Polyacrylamide for printing and dyeing (MagnafloC 355)

 

Special printing and dyeing polyacrylamide is my company according to the characteristics of printing and dyeing wastewater, developed a series of special type products, its main principle was added to the printing and dyeing wastewater, aqueous solution through electrical neutralization and inherent in polymer adsorption bridging role, suspended particles can rapid agglutination of precipitation, and achieve the effect of separation, clarification, Printing and dyeing factory special polyacrylamide can effectively solve the textile printing and dyeing factory wastewater treatment problems, increase the recycling rate of water or standard discharge.

【 Characteristics of polyacrylamide products used in printing and dyeing factories 】 :

 

1. Flocculation:

 

PAM used for flocculation, and flocculated species surface properties, especially when the potential, viscosity, turbidity and suspension PH value, the particle surface potential, is the cause of particle resistance to polymerization adding surface charge opposite PAM, can reduce the potential and condensation.

 

2, adsorption bridge:

 

PAM molecular chain is fixed on the surface of different particles, the formation of polymer bridge between the particles, so that the particles form aggregates and settlement.

 

3, surface adsorption:

 

Various kinds of adsorption of very functional group particles on PAM molecular chain.

 

4. Enhanced effect:

 

PAM molecular chain and dispersed phase through a variety of mechanical, physical, chemical and other actions, the dispersed phase implicated together, forming a network.

 

[Notes for polyacrylamide dissolution in printing and dyeing factory] :

 

1, in the solution tank into 1/3 of the water, open the stirring switch, and then slowly symmetrical add solid polyacrylamide, add water while adding products, calculate the volume of the solution tank to add quantitative product dry powder.

 

2, solid products should be dissolved in clear water, there is no debris in the water, not to use sewage to dissolve, dissolve with normal temperature water, high water temperature should not exceed 60 degrees. Because the higher the water temperature will accelerate the dissolution of polyacrylamide flocculant, easy to destroy the product performance.

 

3, adding polyacrylamide dry powder must be slowly added to the water, can not be dumped, dumped in the water is easy to form a transparent colloid, external light and internal dry waste.

 

4, the stirring speed is not easy to be too fast, the motor control speed is 60 RPM /m, too fast speed will break the polyacrylamide molecular chain, directly reduce the product effect.

 

5, polyacrylamide dissolved concentration in 1-3 ‰ ideal, low concentration of dissolved flow pump high volume, high concentration of dissolved in metering pumps dosing is hard, when the molecular chain has failed to give full play to the role, or form a jelly, will reduce the use effect, so when using polyacrylamide powder should be according to equipment reasonable adjustment of a certain concentration.
