Product Features:  

1) Flocculation: PAM can neutralize suspended matter through electricity, bridging and adsorbing, and flocculate.

2) Adhesiveness: It can be used for adhesion through mechanical, physical and chemical action.

3) Resistance reduction: PAM can effectively reduce the frictional resistance of the fluid. Adding a small amount of PAM in the water can reduce the resistance by 50-80%.

4) Thickening: PAM has a thickening effect under neutral and acidic conditions. When the PH value is above 10, PAM is easily hydrolyzed and has a semi-network structure, the thickening will be more obvious.


The main purpose:  

Industrial wastewater treatment: For the sewage treatment of suspended particles, relatively high concentration, positively charged particles, neutral or alkaline pH value of the water, wastewater from iron and steel plants, wastewater from electroplating plants, metallurgical wastewater, and coal washing wastewater, the effect is Great.

Drinking water treatment: The water source of many water plants in my country comes from rivers. The content of silt and minerals is high and it is relatively turbid. Although it is filtered through sedimentation, it still cannot meet the requirements. Flocculants need to be added. The dosage is 1/of inorganic flocculants. 50, but the effect is several times that of inorganic flocculants. For rivers with serious organic pollution, inorganic flocculants can be used in conjunction with our company's cationic polyacrylamide to have a better effect.

Recovery of lost starch and distiller’s grains from starch plants and alcohol plants: Many starch plants now contain a lot of starch in wastewater, and anionic polyacrylamide is added to flocculate and precipitate the starch particles, and then the sediment is filtered by a filter press to become cakes It can be used as feed. The alcohol in the alcohol plant can also be dehydrated by anionic polyacrylamide and recovered by filtration. Used for river cement slurry settlement.


Technical index:  

Polyacrylamide

Appearance: solid polyacrylamide is white or yellowish particles or powder; colloidal polyacrylamide is colorless or yellowish transparent colloid.

Molecular weight: According to user requirements, the relative deviation from the nominal value is not more than 10%.

Hydrolysis degree: the relative difference between the nominal value and the nominal value is not more than 2%, or according to user requirements; non-ionic products, the degree of hydrolysis is not more than 5%.

Water treatment agent: polyacrylamide should also meet the requirements of the following table.


Introduction to the principle of action:  

1) The principle of flocculation: When PAM is used for flocculation, it is related to the surface properties of the flocculated substance, especially the dynamic potential, viscosity, turbidity and the pH value of the suspension. The dynamic potential on the surface of the particles is the reason for the particle inhibition. PAM with opposite surface charge can reduce the dynamic potential and condense.

2) Adsorption and bridging: PAM molecular chains are fixed on the surface of different particles, and polymer bridges are formed between the particles, so that the particles form aggregates and settle.

3) Surface adsorption: various adsorption of polar group particles on PAM molecules.

4) Reinforcement: PAM molecular chain and dispersed phase link the dispersed phase together through various mechanical, physical, chemical and other actions to form a network, thereby playing a reinforcement role.
