The production process of emulsion polyacrylamide is environmentally friendly, and it also has great advantages in application, such as less insoluble matter, fast dissolution, and low loss. The biggest highlight is that the dissolution speed is only 3~10 minutes, which effectively solves the needs of some special fields, and is no less than traditional dry powder products in the applicable fields. Its main application areas are as follows:

1. Used in the textile printing and dyeing industry. Polyacrylamide is used as a printing and dyeing additive. Polyacrylamide is used as a soft, wrinkle-resistant, and mildew-resistant protective layer for fabric treatment. Utilizing its strong hygroscopicity, the breakage rate of spinning can be reduced. Polyacrylamide is used as a post-treatment agent to prevent the fabric from being statically flame-retardant.

2. Mainly used as a flocculant: due to anionic polyacrylamide, it accelerates the sedimentation of particles in the suspension, significantly accelerates the clarification of the solution, and promotes filtration. For suspended particles, coarser and high concentration. The particles have a positive charge, and the pH of the water is neutral or alkaline sewage. Therefore, the product is widely used in the treatment of chemical wastewater, waste liquid and municipal sewage. Water treatment in tap water industry, high turbidity water purification, precipitation, coal washing, mineral processing, metallurgy, steel industry, zinc, aluminum processing, electronics industry, etc.

3. Petroleum industry, oil production, drilling mud, waste mud treatment: prevent water channeling. Reduce friction. Improve recovery. Tertiary oil recovery is widely used.

4. Used in the paper industry: First, increase the retention rate of fillers and pigments. In order to reduce the loss of raw materials and environmental pollution, improve the strength of the paper and the tear resistance and porosity of the paper, and improve the visual and printing performance, it can also be used for food and tea packaging paper.

5. Industrial wastewater treatment: For suspended particles, the concentration is high. The particles are positively charged, the PH value of the water is neutral or alkaline sewage, and the sewage treatment effect of iron and steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other wastewater is obvious.

6. Starch factories and alcohol factories: Many starch factories now contain a large amount of starch in wastewater. Anionic polyacrylamide is added to flocculate and precipitate the starch particles, and then the precipitate is filtered into a cake through a filter press, which can be used as feed.
