Polyacrylamide, as a kind of flocculant, is widely used in municipal wastewater treatment and industrial wastewater treatment. Increasingly stringent regulations to promote the development of water treatment industry, the field of municipal sewage treatment has not been affected by the financial crisis, but showed a good growth momentum. At the same time, in the municipal water supply system, more and more technical requirements for customized solutions, which also increase the additional profit margins for the product. In addition, North Africa, including Morocco, Tunisia, Algeria and Egypt, and other countries, including the new municipal sewage treatment market, while some other countries, such as Saudi Arabia and Qatar, is also increasing the water treatment of private investment. This case also have the opportunity to Suez, Veolia Water treatment products sales of Service Corporation. In industrial wastewater treatment, coal mining and thermal power station to provide a lot of business space.

To use more attention technology of reclaimed water is also a market driven. In the field of water treatment, the challenge of polyacrylamide market is mainly from industrial wastewater treatment. Industrial wastewater treatment is often mature and self-contained, which limits the development of the market. As the recession has led to a large number of factories closed down, the amount of waste water treatment has been greatly reduced, while many other companies to save money, only to carry out a minimum of waste water treatment. In addition, the decline in oil production, mining and paper industry will also affect the development of water treatment chemicals industry market economy.

Polyacrylamide flocculation principle PAM for flocculation, and surface properties of flocculation species, especially the zeta potential, viscosity, turbidity and suspended liquid pH value relevant and particles on the surface of the potentiodynamic, join surface charge instead of PAM particle polymerization of reason, can quick action potential decreased and cohesion.

Adsorption bridging: PAM molecular chain fixed on different particles on the surface, the polymer is formed between the particles of the bridge, the particles form aggregates and settlement.

Surface adsorption: adsorption of polar groups on the molecular polyacrylamide particles PAM.

Enhancement effect: PAM molecular chain and the dispersed phase through all sorts of mechanical, physical, chemical effect, will be scattered implicated together and form a mesh, thus enhanced role.

Polyacrylamide manufacturer specialized in the production of (anionic, cationic, nonionic polyacrylamide (PAM), high purity, good solubility, high molecular weight, the production company of nonionic polyacrylamide is a polymer with acrylamide were made. Anionic polyacrylamide produced by the production of polyacrylamide is divided into two kinds of production processes, one is poly (acrylamide and acrylic acid),

(Note: PAM is divided into: polyacrylamide, anionic polyacrylamide, cationic polyacrylamide. Two gender polyacrylamide, nonionic polyacrylamide. Polyacrylamide is a kind of water soluble linear polymer material, which is formed by the polymerization of acrylamide. The chemical properties of single body are very active, and a series of chemical reactions can be carried out at the double bond and amide group. The products of different molecular weight and charge can be obtained by using different processes. The average molecular weight of PAM is a number of functional groups from thousands to millions more than the key molecules, and most of the water can be ionized. According to the characteristics of the dissociation groups, the characteristics of the anion type (such as --NH3OH, --SO3H, --OSO3H, --COOH, -CONH3OH) and nonionic. Product appearance is white powder, soluble in water, almost insoluble in benzene, ether, ester, acetone and other general organic solvents, its water solution is almost transparent viscous liquid, non-toxic, non corrosive, solid PAM has a moisture absorption, moisture absorption increased with the increase of ionic degrees, PAM thermal stability is good, but at 150 degrees above the easy decomposition of nitrogen, the density (g) 1.302. The non Newtonian flow of PAM was demonstrated by the stress of the glass at 153.

    Nonionic polyacrylamide is mainly used as a flocculant, because of its molecular chain containing a certain amount of polar gene can be adsorbed on the suspended solid particles, so that the formation of large particles between the particles. It accelerates the deposition of particles in the suspension, has a very clear acceleration of the solution to the clarification, promote the filtration and other effects, non ion polyacrylamide in the chemical industrial wastewater, wastewater treatment, municipal wastewater treatment. Especially when the sewage is acidic, the use of this product is the most appropriate. Can be used in conjunction with inorganic flocculant, poly iron, aluminum and other inorganic salt. For petroleum industry, oil production, drilling mud, waste mud treatment, prevent water channeling, reduce friction, improve oil recovery rate, the three oil recovery has been widely used. Non ionic polyacrylamide in other industries, the food industry for cane sugar, beet sugar production in sugar cane juice and syrup phosphorus float extraction. Enzyme preparation fermentation liquid flocculation clarification industry, also for the recovery of protein feed, good performance, stable quality, recovery of the protein powder on chicken survival rate increased with increasing weight, no adverse effect on egg production, synthetic resin coating, construction material for grouting and blocking water, building adhesive industry, building materials industry, improve the quality of cement, caulking repairplugging agent, soil improvement, electroplating industry, printing and dyeing industry. Nonionic polyacrylamide in textile sizing agent and the stability of the slurry performance, little mortar, fabric breakage rate low, clean cloth, followed by non ion polyacrylamide is mainly used as flocculant.

    Nonionic polyacrylamide is water-soluble polymer or polymer electrolyte. Because of the existence of a certain amount of polar groups in the molecular chain, it can through the adsorption of suspended solid particles, the bridge between particles or through the charge and the particles coalesce to form large flocs. Therefore, it can accelerate the settlement of particles in the suspension, has a very clear speed up the solution to clarify, promote the effect of filtering and so on. Mainly used for various industrial wastewater flocculation sedimentation, precipitation clarification processing. Such as pulp and paper pulp and waste water treatment, mineral processing and metal smelting process of wastewater treatment, iron and steel plant and stone processing plant of wastewater treatment, etc.. Due to the non ion polyacrylamide is a polymer or polymer electrolyte and its molecular chain containing a certain amount of polarity genes to adsorption of solid particles suspended in the water, make the bridge between particles of large flocs formed. It accelerates the settlement of particles in the suspension, has a very clear acceleration of the solution to clarify, promote the effect of filtering and so on.
