Wscosity
The
maximum adhesive
flow rate achievable
without exceeding any
operating limits. The maximum
pumping
rate is measured at the
manifold
outlet.
The rate is based on
an adhesive with a
given
viscosity.
The rate
at
which a material can
be melted continuously on a
long-term
basis while maintaining the output
fluid temperature
within a desired
temperature band. Commonly
expressed in units of
grams/minute,
grams/hour,
lb/min or
lb/hr.
The extrusion tip, the
point
at
which
the
adhesive exits the
gun.
The
nozzle controls the adhesive
stream's volume, shape and
direction.
Nozzles may have single
or multiple orifices.
The
pressure
at
which the
pump
and/or
guns
are operated.
See
product
specifications.
The range of temperatures
in which the specific material
or adhesive in
use functions satisfactorily
in
a
particular
application.
A
device that controls
the dispensing of
material.
An
adhesive that'
remains tacky after curing
or setting.
The amount of materiala
pump
can deliver
per
unit of time.
An
adjustable
device for maintaining
pressure
at the
preset
valve.
A temperature-sensing device
that changes
resistance at a
predetermined
rate in response to
changes in temperature.
ln the Nordson context, a
material used to dissolve
hot melt adhesive to
facilitate
system
cleaning.
The
material
or
product
on
which
the
adhesive is applied.
That
part
of a temperature control
system that detects the
temperature
and feeds this information
to the control device.
A synthetic materialwhich
is
solid
at room temperature,
becomes sofi
when
heated, and
returns to solid
form upon cooling.
A
physical
measurement
of resistance to
flow.
