Cationic polyacrylamide is a linear polymer compound. Because it has various active groups, it can form hydrogen bonds with many substances. It is mainly flocculated with negatively charged colloid, with turbidity, decolorization, adsorption, bonding and other functions. Cationic polyacrylamide is suitable for dyeing, paper making, food, construction, metallurgy, mineral processing, coal powder, oil fields, aquatic processing and fermentation industries with high organic colloid content of wastewater treatment, especially suitable for urban sewage, urban sludge, paper sludge and other industrial sludge dewatering treatment.
Cationic polyacrylamide Features:
First, it is water-soluble and can be dissolved in cold water. Good water solubility: good water solubility, high degree of hydrolysis (ionic degree). The so-called degree of hydrolysis refers to the ability of weak ions in the polyacrylamide solution to combine with water to form weak alkalinity or weak acidity, or the ability of weak acidity and weak alkalinity in the polyacrylamide solution. For strong acids and bases, the greater the degree of ionization, the stronger the corresponding acid-base, the weaker the degree of hydrolysis. For some soluble polyacrylamides, the greater the degree of ionization, the more ionized ions, the weaker the degree of hydrolysis. Generally, the higher the degree of ionization, the weaker the degree of hydrolysis. On the contrary, the degree of hydrolysis is higher when the degree of ionization is lower.
Second, adding a small amount of cationic polyacrylamide products can obtain great flocculation effect. Generally, only 0.01~10ppm(0.01~10g/m3) can be added to play a full role.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
