Polyacrylamide amide :

Polyacrylamide (PAM) is a general term for acrylamide homopolymer or copolymer with other monomers. It is one of the most widely used water-soluble polymers. Because of polyacrylamide units contain amide group in structure, easy to form hydrogen bonding, make it has good water solubility and high chemical activity, easily obtained by grafting and crosslinking branched chain or a variety of modification of the reticular structure, in oil drilling, water treatment, textile, papermaking, ore dressing, has extensive applications in medicine, agriculture and other industries, have "all sectors additives". The main application fields abroad are water treatment, paper making, mining, metallurgy, etc. At present, the largest domestic consumption is in the field of oil extraction, the fastest increasing consumption is in the field of water treatment and paper making.

Application field

Water treatment field

Water treatment includes raw water treatment, sewage treatment and industrial water treatment. In raw water treatment with activated carbon and other use, can be used for the condensation of suspended particles in living water, clarification.

Application in oil recovery

Polyacrylamide is a kind of multi-functional oil field chemical treatment agent, widely used in the process of drilling, cementing, completion, workover, fracturing, acidification, water injection, water shutoff profile control, three oil recovery operations, especially in the field of drilling, water shutoff profile control and three oil recovery.

Paper making field

Polyacrylamide is widely used in the field of papermaking as retention aid, filter aid, homogenizing agent to improve the quality of paper, slurry dehydration performance, retention rate of small fibers and fillers, reduce raw material consumption and environmental pollution, used as dispersant, can improve the uniformity of paper.

The medicinal materials

Polyacrylamide gELS CAN BE USED AS non-thromBIN PROGRANULATING AGENTS, SURGICAL MATERIALS, CONTACT LENS MATERIALS, the outer coating of microcapsules, and for the manufacture of high quality hemostatic tethers, women's sanitary napkins and children's diapers.

Other industries

In the food industry, used for sugarcane sugar, beet sugar production of sugarcane juice clarification and syrup phosphorus float extraction. Enzyme preparation fermented liquid flocculation clarifying industry, also used in feed protein recovery, stable quality, good performance, recovery of protein powder to chickens and raising the survival rate of weight gain, no adverse effects of egg production, synthetic resin coating, civil water plugging grouting materials, building materials industry, improve the quality of cement, construction adhesive, caulking repair and plugging agent, soil improvement, electroplating industry, printing and dyeing, etc.
