Deinking Processing Polyacrylamide
1, Product characteristics
This product is a cationic monomer and acrylamide copolymer formed in different proportions, is a water-soluble polymers. Adsorption of colloidal or suspended particles of water, electricity, bridges, parcels and other role, so that coagulate into a thick floc, so as to improve and accelerate the solid - liquid separation processes, including sedimentation, clarification, concentration and dehydration process.
2,Specification

3, Application
1, It mostly used for municipal sewage and industrial organic wastewater treatment, showed a cationic in acidic or alkaline medium, sewage flocculation and sedimentation of suspended particles with a negative charge, to clarify the extremely effective.
2, Sludge dewatering, sludge nature of the choice of the corresponding models of the product to be effective in the sludge into the dehydrated mechanical gravity sludge dewatering. Dehydration of the product is used to produce large floc, non-stick cloth, not dispersed in the filter press, with less dehydration and high efficiency, the cake moisture content up to 80%.
3, For surface water water water plant water treatment flocculant. With less, effective, low cost, and inorganic flocculants used in conjunction with the better.
4, In the paper industry for paper dry strength agents, retention agents, filter aids can greatly improve the paper quality, cost savings, improve the production capacity of paper mills. Electrostatic role as a bridge directly with the inorganic ions, fiber and other organic polymer in order to achieve enhanced paper physical strength, reduce the loss of fibers or fillers to speed up treatment, since enhanced, flow aid, the role of filter aids can also be used the handling of the Whitewater, in the deinking process can play a significant flocculation effect.
5, Usage
1, when used should generally be dubbed a 0.1-0.3% aqueous solution of water is appropriate to use the neutral does not contain salts debris;
2,Putting the powder slowly evenly thrown into the mixing water in order to ensure its good dispersion in water, swelling (do not put dry powder and then add water) before adding the powder, and will not form a "fish eyes" or blockage of the dosing pipe, the occurrence of operation failure . Stir speed control in the 100-300rpm;
3, The solution of the product of the Department shall be equipped with ready to use, configured to be placed not more than one day, when the preparation, transfer, storage of this product, contact with the solution best equipped with stainless steel, plastic, glass and steel;
4, The line products in line with the inorganic coagulant, should join the inorganic coagulant, to be obvious alum (it usually takes about 20-60 seconds), then add to this series of products, not in reverse order , can not be joined together;
5, Dissolution good flocculant application of screw pumps, diaphragm pumps and low shear conveying equipment, into the sludge dehydrating agent.
6, Notes
1, the operator should wear protective equipment, skin contact, wash water;
2, The use of the site, if a small amount of leakage that can be used a lot of water rinse; such as a large leak, the first shovel to sweep and then a lot of water to rinse, emergency first sprinkled with a lot of sand, to prevent slipping injuries;
3, this series should be sealed a cool dry place to prevent damp;
4, the storage period of one year.
