Nonionic polyacrylamide is a kind of water soluble polymer, different from cationic polyacrylamide, its chemical structure does not contain ionic bond. It is usually a linear macromolecule, can form hydrolytic stable polymer solution, has excellent viscosity regulation properties and biocompatibility, has been widely used in biomedicine, food, metallurgy and other fields.
In the field of biomedicine, nonionic polyacrylamide is an important biocompatible polymer material, which is widely used in the preparation of medical materials. Due to its excellent biocompatibility and biodegradability, nonionic polyacrylamide can be used as the basic material for medical graft polymers, drug sustained-release agents and repair materials.
In the field of food, non-ionic polyacrylamide can be used as a food additive for thickening, emulsifying, stabilizing, dispersing and so on. It can improve the texture and taste of food, increase the water retention of food, improve the quality and shelf life of food. Nonionic polyacrylamide can also be used in the production of beverages, jams, salad dressings, ice cream and other foods.
In metallurgy, nonionic polyacrylamide can be used as a flotation agent for mineral selection and solid liquid phase separation. It can form a protective film on the surface of minerals, increase the contact area between minerals and bubbles, and improve the flotation speed and flotation rate of minerals. Non-ionic polyacrylamide can also be used in the preparation of metal working fluids to improve the lubricity and stability of metal working fluids.
In general, non-ionic polyacrylamide is widely used in various fields, and its excellent characteristics provide convenience and assistance for many production processes. With the continuous development of science and technology, it is believed that non-ionic polyacrylamide will be widely used in more fields.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
