AI Overview
Fatty alcohol-based defoamers are high-efficiency, silicone-free agents utilizing long-chain linear or branched alcohols (
) to quickly break surface tension and suppress foam in industrial processes. Known for excellent spreadability, low dosage requirements, and environmental friendliness, they are widely used in pulp and paper manufacturing, wastewater treatment, and chemical processing.
Key Characteristics and Benefits
- Composition: Composed of high-grade fatty alcohols and nonionic surfactants.
- Performance: Provides quick foam knockdown (defoaming) and lasting suppression (antifoaming), particularly in high-temperature or high-shear environments.
- Applications: Ideal for paper machine white water, sizing, industrial wastewater treatment, textile, and coatings.
- Compatibility: Unlike silicone alternatives, they generally do not impact sizing in papermaking.
- Eco-Friendly: Typically non-toxic, odorless, and suitable for biological treatment systems.
Top Industrial Applications
Common Product Types
- Azpc® FA-D01: Known for low COD and excellent dispersibility.
- RK-F0020/RK-F0090: Used for high-temperature and high-efficiency paper mill applications.
- SG-300CD: Suited for high-speed, closed paper machine white water systems.
These defoamers are generally stable, though proper emulsification is necessary for maximum performance, say Teget Kimya and Google Patents.
