PULPSIL® 737 E
PULPSIL® 737 E is a low viscous, highly effective silicone antifoam emulsion, especially for the use in pulp mills.
PULPSIL® 737 E is characterised by:
- low viscosity (easily dosable)
- excellent long-term efficiency
- very good knock-down efficiency
In general we recommend to stir the emulsion before use (approx. 3 minutes with a propeller stirrer at 200 - 400 rpm). But be cautious: too high shear can break the emulsion. The emulsion should be added undiluted, as it is already sufficiently dispersed by its emulsion form. If a pre-dilution still should be necessary, we recommend dilutions with cold water in proportions of 3 parts emulsion : 1 part of water to max. 1 part emulsion : 1 part of water. Sufficient quality of this predilution should be checked by previous trials in laboratory scale. For manufacture of the pre-dilution add first the emulsion and then add the water under weak stirring. The ready-made dilution has to be agitated 2 to 3 times a day for 15 to 20 min by weak stirring and should be processed within few days.
PULPSIL® 737 E acts primarily as an antifoam agent and drainage aid and may be added at various stages during the manufacturing process for hard- and softwood.
PULPSIL® 737 E is mainly applied to pulp - washing and screening processes, but is also effective during bleaching and in waste water treatment.
The 'Best use before end' date of each batch is shown on the product label.
Storage beyond the date specified on the
label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
