Forming air voids and increasing work efficiency
Our air entrainers create stable and homogeneously
distributed air voids. Their main purpose is to stabilize
the air entrained with the water during mixing.
Depending on the requirements, our portfolio of air
stabilizing additives can optimize the size, content and
distribution of the air voids.
Influencing factors
of air entrainers is not to generate air voids but to stabilize
the mechanically entrained air during mixing. Therefore,
air void content is dependent on the mixing process and can
vary depending on mixing device, mixing duration, time of
mixing, temperature and the additives used.
Advantages of synthetically produced air entrainers
There are a variety of different air-entraining agents on the
market, consisting of natural active ingredients, synthetic
surfactants and mixtures. Our synthetically produced
air entrainers do not suffer from quality fluctuations
associated with natural active ingredients. They offer
consistent quality, are more stable and therefore more
reliable. Synthetic air entrainers are characterized by the
close correlation between dosage and volume of entrained
air. In contrast, air entrainers based on natural active ingredients,
when used at higher dosage typically increase the
air content in a non linear manner. The increase in efficiency
of synthetic air entrainers ensure optimized construction
costs and resource efficiency.
Improved workability – higher work efficiency
The everyday example of whipped cream shows: Only the correct quantity of
added air ensures a creamy and stable consistency of mixtures.
Air entrainers from the SITREN AirVoid® range
provide significantly improved workability combined
with increased durability and enable efficient lightweight
construction. For example, our air-stabilizing
additives enable the creation of mineral systems
with an air void content of between 20 and 30%,
considerably improving the thermal insulating
properties.
