To evaluate aqueous alternatives on grinding fluid using ultrasonic energy
Six products from previous trials were selected for testing. Five of the products were diluted to 20% and the sixth product was diluted to 5%. Products were heated to 130 F and immersed in a Branson 40 kHz ultrasonic tank and degassed for at least five minutes.
Eighteen preweighed coupons were coated with the supplied grinding fluid using a handheld swab and weighed a second time to determine the amount of soil added. Three coupons were cleaned with ultrasonic energy for five minutes, rinsed in tap water for 15 seconds at 120 F and dried using compressed air at room temperature for 30 seconds. Final weights were recorded, and efficiencies calculated for each coupon cleaned.
Five of the six products removed more than 90% of the rust preventative. One removed less than 80%. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
|Cleaner||Initial wt||Final wt||% Removed|
|Aquavantage 1400 GD||0.1423||-0.0001||100.07|
|Bio T 300 B||0.1761||0.0195||88.93|
|SC Aircraft & Metal Cleaner||0.1508||0.0078||94.83|
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
The top five products from this trial will be evaluated next on the supplied lubricant.
