The National Shipbuilding Research Program Users Guide To Selection Of Blasting Abrasives Final Report

The purpose of this guide for abrasive selection is: through proper abrasive selection shipyards can improve productivity, reduce waste, and decrease the costs associated with abrasive blast cleaning. Abrasive blasting is generally acknowledged to be the most effective and efficient means of surface preparation. Blasting accounts for about two-thirds of the cost of the surface preparation and coating operation, which is itself, a major cost component of shipyards. The wide variations in types of abrasive, blasting processes and operator proficiency, result in huge fluctuations in the efficiency and cost of the abrasive blasting operation. Therefore, significant reduction in cost and improvement in production can be attained by proper selection and use of abrasives, meeting the objective of this project; to develop a shipyards guide to select abrasive and blasting parameters that will optimize this activity.

The first comprehensive monograph in blast cleaning technology, this book provides a comprehensive review of the technology, with an emphasis on practical applications. The author first systematically and critically reviews the theory behind the technology. Next you’ll learn about the state of current blast cleaning, surface quality aspects, and the effects of blast cleaning on the performance of applied coatings. You’ll also discover many of today’s cutting-edge applications, including micro-machining, polishing, maintenance, and surface preparation for coating applications. Finally, the author describes recent advanced applications in the machining industry, including blast cleaning-assisted laser milling.

"This synthesis will be of interest to state DOT bridge maintenance and construction engineers; regulators, consultants, and contractors involved with the removal of lead paint from bridges and structures; and structural coatings specialists, chemists, and researchers. This synthesis describes the current state of the practice for the removal of lead-based paint from existing highway steel bridges."--Avant-propos.
