Polyacrylamide polyacrylamide classification Description: polyacrylamide (PAM) for the water-soluble polymers, insoluble in most organic solvents, has good flocculation can reduce the frictional resistance between the liquids, by ionic character points divided into non-ionic, anionic, cationic and amphoteric type of four types.
Polyacrylamide technical indicators
Polyacrylamide Appearance: solid polyacrylamide as white or slightly yellow granules or powder; colloidal polyacrylamide is a colorless or slightly yellow transparent colloidal molecular weight: according to user requests, and the relative deviation of the nominal value of not more than 10%. degree of hydrolysis: the relative difference between the nominal value of not more than 2%, or according to a user request; non-ionic products, the degree of hydrolysis of not more than 5%.
Anionic polyacrylamide (APAM)
Anionic polyacrylamide (APAM) Product Description: anionic polyacrylamide (APAM) appearance of white powder, molecular weight of from 6 to 25 million water-soluble, can be dissolved in water in any proportion and insoluble in organic solvents effective. PH value in the range of 7-14, in a neutral alkaline medium was characteristic of a high polymer electrolyte, and the electrolyte salt sensitive and high metal ions can form insoluble cross-linked gel of industrial wastewater treatment: for the suspended particles, a relatively high concentration of positively charged particles, water PH value is neutral or alkaline water, iron and steel plant wastewater, electroplating plant wastewater, wastewater metallurgy, coal washing waste such as sewage treatment, drinking water treatment works best: my many waterworks water from rivers, sediment and mineral content is high, more turbid, though filtered through precipitation, still can not meet the requirements, needs adding flocculants, inorganic coagulant dosage is 1/50, but the effect is several times the inorganic flocculants for serious organic pollution of the river water can be inorganic coagulant and cationic polyacrylamide with better effect the loss of starch and starch factory recovery lees alcohol plant: now a lot of starch factory wastewater containing starch many now adding anionic polyacrylamide, starch particles flocculation and sedimentation, then precipitate by filter press filter press into a pie, can be used for feed, alcohol plant of alcohol can also be used anionic polyacrylamide dehydration, pressure recovered by filtration. river mud for sedimentation. dry strength agents for paper. for paper chemicals, the rate of co-agent in paper before opening ceremony slurry storage tank pump with traces of PAM-LB-3 anionic polyacrylamide can filler and water retention fines online 20-30% savings per ton of pulp 20-30kg example: a large amount of coal washing process wastewater discharged directly pollute the environment, must Simcheong after recycling, recycling water slime It is also of value, but by natural sedimentation, time-consuming, but water is not clear.
The company supplies industrial wastewater treatment with polyacrylamide Yuxin quality assurance, welcome to consult the discussion.
