Polyacrylamide characteristics 1: PAM) flocculation can make the suspended material by charge neutralization, adsorption bridging, flocculating action. 2) adhesion: can be through mechanical, physical, chemical role, play the role of adhesion. 3 resistance: PAM can effectively reduce the friction of the fluid, water to join trace PAM can reduce resistance 80% - 50. 4) thickening: PAM in neutral and acid conditions are thickening effect, when the pH value at 10 C above PAM easy to hydrolysis. When the semi network structure, the thickening will be more obvious. Polyacrylamide application Anionic polyacrylamide 1, mainly used as a flocculant: for suspended particles, coarse, high concentration, particle with positive charge, water pH is neutral or alkaline water, due to the anionic polyacrylamide molecular chain containing a certain amount of polar groups to adsorption of solid particles suspended in the water, etc. 2, used in petroleum industry, oil production, drilling mud, waste mud treatment, prevent water channeling, reduce friction, improve oil recovery, the three oil recovery has been widely used. Two, cationic polyacrylamide Cationic polyacrylamide in acidic or alkaline media showed positive electricity, it usually is lower than the molecular weight of anionic or non-ionic polyacrylamide, the performance of the Chengcheng clean sewage is mainly obtained by charge neutralization. Three, non ionic polyacrylamide Due to its molecular chain containing a certain amount of polar gene can adsorb the suspended solid particles, the particle formation of large flocs, it accelerated the settlement of particles in suspension, have very obvious to speed up the solution to clarify, promote the effect of filtration, widely used in chemical industry waste water, wastewater treatment, municipal sewage treatment. Four, gender ion polyacrylamide Product form: gender ion polyacrylamide (ACPAM) appearance is white powder. Product features: the two gender ion polyacrylamide containing cationic and anionic groups, it has the general characteristics of the use of cationic flocculant, the performance of the more excellent performance. The main purpose: oil field profile control and water plugging agent, and crosslinking agent, stabilizer, coagulant combined effect, the formation of an important polymer gel and resin gel of high strength agent gel plugging agent. Adapt to different geological conditions. A variety of oil, organic, inorganic, sewage, complex sewage treatment. PH change in the sewage system for sewage Sludge dewatering, papermaking additives.
