Using method of cationic Polyacrylamide:
1, when using, with 0.1 0.3% concentration of aqueous solution, to use neutral excluding salt sundry water is advisable.
2, when dissolved, this series of products will stir evenly into the water, stirring speed control in 100-300 RPM, proper heating (< 60 ℃), can accelerate the dissolve.
3, adjust the treated liquid PH value, give full play to the role of this series of products (through the test to choose the best PH value and the amount of the series of products).
4, add in the series of products, should accelerate and treated liquid mixing, appear after the floc, slow stirring speed, eli floc growth and accelerate the settlement.
5, is stable at room temperature, high temperature, frozen when easy degradation, and reduce the flocculation effect. So its storage and configuration for overtime, shall not exceed 65 ℃ temperature, indoor temperature is not less than 2 ℃.
