As the professional manufacture, we would like to provide you Shuodi Molecular Weight of Dispersant for Papermaking. And we will offer you the best after-sale service and timely delivery. The implementation of a full range of quality management strategy to ensure product quality, the whole process of quality testing and tracking, do not let go of any small details, so that your choice of reassurance more at ease.

In the process of paper making, the paper fibers and fillers in the pulp are hydrophobic and tend to flocculate and agglomerate. It is often difficult to produce paper with uniform performance and strength meeting the requirements. It is necessary to add an auxiliary agent to increase the viscosity of the pulp to facilitate the uniform dispersion of fibers and fillers, so that the produced paper is even, smooth, flexible and free of holes, so that the paper performance is stable, and it is not easy to break the paper and powder when making paper, at the same time, it can improve the tensile force and dry and wet strength of the paper and save paper pulp. The additive added is called paper dispersant. There are many kinds of paper dispersants. It mainly includes polyacrylamide and starch modification. Moreover, it should be pyrolytic and its viscosity will decrease rapidly with the increase of temperature, so as not to affect the properties of the original fiber in the dried paper. Ultra-high molecular weight anionic polyacrylamide is a water-soluble organic macromolecular polymer, which is easily soluble in water and forms a high-viscosity liquid. It can promote the good dispersion of paper fibers and excellent paper forming effect at low dosage, improve pulp evenness and paper softness, and also increase the strength of paper. In the application of paper-making coating, the paper-making dispersant has high dispersion efficiency, stable paint viscosity, less foam, non-toxic, non corrosive, can improve the solid content of the paint, and has good fluidity and scrub resistance, can maintain the gloss of the paper, and is not easy to become moldy. The paper dispersant can also increase the speed of papermaking, save the beating time and reduce the energy consumption, which has significant economic benefits. The molecular weight of the product is more than 20 million, the solubility of the product is generally less than 1 hour, and the aqueous solution of the product has good filtration performance. It is used for all kinds of toilet paper, napkin, white tissue paper, and also widely used for the production of cultural paper, glossy tissue paper and newsprint

Product Paramenters

Product performance: 1. The use of this product has a unique dispersion effect and can save pulp and improve the paper yield by 5-10%. The retention rate of fine fiber and feed is increased, and the self-water concentration under the net is reduced. It can be used in a wide range of PH value 5-8. 2. This product can retain all the softness of the pulp, without hindering the addition of other paper additives, and the dispersion effect is not affected by other additives. This product can overcome many paper defects and endow paper with unique physical properties. consumption: Domestic toilet paper machine: speed 120-200 m/min, usage 0.8-2.5 kg/t, paperboard: 0.2-1 kg/t, cultural paper: 0.1-1 kg/t, newsprint: 0.2-0.4 kg/t. usage method: Dissolution: use a non-metallic container, use clean water with a water temperature below 25 ℃, slowly and evenly sprinkle the dispersant on the water outlet of the water pipe while draining the water, so that the dispersant can be flushed into the container with the water, and continuously stir for 50-70 minutes, with a linear speed of 1.5-2.5 meters/second, and the dissolved liquid is of high viscosity for use

Packing & Delivery

matters needing attention: 1. During use, 60-mesh filter screen should be added to filter and reuse to prevent impurities and insoluble fine crystals from flowing into the paper machine process. 2. Keep the work site clean. In case of accidental overflow, clean it with sawdust or sand. 3. When using tap water with high hardness to dissolve, some large soda can be added properly. Generally, 5-8 grams per ton of water is used, especially when the amount of dispersant is large, most of them are water quality problems or the water contains iron, so the PH value of water saving should be adjusted. Packaging and storage: The product is packed with PE valve bag or plastic blister 25kg/bag. The product should be stored in a cool and dry place for 24 months
