To evaluate laboratory selected products for the removal of the supplied cutting oil and compare to current cleaning solvents.
Eight potential products were identified using the lab's on-line database, www.cleanersolutions.org, based on supplied client information. Two supplied products were included in testing to establish baseline. All ten products were used at full strength in 250 ml beakers at room temperature.
Thirty preweighed coupons were coated with Hangsterfer Laboratories Hard Cut 5418 cutting fluid using a handheld swab. The contaminated coupons were weighed a second time to determine the amount of soil added. Three coupons were immersed into each cleaning solution and manual raised and lowered in the cleaning solution to provide minimal mechanical agitation. After one minute of cleaning, the coupons were removed and dried for 30 seconds using compressed air at room temperature. Following air drying, the coupons were weighed a final time to determine the amount of soil remaining. Efficiency for each coupon was determined and average cleaning results for each product were calculated.
Two of the ten products were very effective in removing over 95% of the cutting fluid using minimal agitation. These two products, Solsafe 245 and DS 104 were both more effective than two supplied Bio Spirits products. Another four products removed over 80%. Two of these, Ionox HC2 and SC Actisolv, were as effective as the Bio Spirits 1000. The table lists the amount of cutting fluid added, the amount remaining and the efficiency for each coupon.
|Cleaner||Initial wt||Final wt||% Removed|
|D Greeze 500 Lo||0.1831||0.0227||87.60|
|Bio Spirits 8020||0.2241||0.0139||93.80|
|Bio Spirits 1000||0.1607||0.0309||80.77|
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
Two selected products outperformed both the supplied cleaning products. An additional two products were as effective as one of the current solvents. Follow up testing will be conducted on some of the supplied parts under similar conditions.
