Which one of the following best describes the way most modern efficient spray booths work:
Unfiltered air enters through top and extracted through floor filters/vents
Unfiltered air enters through floor and is extracted through vents
Filtered air enters through top and extracted through floor filters/vents
Filtered air enters through gaps in doors and extracted through roof
2
Which one of the following would be the most likely cause of the paint being forced out of the top of a spray gun
Air cap blocked causing backward pressure surge
Volume control open to far, causing backward pressure
Fluid needle packing jammed in close position
Fluid tip or nozzle is damaged preventing needle seating
3
The tapered spray gun component that works with the trigger to regulate paint flow is called:
The air cap
The fluid tip
The fluid needle
The air valve
4
Where and how should lubrication be applied to a dual action sander (DA)that does not have sealed bearings
A few drops of recommended oil should be applied into the air inlet
A silicone lubricant should be sprayed on all moving parts
Strip the sander down and apply oil/grease to the bearings
Some copper grease should be pushed into the air inlet
5
A compliant gun-cleaning machine suitable for 2K materials should:
Remove paint residue using a water-based cleaning solution
Recirculate cleaning solvent and extract fumes to atmosphere
Incorporate internal brushes, which clean the outside of the spray gun
Use only cleaning solvent and extract fumes to used solvent container
6
In order to ensure continued efficiency of operation, spray guns should be periodically:
Sent back to suppliers for servicing
Stripped down, cleaned and checked for worn parts
Left in solvent to remove accumulated paint over night
Sent to manufacturers for thorough overhaul
7
Which one of the following best describes the way most modern efficient spray booths work:
Unfiltered air enters through floor and is extracted through vents
Filtered air enters through top and extracted through floor filters/vents
Unfiltered air enters through top and extracted through floor filters/vents
Filtered air enters through gaps in doors and extracted through roof
8
Which one of the following is the most likely cause of paint dripping from the fluid nozzle or tip
Fan width control opened too far
Mismatched fluid needle and nozzle or tip
The paint cup has been overfilled
Atomizing air cap loose or damaged
9
To comply with Health and Safety regulations, how should a spray booth be set up to operate?
At negative air pressure
At positive air pressure
Below atomizing pressure
Above atmospheric pressure
10
If black refuse sacks are used for masking wheels prior to spraying, what are the likely results to be:
They will melt because of the solvents
Paint will penetrate through to the wheels
Dried paint may be blown off in flakes onto the wet paint
They will react with the paint and give off dangerous fumes
11
Moisture could result in a fault known as:
Blistering
Floating
Pinholing
Orange peel
12
Which of the following is considered to be most important when selecting a new compressor
The number of employees working in preparation area
The total number of tools likely to be used at the same time
How much noise it makes in full operation
The number of times the compressor needs checking and servicing
13
Which of the following is an advantage of using a gravity fed spray gun over a suction fed spray gun
A better level of final gloss finish can be achieved
A higher rate of paint vaporization can be achieved
Smaller volumes of paint can be mixed and applied
There is more control of air pressure and fan width
14
What equipment is designed to remove dust whilst sanding vehicle paintwork
Vacuum extraction
Fume extraction
An air duster
Spray booth filters
15
A coagulant additive is used with water-based paint materials to:
Turn surplus paint into a gel which becomes non-hazardous waste
Prevent the paint from solidifying, allowing long term storage
Control the level of the paints hiding power, from translucent to opaque
Improve the adhesion properties when aplied to plastics
