Pam polyacrylamide is currently mainly used in oil mining, 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 polyacrylamide in paper industry production and use precautions.
Pam polyacrylamide is a kind of paper auxiliaries commonly used in paper industry. Different types of pam and pam have different uses. pam large molecular weight of polyacrylamide is generally used to do flocculant, smaller molecular weight dispersant as dispersant, polyacrylamide can be used as a paper enhancer and other purposes. pam in the papermaking process can slow down the flocculation settlement of the fiber in the papermaking process, so that the paper fiber can be evenly distributed in the water, so as to improve the mesh pulp uniformity, ensure the quality of paper production.
The charge ions contained in pam can enhance the adsorption of filler particles on the slurry fiber, so as to improve the retention rate of the filler, accelerate the water filtration, reduce the content of the filler in white water, improve the smoothness and opacity of the paper. It should be pointed out that in some places alone with polyacrylamide will not achieve the desired effect, at this time should be added according to the actual situation of other additives, such as aluminum sulfate, so that it has a better papermaking effect.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
