Product description

1. Product Description:

This product is a kind of water-soluble polymer, which is copolymerized by cationic monomer and acrylamide in different proportions. It can adsorb, neutralize, bridge and wrap colloids or suspended particles in water to form large and compact flocs with low water content, so as to improve and accelerate the solid-liquid separation process, including sedimentation, clarification, thickening and sludge dewatering. This product is suitable for the treatment of urban domestic sewage and industrial organic wastewater. It has positive electricity in acidic or alkaline medium. It is very effective for flocculation, sedimentation and clarification of wastewater with negative charge; Used for sludge dewatering. According to the sludge properties, the corresponding model of this product can be selected, which can effectively carry out gravity sludge dewatering before the sludge enters the dewatering machine. When the product is used for dehydration, it can produce large flocs, not stick to the filter cloth, not flow when pressing filter, with less consumption and high dehydration efficiency, and the moisture content of mud cake can reach below 80%; It is used as flocculant for water treatment of waterworks with surface water as water source. The utility model has the advantages of less dosage, good effect and low cost. In particular, the effect is better when combined with inorganic flocculant; In papermaking industry, Cationic PAM Paper Reinforcer can directly react with inorganic salt ions and fibers; And other organic polymers have electrostatic bridging effect to enhance the physical strength of the paper, reduce the loss of fiber or filler, speed up the filtration, and play the role of reinforcement, retention and filtration. It can also be used for white water treatment and has obvious flocculation effect in deinking process.

3. Application Description:

In general, it should be mixed with 0.1-0.4% aqueous solution, and neutral water without salt impurities should be used; The dry powder of the product is slowly and evenly sprinkled into the mixing water to ensure its good dispersion and swelling in the water (avoid adding dry powder first and then adding water), so as not to form "fisheye" or block the dosing pipeline, resulting in operation failure. The stirring speed is controlled at 100-300 rpm; The solution of this series of products should be ready for use, and should not be placed for more than one day after preparation. When preparing, transferring and storing this product, the equipment in contact with the solution should preferably be made of stainless steel, plastic, glass or FRP; When this series of products are combined with inorganic coagulant, the inorganic coagulant should be added first, and then the series of products should be added when there is obvious alum bloom (generally, the interval time is about 30-60 seconds); It can not be added at the same time; The dissolved flocculant should be transported by screw pump, diaphragm pump and other low shear pumps.

 

4. Safety protection:

Operators should wear protective equipment and wash with water after skin contact; If there is a small amount of leakage in the use site, it can be washed with a large amount of water; If there is a large amount of leakage, first sweep and then rinse with a large amount of water.

 

5. Packaging and storage: 25kg / bag or according to the user's requirements; Sealed in a cool and dry place to prevent moisture; It is valid for 12 months.
