Paper Machine Defoamer and De-Aeration

The high-speed paper machine is very sensitive to foam related issues. The closeness of the water system and the use of wet paper chemicals enhance the foam generating capacity of pulp and paper making system; which as a result, obstructs in providing quality paper and in achieving productivity goals.

Defoamer are used in paper mills to decrease the production of foam while manufacturing paper.

Advanced features: –

  • No foam related issue can be seen on final paper quality
  • Decreases environmental claims
  • Try to improve drainage-aid in paper mill
  • It also reduces the paper breakage

 

Balaji Chem Solutions offer a vast variety of De-foamer which is used in a paper mill like- silicone De-foamer, oil-based De-foamer, and many more. To know more about: Water Based Defoamers

Frequently Asked Questions

Q.1 What is a paper machine defoamer used for?
A paper machine defoamer is used to remove foam and trapped air from the pulp and white water system. It helps improve drainage, sheet formation, machine speed, and overall production efficiency.
Q.2 Why does foam occur in paper machines?
Foam forms due to surfactants, chemicals, dissolved air, recycled fibre, and mechanical agitation. These bubbles affect sheet quality, so a defoamer is essential for smooth operation.
Q.3 What are the benefits of using a defoamer in a paper mill?
It improves drainage, reduces breaks, stabilises vacuum, stops streaks or pinholes, increases machine speed, and lowers chemical wastage.
Q.4 Which defoamer is considered the best for paper machines?
The best defoamer depends on your pulp type, machine speed, pH, and temperature. Mills often prefer silicone-based or oil-based defoamers because they work fast and require low dosing.
Q.5 Can a defoamer increase paper machine speed?
Yes. By removing surface foam and entrapped air, drainage improves, allowing higher machine speed and fewer breaks.
