Replacement non-ionic polyacrylamide
A non-ionic polyacrylamide product overview
Nonionic polyacrylamide is a water-soluble polymer or polyelectrolyte. Because its molecular chain contains a certain number of polar groups, it can adsorb solid particles suspended in water to bridge between particles or condense particles to form large flocs through charge neutralization. Therefore, it can accelerate the sedimentation of particles in the suspension, and has a very obvious effect of speeding up the solution clarification and promoting filtration. Zhengzhou Tianhe water purification Material Co., LTD. Non-ionic polyacrylamide is mainly used for various industrial wastewater flocculation sedimentation, precipitation clarification treatment. Such as papermaking and pulp waste water treatment, mineral processing and metal smelting process waste water treatment, iron and steel plant and stone processing plant waste water treatment.
Two, the use of non-ionic polyacrylamide in detail
The detailed uses of non-ionic polyacrylamide are as follows:
1, used for sewage treatment. It is more suitable to use non-ionic polyacrylamide as flocculant when the suspended sewage is acidic. At this time, PAM plays the role of adsorption bridge, so that suspended particles produce flocculation precipitation, to achieve the purpose of purifying sewage. Can also be used for the purification of tap water, especially with inorganic flocculants: polymeric aluminum chloride, polymeric aluminum chloride, alkali aluminum chloride, polymeric ferric sulfate and other use, in water treatment effect is good.
2, textile industry auxiliaries. Generally applicable to zhengzhou Tianhe non-ionic polyacrylamide (NPAM) as well, add some chemicals can be made into chemical sizing, used for textile sizing.
3, sand control and sand fixation. Non-ionic polyacrylamide solution (NPAM) was added to 0.3 concentration of crosslinking agent and sprayed on the desert to play the role of sand fixation
4, oil field profile control water agent. Non-ionic polyacrylamide (NPAM) is widely used as profile control and water plugging agent in oil field by combining with lignocellulose and adding certain chemical additives
5. Chemical grouting agent. Using 9.5 parts of Zhengzhou Tianhe non-ionic polyacrylamide (NPAM) and 0.5 parts of N, N-- methylene bisacrylamide miscible can be used as a chemical grouting agent for water plugging of dyke, foundation and tunnel
6. In mining industry. Usually use a lot of water, and then often need to recycle useful solids in the water, and the waste water purification recycling. The application of non-ionic polyacrylamide (NPAM) flocculants promotes the settling of solids, which increases production efficiency, reduces tailings loss and water consumption, reduces equipment investment and processing costs, and eliminates environmental pollution.
7. In the process of coal washing, the sedimentation and filtration of pulverized coal and slime are the main economic problems and pollution control problems. Non-ionic polyacrylamide (NPAM) series products can reduce soil coloring, pipeline clogging, pump maintenance and river pollution, improve productivity, recovery of coal powder and improve filtration rate, but also can make water completely clarified.
8. In the electrolytic refining process, the metal precipitation can be homogenized to make the coating brighter and improve the current efficiency.
9, in the inorganic fiber mud (asbestos-cement products) can make the formed asbestos-cement products drainage is improved, so that the strength of the asbestos slab is improved; In the insulation board, the combination of additive and fiber can be improved.
10. Can be used as additives for plastic film and agricultural film.
11, non-ionic polyacrylamide (NPAM) composite material can be used for ore deposits, ponds, DAMS, foundation grouting material.
12, in soil improvement, non-ionic polyacrylamide can enhance the firmness of soil aggregate structure, increase soil water content and soil structure load.
13, Non-ionic polyacrylamide (NPAM) gel can be used to separate substances to maintain biological activity, controlled release of drugs and enzyme embedding, protein electrophoresis, cell gel electrolyte.
Three, non - ionic polyacrylamide flocculation principle
The side group on the molecular chain of non-ionic polyacrylamide is an active amide group, which can undergo a variety of chemical reactions and obtain a variety of derivatives, but due to the adjacent gene effect, the reaction is often not complete.
Because non-ionic polyacrylamide (NPAM) is a high polymer or polyelectrolyte, its molecular chain contains a certain amount of polar genes can absorb suspended solid particles in water, so that the particles form a large flocculation bridge. Zhengzhou Tianhe non-ionic polyacrylamide to accelerate the sedimentation of particles in the suspension, has a very obvious speed up the solution of clarification, promote filtration and other effects.
Non-ionic polyacrylamide is a water-soluble polymer. According to the molecular chain contains a certain number of polar groups, by absorbing solid particles suspended in water, the particles can be bridged or the particles can be condensed into large flocs by charge neutralization. Therefore, it can accelerate the sedimentation of particles in the suspension, and has a very obvious effect of speeding up the solution clarification and promoting filtration. Mainly used in various industrial wastewater flocculation sedimentation, precipitation clarification treatment. Such as papermaking and pulp wastewater treatment, mineral processing and metal smelting process wastewater treatment, iron and steel plant and stone processing plant wastewater treatment and so on.
Four, the advantages of non-ionic polyacrylamide
The advantages of non-ionic polyacrylamide are mainly used as flocculants. Because the molecular chain contains a certain amount of polarity genes, it can absorb suspended solid particles in water, so that the particles bridge to form large flocs. Non-ionic polyacrylamide can accelerate the sedimentation of particles in suspension, has very obvious to speed up the clarification of the solution, promote filtration and other effects, widely used in the treatment of chemical industrial wastewater, waste liquid, municipal sewage treatment. Especially when the sewage is acidic, it is suitable to use this product. It can be used with inorganic flocculants such as poly-iron and poly-aluminum.
Five, non-ionic polyacrylamide correct packaging, storage, transportation methods
1, packaging: non-ionic polyacrylamide is a water-soluble polymer, so when packaging, must use a layer of lining film packaging to prevent the product from moisture, failure. The packing of this product is two kinds of woven bag lined with double layer polyethylene plastic or plastic kraft paper bag, each bag net weight 25㎏.
2, storage: non-ionic polyacrylamide is water-soluble chemical products, according to have a strong moisture absorption, must not be exposed, otherwise it is easy to agglomerate after moisture absorption, affecting the use effect. Therefore, keep in a dry place. Non-ionic polyacrylamide products have a shelf life of two years.
3, transportation: in transportation to try to avoid the sun and rain; Prevent packaging aging broken xun, resulting in loss of products.
