Antifoam for pulp process:
Anionic surfactants are formed by chemical reaction between alkali and wood or Straw grass during cooking process.
Silicone defoamer or non-silicone defoamer are usually used for pulp preparation.Silicone and non-silicone defoamer has it's own focus according to different raw materials.Silicone defoamer series are more efficient in pulp washing with hard wood and soft wood as raw materials. Silicone based defoamer series are usually continuously added to the filtered black liquor during pulp washing process.
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.
Foam Control Agents For Water treatment:
In water and wastewater treatment industries, the fluids contain bacteria, chemicals, and other compounds hazardous to human health. The causes of foam in different water treatment plants are varied. Foam can be caused by biological activity, mechanical action, chemical contamination, surfactants or some polymer. Regardless of the cause, excessive foams are unacceptable and often interfere with operations.
