LH-750 Anionic polyacrylamide (APAM)
◇Chemical composition
[CH2-CH]n-CONH2
◇Product performance
Anionic polyacrylamide products use the method that acrylamide add alkali gathered together before hydrolysis process, forming after the granulation, drying, and crushing, the appearance of the product is white tiny particles or powder solid. （APAM）appearance is white powder, molecular amount is from 600 million to 25 million, it is well water-soluble, It can take arbitrary proportion soluble in water and insoluble in organic solvents. Its effective PH value scope is 7 to 14; In a neutral alkaline medium it has high polymer electrolyte properties, it is sensitive to salts electrolyte, it can form of insoluble gel with high metal ions.
◇Product features
1) Flocculability: PAM can make the suspended material form flocculation effect through electric neutralization and bridging adsorption effect.
2) Adhesiveness: It can form the bonding effect through the mechanical, physical and chemical action.
3) Friction reduction: PAM can effectively reduce the frictional resistance of the fluid, adding slight PAM into the water can dray reduction of 50-80 percent.
4) Thickening: PAM has thickening functions in a neutral or acid condition, while PH is above PAM can be easily hydrolyzed, when it is half mesh structure, thickening will be more apparent.

◇Method of use:
1) When using it, match it into water solution with a consistence of 0.1-0.3%, using neuter sundry excluding salts water is advisable.
2) When dissolving, scatter this series product in a balance in to the mix of water, Stirring speed should be controlled under the 100-300rpm. Proper heating (< 60 ℃), can accelerate to dissolve.
3) Adjust the disposed liquid PH value; make this product series play its role completely. (You can choose the best PH value through experiment and the dosage of the series products)
4) When adding this series product solution, should speed mixing with the disposed liquid up, after floc property appears, stir slowly, to be beneficial for the Eli floc properties increasingly surrogate and accelerate the settlement.
◇Packing and storage:
It should be packed with Kraft bags that are 5kg or 25kg, lined with Plastic moisture-proof film inside. Its storage period is two years.
