Daily Quiz (32)


True or false: In an air abrasive blasting operation, if you change from a sand abrasive with a specific gravity of 2 to a garnet abrasive with a specific gravity of 4, you should expect an increase in cleaning rate.


True or false: Air abrasive blast workers are regularly exposed to noise in excess of 120 dBA.


True or false: In air abrasive blasting operations, the same particle size mix of silica sand and coal slag yield the same profile ranges on steel.


True or false: In air abrasive blast systems, the bull hose carries pressurized air and abrasive to the blast nozzle.


True or false: There are both pneumatic and electric remote controls for air abrasive blast systems.


What is a common name for the safety cut-out device at the blast nozzle of an abrasive blast system, which is connected to a pressure-relief valve on the blast pot?


True or false: Scabbling produces a rougher profile on concrete than does air-abrasive blasting with sand.


Among these choices, what is the ideal air pressure at the nozzle for a blaster to achieve optimum productivity from an air abrasive blast system employed to clean and profile carbon steel?


True or false: The speed of abrasive exiting a venture nozzle in an efficient air abrasive blasting system is typically about 200 mph.


True or False: In judging the conformance of abrasive blast cleaning of steel with SSPC standards, such as SSPC-SP 10, the photos in SSPC-VIS 1 depicting levels of cleanliness take precedence over the written descriptions of required levels of cleanliness.


Which of the following methods for measuring surface profile is not described in ASTM D4417, “Standard Test Method for Field Measurement of Surface Profile of Blast Cleaned Steel”?


What is the source of potential inhalation hazards that blasters face in air abrasive blasting operations?


Which of the following SSPC abrasive blast cleaning standards requires the most rigorous degree of cleaning of steel?


In air abrasive blasting, why is it sometimes useful to adjust the angle of attack (angle of the nozzle in relation to the workpiece)?


If SSPC-SP 16, “Brush-Off Blast Cleaning of Coated and Uncoated Galvanized Steel, Stainless Steels, and Non-Ferrous Metals,” is used to prepare architectural aluminum for recoating, what blast pressure should be used?


True or False: Generally speaking, a high-density abrasive will not clean as fast as a less-dense abrasive.


Among the options below, which is the most important in achieving the specified surface profile on steel when you are air abrasive blast cleaning?


What is a typical particle speed for abrasive in an air abrasive blast system that utilizes a venturi nozzle?

A reduction in air abrasive blast nozzle pressure from 100 psi to 80 psi has what effect on the productivity of the blasting operation?


True or false: ISO Sa2.5, describing very thorough abrasive blast cleaning, gives a more comprehensive written description of the end condition of the steel after blasting than SSPC SP 10/NACE No. 2, Near white metal, which requires a similar end condition.


Which of the following factors influences the appearance of steel after blast cleaning?


What is likely to be the result of oil in the compressed air used for abrasive blast cleaning?


How can air abrasive blasting with sponge media create a profile on steel?


If you are using a supplied-air respirator for protection during abrasive blast cleaning, when is it OK to take it off?


Why is it sometimes useful to adjust the angle of attack (angle of the nozzle in relation to the work piece) when conducting air abrasive blasting?


In air abrasive blasting operations, how is a moisture separator or filter used?


What is most likely to help you achieve the specified profile on the steel you are blast cleaning?


True or false: A research study by Roper, Weaver and Brandon indicated that the number of peaks in a steel surface profile created by abrasive blast cleaning affects coating performance.
