Polyacrylamide is a polymer flocculant widely used in the water purification market. It is also often used as a coagulant. The raw material of polyacrylamide is made of: polyacrylonitrile. In certain Under the environment, acrylamide can be converted into acrylamide through the process of hydrolysis, and finally polyacrylamide is formed through suspension polymerization.
Polyacrylamide is a polymer flocculant widely used in the water purification market. It is also often used as a coagulant. The raw material of polyacrylamide is made of polyacrylonitrile. Under the environment, acrylamide can become acrylamide through the process of hydrolysis, and finally polyacrylamide is formed through suspension polymerization. Therefore, polyacrylamide is called: water-soluble resin, which is divided into two types: solid and liquid. When it exists as a liquid, it has a certain viscosity.
Anionic polyacrylamide has an amide group, which can be attached to the surface of sediment particles through hydrogen bonding. Anionic polyacrylamide has a long molecular chain, and a large number of long chains describe the surface of a huge group. This achieves a very good flocculation effect, using molecular chains to directly bridge and link each other to form a strong floc, thus achieving a water purification effect.
Anionic Polyacrylamide
Molecular weight of anionic polyacrylamide: As an industrial sewage treatment agent, the molecular weight is between 6 million and 18 million. The misunderstanding we need to understand: It is not that the higher the molecular weight, the better the effect of treating sewage. When used as a water treatment agent, the molecular weight is between The molecular weight is between 4 million and 18 million. When used as a thickener, the molecular weight is between 18 million and 25 million. Specifically, the specific type of polyacrylamide must be selected based on various indicators of different sewage.
Another very important indicator of anionic polyacrylamide is: degree of hydrolysis. Currently, the market can be divided into four specifications according to the degree of hydrolysis: medium hydrolysis anionic polyacrylamide, hydrolysis degree: 23%-27%; medium and low hydrolysis anionic polyacrylamide, hydrolysis degree: 17%-19%; low hydrolysis anionic Polyacrylamide, degree of hydrolysis: 12%-15%; highly hydrolyzed anionic polyacrylamide, degree of hydrolysis: about 37%.
