Trial Purpose:
Abraision Testing of Series 2
Date Run:
09/17/2015Experiment Procedure:
Initial weights of stainless steel coupons were recorded and then coated with 0.5 grams of DCC-17 soil. The coupons air dried overnight and dirty weights were recorded the next day. A clean 5 gallon bucket was filled to the 4 gallon marker 3 times with water from the lotus pro. In a clean 1000ml glass beaker, ozonated water was collected to the 800ml marker. Three dirty coupons were placed on the abrasion machine at a time per abrasion trial. Using a spray nossil, the ozone water was sprayed once on each dirty coupon and then once on a wypal towel. The machine ran for 20 cycles (30 seconds of cleaning), and then the clean coupons were removed to air dry overnight on a tray. This process was repeated for the 30min, 60min, 120min, 240min, and 1440min mark for Series 2 with the same sample of ozone water per trial. Clean weights were recorded for percentage removal the next day.
DCC-17-33% vegetable shortening; 33% lard; 33% vegetable oil; 1% carbon lampblack.
