Storage:

Room Temperature Storage(10ºC-40ºC),avoid direct sun light,shelf  life is 6 months. Freeze while 0ºC, dissolve and stir it while used

Package:200KG/1000KG/DRUM

Antifoam Mechanism:

1. The spread of the antifoaming agent replaces

the foaming molecules on the upperlayer of the foam

bimolecular membrane, foaming a film with very low strength;
2. In the process of spreading, part of the solution of the adjacent surface layer will be taken away, reduce the stability of the foam and make it easy to destroy.
Antifoam for papermaking white water wet end

Paper making process is an important process for paper forming. A lot of additives, such as sizing agent, retention agent, filter aid,wet strength agent,dry strength agent etc are to be used to form paper with certain performance. These additives are added in different dosing points. And it's easy to form foaming during white water circulation in closed system.

Paper machine defoamer is usually added in the points with a lot foam, for instance, underwire white water chest or white water tank. Defoamer will be added continuously in several dosing points to give full play of defoamer performance.It will not only achieve good performance but also save cost.
