Sinofloc has developed a wide range of polymers , both in dry powder and liquid emulsion forms, to cover the vast majority of existing conditions within the various industries (water treatment, mining processing, oil & gas etc.). Sinofloc polyacrylamides range from cationic to non-ionic and anionic in nature, and the selection of the best product depends on several parameters. General guidelines regarding typical product selection for a given application used in a specific industrial can be found on the individual product technical data sheets, as well as in the sections regarding the industries we serve. However these are not to be taken literally. In order to select the optimum product for a specific application, it is essential that laboratory testwork followed by plant trials are carried out. Initial laboratory testwork will give an indication of the best product and approximate dosage, which will then need to be confirmed with more accuracy by running plant trials...

The major mineral processing industries we supply our products to are as follows:  Coal Gold/Silver Copper Lead/Zinc Alumina Uranium  Iron/Steel Titanium Dioxide Nickel Phosphates Potassium Manganese Sodium Vanadium Oil Sand  In most mineral processes where there is a flocculant requirement for a either sedimentation or centrifugation application then a high molecular weight product is desired. The anionic product range offers ultra high molecular weight products ensuring maximum performance and cost efficiency for sedimentation and centrifugation applications.  The extensive product range of flocculants and coagulants includes a wide range of anionic /cationic charged products, all at varying molecular weights, so that all applications in the mineral processing industry are catered for.  Apart what we illustrated in Polyacrylamide for Mineral ProcessingⅠ,Summaries of the major mineral processing industries we supply our products to are as follows:  ...

The viscosity of polyacrylamide aqueous solution is influenced by the solution viscosity, ph value, shear rate and the relative molecular polymer.  Polyacrylamide solution viscosity and concentration are similar to the logarithmic relationship. High molecular weight polyacrylamide concentration is difficult to deal with when the concentration is over 8%. Increasing the temperature could decrease the viscosity, but the effect is not significant. The viscosity of nonionic polyacrylamide solution is not affected by the pH value. However, when the PH value is over 9, the viscosity of polyacrylamide is quickly increased due to hydrolysis. At this time, the impact of PH value was revealed. Pure polyacrylamide is easy to hydrolyze. In the aqueous solution, when the PH value from acid to alkaline range, the non-ionic amide to anionic carboxyl, carboxyl negatively charged and produce repulsion, resulting in macromolecule stiffness, increasing the friction between molecules, viscosity and th...

The residual monomer content of polyacrylamide is a critical data to measure whether it is suitable for the food industry. Polyacrylamide polymers are non-toxic which have been widely used in the international water purification, food industry, and sugar industry. However, in the industrial polyacrylamide, it is inevitable that there are trace amounts of unpolymerized acrylamide monomer, which has some toxicity.  Therefore, it is necessary to strictly control the residual monomer content in polyacrylamide products. International requirements for drinking water and food industry in the polyacrylamide in the residual monomer content are less than 500ppm.  The anionic degree of polyacrylamide has a great effect on its use, but its suitable value depends on the kind and nature of the material being treated, and there will be different optimum values in different cases. SINOFLOC polyacrylamide (medium charge, high MW) used in the sugar industry can be used for different materi...

Sinofloc series polyacrylamide is used in wastewater treatment with anion and cationic type, which can be used in flocculation precipitation and sewage treatment. Generally speaking, the higher the ion degree is, the more compact the sludge formation will be. Our anionic products can be used for flocculation and precipitate the suspended solids in sewage. Our cationic products are generally used in sludge treatment press, which will not clog the filter cloth, and the formation of sludge is more compact. Sludge is the main content of urban sewage and is a serious pollution source. Our technical staff will help customers test the nature, composition and solid content of the sludge and select the best products for this application. In general, cationic polyacrylamide  is used for the treatment of organic sludge, anionic polyacrylamide is for inorganic sludge. It is not suitable to use cationic polyacrylamide when it is very alkaline, but it is not suitable to use anion polyacr...
