Polyacrylamide (PAM) /nonionic polyacrylamide/cation polyacrylamide/anionic polyacrylamide,alias flocculant No. 3, is a water-soluble linear polymer formed by free radical polymerization of acrylamide (AM) monomer. Coagulation and flocculation process in water treatment,Polyacrylamide sds has good flocculation and can reduce friction between liquids Resistance can be divided into four types: anionic, cationic, nonionic and amphoteric according to ionic properties.
Polyacrylamide is a white powder particle, which can be dissolved in water in any proportion, the aqueous solution is uniform and transparent, and the viscosity of the aqueous solution increases significantly with the increase of the relative molecular weight of the polymer. PAM is insoluble in most organic solvents, such as formaldehyde, ethanol, acetone, ether, etc.
Polyacrylamide is a water-soluble polymer or polyelectrolyte,water purification chemicals. There are a certain number of polar groups in the PAM molecular chain, which can adsorb the solid particles suspended in the sewage, make bridges between the particles or through the charge neutralization, so that the particles can agglomerate to form large flocs. Therefore, polyacrylamide can accelerate the suspended solids. The sedimentation of the medium particles has a very obvious effect of accelerating the clarification of the solution and promoting filtration.
Polyacrylamide contains toxic unpolymerized acrylamide monomer. In the drinking water treatment stipulated in my country, the maximum allowable amount is 0.01mg/L. In order to prevent the degradation of polyacrylamide, the storage temperature of its aqueous solution should be controlled not to be higher than 40°C. In order to prevent exposure to sunlight, a small amount of stabilizer, such as sodium thiocyanate, sodium nitrite, etc., can be added to the solution. Polyacrylamide solid powder needs to be packed in iron drums covered with moisture-proof polyethylene bags or lined with polyethylene layers, and sealed to prevent exposure to high humidity.
Liquid polyacrylamide needs to be packaged and then placed in wooden barrels or iron barrels. The storage period is about 3 to 6 months. It needs to be stirred before use. The storage temperature should not be higher than 32°C and lower than 0°C.
China Dadmac,Poly Dadmac, PDADMAC can be widely used in industrial waste water and surface water purification as well as sludge thickening and dewatering. It can improve water clarity at a relatively low dose. It has good activity that accelerate the sedimentation rate. It is suitable for a wide range of pH 4-10.
This product can also be used in the colliery waste water, paper making waste water, oil field and oil refinery oily waste water and urban sewage treatment.
