Cationic polyacrylamide (CPAM) is a linear polymer compound. Because it has many active groups, it can form hydrogen bonds with many substances through affinity and adsorption. The main flocculation of negatively charged colloid, with turbidity removal, decolorization, adsorption, adhesion and other functions. Suitable for printing and dyeing, papermaking, food, alcohol, chemical, pharmaceutical and other industries of wastewater treatment, especially suitable for municipal sewage treatment plant sludge treatment and papermaking sludge and other industrial sludge dehydration. Cationic polyacrylamide usually has some indicators, such as molecular weight, solid content, ionic degree, dissolution time, etc. In general, one of the most talked about metrics is ionic degree.
In addition to the importance of selection, the quality stability of cationic polyacrylamide is also very important. At present, most manufacturers do not do very well in terms of stability. Due to the influence of some factors in the production process, the product is prone to errors, so the stability of cationic polyacrylamide in the production process is difficult to control, poor stability will affect the use of products. In many cases, these products also circulate to the market due to cost considerations. So if there is a link to the circulation of these products to the market for supervision and testing, basically can ensure the stability of quality. However, as an end customer, this capability is rarely available.
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
