3.3. Calibration.
1. Start-up the equipment.
2. Close the Mixer air stopcock (14) , close the Resin pump air stopcock (3) and
close the Catalyser pump air stopcock (9) .
3. Prepare 2 calibrated test tubes. For maximum accuracy, place each test tube on
scales and weigh. If no scales are available, use the test tubes to calibrate by
volume.
4. Remove the TRIMIX® mixer head (17) with the catalyser head tube (16) .
5. Open the Mixer air stopcock (14) , open the Resin pump air stopcock (3) and
open the Catalyser pump air stopcock (9) .
6. Open the resin valve (5) .
7. Regulate the resin pressure to 1 bar with the resin pump air control (4) and the
user adjusts the resin or component A output for the application on a bad
coating surface and counting the lack of catalyst output to be considered
depending on the mix percentage (If f. e. the product mix percentage is two parts
A for one part B and it is only applied resin in this set-up, the user has to consider
that 33% less product is outputted. Afterwards it will be incorporated while
adding the catalyst when the calibration process has been completed. The
regulation is done by opening the material needle regulator (23) until
adjusting the desired product output. This can also be adjusted by changing the
flow of the available needles 0.8 – 1.0 – 1.3 – 1.5 – 1.8 – 2.0 and as well by
increasing or decreasing the pressure with the resin pump air control (4). Our
recommendation is to start with 1 bar and adjust by opening the material
needle regulator (23) up to a maximum of three rotations. Having reached
three opening rotations at 1 bar without having obtained the required flow, the
material pressure has to be increased in steps of 0.2 bar. Once you have reached
2 bar and go further on without getting the required flow, the needle valve has
to be replaced immediately by the superior one and the calibration process has
to be repeated starting again at 1 bar. When the final user has achieved the
desired quantity of the component A it has to be started the final calibration of
the catalyst or component B.
8. For that open the catalyser valve (12) and adjust the catalyst output pressure
with the catalyser pump air control (10) starting for the first calibration like in
the beginning with the resin at 1 bar.
9. Position the gun tip (19) in the resin measuring cylinder and position the
dismantled TRIMIX® mixer head (17) in the catalyst measuring cylinder. Close
the spray pressure inlet with the air inlet spray pressure regulator (22).
