Zwitterionic polyacrylamide (ACPAM) Product Features

Zwitterionic polyacrylamide molecules contain cationic and anionic base, it has the general characteristics of the use of cationic flocculants, showed more excellent performance. This kind of flocculant can be used in a wide range of pH value, has a higher water filtration capacity, the bottom of the filter cake moisture content, can also be used for strong acid leaching ore or from the metal containing acid catalyst to recover valuable metals. Zwitterion is by no means a mixture of anionic and cationic types. If the cationic polyacrylamide and anionic polyacrylamide used in conjunction with the reaction will produce precipitation. So zwitterionic products are the most ideal.

Zwitterionic polyacrylamide (ACPAM) technical parameters:

Appearance: white particles

Solid content: ≥ 88%

Molecular weight: 800-1000 (ten thousand)

Cationic degree: 5-60%

Anion degree: 0-10%

Solubility: ≤ 2

Amphoteric ion polyacrylamide main uses:

1) After oil field test, the performance of this new type of amphoteric ion-regulating water-blocking agent is higher than that of other single-ion characteristics.

2) The latest type of water treatment agent, when treating sewage and Sheung Shui on many occasions, ACPAM's performance in reducing surface tension is far greater than the ability of cations or anions to exist alone under the same conditions. In order to meet the requirements of reducing surface tension, anionic polyacrylamide and cationic polyacrylamide need to be used at the same time. If both are used improperly, white sediment will be produced and the use effect will be lost. ACPAM has the characteristics of zwitterion, it can complete the coordination of anions and cations, without any precipitation, especially for water quality is more complex or the nature of water often changes, the use of ACPAM as a flocculant is more convenient, the effect is better.

3) Sludge dewatering agent. As the nature of urban sewage discharge is becoming more and more complex, the requirements for sludge dewatering agent in sewage treatment are getting higher and higher. Single cationic polyacrylamide is not suitable for dewatering some sludge. Therefore, our company has developed ACPAM, a zwitterionic sludge dewatering agent, for this situation. After dewatering tests and use of various sludge, it is better than polyacrylamide with single ion characteristics. In particular, the use of zwitterionic polyacrylamide for sludge dewatering in refineries and chemical plants has a more prominent effect.

4) In the paper industry, as a papermaking chemical, its effect is more than PAM with single characteristics, especially in the retention and filtration assistance, it can improve the drainage speed under the mesh, reduce the loss of fiber filler, have a good effect on the wet end system, and promote and compensate the smoothness, strength and difference between the two sides of the paper.

In general, zwitterionic polyacrylamide is widely used in sludge dewatering fields such as urban sewage treatment plants, breweries, food factories, tanneries, paper mills, petrochemical plants, oil fields, metallurgy, chemical industry and cosmetics.

Principle: cationic polyacrylamide in acidic or alkaline medium are present positive, it is usually lower than the anionic or non-ionic polyacrylamide molecular weight, the clear clean sewage performance is mainly obtained by charge neutralization. The function of this kind of flocculant is mainly flocculation with negative charge, with turbidity removal, decolorization function. In alcohol factory, monosodium glutamate factory, sugar factory, meat products factory, beverage factory, printing and dyeing factory wastewater treatment with cationic polyacrylamide than with anionic polyacrylamide, non-ionic polyacrylamide or anionic polyacrylamide.

Product Application:

Mainly used as a flocculant: for suspended particles, coarse, high concentration, particles with positive charge, water PH value is neutral or alkaline sewage, because the anionic polyacrylamide molecular chain contains a certain amount of polar base can adsorb suspended solid particles in water, so that the bridge between the particles to form a large flocs. Therefore, it accelerates the sedimentation of particles in the suspension, has a very obvious effect on accelerating the clarification of the solution and promoting filtration. The product is widely used in chemical industry wastewater, waste liquid treatment, municipal sewage treatment.

1. Water industry, high turbidity water purification, sedimentation, coal washing, mineral processing, metallurgy, iron and steel industry, zinc, aluminum processing industry, electronic industry and other water treatment. It is widely used in petroleum industry, oil production, drilling mud, waste mud treatment, preventing water channeling, reducing friction, improving oil recovery and tertiary oil recovery.

2. Used for textile sizing agent, stable slurry performance, less pulp, low fabric breakage rate, smooth cloth.

3. Used in the paper industry, one is to improve the retention rate of fillers, pigments, etc. In order to reduce the loss of raw materials and pollution to the environment; The second 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 improve visual and printing performance. Zwitterionic polyacrylamide has more excellent performance because it contains cationic and anionic groups in its molecules, which has the characteristics of general cationic flocculants. This kind of flocculant can be used in a wide range of pH value, has a higher water filtration capacity, the bottom of the filter cake moisture content, can also be used for strong acid leaching ore or from the metal containing acid catalyst to recover valuable metals.

4. Used in food and tea wrapping paper, other industries, food industry, used in cane sugar, beet sugar production in the clarification of cane juice and syrup phosphorus float extraction.

5. Enzyme preparation fermentation liquid flocculation clarification industry

6. It is used for the recovery of feed protein, with stable quality and good performance. The recovered protein powder has no adverse effects on the survival rate and weight gain of chickens, and has no adverse effects on laying eggs. Synthetic resin coatings, civil grouting materials, water blocking, building materials industry, cement quality improvement, adhesive for construction industry, joint filling repair and water blocking agent, soil improvement, electroplating industry, printing and dyeing industry, etc. The effect of inorganic salt is several times or tens of times higher, because this kind of wastewater generally has negative charge. At present, the use of water-soluble azo initiator AIBA, etc., has been able to increase its molecular weight to more than 10 million.

Packing and storage of zwitterionic polyacrylamide (CPAM):

This product is non-toxic, pay attention to moisture, rain, avoid sun exposure. Storage period: 2 years, 25kg paper bag (lined with plastic bag outside the plastic kraft paper bag).
