Use
WS 7430 is a
synergistic blend of anionic polymeric sequestrants, dispersants and organic
sequestring agents of phosphonate type.
It is recommended for deposit inhibition in industrial water
systems like recirculating cooling systems, cooling towers, waste water streams
facing deposition problems, paper mill applications etc.
Almost mineral scales can be inhibited by WS 7430 like
Calcium Carbonate, Fe and Mn based scales, CaF2 etc.
Features
WS 7430 is a
very concentrated, synergistic blend resulting in low dose rates and normal use
cost.
WS 7430 is suitable for use in waters containing high
solids amounts, like scrubbers and paper mill applications.
Appearance
Clear colourless to yellow
Density (kg/m 3 ) : 1120 -1240
pH : 4
Freezing point : < -4°C
These data are to be seen as typical values and should not be
considered as specifications.
Feeding
For most applications a continuous treatment level of 0.5 -
5.0 ppm of WS 7430 in the make-up water is acceptable. However, optimum
dosage will depend on the nature and severity of fouling and the operational
parameters of the system.
WS 7430 is
an mildly acidic material and therefore corrosion resistant feeding equipment
should be used.
Handling precautions
Wear suitable protective clothing, goggles and gloves.
WS 7430 is a mild skin irritant and moderate eye
irritant.
In case of contact immediately flush with water for 5 - 15
minutes. After eye contact seek medical advice. Do no swallow. Before use review
the Material Safety Data Sheet for additional information.
