The manufacturer of industrial grade sodium hexametaphosphate in China tell 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 industrial grade sodium hexametaphosphate also have a full understanding of the dispersion effect of industrial 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, industrial grade sodium hexametaphosphate is added in the paper production process. Industrial 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.


Industrial 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 industrial grade sodium hexametaphosphate dispersant not only has the function of dispersing but also the function of complexing agent. Because industrial 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 industrial grade sodium hexametaphosphate as a dispersant is improved. Chongqing Chuandong Chemical Group, the manufacturer of industrial grade sodium hexametaphosphate in China using thermal phosphoric acid, is more professional in its production quality.

The factory tells you food grade sodium tripolyphosphate/STPP requires heavy metal purification

Condiments, meat products, edible oil, dairy products, drinks, etc. are all necessities of daily life. Some food additives will be used in the production and processing process. The use of additives also makes people more concerned about "safety on the tip of the tongue".  Sodium tripolyphosphate/STPP  is widely used in food additives. Chongqing Chuandong Chemical Group will show you the main applications of sodium tripolyphosphate/STPP in the food industry: 1. Food grade sodium tripolyphosphate is used in meat products, fish sausage, ham, etc., which can improve the water holding capacity, increase the cohesiveness and prevent fat oxidation; 2. For fruit drinks and cool drinks, it can improve the juice yield, increase the viscosity and inhibit the decomposition of vitamin C. 3. It can prevent discoloration, increase viscosity, shorten fermentation period and adjust taste when used in soybean paste and soy sauce. 4. For ice cream, it can improve the expansion capacity, increa

What is the use of calcium formate industrial grade in construction? The manufacturer tells you

  With the development of the city's economy, the construction of highways, bridges, tunnels, and civil construction projects will require stricter use of early strength agents. Especially in winter, in order to improve the construction period, the cement mortar needs to be raised as soon as possible and put into use.   Calcium formate industrial grade   is a good early strength agent. Although both calcium formate and calcium chloride are calcium salts, relatively speaking, the performance of calcium formate is more stable. Because the formic acid in calcium formate is a weak acid. The solution will be weakly alkaline during the hydrolysis in the aqueous solution. It can be widely used in mortar. Calcium formate industrial grade is now a newly developed low temperature early strength accelerator in China, which has been widely used in various construction cement mortars. The earliest known and used chlorine salt early strength agent in construction, but the chloride salt early str

The effect of calcium supplement with feed grade calcium formate is good when crops are short of calcium

  Is it true that crops also need calcium supplements? it is true. Crops are plants, like humans and animals, that need rich trace elements to help them grow. When crops are calcium-deficient, plant growth is hindered, and the internodes are shorter, so they are generally shorter than normal plants and have soft tissues. Since calcium has such a big effect, is it good to use   feed grade calcium formate   to supplement calcium? The meristems such as the apical buds, lateral buds, and root tips of crops with calcium-deficient plants first appear nutrient deficiency, which is perishable, the young leaves are curled and deformed, and the leaf edges begin to turn yellow and become necrotic. For example, calcium deficiency can cause leaf scorch disease in cabbage, cabbage and lettuce; tomato, pepper, watermelon, etc. have heart rot; apples have bitter pox and water heart disease. No matter how much is useless, the crops are short of calcium. If we want to achieve the actual effect, what sho
