customize the instrument to suit
their needs. Thermo Scientific
HAAKE RheoWin software
automatically recognizes the
pressure cell model to minimize errors
and measures procedures including data
evaluation, and quality control criteria.
In addition, the instrument offers a range
of options designed to increase versatility
and ease of operation:
•Liquid temperature module: de-
signed for precise, uniform tempera-
ture control
•Powerful, electrical temperature
module: for temperatures up to 300
°C
•Additional titanium pressure cell
models: for standard applications
up to 600 bar
• Hastelloy pressure cells: for tests on
chemically aggressive samples up to
175 bar
•Broad rotor portfolio: for testing
low viscosities up to inhomogeneous
samples containing larger particles
• Controlled rate or controlled stress
mode: for enhanced measuring
flexibility from single-point mea-
surement up to a comprehensive
rheological measurement
• Optional oscillation mode: to deter-
mine viscoelastic properties
Union Process Builds
SD100 Attritor Suitable for
Extremely Dense Material
Union Process, known globally as a
manufacturer of particle size reduction
and dispersing equipment, as well as a
supplier of grinding media and material characterization services for a broad
range of research and industrial applications, has custom built an SD100
Attritor for a customer processing a very
dense material.
Because the customer is discharging
the material into two different 55-gal-
lon drums, Union Process was required
to build a heavy-duty riser upon which
the SD100 sits. The mill features a dual
discharge (front and back) so the material
can be discharged into both drums. The
dual discharge configuration allows the
product to exit more quickly, increasing
turnaround time for each batch.
ABB Present Modular
Skidded Resin Production
Unit
Cellier Activity of ABB France has
presented its solution of skidded resin
production unit consisting of interconnected modules which are pre-assem-bled and fully tested before shipment. It
has been designed for an easy transport
in containers, a short installation and
start-up time. The unit is complete and
includes a 12 m3 reactor, raw materials blending tanks, powder and liquids
handling and dosing systems, distillation column and condenser, heating and
cooling systems diluting tanks, pumps,
instrumentation, etc.
A dedicated control system allows the
real time monitoring of the production
and a fine regulation of reaction phases
so as to optimize the batch cycle time and
comply with accuracy and repeatability
required for quality resin. This new solution for the production of resins combines an optimized investment cost and
quick payback.
TQC Announces Availability
of ViscoThinner
TQC, Dutch developer and manufacturer
of paint test equipment, has just finished
the production of the first series of the
ViscoThinner. A benchtop instrument
that measures material viscosity during
the addition of solvents.
The TQC ViscoThinner offers a two
instrument in one option for material
testing. It offers easy continuous monitoring of the material viscosity during
the addition of solvents and thinners to
create supply or RFU viscosity. However
uniquely the instrument also allows definitive viscosity analysis at times pre-select-ed by the user, providing excellent data
relating to shear performance, perfect for
laboratory and factory applications.
The flexibility of the TQC
Visco Thinner allows the user the ultimate
control during the viscosity reduction
process whilst also providing very useful
stability analysis. It is therefore perfectly
suitable for use in both production and
laboratory environments.
The TQC ViscoThinner comes with-
out spindles, but in total three spindles
are available: one plate and two ball
spindles. With these spindles three mea-
suring ranges are covered. The plate
spindle is used to determine viscosity
of fluids of 0-22 poise. The large ball
spindle can be used for measurements
between 0-75 poise, whereas the small
ball spindle is made for measurements
between 0-350 poise.
Conforming to ISO 2884 and BS 3900
A7 besides the spindles a range of verification oil kits are available.
The supplied tin container is filled
with sample fluid and positioned on a
magnetic ring mounted on top the base.
The spindle is submersed in the sample
fluid by lowering the handle. When the
handle has reached the lowest point, the
spindle starts rotating with a set constant
speed. The displays shows the actual mea-
sured viscosity in poise.
The reading of free flowing fluids
will quickly be steady. More struc-
tured materials will need more time
because the spindle applies shear that
influences the reading. That’s why the
TQC Visco Thinner offers several read-
ing presets. The manual reading starts
when the handle is at its lowest point.
The continuous reading gives continu-
ous measurement results. The max hold
function shows the maximum reading,
whereas the time-to-reading function
offers the opportunity to automatically
take readings with a set time interval.
An automatic display hold function is
available to freeze the reading so it can
be noted more easily.
After taking the reading(s) the handle can be lifted to a level where the
spindle is just below the rim of the
sample container. This level offers the
operator the opportunity to spin off
the sample material. When the handle
is raised to its maximum extent the
spindle automatically switches off. The
quick release chuck allows for quick
spindle exchange and eases cleaning the
instrument and spindles.
The TQC ViscoThinner is microprocessor controlled which ensures a
higher accuracy and repeatability. The
accuracy is enhanced by the automatic
multipoint calibration, for which no
dongle is required. CW
