Defoamer King FAG470, with its unique polyether-modified polysiloxane molecular structure, achieves both rapid bubble breaking and long-lasting foam suppression at extremely low addition levels. The product is supplied as a water-based emulsion, and its non-ionic nature allows it to disperse instantly in water. It also has good chemical compatibility with various system additives, making it less prone to side reactions or system cloudiness. Particularly outstanding is its ability to maintain chemical structural stability under harsh conditions such as high temperatures and strong alkalis, resisting demulsification or failure, making it an ideal choice for tackling complex industrial foam problems.
In terms of application, the "broad-spectrum adaptability" of Defoamer King FAG470 spans multiple industrial fields. Whether it is the elimination of biological foam in municipal wastewater treatment systems, the suppression of micro-foam and macro-foam during the high-speed dispersion of coatings, the defoaming task in high-temperature alkaline baths in textiles, or the foam control in high-temperature and high-pressure processes in petrochemicals — this product provides stable and reliable solutions, effectively improving production efficiency, preventing spillage losses, and ensuring final product quality.
| Industry | Specific Application Process/Stage | Core Function |
|---|---|---|
| Water Treatment | Aeration tanks, sedimentation tanks, thickening tanks | Rapidly break biological foam and surfactant foam, ensuring process stability and effluent water quality |
| Coatings and Ink Manufacturing | High-speed dispersion, grinding, filling and other processes | Suppress micro-foam and macro-foam, prevent defects such as pinholes and shrinkage cavities in coatings, improve product appearance and adhesion |
| Textile Printing and Dyeing Processing | Desizing, scouring, bleaching, dyeing, and printing in hot and wet processes | Eliminate large amounts of foam generated by additives and mechanical shear, avoid fabric leveling issues and operational failures; high-temperature and strong alkali resistance make it especially suitable for high-temperature alkaline baths |
| Industrial Cleaning | High-pressure spraying, ultrasonic cleaning, CIP inline cleaning systems | Control foam height, ensure cleaning fluid circulation efficiency and equipment operation safety, without affecting cleaning power |
| Metalworking Fluids | Cutting fluids, grinding fluids, hydraulic fluid circulation systems | Control foam caused by high-pressure spraying and recirculation stirring, maintain lubrication and cooling performance, prevent fluid tank overflow |
| Petrochemical Processes | Oil-gas separation, amine desulfurization, ethylene glycol dehydration, reactors, distillation towers | Eliminate foam in organic and aqueous media, improve separation efficiency and product purity |
| Pulp and Paper | Pulp washing, bleaching, paper machine wet end, and coating processes | Break foam generated by lignin, sizing agents, and wet strength resins, prevent quality defects such as holes and spots on paper surfaces |
Before use, stir the product slightly to ensure uniformity. It can be added directly or diluted with several times its volume of water before being added to the foaming system. It is recommended to add continuously using a metering pump to the foam generation area (e.g., inlet of aeration tank, above high-speed dispersion tank) to achieve the best defoaming and foam suppression effects. The specific dosage should be determined through small-scale tests based on actual working conditions and foam severity. Generally, a starting addition amount of 0.01% to 0.1% of the total system weight is recommended, followed by gradual optimization.
