apply)
A. Graphite

ADsorbent Desiccants
Desiccants in their LIQUID form are called "ADsorbent desiccants". This includes common
sulfuric acid (used in chemical manufacturing), lithium chloride, or polymeric materials, such as
triethylene glycol.
ABsorbent Desiccants
Desiccants in their SOLD form are called "ABsorbent desiccants". Moisture is adsorbed onto
the surface of a granular material, such as silico gel, which is capable of holding large quantities
of moisture.
Boundry Layer
The layer of air immediately adjacent to the steel surface.
Desiccant(s)
Substances that naturally have a high affinity for water. They draw moisture directly from
the surrounding environment.
You are a coating inspector on a project with dehumidification provided by a rotating bed
type dehumidifier. The silica gel has become contaminated. What do you expect to happen
,with the silica gel?
A. It will continue working after heat regeneration
B. It will continue working after washing
C. It must be cleaned with a detergent
D. It can no longer absorb moisture
D. It can no longer absorb moisture
What effect does the rotating bed dehumidifier have on the treated ambient air?
A. It is cooled and humidity is decreased
B. It is heated and the humidity increases
C. It is heated and the humidity decreased
D. It is cooled and the humidity increases
C. It is heated and the humidity decreases
Abrasive
A solid substance that, because of its hardness, toughness, size, shape, consistency, or
other properties, is suitable for grinding, cutting, roughening, polishing, or cleaning a
surface by friction or high-velocity impact.
Ammeter
A device used to measure the electrical current in a circuit.
Blank Test
Test that does not use metallic abrasives and allows the solvent to reduce in volume
before pouring onto the mirror.
Centrifugal Blast Cleaning
An enclosed blast cleaning process that throws abrasive at the surface being cleaned.
Multi-Table Machines
, A series of independent revolving worktables mounted on a rotating platform or "spider"
in centrifugal blast cleaning.
Standards
A term applied to codes, specifications, recommended practices, procedures, classifications,
test methods, and guides that provide interchangeability and compatibility. Standards enhance
quality, safety, and economy; they are published by a standards-developing organization or
group.
Swing Tables
Work tables used in centrifugal blast cleaning that rotate under the blast of one or more abrasive
throwing wheels. The table swings out with the cabinet door when the door opens. It offers a
high degree of wo handling flexibility and can accommodate very large and heavy work pieces
of up to 9,000 kg (10 tons).
Tumbling Mills
Mills generally used to abrasive clean batch loads and parts. The wheel units are usually mot
ed on the roof of the cabinet to blast clean parts as they tumble in the mill.
In a centrifugal blast operation, the degree of cleanliness is determined primarily by
________?
A. Size of the abrasive
B. Speed of travel
C. Grade of steel
D. Size of the hot spot
B. Speed of travel
Which of the following are advantages of portable centrifugal blast cleaning? (Select all
that apply)
A. Can be used for multiple substrates
B. Dust can be collected for disposal
