Applications
Oil Industry
Polyacrylamide is widely used in oil extraction for profile control, water shut-off, drilling fluids, and fracturing fluids. It plays a crucial role in drilling for reducing filtration loss, flocculation, shale inhibition, dilution, plugging leaks, cooling and lubricating drill bits and drill strings, carrying cuttings, and cementing.
Water Treatment Industry
The amide groups of polyacrylamide can form hydrogen bonds with many substances through affinity and adsorption. Relatively high molecular weight polyacrylamide can form bridges between adsorbed ions, generating flocs and accelerating particle sedimentation.
Coal Washing Industry
PAM can promote the rapid settling of coal slime, clarify the coal slime water, improve the coal recovery rate, and enable the recycling of water resources.
Incense Making Industry
PAM has good thickening properties, and its finished incense has the characteristics of good folding resistance, strong flexibility, no softening, good burning, no special odor, and low ash content. After use, it increases the shape of the incense stick and ensures the quality of its later use.
Mineral Processing Industry
PAM is used to remove or reduce harmful impurities to obtain raw materials needed for smelting or other industries. It is effective in slag flocculation, dewatering, and wastewater recycling.
Textile Industry
PAM, as a textile auxiliary agent, can be used as a textile coating sizing agent. After sizing, it can reduce short ends and shedding on the loom and enhance the antistatic properties of textiles.
Paper Industry
PAM can improve the retention rate of fillers and dyes, thereby reducing the loss of raw materials and environmental pollution. It can also improve the dry and wet strength of paper and, as a dispersant, increase the adhesion of pigments in paper coatings. It is also used in wastewater treatment in the paper industry.
Sugar Industry
In the sugar industry, PAM is used to accelerate the sedimentation of sugar juice and the clarification of sugar solution.
