Introduction to Defoamer for Pulp
Defoamers for pulp are essential chemical additives in the pulp and paper industry. During the pulp - making process, a large amount of foam is generated due to the presence of various surfactants, air entrainment, and mechanical agitation. Excessive foam can cause many problems, such as reducing the efficiency of pulp washing, screening, and papermaking operations. It may also lead to uneven paper formation, holes in the paper, and reduced product quality. Defoamers work by breaking down the foam structure, reducing the surface tension of the liquid - gas interface, and preventing the formation of new foam. They can be classified into different types, including silicone - based defoamers, oil - based defoamers, and powder - based defoamers, each with its own characteristics and application scenarios.
