Overview, selection and product introduction
A large amount of foam often appears in the paper machine system. This is because there are many pumps rotating at high speed and the liquid level is turbulent in the paper machine process, resulting in poor dehydration of the wire, paper breaks, and increased holes. In order to further improve production efficiency, increase production capacity, dehydrate the wire, and reduce paper breaks, defoaming agent is a good choice.
Defoaming agent is a kind of agent that can reduce the foam generated in the pulp and white water of paper machine, which helps to improve the dehydration of the wire, reduce the cavitation of the pump and the hole in the paper, and effectively reduce the production cost.Our alcohol defoaming agent is very easy to dehydrate, which can effectively reduce the foam generated in the white water of the paper machine, help to improve the water filtration performance of the wire, reduce the cavitation of the pump and the hole in the paper, and effectively improve the quality of the paper machine, effectively reducing the production cost.
Papermaking wet end defoamer PM-8136
Chemical composition
mixed emulsion of higher fatty alcohol derivatives

On-site defoamer monitoring and effect evaluation
Use EGT-air content meter to test paper machine white water
Observe the surface foam of the paper machine white water tray and the white water bucket outside the machine
Observe the water filtration effect of paper machine
Observe the vacuum reading of the wet end suction box
The number of paper bubbles (pinholes and spots)
