Suny SY-4031 Defoamer Emulsion for Paper Pulping
Item No.: SY-4031
Product Description
SUNY SY-4031 is a kind of polyether-based defoamer, made mainly from polyether modified polysiloxane.It it designed to control the foams in the paper pulping process. It is fast to eliminate the foams caused by surfacants and lignin, and performs well in eliminating the foams, and in preventing them.
Key Features and Benefits
- Quick to eliminate and suppress foams for long time;
- High-temperature resistance, strong-alkali resistance
- Reduce the loss caused by foam slurry
- Low organic silicon content

How to use
Directly, or after proper dilution. this defoamer should be added to black liquor storage and centrifugal serene which is the site of foam . The normal dosage is 200-800gram/ton pulp. For the other fields, the actual amount should be determined according to the tests result.
Package and Storage
In case freeze took place during transportation and storage, the defoamer should be unfreezed naturally, and stirred evenly before use.
Use 200kgs, 1000kgs packages, or negotiated packages. Sealed and stock under room temperature, away from light. Avoid the defoamer exposed to extremely cold or hot environment.
Entrained air and surface foam can cause a variety of quality, production and environmental problems for industrial operations. To help industrial operations overcome these issues, SUNY offers a full range of foam control agents and antifoam agents. These foam control products minimize the detrimental effects of entrained air, surface foam and surfactant-stabilized foam in aqueous manufacturing systems and address most, if not all, foam-related issues and regulatory requirements.
Our portfolio of foam control agents and antifoam agents includes oil-based defoamers, silicone-based defoamers, surfactant-based concentrate defoamers, and water-based defoamers as well as a variety of specialty formulations. And, our portfolio comes backed by a dedicated team of applications experts and state-of-the-art monitoring and control solutions to provide complete system control.
