To find cleaners for oil and abrasive removal
Five products were selected from the lab's database based on previous testing results. A sixth cleaner was selected based on supplied client data. The semi aqueous terpene was used at full strength in a 600 ml beaker. The other five products were diluted to 5% using DI water in 600 ml beakers. All six products were heated to 120 F on a hot plate.
Eighteen preweighed coupons were coated with Speed Fam Industrial Applications Vehicle 210 with Boron Carbide abrasive using a hand held swab. The oil/abrasive mix was forced dry using a Master Appliance Heat Gun at 500 F for 3 minutes. Coupons were allowed to cool to room temperature and weighed a second time. Three coupons were immersed in each solution and cleaned for 5 minutes using stir-bar agitation, rinsed in tap water for 15 seconds at 120 F and dried with the heat gun for 30 seconds at 500 F. Once coupons were cooled to room temperature, final weights were recorded and cleaning efficiencies were calculated.
Five of the six products removed over 85% of the oil/abrasive mix within five minutes of cleaning. Two products, Safety First and Polyspray Jet 790 XS removed over 95%. The table below lists the amount of oil/abrasive applied and removed for each coupon.
Table 1. Oil/Abrasive Removal
|Cleaner||Initial wt||Final wt||% Removed|
|Formula 815 GD||0.1113||0.0159||85.71|
|LPS Precision Clean||0.1441||0.0218||84.87|
|California Parts Washer||0.1711||0.0322||81.18|
|Polyspray Jet 790 XS||0.1195||0.0009||99.25|
Success Rating:Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
The five successful products will be used in the next trial with the aluminum oxide based abrasive. Cleaning times may be increased to improve efficiency.
