Polyacrylamide using methods which
1, when in use, into 0.1% the concentration of aqueous solutions, used to contain salts sundry neutral water is advisable.
2, melts, anionic polyacrylamide products evenly into the mixing water, stir speed control in 100~300rpm. Proper heating (< 60 ° c), can accelerate the dissolution.
3, adjust the PH value of the solution, the anionic polyacrylamide products are fully functional (by choice best PH value and amount of this series. )
4, adding anionic polyacrylamide solution, mixed with the fluid should be accelerated, after flocculation occurs, slowing stirring speed, to Floc growth and speed up the settlement.
