Defoamer FAG470 is a highly efficient emulsion defoamer based on polyether-modified polysiloxane technology. With its rapid foam breaking, long-lasting foam suppression, high temperature and strong alkali resistance, and excellent dispersibility, it plays a key role in multiple industrial fields. The following application information is derived from the official product data of Hai'an Guoli Chemical Co., Ltd.
This product is a non-ionic formulation with broad chemical compatibility, making it less likely to cause adverse reactions with other additives in complex systems, especially suitable for working conditions with complex formula processes.
| Industry Field | Specific Process/Step | Core Function |
|---|---|---|
| Water Treatment | Aeration tank, sedimentation tank, thickening tank | Eliminate biological foam and surfactant foam to ensure effluent water quality |
| Coatings and Ink Manufacturing | High-speed dispersion, grinding, filling | Suppress micro-foam and large bubbles to prevent pinholes and shrinkage defects in the coating film |
| Textile Printing and Dyeing Processing | Desizing, scouring, bleaching, dyeing, printing | Eliminate foam caused by auxiliaries and mechanical shearing to avoid leveling issues |
| Industrial Cleaning | High-pressure spraying, ultrasonic cleaning, CIP inline cleaning | Control foam height to ensure cleaning fluid circulation efficiency |
| Metalworking Fluids | Cutting fluid, grinding fluid, hydraulic fluid circulation systems | Maintain lubricating and cooling performance, prevent liquid tank overflow |
| Petrochemical Processes | Oil-gas separation, amine desulfurization, ethylene glycol dehydration, reactor, distillation column | Eliminate organic/aqueous medium foam to improve separation efficiency |
| Pulp and Papermaking | Pulp washing, bleaching, paper machine wet end, coating | Break up lignin and sizing foam to prevent holes and spots on paper surface |
It is recommended to continuously add via a metering pump to the foam-generating area. Stir gently before use. It can be added directly or diluted with water. The specific dosage should be determined through small-scale tests; typical addition at extremely low levels is effective.
