PULPSIL® 672 E
PULPSIL® 672 E is a low to medium viscous, highly effective silicone antifoam emulsion, especially for the use in pulp mills.
PULPSIL® 672 E is characterised by:
- very good long-term efficiency
- very good knock-down efficiency
- excellent drainability
- free of organic emulsifiers
In general we recommend stirring 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.
PULPSIL® 672 E can be dosed undiluted, as it is already sufficiently dispersed by its emulsion form.
If the use of PULPSIL® 672 E should be necessary in diluted form, we recommend using dilutions with solutions made of polyacrylates-based thickener-Systems.
PULPSIL® 672 E acts primarily as an antifoam agent and drainage aid and may be added at various stages during the manufacturing process.
PULPSIL® 672 E is mainly applied to pulp - washing and screening processes, but is also effective during bleaching and in waste water treatment.
PULPSIL® 672 E should be applied in process steps, where high defoaming power and strong drainage performance are necessary.
