APAM anionic polyacrylamide
Anionic polyacrylamide (APAM) Product Description: anionic polyacrylamide (APAM) appearance is white powder, the molecular weight from 6 million to 25 million water solubility is good, can with arbitrary proportion are dissolved in water and insoluble in organic solvents. The effective pH range of 7 to 14, in neutral and alkaline medium showed the characteristics of high polymer electrolyte, and electrolyte salt sensitive, and high metal ions can be cross-linked to form insoluble gel.
Industrial wastewater treatment: for suspended particles, less, high concentration, particle with positive charge, the pH of the water is neutral or alkaline water, iron and steel plant wastewater, electroplating wastewater, metallurgical wastewater, coal washing wastewater and sewage treatment, the effect was the best. Drinking water treatment: many Chinese waterworks water from rivers, sediment and mineral content is high, compared with turbidity, although after precipitation and filtration, still can not meet the requirements and need to adding flocculant, dosage is 1 / 50 of the inorganic flocculant, but the effect is several times the inorganic flocculant for the organic polluted river water, the use of inorganic coagulant and a cationic polyacrylamide with better effect to use can be. Starch factory and alcohol plant loss of starch grains recovered: now a lot of a lot of starch factory wastewater containing starch, now cast and anionic polyacrylamide, so that starch particles flocculation, and then precipitate the filter press into a pancake, feed, alcohol plant alcohol can also adopt anionic polyacrylamide dehydration, filter for recovery. For river mud sedimentation. Used for paper dry strength agent.
In addition, the application of anionic polyacrylamide in the incense industry becomes more and more popular, anionic polyacrylamide product features: with good solubility, high viscosity, strong toughness, non flammable (less) smoke, no odor, non-toxic combustion characteristics; the product performance is stable, it avoids the plant powder and starch because of origin, time different, the bonding quality uneven, in the production of incense industry requires repeated debugging formula, so as to avoid product quality instability; incense products with smooth appearance, good shape, not easy to be broken; especially the cold dextrinize, no need to cook paste, the material directly mixed, mixed with water can produce, a long time after mixing material and water will not be placed dry hard material of the phenomenon can not be used, effective energy saving and convenient.
Corresponding to drinking water treatment of flocculation, should use food grade products for the right. In the "water supply and drainage standard specification for the implementation of manual" water treatment standards, the use of the non regular use of the non regular use of the 0.1mg/L, <0.1mg/L. In the water treatment process of coagulation aid application, desirable the standard value for the maximum dosage, the purchase of food grade quality, low residual polyacrylamide products, can ensure the health and safety of drinking water. A water plant, such as the use of polyacrylamide coagulant, the maximum dosage for 0.09% Mg / L, the use is Guangzhou polyacrylamide Engineering Center of the Ministry of chemical industry food grade and the filter effluent and factory water were not found with acrylamide monomer. It is believed that only to be able to control the quality of the use of products and dosage, then the use of polyacrylamide coagulation process, the health of drinking water is safe. Recently, the application of polyacrylamide organic product as water treatment agent will be expanded with the increase of water quality and water demand. Such as a water supply company for 97 years and 99 years, the amount has increased by about 8 times, using water from an increase to 6. The use of coagulation, coagulation, drainage. According to reports, in front of the filter investment plus poly propylene amide 0.015---0.05mg/L can increase filter week, enhance the ability to produce 10--16%. But in week increase the filter, the head loss also increases, the recoil time and strength also to a corresponding increase, but in contrast, adding filter aid of Polyacrylamide in the economy is cost-effective, dosage of polyacrylamide (PAM) filter, can prevent algae penetrate sand filter, in treatment of sudden accident, to ensure the quality of filtered water, the existing water supply its application filter process, received good results. Polyacrylamide organic products in the water treatment process and its enhanced flocculation, improve the filtration ability, improve water quality, increase the amount of water, saving cost advantage is more and more water supply enterprises willing to accept, polyacrylamide in drinking water treatment field applications are continually being developed, its prospect is optimistic
