Amphoteric polyacrylamide also called zwitterionic polyacrylamide or dipolar ionic polyacrylamide. The molecular chain of the amphoteric flocculant has two or more functional groups, of which have at least one anionic charge and one cationic charge. Unlike other mono-ionic polyacrylamides that only form either a cationic or anionic charges, the amphoteric polyacrylamide simultaneously have both ionic states.

Demystifying the Contrasts: Decoding Cationic Polyacrylamide and Anionic Polyacrylamide Differences in Water Treatment. Explore their Variances Now!

From the appearance, there is almost no difference. They are white particles or powdery solids. They can only be distinguished through small experiments! 1. Application of cationic polyacrylamide (1) Sludge dewatering According to the nature of sludge, the corresponding types of this product can be selected, which can effectively dewater the sludge by gravity before the sludge enters the pressure filtration. During dehydration, it produces large flocs, does not stick to the filter cloth, does not flow away during pressure filtration, uses less, has high dehydration efficiency, and the moisture content of mud cake is less than 80%. (2) Treatment of sewage and organic wastewater Cationic polyacrylamide shows positive electricity in acidic or alkaline media, so it is very effective to flocculate, precipitate and clarify the sewage with negative charge of suspended particles in the sewage, such as wastewater of alcohol factory, brewery, monosodium glutamate factory, sugar factory, meat food factory, beverage factory, textile printing and dyeing factory, etc. The effect of cationic polyacrylamide is several times or tens of times higher than that of anionic, non-ionic polyacrylamide or inorganic salt, because this kind of wastewater generally has negative charge.

Polyacrylamide emulsion is prepared by dispersion or inverse emulsion polymerization, which is a form of polyacrylamide liquid present. Besides the characteristics of solid polyacrylamide flocculants, through the molecular chain of polar groups to adsorb suspended solids in the water particles, the emulsion could formats the large flocs through bridge between the particles or electricity.

SINOFLOC is offering a broad range of leading-class friction reducer to our customers from fresh water to heavy brines. Our product range includes anionic polyacrylamide powder, anionic polyacrylamide emulsion and cationic polyacrylamide powder, which have been approved excellent performance in the conditions with high TDS levels and API brine.

Nonionic Flocculants SINOFLOC nonionic flocculants are technically pure polyacrylamides. Nonionic polyacrylamide exhibits neutral nonionic properties in the aqueous solution which is hardly influenced by the PH value in the application. SINOFLOC nonionic flocculants are suitable for use as a settlement aid in many different mineral-processing applications and are particularly effective under very low PH conditions, as encountered in acidic leach operations.

1. Solubility of anionic polyacrylamideAnionic polyacrylamide is easily soluble in cold water, and the relative molecular weight has little effect on its insolubility. However, when the concentratio

Sinofloc polyacrylamide flocculants has good performance in thickening, flocculation, and fluid rheology modifiers, which is widely used in drilling, plugging, water acidification, fracturing, wash well, completion, drag reduction, scale and drive oil. Currently many oil fields have entered the field of secondary, tertiary recovery, reservoir depth of 1000m above generally in some reservoir depth of 7000m

SINOFLOC amphoteric flocculants are partially hydrolyzed polyacrylamide with high molecular weight. This amphoteric polyacrylamide is easily to remove both the positive and negative charged contents particles in a suspension solution.

SINOFLOC tailor-made products are designed to be used as the concrete additives, cement additives, grouts, adhesives, coatings, and concrete additives for waterproofing in the construction industry. Our supply package includes polyacrylamide, superabsorbent, sodium polyacrylate.

SINOFLOC offer a wide range of powder cationic polyacrylamide, as well as coagulants, to be used on paper mills and wastewater treatment plant. Our polymers are suitable for the functions of different types of paper production:

SINOFLOC nonionic flocculants are high and very high molecular weight nonionic polyacrylamide polymers, in dry powder character. Our products have been specially designed for the industrial wastewater treatment process including paper, textile, and food industry and produced water from the oil industry, especially for the water with lower PH 1-3.

Anionic Flocculants SINOFLOC anionic flocculants are co-polymers of acrylamide with increasing proportions of acrylate groups, which give the polymers negative charges, and thus anionic active character, in aqueous solution.

The solutions of SINOFLOC anionic polymers must be prepared in suitable plants equipped with dry powder feeding and dispersion units and with continuous and moderate agitation. The dissolution water must have a temperature included between 10°C and 40°C; For a correct use of SINOFLOC anionic polyelectrolyte and in order to achieve the best possible results, it is necessary to allow a "maturation" time of 60 minutes. When treating turbid water, the flocculants solution must be added to the water in a point of average turbulence, in order to achieve a thorough and homogeneous mixing without impairing the flock formation. Recommend operating concentration of anionic powder polyacrylamide polymer is 3g/l, and the maximum operating concentration is 15g/l.
