Trial Number 0

Trial Purpose:

To evaluate CO2 snow gun equipment for effectiveness in removing resin from plastic pallets or trays

Date Run:

Experiment Procedure:

CO2 was sprayed on the resin drops directly and the resin drops were then scraped off. The CO2 was sprayed at time intervals of 10, 20 and 30 seconds.

Trial Results:

The CO2 sprayed on the drops of resin for 20 seconds worked the best overall and allowed the resin to be scraped off easily.

Success Rating:

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

Conclusion:

CO2 with a snow gun apparatus cold be a viable cleaning method for the resin on the plastic pallets. Chemical cleaners will be tried next.
