The manufacturer of technical grade sodium hexametaphosphate tells you the principle of paper pulp dispersant
When it comes to paper, it is a common item in life. Household paper and work paper are used in a wide range of applications, and the quality requirements for paper are more stringent. Manufacturers of technical grade sodium hexametaphosphate also have a full understanding of the dispersion effect of technical grade sodium hexametaphosphate in papermaking, so that the downstream papermaking industry can produce better quality paper.
For the papermaking process, fibers, fillers, and some additives are all water-insoluble and tend to accumulate in the aqueous solution, and different materials are often kept away as far as possible due to incompatibility. This makes it difficult to obtain paper with uniform properties and ideal strength. Therefore, technical grade sodium hexametaphosphate is added in the paper production process. Technical grade sodium hexametaphosphate is an inorganic dispersant and is easily soluble in water. It can promote a good dispersion of paper fibers and an excellent paper forming effect, and improve the uniformity of pulp And the softness of the paper can also improve the toughness of the paper.
Technical grade hexametaphosphoric acid can be connected to each other and polymerized into a helical long chain, which can be adsorbed on the surface of the particles to enhance the hydrophilicity of the particles, and significantly increase the negative potential of the particle surface, so that the electric double layer is more stable and the dispersion effect is better.
Water quality in paper production also plays an important role. Poor water contains many metal ions such as calcium, magnesium, and iron. The technical grade sodium hexametaphosphate dispersant not only has the function of dispersing but also the function of complexing agent. Because technical grade sodium hexametaphosphate can complex metal ions such as calcium and magnesium in water, it is not easy to form precipitation, so that the color of the paper can meet the needs of users.
As the requirements for paper are higher, the quality of technical grade sodium hexametaphosphate as a dispersant is improved. Chuandong Chemical Group, the manufacturer of technical grade sodium hexametaphosphate using thermal phosphoric acid, is more professional in its production quality.
