1. Storage Time

The viscosity of water treatment flocculants will increase with the storage time, the more degradation, the lower, the worse the flocculation effect. This is mainly due to the hydrolysis of the amide group and the increase of hydroxyl content. Especially the effect of containing cationic groups will be more obvious, the amide group de NH3 generated by the imide group is due to the increase in the rigidity of the molecular chain.

2. Mechanical Effect

• Stirring can improve the dissolution speed of PAM flocculant dry powder, high speed stirring speed, will cut the molecular chain of PAM, it is recommended to control the stirring speed at line speed 60 rpm, do not use high intensity stirring equipment and high speed conveying equipment.
• Stirring can improve the dissolution speed of PAM flocculant dry powder, high-speed stirring speed, will shorten the molecular chain of PAM, it is recommended to control the stirring speed at line speed 60 rpm, do not use high-intensity stirring equipment and high-speed conveying equipment.

3. The Effect of Temperature

0.1% PAM solution, at a temperature of 80 ℃ -90 ℃, 18 million molecular weight in 2-4 hours will degrade to about 5 million, with the increase in temperature, the faster the degradation. The performance is stable at room temperature 25℃.

4. The Influence of Light.

Light will increase the temperature and degrade the solubility of PAM, and direct exposure to UV light will cause rapid degradation of solubility.

5. The Effect of Impurities.

Dissolve the dry powder of PAM, use neutral water, the hardness of water, or contain impurities, will affect the viscosity of water treatment flocculants and the use of the effect.
