Factory Provide Antifoam Paper Making Pulp Oil Use Defoamer
SY-8302 defoamer
Product Description
SY-8302 defoamer is a new organ silicon emulsion type defoamer, developed to resolve the foam problems for pulping procedure, bleaching industry, water treatment industry.The major ingredients are modified polysiloxane, special dispersant and other assistants.
This defoamer, suitable to be used under the conditions of high temperature, has strong ability to quickly eliminate the foams resulted from lignin and other surface active agents. It has many advantages, such as: very stable emulsion, low consumption, not easy to adhere to the machines and mesh, enhancing the work efficiency of the machines, sizing percentage, and pulp washes level. It is very useful to save the production and raw materials cost for the mills.
