Paper Making Additives

Polyacrylamide PA 350

Model : PA 350

Description锛?lt;/strong>

Polyacrylamide PA 350 is a polyacrylamide-based polyelectrolyte, which is used to improve fiber and ash retention in papermaking. Polyacrylamide PA 350 has a synergistic effect in combination with other additives like coagulants and fixation aids.

Shelf Life(5-30??lt;/span>) 2 years

Application锛?lt;/strong>
Polyacrylamide PA 350 are delivered in powder form and must be dissolved in water before use (dissolving equipment needed). Preferably a 0.3 to 0.5% stock solution, which is diluted to about a tenth of its original concentration before dosage to the paper machine. The time needed for dissolving is 30-60 min. Purified water at 20-40??is recommended for make down and dilution.

Polyacrylamide PA 350 is normally added just before the head box. The dosage is commonly 100- 500 g/t paper. To achieve maximum efficiency, dosing is recommended after the pressure screens, where the flocks are submitted to a minimum of shearing force. More accurate dosing levels and best polymer types can be found by lab experiments and trials.
