Polyacrylamide (Polyacrylamide, referred to as PAM) is an important polymer synthetic material, which is widely used in industrial and agricultural fields. This article will introduce polyacrylamide and its detection indicators, including the physical properties, chemical properties, environmental safety, and common detection methods of PAM.
1. Physical properties
Polyacrylamide is a colorless crystal or white crystalline powder with a large molecular weight and is soluble in water and many organic solvents.It has a high degree of water absorption, hygroscopicity and adhesion, and is an excellent hygroscopic resin.
2. Chemical properties
Polyacrylamide molecules contain amide groups, which have good stability and chemical reaction activity.When the conditions are appropriate, the degree of polymerization and molecular weight can be adjusted by changing the reaction conditions (such as temperature, time, solvent type, etc.).
3. Environmental safety
During the use of polyacrylamide, attention should be paid to environmental safety.According to international safety standards, PAM is considered to be a non-toxic, harmless, and non-polluting substance.
