Both the powder detergent and the production process - the SILFOAM® defoamer, provides the
necessary foam control. WACKER offers a variety of foam control systems for three powder
detergent manufacturing processes.
Ready-to-use silicone defoaming powder after the addition of technology
Antifoam powder production in the factory - through powder premixing process
After spray drying, the defoaming powder is sprayed with other heat sensitive ingredients.
Silicone defoamers are also used to degrease the slurry before the spray drying process.
We recommend the use of phosphate as the main component of the powder detergent should be
sprayed. Compared with silicone technology, it has many striking advantages. It is not only
more economical, but also because the additive adheres to the surface of each detergent
particle, so that the defoaming product is always uniformly dispersed in the detergent powder.
In addition, since the mixture having a silicone content of 100% is much lower than the
addition amount of the silicone powder defoamer in the content of 15%, the method is suitable
for more formulations.
Powder premixed production
These silicone defoaming compounds are suitable for the production of defoaming powders or
granules, the so-called plant premixes. They are added as an active substance to the powder
base in a proportion of 5-20%. The antifoam activity increases with the viscosity of the
compound. By heating, viscosity can be reduced and sprayed.
The slurry is degassed
WACKER's silicone defoamers are also used to degass the detergent slurry during spray drying.
The method ensures that the material flow process without beating, no compression, but also
adjust the density of the powder.
