Importance of Abrasive
The final element of blast cleaning is the abrasive itself.
- The amount of cleaning the abrasive will do in a given length of time.
- The quality of the cleaning
- The cost of performing a given amount of work
This performance is determined by abrasive breakdown characteristics, the abrasive size distribution in the blast machine and the abrasive hardness, in addition to all parameter settings and machine condition.
Remember - It's the operating mix that does the work
Abrasive breakdown rate affects the shape of the abrasive in the operating mix and therefore the maintenance on the blast equipment. Abrasive size distribution is also influenced by the breakdown rate.
The smallest size abrasive possible should be selected for each job, providing the blasting results on the components is satisfactory. The size of the abrasive selected however, is now the factor influencing consumption. Rather it is the size at which the abrasive is removed from the machine.
Abrasive hardness is the third major consideration in arriving at proper product selections.
The harder, tougher and more resistant the abrasive, the more energy it will impart to the cleaning task. When possible, use a low breakdown and high hardness product (characteristics found in Thomas Abrasives) for low maintenance costs and maximum cleaning efficiency.
