PHPA anionic polyacrylamide (HS:390690) for use in water treatment and mining

Performance characteristics:

1, polyacrylamide molecules have positive genes, strong flocculation ability, less dosage, obvious treatment effect.

2. Good solubility, high activity, large volume of alum formed by condensation in water, fast settlement. The purification capacity is 2-3 times that of other water-soluble polymers. 3, strong adaptability, by the water PH value and temperature influence is small, raw water purification to the national reference water standard, after treatment of suspended particles in water to achieve the purpose of flocculation and clarification, conducive to ion exchange treatment and preparation of high pure water.

4, corrosion is small, easy to operate, can improve the labor intensity and working conditions of dosing process.

Polyacrylamide application range

Polyacrylamide molecules contain positive genes (-CONH2) that absorb and bridge suspended particles dispersed in solution. It has strong flocculation, can accelerate the sedimentation of particles in suspension, and has a very obvious effect of speeding up solution clarification and promoting filtration. Therefore, it is widely used in water treatment and power, mining, coal preparation, asbestos products, petrochemical, paper making, textile, sugar, medicine, environmental protection and other fields.

1. As a flocculant, it is mainly used in the process of industrial solid-liquid separation, including sedimentation, clarification, concentration and sludge dewatering and other technologies. The main industries of application are: urban sewage treatment, papermaking industry, food processing, petrochemical industry, metallurgy industry, processing industry, dyeing industry, sugar industry and various industrial wastewater treatment. Used for municipal sewage and meat, poultry, food processing wastewater treatment process sludge precipitation and sludge dehydration, the use of its organic colloidal electric group on sludge negative charge neutralization and excellent polymer bridge coagulation function, promote colloidal particles aggregated into large flocs, separated from the slurry. The effect is obvious, the dosage is small.

2, in the paper industry can be used as paper dry strength agent, retention agent, filter agent, can greatly improve the quality of paper, cost saving, improve the production capacity of paper mill. Can directly and inorganic ions, fibers and other organic polymers electrostatic bridge effect to improve the physical strength of paper, reduce the loss of fibers or fillers, speed up water filtration, improve, help to stay, help to filter, can also be used for white water treatment, at the same time, in the process of deinking can play a significant flocculation.

3, fiber mud (asbestos cement products) can improve the formation of asbestos cement products drainage, so that the strength of asbestos board is improved; In insulation panels, the combination of additives and fibers can be improved.

4, in the mine, coal preparation industry can be used as mine wastewater, coal washing wastewater clarification agent.

5, can be used for printing and dyeing wastewater, leather wastewater, oily wastewater treatment, turbidity removal, decolorization, in order to meet the discharge standard.

6. In the process of phosphoric acid purification, it is beneficial to the separation of gypsum in the wet phosphoric acid process.

7. Flocculant for water treatment of river source water plant.

Use and preventive measures:

1. Solution of 0.2% concentration is suitable for neutral water without salt.

2. Because this product is suitable for a wide range of PH value of water, the general dosage is 0.1-10ppm (0.1-10mg/L).

3. Dissolve completely. When the water dissolves, it needs to be stirred thoroughly and then the powder is added slowly and evenly to prevent clogging the pipes and pumps, causing large flocculation and fisheye phenomenon.

4. Stirring speed of 200 RPM is generally appropriate, the time is not less than 60 minutes, appropriately raise the water temperature 20-30 degrees Celsius, can accelerate the dissolution. The maximum temperature of the solution should be less than 60 degrees.

5. Determine the optimal dose. Determine the optimal dosage through experiments before use. Because the dosage is too low, does not work, the dosage is too high, but has the opposite effect, more than a certain concentration, PAM not only does not flocculate, and dispersed and stable use.

6. The product should be stored in a cool and dry place to prevent dampness.

7. The workplace should be cleaned and kept clean frequently. PAM disperses the surface smooth due to its large viscosity, preventing the operator from slipping and causing safety accidents.

8. This product is lined with plastic bags, outer plastic film woven bags, each bag 25Kg.
