To evaluate residue via coefficient of friction for aerosol dust mop treatment products.
Date Run:
06/02/2009
Experiment Procedure:
Coefficient of friction was measured with an IMASS, Inc SP-102B-3M90 Slip/Peel Tester (Figure 1). Two types of friction coefficients were measured using this instrument. The first, Static CoF, was determined by obtaining the force required to move the specimen from a stationary position. The second, Sliding CoF (or Kinetic), was found by measuring the average force required to maintain movement at a certain rate. Measured forces will have peaks and valleys in the amount of force needed to keep moving. Average these values results and dividing by the weight of the object will result in the desired coefficient. Figure 1. IMASS Slip/Peel Tester
The Slip/Peel tester was first adjusted to ensure that the device was properly calibrated for the sled weight being used. A coupon was then placed and clamped onto the bed of the device. The speed of the bed was set to 45”/min. The instrument records two values, the peak, the valley and calculates the average. The device was run three times per coupon for measuring the Static CoF and three times to measure the Kinetic CoF. Each coupon’s value was averaged and then the values for each finish (three coupon averages) were averaged to get one value for the Static Coefficient of Friction and one value for the Kinetic Coefficient of Friction. The coupons were then sprayed with the supplied cleaning product. The cleaner had a 5 second dwell time on the glass coupons and then was wiped off using a Kmberly-Clark Wypall X60 reinforced wiper. A second set of readings for SCoF were recorded for the treated surface. Following the SCoF a second application of the cleaner was applied to the measuring the KCoF.
These values for treated coupons were compared to the CoF for the same untreated coupons to determine the effect on CoF.
Coefficient of Friction = Ratio of tractive (pulling) force to the normal force (sled weight):
CoF = F/N = (Tractive force)/(Normal Force) = (meter reading)/(sled weight) Sled weight = 1
Trial Results:
The Amrep A00811 product resulted in a decrease for both static and kinetic CoF. The Swiffer product and the Amrep Misty A00810 had the opposite with increases for both. The Spartan and Claire products had mixed results. Spartan's Dust Mop/Cloth treatment had decreases in the static CoF high and low values but had a slight increase in the average value. The kinetic CoF had a decrease in the low value but slight increases in the high and average values. Claire's Dust Up had decreased values for the static CoF measurements and the kinetic CoF low and average values.
