Polyacrylamide (PAM) is a linear organic high molecular polymer, and also a high molecular water treatment flocculant product. It can absorb suspended particles in water and act as a bridge between particles to make fine particles A relatively large floc is formed and the precipitation speed is accelerated. This process is called flocculation, because of its good flocculation effect, PAM is used as a flocculant in water treatment and is widely used in sewage treatment. Today, I will mainly introduce the use of polyacrylamide in the titanium dioxide industry, Polyacrylamide for titanium dioxide factory.
In the production process of titanium dioxide, the flocculant polyacrylamide is also used to settle the leached titanium solution. During the settlement process of the production process of titanium dioxide, the system after acid leaching and reduction is a complex system, which contains solubility Impurities and insoluble impurities. The sulfates of iron, vanadium, chromium, manganese and other metals are soluble impurities, which are removed in the process of crystallization or hydrolysis and washing with water. Most of the insoluble impurities, such as undecomposed titanium ore, sand particles, etc. can be removed by natural settlement by gravity. The other part of the insoluble impurities is the colloidal compound of silicon and aluminum, and some early hydrolyzed titanium. Although the amount is not large, it has high dynamic stability. It is necessary to add appropriate polyacrylamide flocculant to strengthen the settlement and clarification. process. The rational use of polyacrylamide flocculant in the production process of titanium dioxide simplifies the use link, directly reduces the production cost, and has the advantages of fast settling speed, Polyacrylamide for titanium dioxide factory, simple process and low production cost.
The wastewater from the titanium dioxide industry uses a large amount of acidic chemical products such as sulfuric acid in production, so the wastewater from the titanium dioxide plant is generally strongly acidic wastewater. Cationic polyacrylamide and non-ionic polyacrylamide are generally used to treat wastewater from titanium dioxide plants. The specific type of polyacrylamide to be used has to be confirmed through a small trial selection. Dongguan Capitel Chemical is a supply chain resource integration company focusing on the selection of polyacrylamide for titanium dioxide plants. We can provide customers with precise selection of small trials and select polyacrylamide products that are more suitable for customers.
