　　Cationic polyacrylamide is used by many sewage plants to treat sludge in inorganic sewage due to its special properties. Let us understand its chemical properties below.

　　Cationic polyacrylamide

　　Cationic polyacrylamide is a linear polymer polymerized by acrylamide. It has the function of reducing the frictional resistance between the characteristic points of liquid ions, so it has a very good flocculation effect and has been used in sewage treatment for a long time. It is insoluble to organic solvents such as methanol, acetone, and ether, but there are some special solvents such as acetic acid, acrylic acid, chloroacetic acid and other solvents that are soluble, but if you want to dissolve in these solutions fully, you need to heat it. Can not be fully dissolved.

　　Cationic polyacrylamide generally exists in a network structure at low concentrations, and becomes gelatinous at high concentrations. The aqueous solution of cationic polyacrylamide has good compatibility with organic substances that can be dissolved in water. In addition, it has good compatibility with electrolytes such as potassium hydroxide, sodium carbonate and sodium borate.
