CAS No 9003-05-8 Flocculant 99%Min Polyacrylamide PAM

Product Detail

CAS: 9003-05-8

1.Acrylamide is usually a polymer with the head and tail bonded structure of acrylamide monomer, which is a hard, glassy solid at room temperature. Due to different manufacturing methods, the products are available in white powder, translucent beads and flakes, etc. Density 1.302g/cm3(23℃), glass transition temperature 153℃, softening temperature Chemicalbook 210℃. It has good thermal stability. Dissolved in water, the aqueous solution is clear and transparent, its viscosity becomes viscous with the increase of polymer molecular weight, and is logarithmically increasing or decreasing with the change of polymer concentration. Except for a few solvents such as acetic acid, acrylic acid, chloroacetic acid, ethylene glycol, glycerol and formamide, it is generally insoluble in organic solvents.

2.Free radical polymerization of acrylamide monomer, solution polymerization, reverse-phase emulsion polymerization, suspension polymerization and solid state polymerization can be used. It requires controllable molecular weight, easy water solubility and low residual monomer. Polyacrylamide is one of the most widely used water-soluble polymers with a large number of side-group acyl Chemicalbook amine groups on its molecular backbone. The chemical activity of the amide group is great and can generate a series of derivatives with a variety of compounds. Polyacrylamide has various functions such as flocculation, thickening, drag reduction, bonding, colloid stabilization, film formation and scale inhibition, etc. It is widely used in paper making, mining, coal washing, metallurgy, oil extraction and other industrial sectors, and is an important chemical for water treatment.

3.Polyacrylamide is non-toxic, high molecular weight, strong water solubility, can introduce various ionic groups and adjust the molecular weight to get specific performance, good adhesion to many solid surfaces and dissolved substances, can absorb and bridge with suspended particles dispersed in solution, so that suspended particles flocculate and facilitate filtration and separation.

Application

1.For sludge treatment, according to the characteristics of sludge, the corresponding PAM model specifications can be used, which can reasonably carry out sludge treatment before the sludge enters the filter press, and when de-drying, it causes large flocs, does not stick to the filter cloth of the filter press, and does not disperse when the filter press is long, and the flow mud cake is thick, and the de-drying rate number, and the water content of the filter cake is below 80%.

2.Other industries, for the recycling of concentrate feed protein, smooth quality, good performance, recycling of protein powder to improve the survival rate of chickens and weight gain, laying eggs without negative impact. Anti-corrosion coating construction Chemicalbook coating, civil engineering grouting raw materials plugging, building materials industry, improve the quality of concrete, construction industry adhesives, caulking repair and plugging liquid agent, land improvement, electroplating process industrial production, printing and dyeing plant industrial production, etc.
