At present, high purity polyacrylamide is mainly used in oil extraction, water treatment, mineral products screening and paper, textile and other four industries, the application range of these four industries is very wide, the following to introduce the role of high purity polyacrylamide in the paper industry production and use precautions. High purity polyacrylamide is a kind of paper auxiliaries commonly used in paper industry. Different types of high purity polyacrylamide and high purity polyacrylamide have different uses. The large molecular weight of high-purity polyacrylamide is generally used as a flocculant, the dispersant of smaller molecular weight is used as a dispersant, and the high-purity polyacrylamide can be used as a paper strengthening agent and other purposes. High purity polyacrylamide in the papermaking process can slow down the flocculation of the fiber in the papermaking process, so that the paper fiber can be evenly distributed in the water, so as to improve the uniformity of the mesh pulp and ensure the quality of pulp production.
The charge ions contained in the high purity polyacrylamide can enhance the adsorption of filler particles to the slurry fiber, thereby improving the retention rate of the filler, accelerating water filtration, saving energy, reducing the content of the filling in the white water, and improving the smoothness and opacity of the paper. It should be pointed out that in some places, the use of high-purity polyacrylamide alone will not achieve the expected effect, and other additives should be added according to the actual situation, such as aluminum sulfate, so that it has a better papermaking effect.
