paper mill used anti foaming agent with specific gravity improving
the runnability and speed
1. It can remove the air of fiber in the process of wet end to
improve the runnability and speed. It can reduce about 80%--90% air
in the papermaking process. Good effect can be achieved at the
temperature of water from 20 to 60°C.
2. Good drainability, because it discharges the air of pulp, it can
reduce 2—3% water of press section and 20% of filter aid.
3. Improve paper quality.
4. Improve the operation quality of pump and sifter.

· Dripping pump can be added into the defoaming liquid, the primary
amount can be 0.08~0.5kg defoaming agent, the final amount can be
0.05~0.3kg defoaming agent.
· Dilute the product, after dilution defoaming agent should be used
within 12 hours.
· defoaming agent dripping point should be determined according to
the specific production condition
1. Adapting to pulp with various pH values, and also to a
temperature as high as up to 80℃;
2. Maintaining long-time effect in continuous white water treatment
3. Making good result on papermaking machines, without affecting on
the sizing process;
4. Improving the operation of the paper machine and the quality of
5. Continuing the defoaming and the degasing without leaving any
side effect on the papermaking.
