1. Product Description

Defoamer #SY- 4026 is an new organosilicon emulsion type defoamer, developed to resolve the foam problems for pulping procedure. 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 washing level. It is very usefull to save the production and raw materials cost for the pulping mills.

 

2.     Product Features:

* quickly eliminate and suppress foams for long time;

* effectively reduce residual alkali, enhance sizing percentage, and pulp washing level;

* Reduce pulp draining due to foams;

* Nonpoisonous and harmless, easy to degrade.
