1, as a flocculant, cationic polyacrylamide used in industrial solid-liquid separation process, including settlement, clarification, concentration and sludge dehydration process, cationic polyacrylamide application of the main industries are: municipal sewage treatment, paper industry, food processing industry, petrochemical industry, metallurgy industry, mineral processing industry, dyeing industry and sugar industry and a variety of industrial wastewater treatment. Cationic polyacrylamide is also used in urban sewage and meat, poultry, food processing wastewater treatment process of sludge precipitation and sludge dehydration, through the positive charge group of the sludge in the negative charge of organic colloid electrical neutralization and polymer bridging condensation function, to promote colloidal particles gathered into large flocculent, separated from its suspension. The effect is more obvious and the dosage is less.

 

2, cationic polyacrylamide in the paper industry can be used as paper dry strength agent, retention aid, filter aid, can greatly improve the quality of paper, save costs, improve the production capacity of paper factory. Can be with inorganic salt ions, fibers and other organic polymer electrostatic bridge effect to enhance the physical strength of paper, reduce the loss of fibers or fillers, speed up the filter water, enhance, retention, filtration, can also be used for white water treatment, at the same time cationic polyacrylamide in the deinking process can play a more obvious flocculation effect.

 

3, cationic polyacrylamide on fiber mud (asbestos-cement products) can make the formation of asbestos-cement products drainage improved, improve the strength of asbestos slab material, in the insulation board, can improve the ability of additives and fiber combination.

 

4, cationic polyacrylamide in mining, coal preparation industry can be used as mine wastewater, coal washing wastewater clarifying agent.

 

5, cationic polyacrylamide can be used for dyeing wastewater, leather wastewater, oily wastewater treatment.

 

6, cationic polyacrylamide in phosphoric acid purification, contribute to the separation of gypsum in wet phosphoric acid process.

 

 

 

Cationic polyacrylamide method

 

1, cationic polyacrylamide is used, generally with 0.1-0.3% concentration of aqueous solution, to use neutral water without salt debris is appropriate.

 

2. When cationic polyacrylamide is dissolved, the cationic polyacrylamide products are evenly sprinkled into the stirring water, and the stirring speed is controlled at 100~300rpm. Proper heating (< 60°C) can accelerate the dissolution.

 

3, cationic polyacrylamide to adjust the PH value of the treated liquid, so that cationic polyacrylamide play a role (through the test to choose the PH value and the amount of this series of products.)

 

4. When adding cationic polyacrylamide product solution, it should accelerate the mixing of the treated liquid, and slow down the stirring after the appearance of the flocculant, so as to facilitate the growth of the flocculant and accelerate the settlement.
