Application of anionic polyacrylamide (AN934 AN945 AN956)

Polyscrylamide (PAM) is a water-soluble linear polymer made by polymerization of acrylamide monomer. The chemical properties of monomer acrylamide is very active, and a series of chemical reactions can be carried out in the double bond and amide group, using different processes, importing different functional groups, you can get different charge products: anionic, cationic, non-ionic, amphoteric polyacrylamide.

Anionic polyacrylamide

1, mainly used as flocculant: for suspended particles, coarse, high concentration, particles with positive charge, water PH value is neutral or alkaline sewage, because anionic polyacrylamide molecular chain contains a discharge of polar base can absorb suspended solid particles in water, so that the formation of a large flocculant bridge between particles. Therefore, it speeds up the sedimentation of particles in the suspension, has a very obvious effect of speeding up the cleaning of the solution, promoting filtration and so on. The product is widely used in chemical industry waste water, waste liquid treatment, municipal sewage treatment. Tap water industry, turbid water purification, cleaning, coal washing, mineral processing, metallurgy, iron and steel industry, zinc, aluminum processing industry, electronic industry and other water management. 2, used in the petroleum industry, oil recovery, drilling mud, waste mud treatment, prevent water channelling, reduce friction, improve recovery, three oil recovery has been widely used. 3, used for textile sizing agent, slurry performance stability, less falling pulp, fabric breakage rate is low, clean cloth.

4, used in paper industry, one is to improve the retention rate of filler, pigment and so on. In order to reduce the loss of raw materials and environmental pollution: two is 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 change the visual and printing performance, but also used in food and tea wrapping paper. 5, other industries, food industry, used for sugarcane sugar, sugar beet sugar production sugar juice clear and syrup phosphorus float extraction. Enzyme preparation fermented liquid flocculating settling 淸 industry, also used in feed protein recycling, mass quantity left, stability, recovery of protein powder to chickens and raising the survival rate of weight gain, no adverse effects of egg production, synthetic resin coating, plus or minus built water plugging grouting materials, building materials industry, improve the quality of cement, construction adhesive, caulking repair and plugging agent, Soil improvement, electroplating industry, printing and dyeing industry, etc.

Cationic polyacrylamide

Cationic polyacrylamide in acidic or alkaline media are positive, it is usually lower than anionic or non-ionic polyacrylamide molecular weight, its cleaning sewage performance is mainly through charge neutralization. The function of this kind of flocculant is mainly flocculating with a negative charge, with turbidity removal, decolorization function. In liquor factory, gourmet drinks factory, sugar factory, meat products factory, beverage factory, printing and dyeing factory and other wastewater treatment with cationic polyacrylamide than anionic polyacrylamide, non-ionic polyacrylamide or inorganic salt effect is several times or dozens of times, because this kind of wastewater with a negative charge.

Cationic polyacrylamide is suitable for high speed centrifuge, belt filter press, plate and frame filter press and other special sludge dewatering machinery, has the characteristics of fast forming flocculation, coarse flocculation, extrusion and shearing resistance, good agglomeration, easy to peel with the press cloth and so on. So the dehydration rate is high, the filter cake liquid content is low, the dosage is small, can greatly reduce the user use cost. It can also be used for hydrochloric acid, medium concentration sulfuric acid and other liquids to separate and purify the suspended turbidity substances contained in them. Therefore, the product is widely used in sewage treatment plant, beer plant, food factory, tannery, paper mill, petrochemical plant, oil field, metallurgy, chemical industry and cosmetics and other sludge dewatering treatment.

Three, non-ionic polyacrylamide

[Product Application]

1, mainly used as flocculant: because its molecular chain contains a discharge of polar genes can absorb suspended solid particles in water, so that the formation of large flocculant between particles. It accelerates the sedimentation of particles in suspension, has very obvious effect of speeding up the cleaning of solution, promoting filtration and so on. It is widely used in the treatment of chemical industrial wastewater, waste liquid, municipal sewage treatment. Especially when the sewage is acidic, using this product is the most suitable. It can be used with inorganic flocculants such as poly-iron and poly-aluminum.

2, used in the petroleum industry, oil recovery, drilling mud, waste mud treatment, prevent water channelling, reduce friction, improve recovery, three oil recovery has been widely used.

3, used for textile sizing agent, slurry stable performance, less falling pulp, fabric breakage rate is low, cloth and clean.

4, for paper industry, one is to improve the retention rate of filler, pigment, etc. To reduce the loss of raw materials and environmental pollution; Two is to improve the strength of the paper (including dry strength and wet strength), in addition, the use of PAM can also improve the tear resistance and porosity of the paper, to improve the visual and printing performance, but also used in food and tea wrapping paper.

5. Tho ta industry, food industry, used for sugar cane sugar, sugar beet sugar production sugar juice clear and syrup phosphorus float extraction. Enzyme preparation to send liquid yeast flocculation settling 淸 industry, also used in feed protein recovery, stable quality, good performance, recovery of protein powder for chickens, the survival rate of high and weight gain, no adverse effects of egg production, synthetic resin coating, water plugging grouting material is built on the building materials industry, improve the quality of cement, construction industry adhesives, caulking repair and plugging agent, Soil improvement, electroplating industry, dyeing industry, etc.

Four, amphoteric ion polyacrylamide

Product form: amphoteric ion polyacrylamide (ACPAM) appearance is white powder. Product features: amphoteric ion polyacrylamide because of the molecule containing cationic base and anionic base, it has the use of general cationic flocculant characteristics, showing more excellent performance. This type of flocculant can be used at large normal PH values, with higher water filtration, lower cake moisture content, and can also be used for strong acid leaching of ore or recovery of valuable metals from metal containing acid catalysts.

Amphoteric ionic is not a mixture of anionic and cationic. If the use of cationic polyacrylamide and anionic polyacrylamide will react to produce precipitation. So amphoteric ion products are ideal. Main uses:

Profile control and water plugging agent in oil field, combined with crosslinking agent, stable drainage agent and coagulant, can produce high strength coagulant gel plugging agent with important polymer gel and resin gel. The gel time can be controlled to adapt to different geological clearance conditions by blocking formation pores and fractures through adhesion and physical blockage and adjusting the proportion. All kinds of oil pollution, organic, inorganic, sewage, complex sewage treatment. In sewage systems with constant PH variation. Used for sludge dewatering. Used as auxiliary in paper making. Packaging and storage:

This product is non-toxic, pay attention to moistureproof, rain proof, avoid sun exposure. Storage life: 2 years,25kg paper bags (lined with plastic bags and pasted with plastic cow skin paper bags).
