application of paper dispersant agent

- Jan 18, 2019-

Quansen papersupport ® 9026 paper dispersant agent has low insolubles, superhigh molecular weight and good effection, is popular with the customers.

Quansen products paper dispersant agent has the highest molecular in China, and won the praise of the majority of customers, due to the production capacity constraints, only limited supply of some customers


l Add operation

1. The product should be gently and evenly distributed in the solution tank to be arranged in 0.05% to 0.1% solution and dissolved for 1-2 hours.Dissolve the stirring speed control in the 40-60 RPM, the water temperature is less than 50 ℃.

2. Between the dissolving tank and the dilution tank, 60 mesh screens shall be installed to remove the undissolved sinker.

3. Dilute the solution according to the quality requirements of the paper, and use the quantitative pump or metering tank to avoid the high shear pump when the pump is delivered to the front box of the paper machine, so as to avoid the large molecules being cut off and affect the use effect.

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 ® solid polymer paper adding amount of dispersant 9026 pharmaceutical are as follows: 0.10 ~ 0.50 kg/ton of paper.The optimum dosage depends on the actual machine trial and optimization operation.

 attention 】

1. When used, it is extremely important to effectively disperse the product in the water, otherwise it will lead to the aggregation of dispersants and the production of "fisheye", and the dissolution time will increase. 

2, use warm water can accelerate the dissolution rate, but the temperature is too high, lead to the thermal degradation of polymer chain, viscosity will be affected, the average water temperature should not exceed 50 ℃.

3. Using stirring can help dissolve, but stirring too violently can break down the long chain of dispersing agent, and it is better to adopt ship type propulsion.

4. The water solution should not be stored for more than 48 hours, otherwise the viscosity will be reduced and the effect will be affected.


1. Serve papersupport ® solid polymer paper dispersants 9026 water-soluble polymer, in case of water or liquids of high skid form is formed after soluble in water.Prevent products and their aqueous solutions from spilling onto the floor.If any, should timely use sand, sawdust adsorption, clean it.

2. The product is powder, the operation room should be careful to prevent dust inhalation or adhesion to the body.Wear masks, gloves and overalls to operate according to specifications.

3. Please refer to the safety data manual (MSDS) provided by the company for detailed safety operation guidance.

4. This product and its aqueous solution are not corrosive to the general materials such as stainless steel, plastic, rubber, glass and glass, etc., for the manufacture of tanks, mixers, gauges and pipelines.


1. increase speed, increase output, even writing.

2. non-stick cylinder, not sticky hair clothes, need not add stripping agent, reduce the cost.

3. improve the strength of the paper, raise the utilization ratio of fines.

4. feel is exquisite, improve paper status.

5. Reduce COD and BOD in waste water from paper machine.

6. Reduce energy consumption and help factories to achieve higher comprehensive economic and social benefits.
