Cationic polyacrylamide Polymers organic chemicals PAM. Polyacrylamide, abbr. PAM. This product is a water- soluble high polymer.It’s not soluble in most organic solvents, with good flocculating activity, and can reduce the friction resistance between liquid.It is widely used in many fileds like Water Treatment, Oil Exploration, Sludge Dewatering, Paper Making, Textile, Sugar Making, Coal
The Polyacrylamide is one of the earliest and the widest used additives in pape rmaking industry, it is even called as “the pape rmaking additive”.. The polyacrylamide as the additive in the pap ermaking industry mainly has the following applications: 1. The polyacrylamide working as the retention agent can achieve the below effects:
For example, use the fatty acid sizing agent 0.5, the PAM type paper strengthening agent 0.2, the aluminum sulfate 1.0 and the epoxy reinforced agent 0.7, add them into the paper making chemical pulp, make the paper product soaked in 200C for one hour, the tearing strength of the paper product can reach up to 183g, and with the good printing
The most common question is, how much polyacrylamide does a ton of water use? At present, polyacrylamide is commonly used as flocculant in water treatment field, or as thickener and binder in industrial field. When used as flocculant for water treatment, the concentration of polyacrylamide is generally from 1/1000 to 3/1000.

Polyacrylamide, an acrylic resin that has the unique property of being soluble in water. It is employed in the treatment of industrial and municipal wastewater. Polyacrylamides are produced by the polymerization of acrylamide (C 3 H 5 NO), a compound obtained by the hydration of acrylonitrile. Acrylamide is usually dissolved in water; it has toxic effects on the nervous system and must be
The reason is when more than a certain concentration, polyacrylamide can not only have flocculation effect, but from the dispersion and stabilizing effect. In the choice of polyacrylamide models, following factors could be considered: 1, sludge is the inevitable product of sewage treatment.
Polyacrylamide is also used in water, sewage and waste treatment, oil recovery, ore processing paper making, and to make permanent-press fabrics, to synthesize dyes, contact lenses, and in the construction of dams, tunnels and sewers (Habermann 2002).  Polyacrylamide is also present in cigarette smoke.
The wastewater has about 8,000 tons of suspended matter. If the wastewater is not treated timely and effectively, it will not only waste a large amount of water resources to pollute the water quality but also affect the normal production and life of nearby residents. Sand washing wastewater treatment is actually the separation of mud water. The
COMMERCIAL Polyacrylamides Major manufacturers of acrylamide polymers are BASF, SNF Floerger, Shangdong Tongli , and Kemira. Applications. Poly(acrylamide-co-acrylic acid) and its sodium salts (APAM) are widely used as thickening agent, binder, super absorbent, soil conditioner, filtering aid, flocculating agent, crosslinker, suspending agent, lubricant, and oil recovery agent.
In both tap water and river area where polyacrylamide ware used for the treatment of potable tap water, acrylamide was detected at levels of less than 5µg/L. In West Virginia (USA), acrylamide was reported to contain 0.024 – 0.041 mg/L in the sample collected from public drinking water supply (Brown and Rhead, 1979).
A considerable amount of information has been reported on how various polymeric additives affect drainage rate and fines retention. When used as a drainage aid, polyacrylamide can overcome slow drainage of fiber furnishes containing high-yield pulps such as stone groundwood, hardwood pulps and recycled fiber furnishes.
CHEMICALS USED IN PULP &PAPER MANUFACTURING AND COATING. While there are about 3000 or so different types of chemicals which "can be used" in papermaking, in practice only about 200 individual chemicals are typically used, each satisfying a specific need.
Thomas L. Staples, Pronoy K. Chatterjee, in Textile Science and Technology, 2002. 3.2.1 Polyacrylamides. Polyacrylamides are widely used in an uncrosslinked form as thickeners and flocculants in the oil industry, ore recovery, water and sewerage treatment, and a variety of industrial and consumer products .Crosslinked polyacrylamides, particularly when partially hydrolyzed to yield acrylic
U.S. patent 3,631,104 (1971) C. E. Habermann, B. A. Terfertiller (Dow Chemical) Polymerization of polyacrylamide. If heated above the melting point, acrylamide may polymerize. Caution, the reaction is exothermic. Acrylamide may be polymerized in water at concentrations from 8- 20%, using AIBN, peroxide, or redox catalysts.
Water Purifying Chemicals. Trichloroisocyanuric Acid (TCCA)How to use the polyacrylamide products in water treatment. 2014-01-15.When used, the first two agents dubbed lime and 5-10 % polyacrylamide solution of 1 ‰ ; then add lime slurry and stir , then add the final solution of polyacrylamide paste and stir.
The global polyacrylamide market size is expected to reach USD 6.8 billion by 2025, expanding at a CAGR of 6.2% over the forecast period, according to a new report by Grand View Research, Inc. Increasing penetration of the product in water purification activities as a flocculating agent is expected to propel the demand for polyacrylamide
Emulsion type of drag reduction agent. are completely hydrolyzed in water, which improve chaotic fluid way, thus reducing the pumping pressure, to achieve the objective of the given velocity. For water-based fluid, effectively drag reduction can enhance the guar gum fracturing system viscosity, and increase shale gas fracturing adaptability.
1. WATER-SOLUBLE POLYACRYLAMIDE 1.1. Uses of polyacrylamide Polyacrylamide [p(AM)] is one of the most widely used materials as a ‘ occulant. It ” nds wide applications in many ” elds, e.g. municipal water treatment [1– 3], sewage treatment [4– 19], reverse osmosis membranes , mineral processing
