results:

All four cleaners were successful in removing over 90% of the cutting fluid.  All cleaners except Vertec BioGold removed over 99% of the quench oil.  Only Citrikleen was successful in removing over 85% of the grease during the 5 minute cleaning.  The table below lists the average efficiencies for the four cleaners.

The Vertec Bio Gold encountered difficulties in the rinsing stage.  It was the only product to have substantial residue after the 15 second rinsing at room temperature.  An increase in temperature or perhaps a spray rinse may be more effective in removing the cleaner from the coupon surfaces.

Success Rating:

A follow up test, usually based on company input.

Conclusion:

Improved rinsing protocol may increase the efficiency of the Vertec BioGold
