This new generation high-carbon alcohol product is specifically designed for foam control in paper-making white water processes. It delivers excellent degassing effects for high-temperature white water above 45°C and effectively eliminates apparent foam. The product offers wide white water adaptability suitable for different paper types and manufacturing processes under varying temperature conditions.
Application Guidelines
Application Fields
- Foam control in paper-making wet end white water
- Starch gelatinization processes
- Industries where organic silicone defoamer cannot be used
Application Method
Continuous addition: Equip a flow pump at relevant positions where defoamer is needed, and continuously add defoamer to the system at specified flow rates.
Product Characteristics
- Excellent degassing effect on fiber surfaces
- Superior degassing performance under high, medium, and normal temperature conditions
- Wide range of applications
- Excellent compatibility in acid-base systems
- Superior dispersing performance adaptable to various addition methods
Packaging and Storage
Packaging: Available in 25kg, 120kg, 200kg plastic drums and ton boxes.
Storage: Store at room temperature away from heat sources and direct sunlight. Do not add acids, alkalis, salts, or other substances. Keep container tightly closed when not in use to prevent bacterial contamination. Shelf life: 6 months. If layering occurs after prolonged storage, stir evenly before use without affecting performance.
Transportation: Ensure proper sealing during transport to prevent moisture, strong alkalis, strong acids, rainwater, and other contaminants.
