Trial Number 0

Trial Purpose:

To Find a better cleaner for the machine screws.

Date Run:

04/15/2016

Experiment Procedure:

Coupons of aluminum, stainless steel and steel were selected and arranged in rows on a tray. The initial weights were taken and recorded. The coupons were soiled with the Reipo resin and weighed. A manual wiping machine is used to clean coupons for 20 cycles /30 seconds was completed for each set of coupons.Final weights of the coupons were recorded.

Trial Results:

All coupons had residue left behind due to the brush movement of the abrasion machine. The Solstice PF-2A, which did the worst, had an average performance of 97.83% removal. For the products, the amount of cleaner applied to the coupons and wipe could not be controlled, due to the low boiling point of the products they were escaping the spray bottles by themselves. Also, due to the low boiling points the coupons treated with Solstice products had to be cleaned promptly after applying the cleaner. There was a very, very small margin between the top two cleaners, FluoSolv NC and Solstice PF. They were 99.05% and 99.03% effective, respectively. All cleaners had above 97% efficiencies.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.

Conclusion:

All cleaners had above 97% efficiencies. Even the lowest average percent removal by Solstice PF-2A was found to be 97.83%. The best two products were FluoSolv NC and Solstice PF which had 99.05% and 99.03% removal. The Reipo was very easily removed, but due to the brush used with the abrasion machine there were streaks left behind on most coupons. Also, there was no way of controlling how much Honeywell product was applied to the wipe and coupons as the Honeywell chemistries have very low boiling point and began to uncontrollably escape the spray bottles during applications.
