Some treatment ranges corresponding to different types of polyacrylamide

2026-01-07
Polyacrylamide, also known as “auxiliary agent for various industries”, is actually a general term encompassing three major types. Today, let’s delve into these types. Anionic polyacrylamide: 1. It is suitable for sewage with suspended particles, coarse particles, high concentration, positively charged particles, and neutral or alkaline water pH. Due to the presence of a certain amount of polar groups in the molecular chain of anionic polyacrylamide, it can adsorb suspended solid particles in water, forming bridges between particles to create large flocculants. Therefore, it accelerates the sedimentation of particles in the suspension, significantly accelerates the clarification of the solution, and promotes filtration and other effects. This product is widely used in the treatment of chemical industrial wastewater and waste liquids, municipal sewage treatment, tap water industry, purification and sedimentation of high turbidity water, coal washing, mineral processing, metallurgy, steel industry, zinc and aluminum processing, electronics industry, and other water treatments. 2. It is widely used in the petroleum industry, oil extraction, drilling mud, waste mud treatment, prevention of water channeling, reduction of friction, improvement of recovery efficiency, and tertiary oil recovery. 3. Used as a textile sizing agent, it has stable sizing performance, low sizing loss, low fabric breakage rate, and a smooth cloth surface. 4. In the paper industry, polyacrylamide is used for two purposes. Firstly, it can enhance the retention rate of fillers and pigments, thereby reducing the loss of raw materials and environmental pollution. Secondly, it can improve the strength of paper, including both dry and wet strength. Additionally, the use of polyacrylamide can also enhance the tear resistance and porosity of paper, improving visual and printing performance. It is also used in food and tea packaging paper. Flocculant-Polyacrylamide 5. In other industries, such as the food industry, it is used for clarifying cane juice and extracting sugar syrup through the phosphorus floatation method in the production of cane sugar and beet sugar. It is also used for flocculation and clarification of enzyme preparation fermentation broth in industry, as well as for the recovery of feed protein, ensuring stable quality and good performance. The recovered protein powder has no adverse effects on chicken survival rate, weight gain, and egg production. It is also used in synthetic resin coatings, as a water blocking material in civil engineering grouting, in the building materials industry to improve cement quality, as an adhesive in the construction industry, as a joint filler and water blocking agent, for soil improvement, in the electroplating industry, and in the printing and dyeing industry. Cationic polyacrylamide: Cationic polyacrylamide exhibits positive charge in both acidic and alkaline media. It typically has a lower molecular weight than anionic or nonionic polyacrylamide, and its performance in clarifying sewage is mainly achieved through charge neutralization. The primary function of this type of flocculant is to flocculate negatively charged particles, providing turbidity removal and decolorization capabilities. In wastewater treatment from alcohol plants, monosodium glutamate plants, sugar refineries, meat processing plants, beverage factories, printing and dyeing plants, etc., the use of cationic polyacrylamide yields several times or even tens of times higher efficiency than the use of anionic polyacrylamide, nonionic polyacrylamide, or inorganic salts, as these types of wastewater generally carry negative charges. Cationic polyacrylamide is suitable for specialized sludge dewatering machinery such as high-speed centrifuges, belt press filters, and plate and frame press filters. It features rapid flocculation, coarse flocs, resistance to compression and shear, good flocculation properties, and easy detachment from filter cloths. Therefore, it achieves a high dewatering rate, low liquid content in the filter cake, and low dosage, significantly reducing user costs. It can also be used for hydrochloric acid, medium-concentration sulfuric acid, and other liquids to separate and purify suspended solids contained therein. Therefore, this product is widely used in sludge dewatering processes in urban sewage treatment plants, breweries, food factories, tanneries, paper mills, petrochemical plants, oil fields, metallurgy, chemical industries, and cosmetics. Nonionic polyacrylamide: 1. Primarily used as a flocculant: Due to the presence of a certain amount of polar groups in its molecular chain, it can adsorb suspended solid particles in water, forming large flocculated aggregates between the particles. It accelerates the sedimentation of particles in the suspension, significantly enhancing the clarification of the solution and facilitating filtration. It is widely used in the treatment of chemical industrial wastewater and waste liquids, as well as municipal wastewater treatment. Especially when the wastewater is acidic, this product is most suitable for use. It can be used in combination with inorganic flocculants such as polyferric sulfate and polyaluminum chloride. 2. It is widely used in the petroleum industry, oil extraction, drilling mud, waste mud treatment, prevention of water channeling, reduction of friction, improvement of recovery efficiency, and tertiary oil recovery. 3. Used as a textile sizing agent, it features stable sizing performance, minimal sizing loss, low fabric breakage rate, and a smooth cloth surface. 4. In the paper industry, polyacrylamide is used for two purposes. Firstly, it can improve the retention rate of fillers and pigments, thereby reducing the loss of raw materials and environmental pollution. Secondly, it can enhance the strength of paper, including both dry and wet strength. Additionally, the use of polyacrylamide can also improve the tear resistance and porosity of paper, thus enhancing visual and printing performance. It is also used in food and tea packaging paper. 5.
