Chinese name: PAM (Polyacrylamide) Jane said: PAM Polyacrylamide as water-soluble polymer, insoluble in most organic solvents, has good flocculation sex, can reduce the friction resistance between liquid, by ion characteristic points can be divided into non-ionic and anionic, cationic and amphoteric four types.

Polyacrylamide is using acrylamide as monomer (acrylamide), by benzoyl peroxide (BPO) polymerization.Operation process is as follows (or you can find books about polymer chemistry) : in three flask, dissolved the acrylamide concentration (10%) in distilled water, access to the system of nitrogen, after 30 minutes, add a certain amount of BPO (BPO dosing amount depends on how big you want molecular weight polyacrylamide, BPO add, the more the smaller molecular weight polyacrylamide), mount the reflux condenser pipe, mixing device, began to stir, and at the same time water bath heating from around 50 ℃, reaction, the reaction should be continued for nitrogen.As the reaction, the system viscosity increased.An hour later, reaction stops.Pour the reactants in the beaker, into the beaker slowly adding anhydrous ethanol or acetone, and stir constantly, this is PAM start leaching, when there will be no white solid precipitation, the white solid under infrared lamp drying, grinding to powder for a quick polyacrylamide.

Cationic polyacrylamide (CPAM) is a linear polymer compound, because it has many active groups, with many substances affinity and adsorption can be formed hydrogen bonds.Mainly flocculation negatively charged colloid, except the turbidity, decoloring, adsorption, adhesion, and other functions, suitable for dyeing, papermaking, food, building, metallurgy, mineral processing, coal, oil field, aquatic products processing and fermentation industries such as waste water treatment of organic colloid content is higher, especially suitable for urban sewage, urban sewage sludge, sludge and other industrial sludge dewatering treatment

Sewage and organic waste water processing: the product in acidic or alkaline medium is electropositive, so that the suspended particles in wastewater with negatively charged sewage flocculation precipitation, clarification is very effective, such as alcohol plant waste water, brewery wastewater and gourmet powder factory wastewater, sugar refinery wastewater, meat food factory waste water, beverage factory waste water, textile dyeing wastewater, etc., with cationic polyacrylamide than with anionic polyacrylamide and nonionic polyacrylamide or inorganic salt effect is several times or tens times higher, because this kind of wastewater with negatively charged.

Water plant water treatment flocculant: the product has the advantages of low dosage, the effect is good,


Cost low characteristic, especially and inorganic flocculant compound with use effect is better.

Oilfield chemicals, such as clay expansion agent, oil field acidizing with thickener is tasted, etc.

Papermaking additives: cationic PA paper strengthening agent is a kind of water-soluble cationic polymer containing amino formyl, increased, retention, leaching, and other functions, can effectively improve the strength of the paper.At the same time the product is also a kind of efficient dispersant.
