SUPER-
WATER® HYDRATION
PROCEDURE
FOR TEST
The
concentration never exceed a concentration of 3 parts per
1000.-or 0.3%
SUPER-WATER®
mut be introduced into the water after filtered and then mixed
bat low speeds.
The
hydration should proceed for at least 6 minutes at 20°C.
An
auxiliary pump is required to feed the solution of SUPER-WATER®
to the high pressure pump (intensifier). This auxiliary
pump must be a positive displacement or a diaphragm
unit ant NOT centrifugal.
Use
filters such as those usually integrated in high-pressure
intensifiers.
However
please NOTE the filters must be used before the addition
of the SUPER-WATER®
solution. This is because filters cause "elongational
shearing" of macromolecules leading to a reduction in
molecular weight and a parallel reduction in effectivness.
Most
commonly used concentrations for increasing performance of
waterjet cutting, blasting and cleaning are:
- 3
parts per 1000 (0.3%)
and of abrasivejet cutting are :
- 2 parts per 1000 (0.2%
Mixing
takes place in a buffer tank.
SUPER-WATER®
requires 6 minutes (at 20°C) for hydration after mixing
with the filtered water before it is used in the high pressure
pump or intensifier.
This
is usually achieved by using a small holding tank to mix and
store the SUPER-WATER®
before being used. Tank size depends upon the flow rate of
the high pressure pump.
The
minimum tank size (gallons) would be 2 to 3 times the pump
flow rate in gallons per minute (gpm).
Thus
for a 5 gpm pump, holding tank size should be 10 to 15 gallons.
