Polyacrylamide (PAM) is a general term for polymers obtained by copolymerization of acrylamide homopolymers or other monomers. It is one of the most widely used varieties of water-soluble polymers. Since the structural unit of polyacrylamide contains amide groups and is easy to form hydrogen bonds, it has good water solubility and high chemical activity. It is easy to obtain a variety of modified products with branched or network structures through grafting or cross-linking. It has a wide range of applications in oil extraction, water treatment, textiles, papermaking, mineral processing, medicine, agriculture and other industries, and is known as the “auxiliary agent for all industries”. The main application areas abroad are water treatment, papermaking, mining, metallurgy, etc.; the largest amount of domestic use is currently in the oil extraction field, and the fastest growing use is in the water treatment field and papermaking field.
2, Application:
Application in water treatment:
Polyacrylamide is used in combination with activated carbon in raw water treatment, and can be used for the coagulation and clarification of suspended particles in domestic water. Using organic flocculant acrylamide instead of inorganic flocculant can increase the water purification capacity by more than 20% even without modifying the sedimentation tank; in sewage treatment, the use of polyacrylamide can increase the utilization rate of water reuse circulation, and can also be used for sludge dehydration; it is used as an important formula agent in industrial water treatment.
Application in mines:
In the mining process, a large amount of water is usually used. It is usually necessary to recover useful solids from the water and purify the wastewater for reuse. The application of PAM flocculant can promote the sedimentation of flocs, clarify liquids, and remove water cakes, thereby improving production efficiency, reducing tailings losses and water consumption, reducing equipment investment and treatment costs, and avoiding environmental pollution.
Application in oil production
Polyacrylamide aqueous solution has a high viscosity, and has good thickening, flocculation and rheological regulation effects. Widely used in the drilling, cementing, completion, well repair, fracturing, acidification, water injection, water plugging and profile control, and tertiary oil recovery operations of oil production, especially in the fields of drilling, water plugging and profile control, and tertiary oil recovery.
Papermaking field
In the papermaking field, polyacrylamide is widely used as a retention agent, filter aid, uniformity agent, etc. to improve the quality of paper, slurry dehydration performance, retention rate of fine fibers and fillers, reduce raw material consumption and environmental pollution, and as a dispersant, it can improve the uniformity of paper.
Other industries
(1) Food industry, used for cane juice clarification and syrup phosphorus flotation extraction in the production of cane sugar and beet sugar.
(2) Enzyme preparation fermentation liquid flocculation clarification industry, also used for feed protein recovery, stable quality, good performance, the recovered protein powder has no adverse effects on the survival rate, weight gain and egg production of chickens.
(3) Synthetic resin coatings, civil engineering grouting material water plugging, building materials industry, improve cement quality, construction industry adhesives, caulking repair and water plugging agents.
3, Specification:
1) Cationic Polyacrylamide
Cationic PAM, copolymerized by cationic monomer and acrylamide, is a water water-soluble and linear organic polymer with high molecular weight.
2) Anionic Polyacrylamide
Anionic PAM, copolymerized by acrylamide and acrylate monomer, is a ultrahigh molecular weight polymer. It has great adsorptionadsorption-bridge effect. Different model can be used according to the different application and the requirement of clients for the products performance.
3) Nonionic Polyacrylamide
Nonionic polyacrylamide is homopolymer formed of acrylamide with high pu rity, good solubility and high molecular weight. This series of products are with high molecular weight polymer and liner polymer low ion degree, Because of its special groups, and endow it with focculation and dispersion, thickening and bonding, film, gel, stab le colloidal.
