Anionic polyacrylamide

Description :

Anionic polyacrylamide (APAM) is a water-soluble polymer mainly used for flocculation, sedimentation, and clarification treatment of various industrial wastewater, such as steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater, and sludge dewatering. It can also be used for clarifying and purifying drinking water. Due to the presence of a certain number of polar groups in the molecular chain of anionic polyacrylamide, it can adsorb solid particles suspended in water, bridging between particles or aggregating particles to form large flocs through charge neutralization. Therefore, it can accelerate the settling of particles in the suspension, significantly improve solution clarification, and promote filtration.

1. Various technical indicators can be adjusted according to user needs;

2. The test method is: GB/T 17514-2017;

3. Packaging: lined with plastic bags and covered with plastic coated kraft paper bags, each weighing 25KG.

[Product Features]:

1. Anionic polyacrylamide has good water solubility and can be completely dissolved in cold water.

2. Adding a small amount of anionic polyacrylamide can achieve a great flocculation effect. Generally, only 0.01-10ppm (0.01-10g/m3) needs to be added to fully exert its effect.

3. Simultaneously using anionic polyacrylamide and inorganic coagulants (such as polymeric ferric sulfate, polymeric aluminum chloride, iron salts, etc.) can demonstrate greater effectiveness.

【 Instructions 】:

1. When using, prepare a 0.1% concentration aqueous solution of anionic polyacrylamide and use neutral water that does not contain salt impurities.

2. When dissolving, sprinkle the anionic polyacrylamide evenly into the stirred water, and control the stirring speed at 100-300rpm. Moderate heating (<60 ° C) can accelerate dissolution.

3. Adjust the pH value of the treated solution to fully utilize the anionic polyacrylamide (select the optimal pH value and dosage of anionic polyacrylamide through experiments)

4. When adding anionic polyacrylamide solution, the mixing with the treated liquid should be accelerated. After the formation of flocs, the stirring speed should be slowed down to facilitate the growth of flocs and accelerate sedimentation.

[Scope of Application]:

1. Anionic polyacrylamide is used as a sizing and finishing agent for fabric treatment, as well as a protective layer that can generate softness, wrinkle resistance, and mold resistance. By utilizing its strong hygroscopicity, it can reduce the breakage rate of fine yarn during spinning. Polyacrylamide as a post-treatment agent can prevent static electricity and flame retardancy of fabrics. When used as a printing and dyeing additive, polyacrylamide can enhance the adhesion and brightness of the product, and can also serve as a non silicone polymer stabilizer for bleaching.

2. Anionic polyacrylamide used as a flocculant: For wastewater with coarse, high concentration, positively charged particles, and neutral or alkaline pH values, anionic polyacrylamide molecular chains contain a certain amount of polar groups that can adsorb suspended solid particles in water, causing bridging between particles to form large flocculants. Therefore, it accelerates the settling of particles in the suspension, significantly improves the clarification of the solution, and promotes filtration and other effects. This product is widely used for the treatment of chemical industry wastewater and waste liquid, as well as municipal sewage treatment. Water treatment in industries such as tap water, purification of high turbidity water, settling, coal washing, mineral processing, metallurgy, steel industry, zinc and aluminum processing industry, and electronics industry.

3. Anionic polyacrylamide is widely used in the petroleum industry, oil extraction, drilling mud, waste mud treatment, prevention of water breakthrough, reduction of friction, improvement of oil recovery rate, and tertiary oil recovery.

4. Anionic polyacrylamide is used in the paper industry to improve the retention rate of fillers, pigments, and other materials. To reduce the loss of raw materials and environmental pollution; The second is to improve the strength of the paper (including dry strength and wet strength). In addition, using PAM can also enhance the paper's tear resistance and porosity to improve visual and printing performance. It is also used in food and tea packaging paper.

5. Anionic polyacrylamide is used in other industries, such as the food industry, for sugarcane juice clarification and syrup phosphate float extraction in the production of sugarcane sugar and beet sugar. Enzyme based fermentation broth is used in the coagulation and clarification industry, as well as in the recovery, stable quality, and good performance of feed protein. The recovered protein powder has no adverse effects on the survival rate, weight gain, and egg production of chickens. It is also used in the synthesis of resin coatings, water blocking materials for civil engineering grouting, building materials industry, cement quality improvement, construction industry adhesives, joint filling and repair and water blocking agents, soil improvement, electroplating industry, printing and dyeing industry, etc.

6. Anionic polyacrylamide can be used as a clarifying agent for mining wastewater and coal washing wastewater in the mining and coal preparation industries.
