Agro-Harvest®
AT-530C/520C.
Series of Paper Degassing Defoamer
AT-530C/520C series are specially designed for defoaming of white water in the papermaking industry. It has strong defoaming and foam inhibiting effects on white water, eliminates the influence of air bubbles on the process, avoids the formation of holes and reduces paper breaks. This series also has strong defoaming and foam inhibition effect on resin compounds, polymer compounds, etc. It is suitable for aqueous solution of polyvinyl alcohol, emulsions of styrene-acrylic, pure acrylic and rosin glue sizing agent and other additives.

Composition
Special polymer organic compounds, small amounts of modified polysiloxanes, other excipients.
Applications
- Defoaming of white water in the papermaking industry;
- Defoaming in the production of rosin gum sizing agents;
- Defoaming and foam inhibition in the production and use of emulsion paints and latexes, such as aqueous solutions of polyvinyl alcohol, styrene-acrylic and pure acrylic emulsions;
- Other occasions where organic-silicon defoamers cannot be used.
Usage
This series can be injected directly into the foaming system, or can be diluted and used. When it is added into the foaming system as a foam inhibitor in advance, pay attention to the compatibility with the system. It is recommended to add the defoamer into the white water pool under the net by metering pump, and the usual dosage is about 100–300 g per ton of finished paper. The most economical dosage may be determined after the process test.
Packages
