Improvement of Blasting Productivity by Optimizing Blasting-Related Operation Parameters

Improvement of Blasting Productivity by Optimizing Blasting-Related Operation Parameters
Available for download

As a means of surface preparation for protective coatings, abrasive blasting provides proper surface roughness and increases the surface area, which are critical in achieving physical and chemical adhesion between steel surface and organic coatings. For application of high-performance coating in a new shipbuilding, the abrasive blasting cleaning is widely favored primarily because of its economic and performance benefits. The abrasive blasting, however, also requires the significant amount of labor hour, whereas its efficiency mainly depends on the blaster’s skill.

For application of high-performance coating in a new shipbuilding, the abrasive blasting cleaning is widely favored primarily because of its economic and performance benefits. The abrasive blasting, however, also requires the significant amount of labor hour, whereas its efficiency mainly depends on the blaster’s skill. Blasting cleaning productivity is known to be affected by a number of parameters, such as air pressure at the nozzle, air volume, abrasive/air mixing ratio, abrasive type and size, and type of nozzle used, and so on. In this study, the effects of these operating parameters are evaluated as a means to find the optimum window for blasting conditions. For this, a series of tests were conducted in the laboratory-scale blasting test facility to simulate the actual blasting practice. The results clearly indicated that the newly optimized blasting condition can improve blasting efficiency and remarkably reduce the amount of abrasive used. And also, a general trend is observed that blasting productivity is gradually increased with grit feeding rate to certain critical value, and then maintained constantly.

The use of passive fire protection (PFP) materials plays an integral role in mitigating fire risk in commercial buildings. Traditional application of these materials has been on-site following the erection of structural steel. Their mechanical durability, exposure to weather and in-flexibility have been a major concern for construction managers and architects.

Statistical Process Control (SPC) has been implemented as a key component of Total Quality Initiatives with great success in every major industry worldwide. SPC is not commonplace in the industrial and commercial coatings application business. This paper introduces the audience to SPC and provides an example of it’s application in industrial coating surface preparation.

State Departments of Transportation let contracts for cleaning and application of protective coatings for steel bridge structures, but often lack staff with the training and knowledge to properly address technical issues that may arise on the project. The department’s engineering and inspection staff may be very skilled at administering a wide variety of construction contracts but lack the experience necessary to deal with the unique issues that often arise on painting projects.
