Advantages of non-ionic polyacrylamide mainly used as a flocculant.
Because its molecular chain contains a certain amount of polar genes which can
adsorb suspended solid particles in water, the particles are interbridged to form
large flocculates.
Non-ionic polyacrylamide can accelerate the settlement of the particles in the
suspension, has a very obvious speed up the clarification of the solution, promote
filtration and other effects, widely used in the chemical industry wastewater,
waste liquid treatment, municipal sewage treatment.
Especially when the sewage is acidic, the use of this product is most suitable.
Can be used with inorganic flocculants such as polyiron, polyaluminum and other
inorganic salts.

Application of Nonionic polyacrylamide:
1, coal mine washing;
It can be used for centrifugal sharing of coal washing tailings, and can be used in
the precipitation and filtration of pulverized coal and coal slime, which can
improve the recovery rate of pulverized coal and filtration rate, and improve the
water circulation rate.

2. Textile auxiliaries;
Adding some other chemicals can be prepared into chemical sizing, used for textile
sizing, can improve the adhesion, permeability and desizing performance, so that
the fabric has spinning electrostatic properties, reduce sizing rate, reduce skein
spots, cloth breaking rate and falling matter.

3. Sewage treatment;
When the sewage system is acidic, the selection of non-ionic series of
polyacrylamide is more appropriate, and inorganic flocculant polyaluminum, aluminum
sulfate and other use in conjunction, in the water treatment effect is better.

4. Metallurgical beneficiation;
For example, in the flotation and smelting of zinc, manganese and copper, the
leaching liquid and residue can be entered into PAM to improve the sharing
efficiency.

5, sand prevention and sand fixation;
The non-ionic polyacrylamide dissolved into 0.3% concentration to add crosslinking
agent, spraying on the desert can prevent and fix sand.

6, chemical grouting agent;
9.5 parts of non-ionic polyacrylamide and 0.5 parts of NN-- methylene diacrylamide
miscibility can be used as a chemical grouting agent for water plugging of DAMS,
foundations, tunnels and so on.

7, soil moisture agent;
It holds water and holds sand in the soil.
Hill planting grass, tree planting, sand and dust can play a role in moisturizing
agent.
