Why Choose As Many Models As Possible for Polyacrylamide?

Polyacrylamide can be divided into four types: anionic, cationic, nonionic and zwitterionic. Each parameter index of dry PAM is also different, and its action basis and effect are also different. Different industries have different charges for wastewater, and different types of polyacrylamide treatment effects need to be used. This is the main reason why polyacrylamide needs to be selected.


1. The role of different dry powder polyacrylamide


According to the product's molecular weight, degree of hydrolysis, solid content and other indicators, anionic and non-ionic polyacrylamides are divided into dozens of different types of polyacrylamides. Anionic and non-ionic polyacrylamide are mainly used to remove suspended particles, such as coarse particles, high-concentration particles, positively charged particles, and water with a neutral or alkaline pH value. Because the molecular chain of anionic polyacrylamide contains a certain number of polar groups to adsorb suspended solid particles in water, the bridge between the particles forms a larger flocculant. Therefore, it accelerates the deposition of particles in the suspension, has the effect of accelerating solution clarification and promoting filtration. Polyacrylamide anionic products are widely used in the treatment of chemical wastewater and waste liquid and the treatment of urban sewage, such as tap water industry, high turbidity water purification, cleaning, coal washing, mineral processing, metallurgy, iron and steel industry, zinc, aluminum processing industry, electronics industry water treatment industry.


2. The reason why dry powder polyacrylamide chooses more models as much as possible


However, in acidic or alkaline media, cationic polyacrylamide is cationic, and its molecular weight is generally lower than that of anionic or nonionic polyacrylamide. Cations are mainly used for sludge dewatering, papermaking wastewater flotation treatment, printing and dyeing wastewater flotation, alcohol plants, food plants, etc. Cation selection is mainly based on the different charges in sludge and wastewater to select more consistent products. Different models have different cationicity, molecular weight and charge density. Therefore, the more models you have to choose, the more cost-effective and suitable dry PAM you can choose for your customers.


Different user sites have different water quality charges. According to the characteristics of water quality, select cationic polyacrylamide, polyacrylamide anionic, zwitterionic polyacrylamide and so on. Through experimental tests, a model that is more suitable for the user's on-site use is determined, so that the user can meet the customer's processing requirements with a smaller dose, thereby effectively saving costs. Sinofloc Chemical is a company specializing in the integration of dry PAM supply chain resources, with a large number of different types of polyacrylamide. It can provide high-quality selection services for wastewater and sludge treatment in various industries, and can choose polyacrylamide products that are more suitable for customers, and have a higher cost performance.
