Beyond its well-known applications in water treatment, Polyacrylamide (PAM) is an indispensable polymer in several other key industries, notably papermaking and mining. Its unique properties as a flocculant, retention aid, and thickener contribute significantly to process efficiency and product quality. As a dedicated manufacturer and supplier, we offer specialized PAM solutions tailored for these demanding sectors.

Polyacrylamide in Papermaking: Retention and Drainage Aids

In the papermaking industry, PAM is widely used as a retention and drainage aid. During the paper formation process, fine fibers and fillers need to be retained on the forming fabric while allowing water to drain away efficiently. PAM achieves this by:

  • Retention: PAM's long polymer chains can bridge between fine fibers, fillers (like clay or calcium carbonate), and the forming fabric. This action traps these particles, preventing them from passing through the fabric with the water. This leads to higher material retention, reducing raw material loss and improving the opacity and strength of the paper.
  • Drainage: By flocculating the fines and fillers, PAM also helps create a more open sheet structure, allowing water to drain more rapidly. This speeds up the papermaking process and reduces the energy required for drying the paper.

For papermaking applications, specific types of PAM, often with controlled molecular weight and charge density, are used to optimize retention and drainage without negatively impacting paper properties like smoothness or printability. When considering to buy Polyacrylamide for your paper mill, consulting with an experienced supplier is beneficial.

Polyacrylamide in Mining: Tailings Thickening and Water Recovery

The mining industry generates large volumes of tailings – residual materials from the ore extraction process. These tailings are typically a slurry of fine mineral particles in water. PAM plays a critical role in managing these tailings:

  • Tailings Thickening: PAM is used as a flocculant in thickeners to accelerate the settling of fine mineral particles. The polymer creates large flocs that settle rapidly to the bottom of the thickener, allowing clear water to be decanted and often reused in the mining process. This is crucial for managing large volumes of waste material and conserving water resources.
  • Water Recovery: By efficiently settling solids, PAM facilitates the recovery of process water from tailings slurries. This recycling of water is vital for sustainability, especially in water-scarce regions.
  • Improved Filtration: The flocs formed by PAM can also improve the dewatering characteristics of tailings, making them easier to handle and dispose of in a more environmentally sound manner.

In mining, anionic or nonionic PAM is commonly used for tailings thickening, with the specific choice depending on the mineralogy and water chemistry. As a reliable Polyacrylamide supplier, we offer products that meet the rigorous demands of the mining sector, helping companies achieve both operational efficiency and environmental compliance.
