Polyacrylamide is, simply called PAM, a water- soluble high polymer and widely used in petroleum, paper-making, metallurgical, textile, chemical and environment protection fields. There are three categories of anionic, cationic and non-ionic type.
Application introduction
PAM series products contain affinity radical and they can dissolve in water easily and play the role of flocculation, filtering-assist, increasing adherence, reducing resistance, coherence, reinforcing and rheologic regulation and can be used extensively. Flocculation property can be used for recovering solid substance, treating various industrial sewage, domestic sewage and purifying water, assisting filtering, treatment of tail coal as well as well-drilling slurry material etc. with the rheologic regulation function PAM can thicken water recover driving agent for oil field to reform ground section, enhance adoption ratio.
It can make up fracturing solution to fracture the stratum which is difficult to drill and it also can make up well-drilling solution which can reduce friction and resistance, accelerate drilling speed, improve drilling depth. with the property of adherence and reinforcing of PAM, it can be used for paper-making industry to enhance staying rate of filling material, speed size filterability and white water sediment in the paper and then coagulate to increase the strength of the paper. PAM can be used with polyvinyl alcohol as textile size, this can improve textile process and enhance the property of textile.
Grades
Cationic PAM, cationicity 0-100%, molecular weight 4-10million
Anionic PAM, anionicity0-100%, molecular weight15-20million
Nononic PAM, molecular weight 10-15 million
Usage
When use PAM series products, first make up dilute solution, usually 0.01%-0.1%, thus it is easy to mix with treated substance to get the best result.
