The effect of polyacrylamide is related to water temperature

  • 4 October,2019

The use effect of polyacrylamide is also related to water temperature. The reaction speed is too slow at low water temperature, the hydrolysis time increases, affecting the water amount of treatment, and the tear action of high viscosity on flocculant will also make the flocculant become small. The reaction speed is too fast at high water temperature, forming small flocs.


Under normal circumstances, the use of polyacrylamide will increase the amount of flocculation effect and improve, but when the amount of excessive will make the effect become low, re-become a stable gel.




The second is flocculation time. When organic flocculant and inorganic flocculant are used together, the biggest characteristic of them is that the flocculant with the largest particle can be obtained and the oil drops can be agglutinated or adsorbed out.Too slow, too short time, flocculant can not fully contact with solid particles, not conducive to flocculant collecting colloidal particles; Moreover, the concentration distribution of flocculant is uneven, which is not conducive to the function of flocculant.


Polyacrylamide is an important water-soluble polymer with valuable properties of flocculation, thickening, shear resistance, resistance reduction and dispersion.These properties vary from derivative ion to derivative ion.Therefore, it is widely used in oil extraction, mineral processing, coal washing, metallurgy, chemical industry, paper making, textile, sugar making, medicine, environmental protection, building materials, agricultural production and other sectors.
