Polyacrylamide (PAM)is the polymer of acrylamide monomer homopolymerization or copolymerization under the action of initiator. It is one of the most widely used water-soluble polymer materials. It is mainly used in petroleum exploitation, water treatment, Textile, paper, mineral processing, medicine, agriculture and other industries.
The Applications of Polyacrylamide :
1.Mainly used as flocculant for suspended particles, coarse, high concentration, particle with positive charge, water pH value is neutral or alkaline water, because of solid particles of anionic polyacrylamide molecular chain containing a certain amount of polar suspension can absorb water, make the bridge between particles into large flocs. It accelerated the suspension the settlement of particles have obvious to speed up the solution of clarification, promote the filtering effect. The products are widely used in chemical industrial wastewater, wastewater treatment, municipal sewage treatment industry. Tap water, purification, high turbidity water cleaning, washing, dressing, metallurgy, steel, zinc, aluminum processing, electronic water treatment industrial etc.
2.Polyacrylamide used in the oil industry, oil production, drilling mud, waste mud treatment, prevent water channeling, reduce friction, improve oil recovery, three oil extraction has been widely used.
3.Polyacrylamide for textile sizing agent, sizing performance-stability, falls-pulp less, fabric breakage rate is low, clean cloth.
4.Polyacrylamide used in the papermaking industry, one is to improve the packing, pigmentretention rate. In order to reduce the loss of raw materials and pollution to the environment; the two is to improve the strength of paper (including dry and wet strength), in addition, you can also use the PAM to improve the paper tear resistance and porous, to improve vision and printing performance, also used in food and tea packagingpaper.
5.In other industries, the food industry, for cane sugar, beet sugar production in sugarcane juice clarificationandsyrupphosphorous floatationextraction.Enzyme fermentation liquid clarification industry, also for the recovery of protein feed, stable quality, good performance, recovery of protein powder on improving the survival rate of chicken and egg weight, no adverse effects, synthetic resin coating, of grouting material for water plugging, building materials industry, improve the quality of cement, construction adhesives, caulking repair and water plugging agent, soil improvement, electroplating industry, printing and dyeing industry.
