To evaluate selected products on second supplied cutting fluid using simulated cleaning process.
Preweighed coupons were coated with the supplied cutting fluid (WA wood, 57 F Cutting oil) using a handheld swab and weighed a second time to determine the amount of soil added.
The same six cleaners were put in a bowl and three coupons were dunked into the solution at a constant rate for 30 seconds of cleaning. The coupons were then put on a tray and when done and allowed to air dry. There was no rinse. The process was done to as closely replicate the process used on site as possible. Once dry, final weights were recorded, and efficiency calculated for each coupon cleaned.
Only one product was moderately successful, removing just over 80% of the cutting fluid. Two products removed over 50% and two removed just under 50%. The table below lists the amount of soil added, the amount remaining and the efficiency for the coupons cleaned.
|Cleaner||Initial wt||Final wt||% Removed|
|Ionox HC 2||0.4813||0.3536||26.530|
|Soy Clear 1500||0.6034||0.2406||60.130|
Success Rating:A follow up test, usually based on company input.
Longer cleaning times should improve the efficiencies for many of the selected products. All six will be evaluated on the third supplied metal working fluid.
