As a lubricant, suspending agent, clay stabiliser, oil repellent, water loss reduction agent and thickener, polyacrylamide is widely used in drilling, acidification, fracturing, water plugging, well cementing and secondary and tertiary oil recovery, and it is a kind of extremely important oilfield chemicals.
Polyacrylamide has good thermal stability, easily soluble in cold water, the viscosity of its aqueous solution and the concentration of the approximate logarithmic relationship (i.e., a straight line relationship), high relative molecular mass and ultra-high relative molecular mass (greater than 2000 × 10) Polyacrylamide (PAM) has a very high viscosity, and its aqueous solution has a very good tolerance for electrolytes.
Polyacrylamide flocculation effect is excellent, because it has:
1.clarification and purification; 2.settlement promotion; 3.filtration promotion; 4.thickening (thick) and other roles.Commonly used in sewage treatment.Sludge dewatering.Drilling fluid additives. Mineral processing.Coal washing. Paper making and so on.
Usually, according to the characteristics of the product,Polyacrylamide is divided into: anionic,cationic,non-ionic,amphoteric,a variety of specifications to meet a variety of sewage treatment needs.There are also many people will be directly based on the state, such as powder,liquid,solid.
