To evaluate selected aqueous based products on first supplied lubricant.
Ten products were selected from the lab's on-line database, www.cleanersolutions.org based on client supplied information and past product performance. The products were diluted to 5% using DI water in 600 ml beakers. The dilutions were heated to 130 F on a hot plate.
Thirty preweighed alloy coupons were coated with the first supplied lubricant and weighed a second time to determine the amount of contaminant added to each coupon. Three coupons were immersed into each solution and cleaned for 5 minutes using stir-bar agitation. Coupons were rinsed in room temperature tap water for 15 seconds and air dried using compressed dry air for 30 seconds. A final weight was recorded and efficiencies were calculated for each coupon cleaned.
Of the ten products selected, only three showed some signs of being able to remove the thick lubricant from the alloy coupons. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
|Cleaner||Initial wt||Final wt||% Removed|
|SC Aircraft & Metal||1.7501||1.1948||31.73|
|Polyspray Jet 790 P||1.9233||1.2543||34.78|
|Ozzy Juice SW 1||1.8810||1.5022||20.14|
|Sea Wash Blue||1.8201||1.4618||19.69|
|Ionox HC 2||2.0175||1.3857||31.32|
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
These three products, Micro 90, Ionox HC 2 and Aquavantage will be tested at higher concentrations in an attempt to improve efficiencies. In addition, non-aqueous products will be selected for evaluation as well.
