To compare the effectiveness of two products on four soils using immersion cleaning.
Date Run:
01/31/2012
Experiment Procedure:
The two solvent-based products were used at full strength in 400 ml beakers at room temperature. Three preweighed aluminum coupons were coated with each additional soil (Synextreme HD2, Lubriplate High Temp, Antiseize and Mold dry film lubricant). Coupons were weighed a second time to determine the amount of soil added. Three coupons were cleaned in each solution for five minutes using no agitation. At the end of cleaning, the coupons were allowed to air dry at room temperature overnight. Final weights were recorded, and efficiencies were calculated.
Trial Results:
The Solsafe 245 was effective on two of the four additional soils and the Biosolv was not effective on any of the four soils. The Solsafe 245 product showed signs of being able to remove the Antiseize and the Molydry film lube but would require additional modification of the cleaning process to achieve successful removal. The table lists the amount of soil added, the amount remaining and the affiance of each coupon cleaned.
