Recommendations for problem-free operation
These experience values apply for a wide variety of dual-component materials. Always
follow the manufacturer recommendations for your material in addition to these.
Mixing ratio for very short dosing times
Dual-component media display mostly varying properties (viscosity). They therefore emerge
from the outlet openings with different pressures. This means that deviations in the mixing
ratio can usually be noted at the start of dosing. The choice of the appropriate mixing capsule
(1:1–5:1 / 5:1–10:1) is a crucial factor in the result.
Suck-back with dual-component materials
Suck-back ensures a clean thread break. If it is set too large, already mixed material enters
the dosing pumps, causing them to react with each other. The max. suck-back volume is
saved in the dosing control unit.
Note the pot life
During breaks in work, purge shots prevent the mixed materials from hardening in the mixing
capsule. In the mixing capsule, the mixed materials are completely replaced by the purge
shot. A purge shot interval can be stored in the dosing control unit. The purge shot interval
must be set so it is shorter than the pot life. This measure is not suitable for longer
interruptions to production.
Setting the mixer speed
In order to ensure clean mixing of the two materials, the mixer speed must be set using
the eco-CONTROL EC200 DUOMIX dosing control unit. Speeds of 83 to 800 rpm (± 10 %)
are possible.
