High Efficiency of Cationic Polyacrylamide

Cationic polyacrylamide PAM is a high-efficiency additive and a good auxiliary for purifying the environment. When storing cationic polyacrylamide, there are many details to pay attention to, otherwise the effect will be greatly reduced. Correct use of cationic polyacrylamide is very important. Only the correct operation of polyacrylamide can ensure the solution viscosity and flocculation effect of cationic polyacrylamide.

It is very important to use them as formulations in industrial water treatment. In raw water treatment, the organic flocculant cationic polyacrylamide is used to replace the organic flocculant, and the purified water can be increased by more than 20% even if the sedimentation tank is not modified. Many large and medium cities use polyacrylamide as a supplement when water supply is important or the water quality is poor. In raw water treatment, cationic polyacrylamide and activated carbon can be used for coagulation and clarification of suspended particles in domestic water. In wastewater treatment, polyacrylamide can be used for sludge dewatering.

1. Cationic polyacrylamide can be used as a purifying agent for domestic water

This is because the tap water used in our daily life is purified by the tap water treatment plant, and these water resources contain a large number of microorganisms and suspended particles before treatment. If an appropriate proportion of polyacrylamide is added to the water, the cationic polyacrylamide can flocculate with the suspended particles in the water resource to form a precipitate, which helps to improve the purification efficiency of domestic water.

2. Cationic polyacrylamide can be used in the field of oil extraction

Because cationic polyacrylamide has adhesion and drag reduction property. In the field of oil extraction, newly mined oil is highly fluid and difficult to extract during drilling. However, when oil is recovered, an appropriate proportion of cationic polyacrylamide can be added to the newly recovered oil, and then the substance can be combined with the effective substances in the oil. At this time, it is beneficial to speed up crude oil extraction and improve crude oil recovery. In addition, when leakage occurs again at this time, an appropriate proportion of cationic polyacrylamide can also be added to the leakage to cause condensation reaction between the substance and the leaked oil, causing it to agglomerate and block the leakage.

3. Cationic polyacrylamide has good flocculation effect

Due to its long molecular chain, the long chain of large order has infinite adsorption surface area in water, and the flocculation effect is good. The long chains can be used to build bridges between particles, forming flocs of large particles and accelerating settling. Under the action of cationic polyacrylamide flocculation aids, double ionization compression may occur during the coagulation process of mud treated by water purification, which reduces the stability of particle aggregation. The particles are held together by molecular attraction, and the anions may be replaced by polymer anionic groups.

Chemical interactions between substances in water and suspended substances, consisting of cationic polyacrylamide polymers and natural water, or between ions of previously added hydrolyzed coagulants, can be complex reactions. Since the molecular chains of cationic polyacrylamide are firmly attached to the surfaces of different particles, each solid-phase particle forms a polymeric bridge. In general, the use of cationic polyacrylamides of different ionic types varies widely. There are many factors that affect the performance of cationic polyacrylamide solutions. It is necessary to understand these influencing factors so that polyacrylamide can have better performance.
