SY-4025 defoamer (antifoam) for pulp

(1)Quickly eliminate and suppress foams for long time;
(2) Nonpoisonous and harmless, easy to degrade
Defoamer #SY- 4025 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 washes level. It is very useful to save the production and raw materials cost for the pulping mills.

Product Features:
(1)Quickly eliminate and suppress foams for long time;
(2) Effectively reduce residual alkali, enhance sizing percentage, and pulp washing level;
(3) Reduce pulp draining due to foams;
(4) Nonpoisonous and harmless, easy to degrade.

4. How to use:
Directly, or after proper dilution
.
This defoamer should be added to black liquor storage and centrifugal screen. Generally it is necessary to use 300g~800g defoamer for one ton of dry paper. The actual amount should be determined according to the tests result.

5. Precautions:
In case freeze took place during transportation and storage, the defoamer should be unfreeze naturally, and stirred evenly before use.
6. Package and Storage
Use 200kgs, 1000kgs packages, or negotiated packages. Sealed and stock under room temperature, away from light. Avoid the defoamer exposed to extremely cold or hot environment. Shelf life is 1 year.

7. Security
Avoid contact with eyes and respiratory system. Once happen, please wash with lots of clear water, to see a doctor is necessary if the situation is serious.
(Remark: the above information for ref, tests would be highly recommended before use the defoamer.)
