1. Water treatment

The applications of polyacrylamide in the water treatment industry mainly include raw water treatment, sewage treatment and industrial water treatment.In raw water treatment, polyacrylamide and activated carbon can be used for coagulation and clarification of suspended particles in living water. Using organic flocculant polyacrylamide instead of inorganic flocculant, even if the sedimentation tank is not modified, the water purification capacity can be increased by more than 20%. Polyacrylamide can be used for sludge dewatering. In industrial water treatment, polyacrylamide is mainly used as a formulation.

2. In the field of oil production, in oil production, polyacrylamide is mainly used for drilling mud materials and improving oil recovery. It is widely used in drilling, well completion, cementing, fracturing, and enhanced oil recovery operations. In order to improve oil recovery, polymer flooding and ternary combined flooding technologies are currently being promoted. By injecting an aqueous polyacrylamide solution, the oil-water flow rate ratio is increased, and the crude oil content in the produced material is increased.

3. The field of papermaking.

Polyacrylamide is widely used as a resident agent, filter aid, and leveling agent in the papermaking field. Its function is to improve the quality of paper, improve the dehydration performance of the slurry, increase the retention rate of fine fibers and fillers, and reduce the consumption of raw materials and environmental pollution.

4.The field of textile printing and dyeing

In the textile industry, polyacrylamide is used as a sizing agent and finishing agent for fabric post-processing, which can produce a soft, anti-wrinkle, and anti-mildew protective layer. Utilizing its strong hygroscopicity, it can reduce the yarn breakage rate during spinning; polyacrylamide can be used as a post-treatment agent to prevent fabric from being statically flame-retardant; when polyacrylamide is used as a printing and dyeing additive, it can make the product have high adhesion and brightness High, can also be used as bleaching non-silicon polymer stabilizer;

5. Mining, coal washing and other fields

In the fields of mining and coal washing, polyacrylamide can be used as a flocculant to promote mining. Coal washing can recover the sedimentation of solid matter in the water, clarify the water, recover useful solid particles, and avoid environmental pollution;

6. The field of medicine

Polyacrylamide can be used as a flocculant for separating antibiotics in the pharmaceutical industry. Used as an excipient binder for tablets and process water clarifiers, etc.;

7. Building materials

Polyacrylamide can enhance the hardness of gypsum cement and accelerate the dehydration of asbestos cement.

In addition to the above seven mainstream applications, polyacrylamide is also widely used in urban and rural areas.

Shandong Welldone, as one of the top ten manufacturers of polyacrylamide in China, can provide customers with the required anionic, cationic and non-ionic polyacrylamide. If you are interested in a certain product, please contact us.
