Note
Some material manufacturers may only give a volumetric ratio rather than
weight. In this case if setting the ratio by weight measurement is preferred,
you will need the specific gravity of each material to convert the weight to
volume in cubic centimeters (cc’s).
Example The poly resin (material A) weight is 500 grams and has a specific gravity of
1.09. Divide the sample weight by the specific gravity to obtain the volume
(500/1.09 = 458.71 cc’s).
7. To adjust the ratio, loosen the cap screw to adjust the pump stroke length on the hardener
fluid section shorter, lower slave arm.
8. Tighten the cap screw and check the ratio again.
9. Make notes of each setting until the desired ratio is set.
Note
It is best practice to make notes of all settings during ratio checks including
pump speed settings, pressures, and temperatures. At the start of each work
week, perform another ratio check. This is especially important when using
fillers mixed into the resin to assure filler settling has not occurred in the resin
filter or pump.
10. Flush the ratio block by pushing the flush valves and selecting between solvent and purge on
the 3-way valve on the gun hose.
11. Install the mix housing, springs,
and ball checks on the gun block.
Note
Sometimes it is easier to
install the mix housing
first, then remove the
plugs on the front of the
mix block to install the
ball and springs.
12. Attach the static mixer to the mix
chamber.
13. Turn the Mode Selector switch to
GUN
and dispense material into
a waste bucket.
14. Make note of the fluid pressures for both materials, then turn the Mode Selector switch back
to
RECIRC
and flush the dispense gun and mixer.
Note
The fluid pressures for the two materials do not have to match, but it is
preferable not to have a huge difference. 300 psi on the resin (material A) and
150 psi on the hardener (material B) is generally acceptable. In some cases the
pump may run so slowly that it is difficult to read the exact pressure. As long
