How To Choose Polyacrylamide In Diffierent Industry

As we all know, Polyacrylamide(PAM) also named industry additives, It is widely used in sewage treatment. But it is not a panacea, not a model can solve all the problems, all the different sewage treatment standards, different sewage needs to use the corresponding product, there is a problem how to choose the appropriate flocculant? Here we will give you an introduction for this question. The nature of sewage produced by different enterprise,some are acidic water, alkaline water and some water, is neutral, some contain oil, some contain large amounts of organic matter, containing some color, some contain large amounts of sediment, as well as a variety of circumstances, nature of sewage have different situation. In general,Cationic Polyacrylamide has a good effect on acidic sewage,anionic polyacrylamide has a good effect on alkaline sewage.Of course, the water quality of neutral sewage is relatively alkaline and acidic sewage is easy to deal with, if the acidic water quality of sewage is too large, is generally difficult to handle, the usual approach is to add alkali to the sewage, adjust the pH of the sewage, so that Sewage to neutral the best. So the most easy to deal with, but also can save processing costs. Conversely, if the sewage showed alkaline strength, it is necessary to add acid to adjust the pH of the sewage. Sewage is neutral, not the kind of polyacrylamide can be the sewage treatment is good, to discharge standards, which have a more accurate selection problem, the usual practice is to do a small test in the laboratory, through Repeated experiments, select the best experimental model, and then in the actual production process to test whether the selected models in production is also appropriate.

Applications Of Polyacrylamide

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.
