What Kinds Of Applications Are Not So Effective For CO2 Pellet Blast?
A. The effectiveness of CO2 Pellet Blast may be limited by some of these factors. Base materials and contaminates are multivaried. Hardness viscosity, grain, toughness and other such measures combine to make a wide range of cleaning situations. Every substrate has a threshold for absorbing energy (Et). If the kinetic energy of the pellets exceeds that threshold, damage will occur. Also, every containment or coating exhibits a minimum kinetic energy required to shatter, splinter or be penetrated (Ep). In similar fashion, the adhesive bond between the coating and the base material will not fail or be released until a certain minimum shearing force is applied (Es). CO2 Pellet Blast is effective in almost any application where Et is clearly higher than either Ep or Es. This is the “window of effective cleaning”. Wood and some softer plastics could be damaged. Brittle substances like thin untempered glass, could shatter. Some coatings are very hard and some bond very tenaciously. In these
