Yuhengyuan Production Polyacrylamide PAM Cationic Polyacrylamide Manufacturer Price

When polyacrylamide aqueous solution is placed for a long time, its viscosity gradually decreases, which affects its performance and increases the difficulty of determining solution performance It is generally believed that this is the reason for the degradation reaction of macromolecular chains under oxidation. Light, heat, and mechanical effects can also trigger degradation. The polyacrylamide solution undergoes significant shear degradation during the pumping or underground flow process, and the degree of shear degradation is related to its molecular weight. The presence of microorganisms can corrode polyacrylamide, which is a non-specific enzyme system based on the degradation of complex structural polymers by fungi.

The aqueous solution of polyacrylamide is prone to aging after prolonged storage, and its viscosity also decreases, resulting in poor performance and impact. When the polyacrylamide solution needs to be stored for a long time, an appropriate amount of stabilizer should be added to prevent it from being oxidized and degraded, otherwise it will affect its flocculation effect, indicating that the stability of the polyacrylamide solution is easily affected.

Polyacrylamide is usually packaged with Kraft paper moisture-proof packaging, and there must be one or two layers of moisture-proof treatment for good interior. This is because polyacrylamide is prone to moisture absorption and dampness, so its transportation and storage require certain moisture-proof measures. In general, vehicles transporting polyacrylamide must be tightly covered to prevent rain and leakage. And polyacrylamide should not be stored in damp places, and the storage time should not be too long. The storage of dry powder polyacrylamide should not exceed one year. The storage time of lotion polyacrylamide is shorter, which cannot exceed 6 months.
