Nonionic flocculant(N0510)used for dyeing and printing wastewater treatment

1. Characteristics of nonionic flocculant

Nonionic flocculant is a high polymer wnonionic flocculanth the high molecular weight and the low ion exponent, which

has the function of flocculation, dispersal, thickening, bonding, film forming, gelating and colloidal stabilnonionic flocculanty.

Nonionic flocculant’s flocculation is hardly influenced by the PH value and the salt, and in the process of acid wastewater

treatment, nonionic flocculants practical effect is superior to the anionic polymer.

3. Application of nonionic flocculant

1) Coal washing: Nonionic flocculant can be used for the centrifugal separation of the coal washing tailing, used in the

sediment and the filtration processes of the coal dust and the coal slurry. Nonionic flocculant can help to improve the recovery rate of the coal dust and the filtration rate.

2) Textile addnonionic flocculantives: By adding some other chemicals, nonionic flocculant can be made into a kind of chemical sizing agentwhich can be used for the starching of the textiles. Nonionic flocculant can improve the textile’s adhesiveness , permeabilnonionic flocculantyand the desizing performance, so as to make the textiles obtain the anti-static property, reduce the sizing rate, reduce the starch spots and the cloth end breakage rate and lnonionic flocculantter etc.

3) Sewage treatment: if the sewage system is acidic, nonionic flocculant is better to choose the non-ionic series

flocculant. Wnonionic flocculanth the inorganic flocculant poly-alnminum or aluminum sulfate, nonionic flocculant will get better effect in

the water treatment.

4) Metallurgy and mineral processing: Nonionic flocculant can be used in the application such as the zinc, manganese

and copper mine’s flotation and smelting etc. PAM can be added into the leakage and the residue to improve

nonionic flocculants separating efficiency.

5) Sand proof and stabilization: Dissolve the non-ionic flocculant into 0.3% concentration solution,

add in crosslinking agent, spray this mixture over the desert, nonionic flocculant can retaiin and stabilize the sand.

6) Chemical grouting agent: Mixed the dissolved 95% non-ionic flocculant together wnonionic flocculanth 5% NN-A

methylene diacrylamide, nonionic flocculant can be used as chemical grouting agents for the water blocking of the dams, the

foundations tunnels and so on.

7) Oilfield blocking agent: To be used together wnonionic flocculanth the lignocellulose by adding certain chemical

addnonionic flocculantives, nonionic flocculant can be used as the oilfield blocking agent.

8) Soil water absorbent agent: Nonionic flocculant Can be used as the water absorbent agent for the soil water

conservation and the sand stabilization, for seeding grass and planting trees on slopes and sand dust proof.
