Anionic polyacrylamide (APAM) Product Description: the appearance of anionic polyacrylamide (APAM) is white powder, with molecular weight ranging from 6 million to 25 million. It has good water solubility, can be dissolved in water in any proportion and insoluble in organic solvents. The pH range is 7 to 14, which is characterized by high polymer electrolytes in neutral alkaline medium, sensitive to salt electrolytes, and crosslinked with high valence metal ions to form insoluble gel.

　　Anionic PAM

　　Industrial wastewater treatment: for suspended particles, higher concentration, particles with positive charge, the pH value of water is neutral or alkaline sewage, steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other sewage treatment, the effect is the best. Drinking water treatment: the water source of many Waterworks in China comes from rivers, with high content of sediment and minerals, which is relatively turbid. Although it has been precipitated and filtered, it still can not meet the requirements. It needs to add flocculant, the dosage is 1 / 50 of inorganic flocculant, but the effect is several times that of inorganic flocculant. Inorganic flocculant and cationic polyacrylamide can be used for river water with serious organic pollution The effect is better when used together. At present, anionic polyacrylamide is added to flocculate and precipitate starch particles, and then the precipitate is pressed into cake shape by filter press, which can be used as feed. The alcohol in alcohol factory can also be dehydrated by anionic polyacrylamide and recovered by pressure filtration. It is used for mud settlement of river water. It is used as dry strength agent for paper making.

　　It is used for paper-making auxiliaries and rate AIDS. Adding a small amount of pam-lb-3 anionic polyacrylamide into the pump mouth type pulp storage tank before papermaking can increase the retention of fillers and fine fibers on the net by 20-30%. 20-30kg pulp can be saved per ton.

　　For example: in the process of coal washing, a large amount of waste water is produced and directly discharged to pollute the environment. It must be cleaned up and recycled. The recovery of coal slime in the water is also very valuable. However, it takes time and effort to rely on natural settlement, and the water is not clear.

　　In addition, the application of anionic polyacrylamide in fragrance industry is becoming more and more popular. The characteristics of anionic polyacrylamide products are: good solubility, high viscosity, strong toughness, flammability, no smoke, no peculiar smell and no toxicity; The product performance is stable, which avoids the uneven bonding quality of other vegetable gum powder and common starch due to different places of origin and time. The formula needs to be adjusted repeatedly in the production of fragrance industry, so as to avoid the phenomenon of unstable product quality; the appearance of fragrant products is smooth, smooth, well formed and not easy to be broken; In particular, the cold water gelatinization, no need to boil paste, the material can be directly mixed evenly, water mixing can be produced, and the material mixed with water will not be hard to use after a long time of storage, which effectively saves energy and facilitates production operation.

　　Application effect: the incense products made of this product have smooth appearance, no fracture, no mildew, strong folding resistance, good color, no fading after drying, sufficient ignition time, good flammability, and no "broken end" flameout of the iron toothed disc, which is conducive to the improvement of the volatile rate of the effective components of mosquito repellent incense and reduce the loss of finished products in the drying process, and at the same time, it can greatly reduce the loss of workers Labor intensity, improve work efficiency. In addition, the product has no pollution to the environment and can meet the requirements of green environmental protection.

　　Economic benefits: the cost of raw materials can be reduced by 5-12% and energy consumption can be saved by 20-30%.
