Oil field
The
tertiary oil recovery with the core technology of polyacrylamide flooding to
improve oil recovery will become the dominant development mode of the oilfield
and enter a period of rapid development. Polyacrylamide are mainly used for tertiary
oil recovery, profile control and water shutoff, drilling fluid.

Mining industry
Polyacrylamide is used in the mining and processing of coal, gold, silver, copper, iron, lead-zinc, aluminium, uranium, nickel, phosphorus, potassium, manganese, salt and tailings treatment process. The main purpose is to improve the efficiency and recovery of solid-liquid separation. In coal industry, the settling and clarification of coal slurry, tailings filtration and centrifugation. It is the settling agent added by the concentrator before the filter tank in the field of gold, silver and copper ores. In bauxite, when sodium aluminate solution is separated from red mud, an additive is added in the washing process to promote the rapid settling of red mud particles and obtain the required clarification overflow.
