Description

Anionic polyacrylamide (APAM) is white powder, molecular weight from 6 million to 25 million water solubility, can be dissolved in water in any proportion and insoluble in organic solvents. The effective pH range is 7 to 14, it has the characteristics of a high polymer electrolyte in a neutral alkaline medium, is sensitive to salt electrolytes, and can cross link with high price metal ions to form an insoluble gel.

Application

Industrial Wastewater Treatment

It has better effect for most industrial wastewater. Such as suspension particles, higher concentration, particle with Yang electric load, water ph value is neutral or alkaline sewage, steel plant wastewater, electroplating plant wastewater, metallurgical waste water, wash coal waste water and other sewage treatment.

Drinking Water Treatment

Many water plants in China come from rivers, sediment and mineral content is high, relatively turbidity, although after precipitation filtration, still can not meet the requirements, need to add flocculant, dosage is inorganic flocculant 1/50, but the effect is several times of inorganic flocculant, For the river water with serious organic pollution, inorganic flocculant and cationic polyacrylamide can be used to achieve better results.

Recovery of Lost Starch Distillers from Amylating Plants and Distillers

Many amylated plant wastewater contains a lot of starch, now add anionic polyacrylamide, so that starch particles flocculate precipitate, and then the sediment is filtered by the filter press into cake shape, can be used as feed, alcohol in the alcohol factory can also use anionic polyacrylamide dehydration, press filtration for recovery. Used for river mud settlement. Used as dry strength agent for paper making. 

Used for papermaking auxiliaries and auxiliaries. Adding a trace amount of PAM-LB-3 anionic polyacrylamide to the pump type pulp storage tank before paper making can increase the retention of fillers and fine fibers in the water by 20-30%. It can save 20-30kg pulp per ton.

For example, in the process of coal washing, a large amount of waste water is generated, which is directly discharged and pollutes the environment. It must be recycled after clearing, and the coal slime in the water is also valuable, but it is time-consuming and laborious to rely on natural settlement, and the water is not clear.

In addition, the application of anionic polyacrylamide in the fragrance industry is becoming more and more popular, anionic polyacrylamide product features: good solubility, high viscosity, toughness, flammable no (less) smoke, no smell, non-toxic characteristics; The product performance is stable, to avoid other plant glue powder and ordinary starch due to different origin, time, bond quality is uneven, in the incense production need to debug the formula repeatedly, so as not to cause product quality instability; The appearance of incense products is smooth and smooth, good shape, and not easy to break; In particular, its cold water gelatinization, no need to boil, the material is directly mixed evenly, and water mixing can be produced, and the material mixed with water will not be dry and hard to use for a long time, which effectively saves energy and is convenient.

EFFECT

The incense billet (incense product) made of this product has smooth appearance, no fracture, no mold spot, strong folding resistance, good product color, no fading after drying, sufficient ignition time, good flammability, and no "broken" flame out of the iron tooth plate, which is conducive to the improvement of the dispersion rate of the effective ingredients of mosquito-repellent incense and can reduce the loss of the finished product in the drying process. It can greatly reduce the labor intensity of workers and improve work efficiency. In addition, this product has no pollution to the environment and can meet the requirements of green environmental protection products.

Economic Benefits

APAM can reduce raw material costs by 5-12% and save energy consumption by 20-30%.
