Trial Report



Trial Number 170

(Client Number 153, Project Number 1)

Trial Purpose: Laboratory evaluations of alternative cleaning products

Date Run: 02/07/02

Experiment Procedure:
Cleaning: Blast coupon with CO2 crystals ~ (-109 F ) at varying flow rates in room temp ~ 68 F. Bursts were 2 seconds each, 3 per coupon in a sweepping motion. Gun was aimed at coupon, perpendicular to surface.

Contaminant: Oil - WD - 40 Company, WD 40 oil/lube petroleum distilate (8052-41-3 50, 68476-85-7, 64742-65-0)

Trial Results


Success Rating
Lab evaluation based on vendor data.

Conclusion
None of the flow rate, delivery combinations with the CO2 snow gun were effective. An increase in effectivness was an increase in flow rate of the CO2 with both the crystal producing nozzles and the flake producing adapter and tube.
