RJ-P1012TH is a kind of silicone based emulsion defoamer, designed for foam controlling in black liquor, washing production line of pulping industry. Compared to traditional defoamer, it has an excellent resistance to alkali, high temperature and high shearing, It also has a good stability in black liquor system without gel formation. Small amount of addition can play an excellent anti-foaming effect. In addition, the defoamer improves the pulp production efficiency by reducing the air flux and the amount of foam caused by the lock obviously

Recommended Usage

It is recommended that the initial amount of 0.08-0.5kg defoamer should be added per ton of pulp, and the final expected value is adding 0.05-0.3kg defoamer per ton of pulp (air-dried).

In order to control the drop amount, we can dilute the product, add water to the defoamer and mix it slowly, the defoamer after dilution should be used as soon as possible, and the general storage period is less than 12 hours.

The drop point of defoamer should be determined according to the specific production conditions, and the best drop point should be improved to the minimum amount of defoamer.


RJ-P1012TH is available in 25kg, 50kgs or 200kg plastic drum or other packing on request.
