Paint
delivery systems utilized for the finishing
of a wide variety of manufactured items such
as motor vehicles, household appliances and
the like are becoming increasingly more
sophisticated. A typical industrial paint
delivery system may comprise a central paint
supply having a number of painting stations
communicating therewith. Such systems can
selectably deliver a variety of different
paints to a given painting station and
include complex fluid pathways having a
number of tanks, pumps and conduits. These
paint delivery systems tend to accumulate
deposits in the course of their use, and
such deposits can decrease, and even block,
the flow of paint there through. The
deposits are comprised of pigment, resins
and other components of the paint. In
addition to causing clogging, such deposits
can also contaminate the paint color, and
can break loose and cause surface defects in
the finished, painted product. Accordingly,
it is necessary to periodically clean the
paint delivery system.
Because of
the complexity of such systems, and because
of the necessity of avoiding expensive down
time, it is generally preferable that the
systems be cleaned without disassembly.
Typically, systems are cleaned by passing a
variety of solvents, detergents or other
such materials there through. Prior art
processes usually involve numerous steps and
multiple cleaning compositions; and such
processes frequently do not provide full
removal of deposits, particularly hardened
pigment residues.
Paint Stripping For paint
Hooks:
Continuous
paint line systems, as used in many
industries, typically include an overhead
conveyor from which a plurality of support
hooks or carries are suspended. Parts racks
or hangers are positioned on the support
hooks. The support hooks carry the parts
racks through the paint line enclosures.
Over a period, the hooks become coated with
paint. With electrostatic painting systems,
the paint build up on the carriers
interferes with the electric current flow.
This may result in improper paint adhesion.
The carriers must be removed and cleaned at
regular intervals. The cleaning procedures
may involve cleaning the carriers or hooks
in solvent. Such a manual cleaning process
involves considerable expense, lengthy down
time and is labor intensive.
In an attempt to overcome problems with
manual cleaning of components of the paint
line systems, at least one in-line cleaning
system has been developed.
Presently available cleaning methods suffer
from inherent problems relating to cost,
operability and the like. For example, burn
off furnaces inherently present safety and
combustion product removal problems.
