Polyacrylamide

Polyacrylamide products of anion, cation, non-ion, zwitter-ion with heat resistantand salt resistant properties are mainly applied to tertiary recovery in an oilfield.When every metric ton of macromolecule polyacrylamide products are injectedinto the oil reservoir, additional 100 - 150 metric tons of crude oil can be produced.In respect of water treatment, they can be used as flocculating agent and sludgedehydrant. In the textile and printing and dyeing industries, they can be usedas sizing agent and colorant; while in the paper-making industry, they can beused as retention aid, filter aid and paper intensifier for the dryness and wetness;In sugar-refining industry, they can speed up the settlement of fibril inthe cane juice and improve the quality of sugar.
