The anionic polyacrylamide series is a water-soluble linear polymer synthesized with high degree of polymerization. It is supplied in a dust-free and free-flowing microparticle state or in a gel form, completely soluble in water, and is rapidly dissolved due to its microparticle form. Different types of polyacrylamides have different reactive groups, which can flocculate different suspended particles and facilitate filtration and separation. This series of products is almost insoluble in any organic solvent and is widely soluble in water. It is widely used in many industries for flocculation, thickening, bonding, scale inhibition, stable colloid, drag reduction, film formation, gelation and biomaterials.
Appearance: white particles or powder; molecular weight: 500 to 25 million
1. Exploration and development of oil fields, exploration of geology, water conservancy and coal. It can be used as an additive for drilling mud material to reduce the friction of the drill bit, prolong the service life of the drill bit, increase the drilling speed and footage, reduce the blockage during the drill change, and prevent the well collapse effect. In addition, it is also used for thickened water flooding. , fracturing fluid and selective water shutoff have a significant effect on improving oil recovery rate;
2. For the purification of drinking water, the purification of river water, the treatment of municipal sludge, urban domestic wastewater and industrial wastewater; for example:
a. The water source of many waterworks in China comes from the rivers. The sediment and mineral content are high and turbid. Although it has not been able to meet the requirements after sedimentation and filtration, it is necessary to add flocculant, and the dosage is 1/50 of the inorganic flocculant. However, the effect is several times that of the inorganic flocculant. For the river water with serious organic pollution, the inorganic flocculant and the anionic polyacrylamide can be used together.
b. Industrial wastewater treatment: for suspended particles, higher concentration, higher concentration of particles, positive charge of water, neutral or alkaline wastewater, steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, etc. ,best effect.
3. Clarification of caustic soda in the paper industry, fiber dispersant, can improve the degree of beating, filler retention agent, paper reinforcing agent, can be used to improve the drainage rate and white water recovery; for example: for papermaking auxiliaries, helpers . The addition of a small amount of PAM-LB-3 anionic polyacrylamide to the pump-type reservoir before papermaking can increase the retention of fillers and fine fibers in the water by 20-30%. You can save 20-30kg of pulp per ton.
4. It is applied to the sizing of textile and carpet industry, cement quick-setting, synthetic resin coating. Photosensitive polymers, binders, dispersants, and agricultural soil gels, mud stabilizers, anionic polyacrylamide-soil improvers;
5. As a clarifying agent for sugar juice in the sugar industry;
6, can be used as aquafeed additive and binder; for example: adding anionic polyacrylamide, so that the starch particles flocculate and precipitate, and then the precipitate is filtered by a filter press into a cake, which can be used as feed.
7, recycling. For example: the recovery of oil from the refinery water treatment plant; the large amount of wastewater generated during the coal washing process, which directly discharges the polluted environment, must be recycled and recycled, and the recovery of the coal slime is also valuable, but it takes time and effort to rely on natural settlement. At the same time, the water is not clear; and the alcohol in the alcohol factory can also be dehydrated by anionic polyacrylamide and recycled by pressure filtration.
8. The application of anionic polyacrylamide in the fragrance industry is also becoming more and more popular. Its characteristics are: good solubility, high viscosity, strong toughness, flammable (less) smoke, no odor, no toxicity; The product performance is stable, avoiding other plant gum powder and ordinary starch due to different origin and time, and the bonding quality is uneven. In the production of the fragrance industry, the formula needs to be repeatedly tested to avoid the instability of the product quality; the appearance of the fragrance product is smooth and smooth. It is well formed and not easy to be broken; especially its cold water can be gelatinized, no need to cook paste, the material can be directly mixed evenly, and water can be mixed to produce, and the material after mixing with water will not be dry or hard for a long time. The phenomenon of use occurs, which effectively saves energy and facilitates production operations. Use effect: The fragrance (fragrance product) made with this product has smooth appearance, no breakage, no mildew, strong folding resistance, good product color, no fading after baking, good ignition time, good flammability, iron The toothed disc is not "broken" and extinguished, which is beneficial to the increase of the volatilization rate of the active ingredients of the mosquito coil and can reduce the loss of the finished product during the drying process. At the same time, the labor intensity of the worker can be greatly reduced and the work efficiency can be improved. In addition, this product has no pollution to the environment and can meet the requirements of products in terms of environmental protection.
1. When preparing polyacrylamide aqueous solution, it should not be prepared and stored in iron container. It should be carried out in enamel, galvanized, aluminum or plastic drum.
2. When polyacrylamide is dissolved, care should be taken to slowly add the product to the dissolver with stirring and heating measures. Avoid solidification, prepare the solution at a suitable temperature, and avoid machinery that has been used for a long time. Cut.
3, polyacrylamide aqueous solution should be used now, when the solution is placed for a long time, its performance will be gradually reduced depending on the water quality, we must pay attention to not put it for a long time.
