Water Treatment Agent Pam Polymer Chemical Anionic Polyacrylamide Flocculant CAS 9003-05-8

Polyacrylamide (PAM) is a polymer compound formed by the polymerization of acrylamide monomers, with the chemical formula (C₃H₅NO)ₙ. In appearance, it is a hard glassy solid at room temperature, but in practical applications, it also has various forms such as dry powder and colloid. It is easily soluble in water and has advantages in many aqueous system applications, but it is insoluble in organic solvents such as ethanol, ether and methanol.

Chemical Properties
Polyacrylamide is relatively stable to heat. Its solid state softens only at 220-230°C, and its aqueous solution does not significantly degrade until temperatures above 110°C.
Physical Properties

Solubility in Water: It readily dissolves in clean water under rapid mechanical stirring, forming a transparent, viscous solution. Degradation occurs at temperatures above 40°C.

Stability: It exhibits moderate hygroscopicity and can be stored for long periods in a ventilated, dry place.

Viscosity: The viscosity of a polyacrylamide solution is linearly related to its molecular weight.

1. Flocculation: PAM can effectively aggregate dispersed particles through electrical neutralization and surface adsorption. In water treatment, it can quickly aggregate suspended particles in water to form larger floccules, which is convenient for subsequent precipitation or filtration to achieve the purpose of purifying water quality; in the field of mineral processing, it can separate mineral particles from gangue particles and improve mineral recovery rate.

2. Thickening effect: Adding PAM to the liquid can significantly increase the viscosity of the liquid. In the food industry, it can be used to adjust the consistency of products such as sauces and jams; in cosmetics, it can improve the texture of products such as lotions and creams.

3. Adhesion: It has a certain adhesion ability to many substances. In the papermaking industry, it helps to combine fibers and improve the strength of paper; in the construction field, it can be used as one of the components of adhesives.

4. Stability: Polyacrylamide has good thermal stability, and its performance will not change significantly within a certain temperature range. However, when the temperature is too high, molecular chain breakage may occur, affecting its use effect.

1. Water treatment field

- Sewage treatment: Whether it is urban domestic sewage or industrial wastewater treatment, polyacrylamide (PAM) plays a key role. For sewage containing a large amount of suspended particles and organic matter, anionic polyacrylamide (PAM) can precipitate impurities through flocculation to achieve the purpose of purifying water quality; cationic polyacrylamide (PAM) is often used to treat sewage containing negatively charged colloidal particles, such as sludge dewatering, which can effectively reduce the sludge water content.

- Drinking water treatment: In the water plant purification process, polyacrylamide (PAM) can be used as a coagulant and other flocculants to improve the flocculation effect, remove tiny particles, algae and organic matter in the water, and ensure the safety of drinking water.

2. Oil production field

- Drilling fluid additives: During the drilling process, polyacrylamide (PAM) can increase the viscosity of the drilling fluid, carry cuttings, stabilize the well wall, prevent well collapse and other problems, and improve drilling efficiency and safety.

- Oil displacement agent: After being injected into the underground oil layer, it can improve the oil displacement efficiency, expand the swept volume, make crude oil easier to extract, and improve the oil field recovery rate.

3. Papermaking industry

- Paper reinforcement agent: It can enhance the bonding force between paper fibers, improve the physical properties of paper such as tensile strength, bursting resistance, tear resistance, and improve the quality of paper.

- Retention and filtration aid: In the papermaking process, it helps to retain fillers, fine fibers, etc., reduce losses, and at the same time improve the filtration performance of paper and speed up papermaking.

4. Other fields

- Mining: In the process of ore screening, separation and purification, the flocculation effect of PAM can be used to improve mineral processing efficiency and reduce tailings discharge.

- Agriculture: As a soil conditioner, it can improve soil structure, enhance soil water retention and air permeability, prevent soil compaction, and is conducive to crop growth; it can also be used to prevent soil erosion. Spraying a solution containing PAM on slopes, dams, etc. can enhance the soil's ability to resist erosion.

- Food Industry: In some food processing processes, such as juice clarification and beer filtration, PAM can be used as a flocculant to remove impurities and improve the transparency and purity of the product. However, PAM used in the food industry has strict requirements on its purity and residual monomer content to ensure food safety.

1. Selection issues:

Different industries and application scenarios with different water qualities require the selection of appropriate PAM models. For example, when treating acidic sewage, cationic PAM may be more suitable; when treating alkaline sewage, anionic PAM may be more effective. Before use, be sure to conduct a small test and a machine test, and select the most matching model based on the experimental results to achieve the best treatment effect.

2. Dissolution issues

Dissolution water temperature: When dissolving PAM, the water temperature should not exceed 60°C, otherwise it may cause the molecular chain to break and affect its performance. Generally, it can be dissolved in room temperature water.

Dissolution time: It takes a certain amount of time for PAM to dissolve, and it should be stirred evenly to ensure that it is fully dissolved. The dissolution time of powdered PAM is usually between 30 minutes and 2 hours, depending on the product model and stirring conditions.

Dissolution water: It is recommended to use clean tap water for dissolution to avoid impurities in the water affecting the dissolution effect and performance of PAM.

3. Dosing issues

Dosage: The dosage should be adjusted according to the actual situation, not the more the better. Too much dosage will not only cause waste, but also make the water viscous, affecting subsequent treatment; insufficient dosage will not achieve the expected treatment effect.

Dosing method: batch dosing is usually better than one-time dosing. For example, adding 60% of the agent for the first time and stirring quickly, and then adding the remaining 40% after 1-2 minutes can significantly improve the floc strength.

4. Storage issues:

PAM should be stored in a cool and dry place, avoiding direct sunlight and humid environment. At the same time, keep away from acid, alkali and other chemical substances to prevent chemical reactions. If the packaging is damaged, it needs to be replaced in time to prevent the product from absorbing moisture and agglomerating, which reduces the efficiency of use.
