The main applications of polyacrylamide(PAM,FLOCCULANT)

The polyacrylamide market in 2017-2020

Based on product type, the report categorizes the global polyacrylamide market into the following segments:


  •                                 Anionic polyacrylamide


  •                                 Cationic polyacrylamide


  •                                 Non-ionic polyacrylamide

Anionic polyacrylamide

“Anionic polyacrylamides carry a negative charge, which makes them a suitable option to pick positively charged particles such as clay and sand. They are mainly used in dust control, crop dusting, furrow irrigation, hydro-seeding,construction projects, landscaping, and mining applications. Anionic polyacrylamide compounds show no aquatic toxicity, which makes them safe for use in soil and water conservation,” says Ajay Adikari, one of the lead analysts at Technavio for plastics, polymers and elastomers research.

Anionic polyacrylamides are also used in mining and metallurgy applications, where they promote solid-liquid separation and reduce environmental pollution and the overall production cost. In the coal industry, anionic polyacrylamides are used as flocculants and coagulants to improve the separation of coal from impurities. Additionally, these compounds are also used as thickening agents in the petroleum, cosmetics, and paper and textile pulp industries, and the paper industry where they are used as retention aids and dry strength agents. These applications will significantly drive the market in the forecast period.

Cationic polyacrylamide

Cationic polyacrylamides carry a positive charge and can attract and bind to negatively charged particles such as organic waste materials. This makes them suitable to be used in animal waste treatment, wastewater plants, and purification of drinking water. It also finds applications in mining and paper processing industries. Since these compounds are hydrophilic in nature, they are soluble in water but not soluble in organic solvents, which makes them suitable for use in breweries and alcohol, sugar, monosodium glutamate, and meat manufacturing companies.

Cationic polyacrylamide is also used in the paper industry as an additive to aid in retention and enhances the strength of the paper. It also works as an effective dispersant in paper production. It also finds application in the treatment of textile printing and dyeing wastewater due to the presence of negatively charged particles in this wastewater.

Non-ionic polyacrylamide

“Non-ionic polyacrylamides are high molecular weight polymer compounds with low ion exponent. These non-ionic compounds are hydrophilic in nature and thus can effortlessly dissolve in water. They are commonly used in flocculation, thickening, film forming, dispersal, bonding, and stabilizing. These polyacrylamides are predominantly used in the treatment of wastewater, municipal sewage, and mineral ore processing,” says Ajay.

In coal washing, non-ionic polyacrylamide compounds are used in the separation of coal and sedimentation of coal dust and coal slurry. These compounds help enhance recovery rates of coal dust particles and improve the filtration rate. Also, since it is safe on aquatic flora and fauna, it can be used in the treatment of acidic wastewater and sewage. The applications in these industries will drive market segment through the forecast period.

Analysis of Water Side Corrosion of High Pressure Boiler

  1. Summary

After the pretreatment and ion exchange process, suspended solids, colloids, and dissolved salts in the water supply of high pressure boilers have been removed, but a small amount of oxygen and carbon dioxide dissolved in water can cause the corrosion of the boiler water supply system.


  1. Reasons for water side corrosion of high pressure boiler

2.1 Dissolved oxygen corrosion

Dissolved oxygen corrosion is a kind of electrochemical corrosion, iron and oxygen as the two electrodes, which form a corrosion cell. There are two reasons for it. On one hand, iron oxide cap produces an acid solution, accelerating the dissolution of iron; on the other hand producing iron oxide cap, the corrosion products prevents the proliferation of oxygen. In the corrosion products formed under the anode area of oxygen, the external will form a rich oxygen cathode area, thus, a concentration difference cell is formed. The two part of the differences accelerates the corrosion reaction. With the increase of the amount of dissolved oxygen in water and the water temperature, the corrosion becomes stronger.

2.2 Sediment corrosion

Under normal operating conditions, the pH value is kept between 9-11,at this time, a dense Fe2O3 protective film is formed on the metal surface, So there is no serious corrosion. However, when the existence of sediment on boiler heating surface, the temperature rise of the metal pipe wall under the sediment due to the bad heating surface, and the water evaporation of the sediment, it will produce corrosion under sediment. From the boiler equipment inspection, scale, salt accumulation of the shape, color, composition analysis, corrosion status analysis, prone to corrosion of deposition site is the main drum, two stage superheater, low temperature reheater.

2.3 Sour corrosion

In acidic water,iron reacts with acid to produce iron ions and releases hydrogen,meanwhile hydrogen atoms react with carbon steel to produce the CH4. Decarburization will make metal cracks along the grain boundary. When Boiler pressure in 3.5MPa, hydrogen ions can quickly diffuse into the metal and cause the metal to become brittle and damaged. CO2 and steam flows through saturated steam and superheater pipe, steam turbine, then a part of the air pump is taken away, and the other part is integrated into the water, Formatting H2CO3 weak acid. H2CO3 partially decomposed to produce H+ and cause corrosion. When the surface water is used as the water source for the boiler,it can produce inorganic acid corrosion.The cooling water into the boiler, the pH value will decline and format the acid corrosion. Especially in the treatment of volatile water, corrosion will be more serious.

2.4 Alkaline corrosion

Free alkali can be concentrated between porous sediments and metal surfaces of furnace tubes, Excessive concentration of alkali dissolved metal protective film and the formation of a mixture of Ferrous iron acid radical and acid radical ion. This kind of alkali corrosion is especially easy to occur in the place where the heat is larger and have the sediment. Carbon steel and water contact surface pH value in the 8.5-10.3, the general it will not occur alkaline corrosion.

2.5 Impact corrosion

① In the condensed water pipe, steam mixed flow velocity changes and wash wall, cause scour wall thinning and rupture.

② The flow velocity is high, the flow is turbulent and the local position of the turbulence zone is formed continuously.

③ The deaerator position is too low, high temperature water through the pump will instantly vaporize, and bubbles will produce cavitation pits in water pump.

Die Casting VS Other Process


Die casting produces parts with thinner walls, closer dimensional limits and smoother surfaces. Production is faster and laor costs per casting are lower. Finishing costs are also less.

Die casting VS permanent mold

Die casting offers the same advantages versus permanent molding as it does campared with sand casting.

Die casting VS forging

Die casitng produces more complex shapes with closer tolerances, thinner walls and lower finishing costs. Cast coring holes are not available with forging.

Die casting VS stamping

Die casting produces complex shapes with variations possible in section thickness. One casting may replace several stampings, resulting in reduced assembly time.

Die casting vs. screw machine products – Die casting produces shapes that are difficult or impossible from bar or tubular stock, while maintaining tolerances without tooling adjustments. Die casting requires fewer operations and reduces waste and scrap.
