Cationic Polyacrylamide Multiple Effect
Sep 27, 2017

Cationic polyacrylamide (CPAM) is a linear polymer compound, because it has a variety of active groups, which can be bonded with many substances and adsorbed to form hydrogen bonds. Mainly flocculation negatively charged colloid, except the turbidity, decoloring, adsorption, adhesion, and other functions, suitable for dyeing, papermaking, food, building, metallurgy, mineral processing, coal, oil field, aquatic products processing and fermentation industries such as waste water treatment of organic colloid content is higher, especially suitable for urban sewage, urban sewage sludge, sludge and other industrial sludge dewatering treatment.

Degree of hydrolysis

Degree of hydrolysis polyacrylamide refers to the weak ion polyacrylamide solution combined with water, the formation of weak alkaline or the ability of weak acid, or is formed in the PAM aqueous solution of the strength of weak acid and weak base ability strong or weak. For strong acids and strong bases, the greater the ionization degree, the stronger the acidity, and the weaker the degree of hydrolysis. For some soluble polyacrylamide, the greater the ionization degree, the less the degree of hydrolysis. In general, the degree of dissociation is greater, and the degree of hydrolysis is much smaller.

Multiple functions of cationic polyacrylamide CPAM flocculant

There are many kinds of cationic polyacrylamide, which can process all kinds of sewage, and the flocculation is quick and effective. Now, the novel is explained in detail: the multiple functions of cationic polyacrylamide.

1, as a flocculant, cationic polyacrylamide (CPAM) is mainly used in industrial solid-liquid separation process, including settlement, clarification, concentration and sludge dewatering technology, application of the main industries are: urban sewage treatment, paper industry, food processing, petrochemical industry, metallurgical industry, processing industry, dyeing industry and sugar industry and all kinds of industrial wastewater treatment. Polyacrylamide (CPAM) is used for sludge deposition and sludge dehydration in municipal sewage and meat, poultry and food processing wastewater treatment.

2, in the papermaking industry of cationic polyacrylamide (CPAM) can be used as paper dry strength agents, retention agent, filter aid, can greatly improve the quality of the paper, cost savings, improve the production ability of paper mill. Can be directly with inorganic salt ions, fiber, and other organic polymer electrostatic bridge so as to enhance the physical strength of paper, and reduce the loss of fiber or filler to accelerate the filtering, enhancement and retention, leaching effect, can also be used for water treatment, at the same time, in the deinking process can a obvious flocculation effect.

3. The fiber mud (asbestos - cement products) can improve the water quality of the forming asbestos - cement products and improve the strength of asbestos slab materials. Cationic polyacrylamide (CPAM) can enhance the binding capacity of additives and fiber in insulating plates.

4. Cationic polyacrylamide (CPAM) can be used as a clarification agent in mining wastewater and coal washing wastewater.

5. It can be used for treatment of dyeing wastewater, leather wastewater and oily waste water, so as to remove turbidity and discoloration to meet the emission standards.

6. In phosphate purification, cationic polyacrylamide (CPAM) contributes to the separation of gypsum from wet process.

7. Water treatment flocculant used in waterworks with rivers and rivers. Low dosage, good effect, low cost. Especially with inorganic flocculant compound use effect is better. It will be a high-efficiency flocculant along the Yangtze river, the Yellow River and other river basins.
