how to improve the effect of the retention and drainage of paper pulp

- Jan 18, 2019-

After years of research, Quansen has produced high quality retention and drainage aids, through multivariate polymerization, which can significantly improve the retention effect of paper pulp, and the drainage speed is significantly accelerated, which is 10% higher than that of ordinary products.



Quansen can provide a wide range of high molecular polymer products. It has broad applicability for fiber and filler. It can improve retention rate of mesh fiberfiller and accessories, save fiber and various additives, increase ash content in paper, improve dewatering efficiency in wire and press section, save steam, improve machine speed, reduce pulp concentration, which helps to maintain good paper evenness, reduce deposits formed in paper machine system due to small components and colloids. Optimize and stabilize overall process operation in wet end. Reduce COD and BOD discharging, bring more economic benefits for customers.

l Add operation

Papersupport ® 2600 series product requirements first mixture 0.3% concentration of curing solution with water.The preparation of curing solution was made by using automatic/semi-automatic barrel tank type polymer foam dispenser.The mixing type of the dissolution tank requires a soft mode to avoid the influence of the shear force of the polymer chain.Water temperature kept at 15 to 30 is advisable.The curing time is 60 minutes.

The curing solution should not be stored for more than 8 hours. It is recommended to be used with the solution.Before adding the slurry, the curing solution needs to be further diluted to 0.01~0.1%.The dilution operation can be performed online using a static mixer.

l Add site

Adding polymer retention agent point should be close to the cages, but in order to ensure that agents mixed with pulp have plenty of time, to avoid excessive floccules, select add commonly before the pressure screen.Individual paper machines can also be added to the pressure screen due to process conditions.When the agent solution is added to the pulp, it should be uniform, fast and fully dispersed into the slurry.For large pipe diameter slurry conveying pipe, it is recommended to use four points of circular tube.

l Dosage

For the vast majority of pulp and process conditions and the papersupport ® 2600 series reagent adding quantity as follows: 0.10 ~ 0.50 kg/ton of paper.The optimum dosage depends on the actual machine trial and optimization operation.

Please contact our technical service manager for technical questions about the application.
