Product Introduction

The appearance of anionic polyacrylamide (APAM) is white powder with a molecular weight ranging from 8 million to 20 million. It is a water-soluble linear polymer synthesized with a high degree of polymerization. It is easily soluble in water, but almost insoluble in benzene, ether, lipids, General organic solvents such as acetone. It has valuable properties such as flocculant, thickening, shearing, drag reduction, and dispersibility. Mainly used to treat water flocculation, sedimentation, clarification and purification treatment. Therefore, it is widely used in oil extraction, mineral processing, coal washing, metallurgy, chemical industry, papermaking, textile, sugar, medicine, environmental protection, building materials, agriculture and other industries.

Product Usage

1. Industrial wastewater treatment: for coarser suspended particles, high concentration, positively charged ions, water ph value of neutral or alkaline sewage, steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other sewage treatment ,best effect.

2. Drinking water treatment: The water source of many waterworks in China comes from the rivers and reservoirs. The sediment and mineral content are high and relatively turbid. Although it has not been able to meet the requirements after sedimentation and filtration, flocculant needs to be added. In the past, water plants used inorganic flocculants, but the dosage was large, which caused the sludge volume to increase. Anionic polyacrylamide is used as flocculant, and the dosage is 1/50 of inorganic flocculation, but the effect is several times or even several times of inorganic flocculant. The combination of river water and cationic polyacrylamide with serious organic pollution is better.

3. Drilling mud material: In the exploration and development of oil fields and the exploration of geological water and coal, the additive used as drilling mud material can improve the service life of the drill bit, increase the drilling speed and footage, reduce the blockage during drilling, and prevent the collapse. The effect is obvious. It can also be used as a fracturing fluid for oil fields and a water blocking agent for profile control and water shutoff.

4. Oilfield tertiary oil displacement agent: It can adjust the rheology of injected water, increase the viscosity of the oil displacement liquid, improve the water flooding efficiency, reduce the water phase permeability in the formation, and make the water and oil flow forward at a constant speed. Its role is mainly used for tertiary oil recovery in oil fields. For every ton of polymer polyacrylamide product injected, it can collect about 100-150 tons of crude oil.

5. Papermaking Auxiliaries: The papermaking industry can be used as a clarification of caustic soda, a retention aid, a filter aid, and a paper dry and wet strength enhancer.

6. Used in the sugar industry as a clarifying agent for sugar juice; used as an additive and binder in aquatic feed;

Packaging and storage

1.The product uses 25kg outer layer PVC plastic woven bag and inner film two-layer packaging. Can also be packaged according to user requirements.

2.When storing and transporting, pay attention to heat and moisture, and dry powder products will absorb moisture and agglomerate when exposed for a long time. The number of stacking layers must not exceed 20 layers. The effective storage period is 2 years.

Anionic polyacrylamide is used for industrial wastewater treatment: for suspended particles, high concentration, positively charged particles, neutral or alkaline PH value of water, steel plant wastewater, electroplating plant

wastewater, metallurgical wastewater, coal washing wastewater and other wastewater treatment, the effect is good. Drinking water treatment: the water source of many water plants in my country comes from rivers, with high sediment

and mineral content, and is relatively turbid. Although it has been precipitated and filtered, it still cannot meet the requirements. It is necessary to add flocculants. The dosage is 1/50 of that of inorganic flocculants, but the effect

is several times that of inorganic flocculants. For rivers with serious organic pollution, inorganic flocculants and our company's cationic polyacrylamide can be used together for better results. Recovery of lost starch lees from starch plants and alcohol plants: many starch plants now have a lot of starch in their wastewater. Anionic polyacrylamide is now added to flocculate and precipitate starch particles, and then the precipitate is filtered through a filter press to become a cake, which can be used as feed. The alcohol in the alcohol plant can also be dehydrated with anionic polyacrylamide and recovered by filtration. It is used for river water slurry sedimentation. Used as papermaking dry strength agent. Used as papermaking auxiliary agent and rate-aiding agent. Adding a small amount of PAM-ASG-3 anionic polyacrylamide to the pump-type pulp storage tank before papermaking can increase the retention of fillers and fine fibers in the water on the net by 20-30%. It can save 20-30kg of pulp per ton.

1. Mainly used as flocculant: for suspended particles, coarse, high concentration, positively charged particles, and neutral or alkaline water, since the anionic polyacrylamide molecular chain contains a certain amount of

bases that can adsorb suspended solid particles in the water, so that the particles can form large floccules by bridging. Therefore, it accelerates the sedimentation of particles in the suspension, and has a very obvious effect of

accelerating the clarification of the solution and promoting filtration. This product is widely used in the treatment of chemical industrial wastewater and waste liquid, municipal sewage treatment. Water industry, high turbidity water

purification, sedimentation, coal washing, mineral processing, metallurgy, steel industry, zinc, aluminum processing industry, electronics industry and other water treatment.

2. It is widely used in the petroleum industry, oil production, drilling mud, waste mud treatment, prevention of water channeling, reduction of friction, improvement of recovery rate, and tertiary oil recovery.

3. It is used as a textile sizing agent, with stable slurry performance, less slurry falling, low fabric breakage rate, and smooth cloth surface.

4. It is used in the papermaking industry, first, to increase the retention rate of fillers and pigments. To reduce the loss of raw materials and pollution to the environment; secondly, to improve the strength of paper (including dry

strength and wet strength). In addition, the use of PAM can also improve the tear resistance and porosity of paper to improve visual and printing performance. It is also used in food and tea packaging paper.

5. Other industries: Food industry, used for cane juice clarification and syrup phosphorus flotation extraction in the production of cane sugar and beet sugar. Enzyme preparation fermentation liquid flocculation clarification

industry, also used for feed protein recovery, stable quality, good performance, the recovered protein powder has no adverse effects on the survival rate and weight gain of chickens and egg production, synthetic resin coatings, civil

engineering grouting materials water blocking, building materials industry,improve cement quality, construction industry adhesives, caulking repair and water blocking agents, soil improvement, electroplating industry, printing and dyeing industry, etc.
