High-efficiency Papermaking Dispersant Agent
Quansen papersupport ® 9026 paper dispersant agent has low insolubles, superhigh molecular weight and good effection, is popular with the customers.
In the process of paper forming, paper fibers and fillers in pulp are hydrophobic and tend to be flocculated into clumps.It is necessary to add a kind of assistant to increase the viscosity of paper pulp, to facilitate the uniform dispersing of fiber and filler, to make the paper form uniformly smooth and flexible without holes, to make the paper performance stable, not easy to cut paper and powder, and at the same time to improve the tensile strength and dry and wet strength of paper and save pulp.These additives are called paper dispersants.
In most people's impression, polyacrylamide is mainly used in the water treatment field. However, with its extensive application in the industry in recent years, there is no small achievement in the paper industry. Both as a dispersant and a retention and filtration agent, polyacrylamide has been widely used as a substitute for other paper additives products.This paper aims to introduce the mechanism of polyacrylamide as a dispersant for paper making.
Polyacrylamide is commonly used as a dispersant as its sodium salt.As the carboxyl group contained in the molecular chain has a dispersing effect on negatively charged cellulose fiber, and when the relative molecular weight is about 17 million, it can improve the slurry viscosity, which is conducive to fiber suspension. Therefore, this product is a high-efficient dispersing agent of long fiber.
Its molecular structure is as follows:
Its dispersion principle by polyacrylamide molecular chain containing carboxyl, have the function of the lower surface and, help water wetting of solid, packing and so on in the water for the fiber dispersion special advantage, when PAM to join slurry, can make the molecular structure of fiber and filler surface double, outer dispersant extremely strong affinity with water and increase the fiber, filler and other solid wetting by water molecules.The solid particles such as fiber and filler are far away from each other due to the electrostatic repulsion and achieve good dispersion effect.
QUANSEN PAPER DISPERSANT AGENT
【 application 】
Quansen paper dispersant agent has superhigh molecular weight anion polyacrylamide is a water-soluble organic polymer, which can dissolve in water and form a high viscosity liquid. It can promote good dispersion of paper fibers and excellent paper forming effect at a low dosage, improve the evenness of paper pulp and softness of paper, and increase the strength of paper.In paper coating application, paper dispersing agent has high dispersing efficiency, stable paint viscosity, less foam, non-toxic, non-corrosive, can improve the solid content of the paint, and good fluidity and scrubbing resistance, can maintain the gloss of paper, not easy to mold.Paper dispersant can also improve the speed of copying, save time of beating, reduce energy consumption and have significant economic benefits.
Quansen product has a molecular weight of more than 17 million, the solubility of the product is generally less than 1 hour, and the product solution has good filtration performance, which is used for various toilet paper, napkin paper, white towel paper, also widely used for culture paper, there are light-thin paper and newsprint form.

【 specification 】
【 usage 】
● 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.
● 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.
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.
Please contact our technical service manager for technical questions about the application.
【 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.
【 safety 】
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.
